How Can We Help?

Do you have 5000 lumens and CRI 90+ screw-in bulbs?

I want 5000 lumens and CRI 90+ and screw-in. Recommend me products.

Based on the details provided, we would recommend our 5000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb or the 5000K Full Spectrum E26 BR30 LED Bulb.

NorthLux A19 vs Centric Daylight A21 Bulbs

I need bulbs to light an art studio. I am considering two of your products:

1. NorthLux A19 LED bulbs (5000K, 800lm)

2. Centric Daylight A21 LED bulbs (5000K, 1600lm)

Number 1 is marketed as being for art studio use whereas number 2 is more general-purpose, however from the specs it seems they are similar (same colour temp, same CRI). Is there a significant difference between these products other than brightness and power consumption?

If the quality of light from NorthLux is significantly higher I will use it, but if not then I prefer the brighter Centric bulbs (so I can use fewer bulbs in total).

We can confirm that the primary difference between the two products is the dimensions and lumen output, where the A21 bulb is slightly larger and has double the lumen output compared to our standard A19 bulbs. 

​That being said, it might be helpful to know that both will offer full spectrum output as well as a high CRI of 95+. As such, the quality of light will be identical though the output of the A21 will be comparatively greater. 

Can I use Northlux A19 5000K and simply not activate the dimmer?

I need bulbs for the makeup mirror in the pro photography portrait studio. The makeup mirror has a dimmer. Can I use Northlux 5000K and simply not activate the dimmer? Will dimmer in the circuit regardless of the setting be a problem? Is Northlux the best? Dimmer activation is not needed for use.

So long as the dimming function on the fixture is not utilized and is set to 100% brightness, we would not expect our A19 bulbs to encounter performance issues. That being said, please note that any adjustment with the dimmer may cause hardware damage. 

Do you have 40W flicker-free bulbs?

Do you think you might have 40 W flicker-free bulbs in the future? I need one for a lamp next to my reading chair, for reading at night.

While we are not aware of the specific product development plans, we would be more than happy to share your interest in that option with our team for future development! We can certainly understand the benefits that such an option could provide, and look forward to expanding our catalog in the future.

As an alternative, you may be interested in the SUPERWARM™ 1700K Flicker-Free A19 10W LED Bulb, which is a flicker-free 50W equivalent product that outputs a rosy warm color. 

Can you recommend a light fixture for your A19 bulbs?

I just purchased a 6-pack of the bulbs below for my home office. I'm hoping to achieve that natural sunlight feel. Can you recommend either a floor lamp or overhead light fixture that works well with these bulbs? 

While we unfortunately don't have any specific fixtures that we could recommend, it might be helpful to know that these items have slightly larger dimensions than standard A19 bulbs, and may not fit into all fixtures. ​

​That being said, we can confirm that the A21 bulbs use the same E26 base as standard North American A19 bulbs, and are not expected to have compatibility issues with the standard socket. 

We have attached a link to the product specification sheet below which features the measurements of the item, in the hopes that it is useful for your purchase planning process. 

A21 15W LED Bulb - Specification Sheet 

Do your bulbs and fixtures work on European current?

Do your bulbs and fixtures work on European current? I have fittings with electronic ballast. Will your tubes work with any type of ballast?

Most of our A19 bulbs, such as the CENTRIC HOME™ Flicker-Free A19 10W LED Bulb, are available in the E27 base which is standard in Europe. 

Further, the power supplies that we have available for use with the LED Flex Strips can accept 100 - 277 V AC input voltage, where 230 V AC appears to be standard in Ireland. 

Further, if the model of ballast found within your fixture is not within our compatible ballast list, we would recommend bypassing the ballast so that the T8 LED Tube Lights use direct wire power. 

If the fixtures contain ballasts that are incompatible, our T8 LED Tube Lights will likely encounter damage which would void the product warranty, as those ballasts were initially intended for adjusting the power supplied to fluorescent tubes in ways that can damage LED hardware. 

Flicker-free Ceiling LED Lights

I want to replace my existing ceiling lights with Flicker Free. They are mounted on the ceiling. What flicker-free replacement light do you have that would be comparable?

While we would normally recommend our dimmable Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential, these items are not flicker-free. As an alternative, you might be interested in our 2700K and 3000K CENTRIC HOME™ Flicker-Free A19 10W LED Bulbs. 

We also offer the CENTRIC HOME™ LED Strip Lights for Home & Residential, which are often installed on cornices or ceiling lines for illuminating residential spaces. These lights can be powered with an in-wall power supply and controlled using wall dimmers or smart home systems. 

What's the difference between the two full-spectrum avian bulbs you carry?

What is the difference between the two full-spectrum avian bulbs you carry? What fixtures do I use with them? Prefer a bendable floor lamp. 

We can confirm that while the Avian A19 bulb offers flicker-free output, the Avian BR30 bulb is dimmable.

​Beyond this difference, the BR30 bulbs are most commonly used in canned or recessed lighting fixtures that have a narrower beam angle than standard A19 bulbs. Further, both will utilize the same standard socket and will offer full spectrum output with a high CRI of 95+.

While we do not sell fixtures for standard lights, we can confirm that our A19 and BR30 bulbs will fit within the standard E26 base. It might be helpful to know that this E26 base is used in most common light fixtures such as lamps and floor lighting.  

Accurate Bulbs for Still Life

I need to know what lumens to paint by and to illuminate the still life. 5000K? I'm only familiar with Verilux lights.

For installations where color-critical illumination is important, such as artwork creation, we recommend the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000). This product povides full-spectrum output and is D50 calibrated, which is a specification for a light source that approximates warm daylight.

I'm trying to reproduce ''north light'' not warm daylight. Would this bulb do that? You also sell product #4005C.50 and #4005C.30. Any difference?

For lighting that mimics northern light, we generally recommend the 6500K option, as it provides a cooler blue light output than the slightly warmer 5000K color point. In the hopes that it proves to be helpful, we have attached a guide comparing the 5000K and 6500K options for artwork creation purposes. 

Difference Between 5000K and 6500K Bulbs

Regarding the 4005C.50 and 4005C.30, these items are solely differentiated by the color temperature that they output. The 5000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb (PN 4005C.50) will provide a much cooler color temperature than the 3000K CENTRIC HOME™ Flicker-Free A19 10W LED Bulb (PN 4005C.30). Otherwise, the two items will provide the same amount of full-spectrum light.

Red Light Bulb for Sleeping Room

Which bulb will produce true red light for a sleeping room?

For evening light, we generally recommend the SUPERWARM™ 1700K Flicker-Free A19 10W LED Bulb. This product provides rosy red light output and offers flicker-free output. 

Do you have color-critical LED bulbs?

Do you have this type of LED bulb available for downlight fixtures? D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000)

Based on the details provided, we would likely recommend our 5000K NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio. This product utilizes the same 5000K LED technology as our D50 fixtures for color matching and is designed for recessed lighting. 

Which of your products are flicker-free and how they compare on an oscilloscope to the Phillips product?

Can you tell me which of your products are flicker-free, and how they compare on an oscilloscope to this Phillips product: 

Philips LED Dimmable Warm Glow Effect A19

I liked your oscilloscope comparison at this article and I'm wondering how yours and the Phillips one compare. One of my kids is very sensitive to flicker, so I want to try to figure out what's best for him.

While we do not have oscilloscope readings for all of our products, we can confirm that our standard A19 and A21 bulbs feature flicker-free output. 

Though currently out of stock, our 24V CENTRIC SERIES™ Flicker-Free Dimmable Power Supply for LED Strip is also able to provide flicker-free output for 24V LED Strip Light products. 

From our review of the Philips product, they appear to provide flicker-free output as well. That being said, it does not appear that the CRI is listed on the product listing. 

Generally speaking, our LED technology uses red phosphor in order to create a high CRI output of 95+. The larger brands often use the far less expensive yellow phosphor, which typically provides a maximum CRI of about 80. 

As a further note, you can tell from our photometric test reports page that our A19 bulbs have a flicker percentage of 0%, and have a flicker index of 0.00. As such, we would not expect them to provide any flicker while operating. 

That aside, if you would like to try and compare our products, please feel free to take advantage of our 30-day return policy. We will gladly provide prepaid return labels so that items from domestic orders can be returned for a refund. 

We need flicker-free for one of my kids so I'm looking at your CENTRIC HOME Flicker-Free A21 LED bulbs. We're testing them in a 300-square-foot room that has four bulb sockets and no dimmer circuit. Usually with four 60W bulbs we feel like it's a bit dark in the room.

On the other hand, with the Phillips flicker-free product I mentioned below (60W; I believe it's 2700K with no dimmer) my wife says the Phillips bulbs hurt her eyes. I know that's a little vague, but which of your products would you suggest I try first: 2700K or 3000K, and 60W or 100W? 

By room size I'd think 100W, but we don't know what makes the Phillips bulbs hurt my wife's eyes, and she's worried about going brighter if the 60W Phillips bulbs already hurt.) I'm hoping that as an expert you might have a better chance at pinpointing what we need first-try than I would as a non-expert.

Based on my use of the Lumen Estimation Calculator, it appears that a 300 square foot room would be fully illuminated by 3,188 lumens. As each of our A19 lightbulbs outputs 800 lumens, we would likely recommend using four of our 2700K CENTRIC HOME™ Flicker-Free A19 10W LED Bulbs. For reference, 800 lumens is equivalent to a 60-watt incandescent bulb. 

We like to define glare as the contrast between the darkest point in a room and the brightest. If a light source is considerably brighter than the surrounding area and does not use any type of diffusion covering, the light output can feel stark and relatively intense. If that glare is a persistent issue, we recommend utilizing a fixture that has a covering for diffusion, which should hopefully help to reduce the effect.

While we might recommend our 2700K Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential as an alternative given the relatively lower lumen output per bulb (450 lumens vs 800), these products are not flicker-free and as such may not be the best option for your installation. 

LED Bulbs for Avian Lighting

We are a large wildlife rehabilitation organization. We have several large indoor rehab rooms that we house many species from songbirds to doves to raptors. I would like to know if you have tubes vs. bulbs.

We are happy to confirm that we have several avian products available in our catalog, such as the Avian Full Spectrum E26 BR30 LED Bulb for Birds and the Avian Full Spectrum E26 A19 LED Bulb for Birds. 

Though not specifically marketed for avian installations, we also have the 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights available which utilize the same full spectrum high CRI LED technology. 

​While our T8 LED Tube Lights are compatible with some ballasts used within fluorescent fixtures, it might be helpful to know that the ballast bypass process illustrated within the user guide can be used to make any T8 fixture compatible. As an alternative, you may also be interested in our LED Ready T8 Fixtures, which would not require any rewiring for compatibility. 

High TM-30 Rating Bulbs

What bulbs, such as A19, have a high TM-30 rating?

We are currently in the process of preparing TM-30 reports for all of the items in our catalog, which we hope to upload to our website as a resource shortly. 

In the interim, we have attached a set of TM-30-18 reports for each of our standard A19 bulbs, which hopefully prove to be helpful for your purchase planning process. 

Flicker-free and High CRI with Lowest Color Temperature  LED Bulb Products

I am emailing to get some information about your different products. I am looking to find bulbs that are flicker-free with the highest CRI you have available.

I would also like to know what is the lowest color temperature you have available for those 2 features. I'm looking to reduce the bluest light while maintaining the highest CRI and having no flicker. If you could help me with the proper product I'm not sure if your circadian bulbs are flicker-free.

Also, I'd love information on the effectiveness of your flicker-free technology. I'd like to learn because a lot of manufacturers say flicker free but they aren't actually.

Based on the details provided, you may be interested in the SUPERWARM™ 1700K Flicker-Free A19 10W LED Bulb. Though providing rosy warm light, it features full spectrum output and a high CRI of 95+. This product also features blue-free output and an M/P ratio of 0.274 for reduced circadian cycle impact. 

While we also offer the dimmable 2400K Lux24™ Circadian LED Bulb - 2400K 95 CRI E26 A19 LED Filament Bulb, this item is unfortunately not flicker-free. That said, it is dimmable and features the same high CRI of 95+. 

We have shared a select few articles regarding our LED technology below, which we hope prove to be helpful and informative. 

Flicker-Free LED Lighting

Are LED Lights Safe? Are They Harmful to Your Health?

Do high CRI LED lamps have a lower M/P ratio?

Blue Light, Melatonin and Circadian Rhythms

Avian Full Spectrum LED Lighting Fixture Dimension

We are designing an Aviary for a hospital. Can you send me the spec with the dimension for this fixture? Where can we buy this from? Can this light be on a dimmer?

We have attached the product specification sheets for the Avian Full Spectrum E26 BR30 LED Bulb for Birds as well as the Avian Full Spectrum E26 A19 LED Bulb for Birds below, which contain the product measurements. 

Avian Full Spectrum E26 BR30 LED Bulb for Birds

Avian Full Spectrum E26 A19 LED Bulb for Birds

As we do not have retail partnerships domestically or internationally, we can confirm that our products are exclusively sold through the storefront on our website. 

As a final note, while the Avian Full Spectrum E26 BR30 LED Bulb for Birds is compatible with dimmers, the Avian Full Spectrum E26 A19 LED Bulb for Bird is unfortunately not compatible. 

Warm Lightbulb Recommendation for Reading Light

I live in CA. A friend suggested you could help me choose a warm bulb that gives enough light to read by, but would make a golden glow through a custom off-white shade. 

Based on the details provided, we would likely recommend our Lux24™ Circadian LED Bulb - 2400K 95 CRI E26 A19 LED Filament Bulb. This product offers a warm rosy output that is designed specifically to have a very low circadian impact. 

The friend who is helping me redesign my bedroom says this one is the equivalent of a 4k0-watt lightbulb. That would not work for reading light. My aging eyes generally need a 100-watt to read by. Given that info, is there another warm light option you would recommend?

While we do have 100W-equivalent lightbulbs, they, unfortunately, cannot yet ship to California. That being said, we would be happy to share your interest in making those items compatible with California energy requirements with our product team. Hopefully, we can add that feature in the near future. 

As an alternative, the closest match in our catalog would likely be the 2700K 60W-equivalent 2700K CENTRIC HOME™ Flicker-Free A19 10W LED Bulb. The output of this product would be slightly cooler than the aforementioned Lux24™ Circadian LED Bulb, and we hope that this is a better option for you as a reading light.

Do you make any bulbs with no flicker or blue light?

Do you make any bulbs with no flicker or blue light? Do you have a canned ceiling light bulb version of this same bulb? 

We can confirm that we have many flicker-free products in our catalog, including the SUPERWARM™ 1700K Flicker-Free A19 10W LED Bulb. As can be noted from the product’s photometric report, this item outputs a very low blue wavelength energy output and has an M/P ratio of 0.274 for ultra-low circadian impact. 

While we unfortunately do not sell the SUPERWARM™ 1700K product in a BR30 version for recessed lighting, we would be more than happy to share your interest in that format with my product team for future development. Hopefully, we will be able to add that option to our catalog in the future. 

Flicker-free with 800+ lumens Output Lighting

 I am trying to achieve the lighting required on page 4 of the link below. https://trackman.zendesk.com/hc/en-us/article_attachments/4403267887003/Spotlight_Installation_Instructions_4.20__1_.pdf. Can you please recommend which of your lighting would work best? I can use the shop light style or more of a can/flood option. 

Based on our review of the document provided, it appears that a flicker-free option with an output greater than 800 lumens is recommended for your installation. As such, it appears that we have several options that could work well. 

As a primary consideration, while our BR30 bulbs are a great option for recessed lighting, they are unfortunately not flicker-free which may affect the video capture of your installation. 

You may be interested in our NorthLux™ 95 CRI T5 LED Linear Light Fixtures due to the ease of installation, flicker-free output, and high CRI of 95+. These light sources can be conveniently installed using the included brackets and DC power cable, and do not require a dedicated power supply. 

As a secondary recommendation, our NorthLux™ 95 CRI LED Shop Light Fixtures are similar to the linear light fixtures in that they only require a DC connection for power, and offer flicker-free output. As is also true of the linear light fixtures, this product is not designed for wiring to line voltage or use with dimmers. 

If wall dimmers and smart home systems are of benefit for your installation, we would recommend the FilmGrade™ WHITE LED Strip Lights, which are designed with video capture in mind. As this item is available in both the 12V and 24V versions, we strongly recommend selecting a power supply of a matching voltage. 

Do you have an A19 95 CRI full-spectrum dimmable 75 to 100-watt equivalent LED bulb?

I need A19 95 CRI full spectrum dimmable 75 to 100-watt equivalent LED bulbs. Do you make any? 

While they are not dimmable, the closest match in our catalog appears to be our newly launched 100W-equivalent LED A21 BULBS. These products provide 1600 lumens per bulb, offer a high CRI of 95+, and have slightly larger dimensions than a standard A19 bulb. 

Compatible Light Fixtures for A19 LED Bulbs

I have just bought 2 bulbs: NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio. I want to install them to a ceiling fixture but not lose the CRI and 6500K. Do you have a list of suitable fixtures? Or any tips for how to choose fixtures to get the best out of the bulbs I've just purchased? 

These lightbulbs utilize the E26 base, which is the common standard socket for lightbulb fixtures in North America. 

So long as the fixture is connected to an E26 base fixture and utilizes standard North American line voltage, the product should provide the optimal output of CRI as well as an accurate color temperature. 

That being said, please note that these LED lightbulbs require a moderate amount of airflow for heat dissipation. As such, we recommend utilizing a light fixture that is not entirely enclosed, so that the heat generated during operation can dissipate. 

Do these lights still work optimally from INSIDE a light fixture? 

For example this kind: Progress Lighting P3925-09 Close-to-Ceiling, Nickel https://amazon.com/dp/B004K5CLBW/

I hear you about ventilation - this may not be ideal for that. But what about the white translucent covering and how much of the light from the bulbs it will impact? 

What kind of light fixture will allow the bulbs to give optimal light while not shining in the eyes? I want to install them on my ceiling fixture. 

As our standard A19 lightbulbs are not designed for enclosed fixtures, we would not recommend pairing them with the Progress Lighting P3925-09 fixture. Further, we do not have any specific fixture manufacturers or models that we could recommend, and we do sincerely apologize for any impact this may have on your purchasing process. 

Unfortunately, we do not have any information regarding the transmission levels of the materials used in the referenced fixture. For accurate transmission data, we recommend reaching out to the hardware manufacturer directly as they likely have information available regarding the average transmission levels of light sources placed within them. 

As a baseline for comparison, it might be helpful to know that the clear polycarbonate material used in our LED Shop Light Fixtures is fully transparent, yet reduces the overall transmission of the light source by roughly ~10%. As such, we would suspect that an opaque enclosure would block the transmission even further. 

As an alternative option to our standard A19 bulbs, we would likely recommend our 2700K or 3000K Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential, which are suitable for enclosed fixtures as well as damp installation areas such as bathrooms. 

High CRI Bulbs for Outfitting House Lighting

I will need a whole bunch of good-quality bulbs. Rather than me poking through your online ordering system and hoping to pick the best options. Can you figure out suitable part numbers with a good 90+ CRI?

Based on our review, it appears that we have two products that directly match the details provided within the lighting table. We have attached links to each product below, in the hopes that it proves to be helpful.

While our A21 lightbulbs are 100W equivalent products that may also be of interest, please note that this standard has slightly larger dimensions than the more common A19 lightbulb. 

4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb 

4000K Full Spectrum E26 BR30 LED Bulb

4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A21 15W LED Bulb

High CRI >90 LED Lights with 6000K-7000K Color Temperature

Do you have an LED replacement for this: Item# F15T8VLX Verilux 15 Watt 18" T8 Fluorescent 6280K 95 CRI Medium Bipin (G13) Base Happy Light/Full Spectrum Tube

Unfortunately, we do not stock lighting products produced by other companies in our catalog. Further, while we offer T8 LED Tube Lights in the 48” length, we, unfortunately, do not have any products matching the details provided in your email. We do sincerely apologize for any impact this may have on your purchase planning.

What products do you have that have a color temperature in the 6000-7000K range and a CRI > 90 that can be put in a somewhat portable light fixture?

Based on the details provided, we would likely recommend either the 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb or the 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A21 15W LED Bulb. 

For a portable light source that contains integrated lighting, you may also be interested in our 6500K NorthLux™ 95 CRI T5 LED Linear Light Fixtures, which feature a high CRI of 95+ and can be daisy-chained to power larger installations. 

What does a 6% flicker rate mean?

I have a 4 lights rail fixture, currently running on 75W E27 BR reflectors. I'm looking for a flicker-free alternative. If I got it right, E26 bulbs should work, though not a perfect fit. As far as I understand, your only option is the 6% flicker bulb. What does 6% mean? that when it "flickers", it is only 6% less than full power? How is it in comparison to indecent flicker? 

While the measurements between the E26 and E27 are very similar, we find that the two standards are not always compatible. We have attached a link to a blog post on the topic below, in the hopes that it proves to be helpful for your purchase planning process. 

E26 vs E27 Bulbs - Interchangeable? Not Necessarily!

Generally speaking, a 6% flicker rate means that there will be a 6% relative difference in brightness between the maximum and minimum brightness output by the light source during a flicker cycle. The lower the relative difference, the less noticeable flicker usually is. 

Compared to our flicker-free LED lights (such as the CENTRIC HOME™ Flicker-Free A19 10W LED Bulb) which offer a 0% flicker rate, traditional incandescent light sources typically have a flicker rate of 15%. 

I know your article about e26/e27, but I still don't understand what might happen. On this page, you wrote that you "recommend exercising caution if used with E27 fixtures." Does it mean that if the bulb work during the day, and not 24/7, it should be fine? And when will you have E27 versions of these?

When E26 and E27 bulbs and fixtures are used interchangeably, the measurement differences in the base may cause arcing to occur at the gap between the electrical connection points. This arcing may cause hazardous electrical hazards to occur, which may damage the products and void the warranty. This is the primary reason why we recommend selecting a bulb that matches the socket used by the fixture. 

Can I use your lightbulbs in any light fixture that has a glass cover?

CENTRIC HOME™ Flicker-Free A19 10W LED: I want to use your bulbs in my ceiling-mounted light fixtures. They all have glass covers and are what I would consider being "enclosed", but I don't understand why your bulbs would not work in them. Am I misunderstanding your use of "enclosed" or can I really not use your lightbulbs in any light fixture that has a glass cover? 

As our standard A19 LED lightbulbs contain hardware and circuitry that traditional incandescent fixtures do not, there are heat dissipation requirements that we consider during operation. If the internal components are unable to disperse heat when installed within a fully enclosed fixture, the heat will eventually build up within the product and cause performance issues. 

As such, we recommend that they are used exclusively in fixtures that have at least a moderate amount of airflow, such as open-ended wall sconces or traditional open lamp fixtures. 

As an alternative, you may also be interested in our Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential, which are suitable for damp locations while offering the same high CRI of 95+ as our standard bulbs. 

Flicker-free Bulb Task Light for Art and Animation

Do you have a recommendation for a flicker-free small bulb for an art task light? Would the SuperWarm bulb be helpful to someone who gets migraines from LED?

While not specifically marketed for migraine reduction, we can anecdotally vouch for the benefits that the SUPERWARM™ 1700K Flicker-Free A19 10W LED Bulb offers as evening illumination without causing eye strain. 

If you would like to try this product, please feel free to take advantage of our 30-day return policy. 

Do you have 220 volts bulbs?

I wanted to ask you if I can use these bulbs my electricity is 220 volts. Do you sell 220 volts bulbs?

We can confirm that many of our lightbulbs, including the CENTRIC HOME™ Flicker-Free A19 10W LED Bulbs, are compatible with global input voltage (AC90-240V/50-60Hz). 

As a further note, these lightbulbs are also available in the E27 base which is standard for Europe as well as the E26 base, which is standard for North America. 

LED Lighting for Birds

I was hoping to order LED lights for birds that are not individual light bulbs but either strips or tube lights. Do you have anything like that for birds? 

While not specifically marketed for birds, we are happy to confirm that the same LED technology found within our avian A19 and BR30 lightbulbs can also be found in our T8 LED Tube Lights and LED Strip Light products. 

As such, you may be interested in our 4000K and 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights, which are designed to be compatible with our newly launched LED Ready T8 Fixtures. 

For an LED Strip Light option, we might recommend either the 4000K CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail or the 6500K FilmGrade™ WHITE LED Strip Lights in 12V or 24V. These lights can be mounted within channels, paired with in-wall dimmers, and powered with DC power supplies or in-wall power supplies

In-Home LED Light to Illuminate a Painting

I recently purchased LED tube lights for my art studio. Northlux 95 CRI T8 LED tubes. A collector of mine wants to purchase a similar light for her home to replicate the lighting I used in the studio. Can you recommend a LED bulb that is similar to the tube light above?

Based on the details provided, there are a few options that we might recommend depending on the ideal fixture being utilized. 

Our primary recommendations would be the 5000K NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio for standard fixtures or the 5000K NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio for canned recessed lighting. 

We also recently launched the 5000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A21 15W LED Bulbs, which can provide double the lumen output of our standard A19 bulbs (1600 vs 800). Please note that these A21 lightbulbs have slightly larger dimensions than the A19 lightbulbs. 

If a dedicated fixture for illuminating artwork is alternatively preferred, you may be interested in our 5000K NorthLux™ 95 CRI T5 LED Linear Light Fixtures. These fixtures contain integrated light sources and power supplies, can be easily installed, and only require a DC plug for power. The primary considerations for this option are that it cannot be paired with wall dimmers and features an on-device power switch. 

Do you have something that would simulate a candlelight or fireside light?

I understand that you have a series of bulbs to simulate daylight and that these are good for the day. Do you have anything that would simulate candlelight or fireside light, that would be appropriate for nighttime without the "keep awake" wavelengths?

Based on the details provided, we would likely recommend our newly-launched SUPERWARM™ 1700K Flicker-Free A19 10W LED Bulb. We can anecdotally vouch for these products, which are able to provide a very warm output that is helpful for evening illumination without being disruptive to sleep patterns. 

Do you have a high CRI E26 base LED bulb for a three-way lamp?

Do you have a high CRI LED bulb with an E26 base that will work and not flicker in a three-way lamp? Preference would be for around 3000K and 450 lumens. 

While we have not performed internal testing using our products with three-stage fixtures, some of our customers have let us know that our A19 bulbs function as expected when used within such products. 

While our standard A19 bulbs have an output of 800 lumens, you may alternatively be interested in our 450-lumen Lux24™ Circadian LED Bulb. We have anecdotally found that this low-output lightbulb compliments residential installations quite nicely, though the output is not flicker-free.

For another alternative that is flicker-free, we would recommend our 600-lumen SUPERWARM™ 1700K Flicker-Free A19 10W LED Bulb. 

If you would like to directly compare these options, please feel free to take advantage of our 30-day return policy, where we will provide prepaid return labels for any unneeded items. 

Lighting Recommendation for Indoor Photography

Would you be able to help me choose lighting to use in my condo that would help me take better photos for my cosplays & other social media images? 

If you have any details regarding the preferred fixtures to be used for the lighting, please let us know and we would be happy to provide a few specific product recommendations for you. 

In the interim, it might be helpful to know that our line of FilmGrade products are designed with film and photography capture in mind. These products feature full-spectrum output, as well as a CRI of 95+, which are both very helpful for ensuring color accuracy. 

​For example, our FilmGrade™ Flicker-Free A19 LED Bulb and FilmGrade™ WHITE LED Strip Lights are available in the color temperatures most often recommended for video and photo capture.

Do you have 400 lumens flicker-free bulbs?

I found 800 lumens far too bright. I am wondering if you have a flicker-free LED bulb that is ~400 lumens. If not, that would be a great addition. 

Based on the details provided, you might be interested in our 600-lumen SUPERWARM™ 1700K Flicker-Free A19 10W LED Bulbs, or our 450-lumen 2400K Lux24™ Circadian LED Bulbs. 

These products are designed for reduced circadian impact, and we can anecdotally vouch for their benefit as a low-light output product. 

Lighting Recommendation for Single Car Garage Space

I am in the process of converting a single-car garage into a space where I will have a single car on display in a relaxed and "man cave" sort of setup. I have two objectives in lighting the space (dimensionally the space is 279"x197" and the ceiling is 111" high) 1) The car is the star in this space. It is red with a black interior. 2) I have some artwork on one wall in the garage I would like to light independently. My leaning is to have dimmers on both circuits. This is not a workspace or a hospital ward; I want to avoid a super bright/cold/antiseptic feel. What it will be is a place to relax with a little music, my wife, our car, and a cold beer. In what direction would you steer me? 

By using my Lumen Estimation Calculator in the interim, it appears that the space would be evenly illuminated by 8,265 lumens. 

Based on the details provided, I might recommend utilizing ~19 feet of the 2700K or 3000K CENTRIC HOME™ LED Strip Lights for Home & Residential for a warmer installation. 

These lights can be installed within the ceiling cornices of the space within our flat or cornered aluminum channels, and controlled using in-wall power supplies and wall dimmers. 

While we also have the LED Shop Light Fixtures available, these products are not available in the warmer color temperatures that you mentioned a preference for. 

If you would like to test which color temperature works best for your garage, we might recommend purchasing a few of our A19 lightbulb options to ensure that they provide the right illumination. 

If any of the bulbs wind up being unneeded, simply let us know and we will gladly provide you with a prepaid return label for their return. 

High CRI 6000K Daylight Bulb

I'm looking for a lightbulb that is a quiet, high CRI daylight bulb that just plugs into a normal household socket, and is 6000k. Do you have any recommendations for me? 

Unfortunately, we do not have any 6000K A19 lightbulbs currently available, and we do sincerely apologize for any impact this might have on your purchasing plans. 

If you would like to directly compare the two closest matches in our catalog, those being the 5600K FilmGrade™ Flicker-Free A19 LED Bulb and 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb, please feel free to take advantage of our 30-day return policy. 

High CRI Color Matching LED Lights

I'm an artist in the UK and I frequently need to mix pigments to match a very specific color of an object. I can't afford a Pantone light booth, so I'm looking for a high CRI/spectrum bulb that can be used in an ordinary lamp holder/fixture. 

Based on the details provided, we would recommend either our 5000K or 6500K E26 CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulbs, which can provide full-spectrum output and a high CRI of 95+. 

High CRI Socket Bulb Similar to Tungsten

Please recommend: a) socket bulb most similar to tungsten with highest CRI - I need to replace all of my lightbulbs but do not want to change temperature too much nor get flatter tone light. b) I have a strip light. Can it be installed outdoors (under a roof)? Do you have an outdoor rated power extension, so I can leave the 24v transformer indoors? 

Based on the details provided, we would likely recommend our 3000K CENTRIC HOME™ Flicker-Free A19 10W LED Bulbs, which offers a CRI of 95+ and full spectrum output while being relatively close to the 3200K tungsten color point. 

For your outdoor installation, it might be helpful to know that our LED Strip Lights are not IP-Rated for protection against the elements. As such, any contact that they have with moisture or condensation may cause an electrical hazard and void the product warranty. 

That being said, several other customers in the past have been able to locate third-party insulated channels for use on boats and covered patios. As such, there may be reasonably safe channel options available elsewhere for your installation. 

As a further note, we regrettably do not have any power extensions available in our catalog which are designed for the outdoors, and we do sincerely apologize for any impact this may have on your purchasing plans. 

Compatible Lighting for Recessed Cans for Art Studio

I have a small room I use for an art studio. The room size is 8 by 10. It has 9-foot ceilings and windows on two of the four walls. Installed are four overhead recessed lights for lighting on cloudy dim days and at night. I have 2 problems. One is the incorrect temperature of light, and (2) shadows on my work table from the lights above. Can you recommend bulbs/lamps for my recessed cans that will be best for the art studio and diffuse the light to minimize the shadows? 

First of all, regarding the color temperature, we recommend using either 5000K or 6500K color temperature lamps under our NorthLux brand to ensure that the light color matches the natural light color coming in through your windows. For recessed light fixtures, the BR30 lamps are generally the most popular option.

​We're uncertain if your current lights are for residential use (e.g. 2700K or 3000K), but a daylight-calibrated color temperature of 5000K or higher will ensure that the light appearance will match that of natural daylight.

​Since you mention that you have two windows, we assume that at least one of those would not be north-facing. As such, the 5000K may be a better fit for you, rather than the 6500K. Here is an article that you may find helpful in further refining your options: 

https://www.waveformlighting.com/art-painting/difference-between-5000k-and-6500k-bulbs

Finally, as far as the shadows and light distribution are concerned, unfortunately, the fixed positioning of the ceiling fixtures will limit our ability to address this issue directly. As an alternative, we would recommend supplementing the light from the sides of the studio space as much as possible, as this will help "fill in" any shadow spots that are cast by the overhead ceiling lights.

A simple solution might be to use our A19 lamps in a floor lamp fixture, but many of our customers have used our T5 linear fixtures which offer a more versatile installation option.

Will your A19 LED bulbs be compatible with bowl fixtures?

I am considering using these bulbs “CENTRIC HOME™ Flicker-Free A19 10W LED Bulb 4005C.27” in a semi-flush ceiling fixture with a large bowl, KICHLER 42025NI. In the past, I have had trouble with LED bulbs overheating and putting a plastic smell when I put them and semi-flush ceiling fixtures with bowls. Will this work, or should I avoid it? 

Strictly speaking, our Centric Home A19 lamps would be suitable for use in the fixture you have as it does not appear to be considered a "completely enclosed" fixture.

​It is a bit difficult to see from the fixture photos, however, whether or not the top of the fixture bowl is open. If there is another cover on the top of the fixture bowl, that may indeed block airflow, making it easier for LED lamps to overheat. Otherwise, we do believe that with sufficient airflow coming in from above, there should not be any serious concerns with respect to overheating.

Human-Centric LED Lighting for Windowless Office

I work in a windowless office and am considering buying lighting from you. Would I buy the long strip bulbs for the ceiling lights? Or would I buy a floor lamp and bulbs? I've been looking at daylight-simulating desk lamps but they look too big for my desk. I have autoimmune and other health issues and already have the diet dialed, hoping to hit from all angles whilst still having to be employed full-time. 

 As far as your question of whether to go with ceiling lights or floor lamps + bulbs, we think both options would work well, and it would ultimately be up to you and your preferences for how and where to install the lights.

Starting with the floor lamp + bulb option, we think this would be the easiest and simplest setup, which wouldn't require any electrical work. Our A19 and A21 lamps are classic screw-in bulbs, so all you would need to do is purchase the floor lamp fixture of your choice and then install our lamps. If your office space is rented, the floor lamp would be portable and you would be able to take the lamp setup with you to any future location as well.

Ceiling lights will be a bit more complicated, as you will need to do some electrical work to get the fixtures wired up. One method would be to purchase our T8 lamps and install them in our T8 fixture. The advantage here would be that the light fixture will be ceiling-mounted, so it won't take up any floor space at all. Additionally, if the fixture is positioned above your workspace, this may allow you to have more direct and evenly distributed lighting (as opposed to a floor lamp in just one corner of the room).

Another option that might be a compromise between the two would be our T5 linear fixtures. These fixtures can be screw-mounted or magnet-mounted onto a variety of surfaces. This might give you both the flexibility of a semi-permanent installation while keeping the fixtures away from the floor.

All of these options offer flicker-free light output and provide full spectrum light, so they should all be a great fit for your needs; as mentioned it will ultimately come down to your personal preferences as far as installation method and location are concerned.

What is the difference between GE Reveal and your products?

I just bought a new house and will be upgrading the lights there. I'm a big GE bulb fan but recently ran into your site. Can you explain the difference between what more you provide vs GE reveal and refreshing series of lights?

By our review of the GE Reveal and Refresh lights, they appear to vary in size and features, though the voltage requirements and lumen output of these items appear to be comparable to our standard A19 lightbulbs. That being said, it appears that some of these GE products are dimmable, whereas only our filament A19 bulbs and BR30 bulbs are compatible with dimmers. 

Further, it appears that our LED lights can offer a higher CRI of 95+, whereas the GE products provide a CRI of 90. The higher CRI can be very beneficial for installations such as artwork studios, galleries, and video capture where robust color-accurate illumination is required. 

As our products are designed to be human-centric, they are created to provide full-spectrum, high-quality output that provides a high CRI to combat eye fatigue while ensuring color accuracy. Unfortunately, we have not been able to locate the full photometric reports for the GE products, which we would like to use to provide you with a comparison of the spectrum output. 

In lieu of that, we have attached a link to our full set of photometric test reports for our full spectrum lights in the hope that it proves to be useful for your product comparison. 

Can you also tell me how your light bulbs compare to the product below? It appears to have a higher CRI and R9 value. 

https://www.gelighting.com/sun-filled-led

The GE Sun-Filled LED product appears to be a new product with what appears to be an improved spectrum intended to better approximate natural daylight. In this regard, the color performance appears similar to our A19 and BR30 products (both of our products achieve 95 CRI and 80+ R9).

Unfortunately, the GE Lighting website does not provide additional information about the extended CRI values, chromaticity, or flicker performance, so we are unable to make any definitive comparisons beyond the general CRI values that their website indicates.

We appreciate your inquiry and will definitely see if we can find more information or even perform internal testing on the GE Sun-Filled product soon!

We would perhaps recommend purchasing both products to test and compare as we can offer a 30-day free return window for all of our products. (Hopefully, GE Lighting's authorized retailers offer a similar returns program, allowing you to perform these tests).

LED Lighting Recommendation for Winter-time Mood

Which of your products do you recommend for lifting people's mood during the winter time? I would guess it's one of your "Centric Daylight" products. Which color temperature is most popular for this use? 

For human-centric lighting, the most important qualities to consider are flicker-free operation, full-spectrum output, and a high CRI. These features in conjunction create lighting environments that cause less eye fatigue while providing a superior quality of illumination. 

To find which color temperatures are right for your installation, we would recommend reviewing this link. If your installation is residential, we would likely recommend the 2700K or 3000K CENTRIC HOME™ Flicker-Free A19 10W LED Bulb, as those are the most common color points for homes. This product, as is true with any color temperatures available in our A19 products, will feature the aforementioned high-quality output. 

Does a 10-watt LED bulb replace a 60-watt bulb?

Under your Flicker Free Products, the first light bulb shown has 95 CRI and a 60-watt replacement. Then it shows the price as $18.00 and then states Centric Daylight Full Spectrum Flicker Free A19 10W LED Bulb

Does that mean that your $18 LED bulb is 10W and is replacing a former 60-watt bulb? So if my husband likes 60-watt bulbs we would order a 10W LED Bulb? What is meant by Filmgrade? Is that a brand name?

We can confirm that our CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb is designed to have an equivalent level of light output as a traditional incandescent 60W bulb. 

We can also confirm that the FilmGrade and NorthLux names are branded lines of products in our catalog which are marketed for different purposes, such as video capture, artwork creation, and studio installations. 

Does one have to use the whole 16 feet of these FIlmGrade LED Strip Lights in one place?

Our FilmGrade LED strip lights can be cut to length, so the single reel can certainly be used in multiple locations. Below are some layout diagrams which may help visualize the installation:

https://www.waveformlighting.com/layoutmaps/3002_3C

https://www.waveformlighting.com/layoutmaps/3002_3E

So each smaller strip needs its own power cord?

Each shorter section will need to be connected to its own power supply unit (12 / 24 volt) which would then feed power to the LED strip segment. See below for a diagram showing how to cut sections would connect to a power supply unit:

https://www.waveformlighting.com/layoutmaps/3002_2C

Will the BR30 LED Bulbs work outside the US?

I'm interested in "NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio" lights and I'd like to know if they would work in Israel. Electricity in Israel is 230 Volts, alternating at 50 cycles per second.

Unfortunately, the NorthLux™ 95 CRI BR30 LED Bulbs for Artwork & Studio are not designed for global input voltage, and we do sincerely apologize for any impact this may have on your purchasing plans. 

As a primary alternative, you may be interested in the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product. These A19 bulbs are designed to be compatible with global voltage standards (90-240 V AC, 50-60 Hz) while offering a high CRI of 5+ and flicker-free output. 

Though we have not been able to identify the standard lamp socket base common to Israel, it might be helpful to know that this line of products is available in both the E26 and E27 base standards. 

Lighting Option for Basement Painting Studio

I am trying to improve my basement painting studio lighting, and your brand came highly recommended. I am leaning towards 5000K and would like something flicker-free, ideally. I am trying to decide if I should get the Northlux bulbs or the Centric Daylight full spectrum bulbs for my inset ceiling cans. Can you explain the difference between the two for me? I also need to get some supplementary lights as tubes or something similar that don’t drop too far down from the ceiling.

We can confirm that the CENTRIC DAYLIGHT and NorthLux A19 bulbs are identical products that are provided with unique landing pages for marketing purposes, as can be noted by the shared part numbers. As such, identical output can be expected from each product, and we do sincerely apologize for any confusion this may have caused. 

For the ceiling tube lights, you may be interested in our NorthLux™ 95 CRI T8 LED Tube for Art & Studio, which is designed to be compatible with our LED Ready T8 Fixtures. 

As a further option, the NorthLux™ 95 CRI T5 LED Linear Light Fixtures are integrated lighting units that can be easily installed on different surfaces for convenient lighting adjustment. 

Difference between Centric Home and FilmGrade 3000K

Are the Centric Home 3000K and FilmGrade 3000K bulbs the same? because on the photometric page, the test report is the same for both bulbs, even if the time stamp is the same. If they are different, what is the difference? 

We can confirm that the 3000K FilmGrade™ Flicker-Free A19 LED Bulb and 3000K CENTRIC HOME™ Flicker-Free A19 10W LED Bulb are identical products that are provided with unique landing pages for marketing purposes. This can be noted by the shared part number of PN4005C.30. 

What does the "C" mean in the NorthLux and Centric A19 bulbs?

In the article, I see the following difference in the part number PN 4005.65: CENTRIC DAYLIGHT™ 6500K PN 4005.D65: NorthLux™ 6500K But when I add them to the cart they are both added as 4005C.65. Can you clarify? What does the C mean? 

While these two products previously utilized different product numbers, each recently received hardware updates to make them compliant with California energy standards (Where the 'C' notes California compliance). 

After that point, the two products began to utilize the same product number (PN4005C.65), as the hardware and output of each are identical. We have kept the distinct product pages as-is, as having unique landing pages is helpful for marketing purposes. We do apologize for any confusion these pages may have caused. 

Based on the page, one is supposed to be calibrated on ANSI 6500K while the other is calibrated at D65, which are two different spectrums. What is the new product “C” calibrated on?

While these products were previously calibrated differently, we can confirm that all of our 6500K ‘C’ products are now calibrated to D65 rather than ANSI 6500K. 

Why your LED bulbs cannot be used in a closed fixture?

Can you explain why your bulbs cannot be used in a closed fixture? I understand that they cannot be used with a dimmer, but what about non-dimmable closed fixtures? 

Our CENTRIC HOME™ Flicker-Free A19 10W LED Bulbs contain hardware that is heat-sensitive and requires heat dissipation for safe operation. When these lights are used within open fixtures such as sconces or traditional lamps, the heat is easily able to dissipate through moderate airflow. 

​As an alternative, you may be interested in our A19 LED Filament Bulbs, which are suitable for fully enclosed fixtures without concern for component overheating. These lights are available in the most common color temperatures for residential installations (2400K, 2700K, and 3000K).

High CRI Flicker-free LED Bulbs for Color Matching and Painting

I’m looking for high CRI bulbs for my art studio, and I’m wondering which of your bulbs would be the highest in CRI value for color matching and painting? Also, you have flicker-free bulbs. Is that referring to the actual bulbs flickering or the frequency they work on that stop flickering when filming in slower frames per second?

For art studios, we usually recommend the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio, which is available in the most common color temperature for artwork (5000K and 6500K). As our line of A19 and A21 bulbs utilize the same internal technology, they will all feature the same high CRI of 95+. 

Though not a lightbulb, you may also be interested in our ABSOLUTE SERIES™ LED Flexible Strip. This product features a CRI of 99, making the output virtually indistinguishable from natural daylight. 

Generally speaking, the flicker rate of the LED lightbulbs is calculated by measuring the relative difference in brightness between the maximum and minimum brightness exhibited during a flicker cycle. 

Our flicker-free lightbulbs output light that is constant and uninterrupted, meaning that the fluctuations of brightness are extremely minute (less than 1%). For installations where they are used to illuminate video capture, the lights fluctuate fast enough that there would not be any visible flicker. 

LED Lights for Small Home Studio

I'm a serious amateur photographer with an interest in photographing art (primarily oil paintings) in art galleries in the US and Europe. It is important to me that my images, which are both printed and used in PowerPoint slide presentations, show the true colors as painted by the artist. I have the requisite tools to calibrate my screens and art-quality printer. However, I am concerned about the lighting in my small home studio. My studio is a second bedroom with a white ceiling and light beige walls. There is a south-facing window with a translucent shade that remains down. All lighting comes from lamps placed strategically so as not to have direct light on my monitors. Each has a tapered (empire-style) white shade that illuminates the ceiling. 

The light at the workstation appears quite uniform, but I do not have the capability to measure this. The light bulbs are standard hardware store LED lamps. 5000K, 2200 to 2400 lumens I have been reading your literature, and it would appear that I am using inappropriate bulbs for my application. I would greatly appreciate your recommendations for A19 bulbs that would be better suited to my needs.

Based on the details provided, we would likely recommend our 5000K NorthLux 95 CRI E26 A19 LED Bulb for Art & Studio. These products are available in the most common color temperatures for photography and artwork creation (5000K and 6500K) and offer flicker-free output with a high CRI of 95+.

That being said, it does appear that they are only able to offer 800 lumens compared to the 2200 to 2400 lumens of the existing lightbulbs. As such, in the event that they fit your fixtures, we might recommend the 5000K CENTRIC DAYLIGHT Full Spectrum Flicker-Free A21 15W LED Bulb.

​The A21 bulb has slightly larger dimensions than the aforementioned A19 bulbs, though it is also able to provide the same high CRI of 95+ along with doubled output at 1600 lumens.

In the event that you would like to directly compare these options in your home studio, please feel free to take advantage of our 30-day return policy if any of the items wind up being unneeded. We will gladly provide prepaid return labels upon request.

Are the BR30 Bulbs compatible with the Australian 230V AC?

Do you ship to Australia and are these bulbs compatible with Australian 230V AC?

We are happy to confirm that we can ship orders internationally to Australia.

Unfortunately, the NorthLux™ 95 CRI BR30 LED Bulbs for Artwork & Studio are not designed to be compatible with global voltage standards, and we do sincerely apologize for any impact this may have on your purchase planning. 

As an alternative, you may be interested in our NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio, which is compatible with 90-240 V AC and offers the same high-quality light output as the BR30 bulb. 

Light Recommendation for Office and Residential Lighting

Deciding between the 2700K or 3000K Centric Home and 4000K, 5000K, or 6500K Centric Daylight.

Do Lux24™ Circadian and A19 LED Filament Bulb fit in a regular socket at home? I have three ceiling fans/ lights that need a smaller base. Do any of these fit in the smaller base?

I need good lighting in an office, and a bathroom with a four-bulb fixture. I think I want a softer feeling for my eyes but also to see clearly. However, they can be so bright it is too bright. Not sure about the 2700K or 3000K centric home - It will be warmer, but will it be that healthy full-spectrum? Will it be bright enough to help me see everything and think?

Would the Lux24™ Circadian LED Bulb - 2400K works in an office? 

My bedroom has those Full-spectrum solutions/ blue Max brand candelabra lights in the ceiling fan. Most nights I avoid even turning on the light in the bedroom as I get into bed- because they are so bright. I do not have a bedside lamp. If those bulbs would fit in the ceiling fan- that takes the smaller bulbs, I would- but these don't fit into the smaller base - right?

The A19 bulbs referenced utilize the standard E26 base, which is a very common standard for home fixtures, such as lamps and recessed lighting.

The base that you are likely referring to is known as an ‘E12 candelabra base’, which we currently do not have available in our catalog. 

For offices, we recommend the 4000K color temperature. You might specifically be interested in the 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb for your work area. This color temperature is cooler than the warmer 2700K options, though they will both offer full spectrum output. 

For bathroom fixtures, we would likely recommend the 3000K Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential, which is designed to be suitable for damp locations and can offer full-spectrum light output. 

As previously noted, the 4000K color temperature is the most common option for offices and workspaces. The 2400K is more commonly used for evening light, rather than productivity due to the very ‘warm color' output. As such, we would likely recommend the aforementioned 4000K CENTRIC DAYLIGHT™ A19 lightbulb. 

We can confirm that the 2400K Lux24 A19 lights would not be compatible with the E12 candelabra base fixture. 

Do you have a 2D-21W-6600K bulb for photographing jewelry?

I am trying to locate this part number 2D-21W-6600K bulb I need it for a photo box for photographing jewelry. I did order some bulbs that were the same size from Amazon but they showed up yellow when I put them in my box. I must have an absolute white color for jewelry is this something that you can help me with? Do you sell them or can you tell me where I might be able to go to get them?

While we do not have any products that utilize that product number, we are happy to confirm that we have many 6500K products designed for photography and color accuracy. 

For your photo box, we would likely recommend our 6500K Ultra High 95 CRI 6500K E26 A19 LED Bulb for Jewelry & Display, which offers flicker-free output and a high CRI of 95+. 

Can I use the A19 LED Bulb within three-way fixtures?

I found you by searching for "high CRI" and your product line looks promising. I plan to order several different products, but before doing need to answer a question about one in particular; I used the website search to look for "3-way" but didn't find any results. Specifically this product, 4005C.50, says it's not dimmable, but will it be okay if I use it in a 3-way torchier lamp that is open at the top? I don't know if 3-way is considered dimmable or not, or how that works. 

We do not have any testing data available regarding the compatibility of our CENTRIC HOME™ Flicker-Free A19 10W LED Bulbs (PN4005C.50) when used within three-way fixtures, and we do apologize for any impact this may have on your purchase planning. 

If you would like to try the product with your fixture, please feel free to take advantage of our 30-day return policy. If they do not operate as hoped, please let us know and we will gladly provide you with a prepaid return label. 

High CRI Dimmable Candelabra Bulbs

I am trying to find dimmable, high CRI candelabra bulbs but am having a really hard time finding them. Do you have them and I am missing them do they just not exist with dimming capability? If not, I could purchase an adapter to go from a E12 to the normal A19 base, but is there any issues doing that for light performance? Finally, on the A19 fixture, I was hoping for a dimmable, 60W equivalent 3000K bulb, what light would you recommend?

We currently do not sell E12 candelabra bulbs at the moment, and we do apologize for any impact this has on your purchase planning. 

While we have not attempted to use A19 bulbs with an E12 base fixture through an adapter, we would recommend checking the voltage of the fixture to ensure compatibility. These details are often listed on stickers applied to the base of the fixture.

Given the details provided, we would recommend our Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential as a dimmable A19 option in 3000K. That said, it might be helpful to know that this product is a 40W equivalent bulb, rather than a 60W equivalent. 

High CRI E27 flicker-free LED Bulb

I am looking for a bulb lamp E27, 220V (Europe) with a high CRI value and flicker-free. 3000K or adjustable between 2700-4000K. The light intensity must be dimmable. I prefer a filament bulb. If not possible, an ordinary bulb can also be used. Do you have something to offer, please? I saw on your website article: 4007.30, FilmGrade Flicker-Free A19 Led Bulb. But this is apparently not dimmable in light intensity. Do you have an alternative?

Based on the details provided, the closest match in our catalog would be the 3000K E27 FilmGrade™ Flicker-Free A19 LED Bulb referenced, though we can confirm that this product is not dimmable nor able to offer dim-to-warm adjustable output. 

While we do offer the Ultra High 95 CRI A19 5W LED Filament Bulbs, these products are not designed for E27 bases and are not compatible with global voltage standards. We apologize!

E14 and E27 Flicker-free LED Lights

I have a migraine and need flicker-free LED light bulbs (25 W and 60 W (I do not know how much that is in LED), and I need them in E14 and E27). I also need flicker-free fluorescent lamps (LED). I need a yellow light (not white or white-blue). Which of your products do you think is the best for me? I live in Sweden, how much is the shipping for just a few of your products for me to test before I buy more?

While we do not have E14 bulbs, you may alternatively be interested in our 60W-equivalent (800 lumens) E27 CENTRIC HOME™ Flicker-Free A19 10W LED Bulbs and CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulbs. These products are compatible with global voltage standards, provide flicker-free light output, and offer a high CRI of 95+. ​

While our T8 LED Tube Lights and LED Ready T8 Fixtures are not compatible with global voltage, we might alternatively recommend our CENTRIC DAYLIGHT™ 95 CRI T5 LED Linear Light Fixtures. These fixtures are compatible with 120 – 277V AC 50-60 Hz, but will likely need a wall plug adapter for use in Sweden. 

Does your FilmGrade™ Flicker-Free A19 LED Bulb compatible with an outlet lamp dimmer?

I'm wondering if the FilmGrade™ Flicker-Free A19 LED Bulb is compatible with this outlet lamp dimmer.

Unfortunately, we can confirm that the FilmGrade™ Flicker-Free A19 LED Bulbs are not compatible with the referenced dimmer or other dimmer products. We do apologize for any impact this may have on your purchasing plans. 

As an alternative option, you may be interested in our Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential products, which can be paired with dimmers. 

I guess I don’t understand a 40-watt bulb. Most fixtures take one or two 60-watt bulbs. Won’t this be really low light? 

And aren’t the Edison bulbs more pretty than useful? I imagine that kind of clear glass and filament bulb won’t be as bright as a frosted bulb.

We can confirm that the A19 filament bulbs do not have a high lumen output compared to our other bulbs (450 vs 800+ lumens), and are most often used for areas where low, warm light is preferable. ​

Pure White LED Bulb for Residential Lighting

I found that most residential LED bulbs look somewhat orange in color. Especially at night. I find them hard to read. I want a pure white bulb but find them difficult to attain. What do you recommend, please? I would also like a high-wattage bulb 150-watt equivalent.

For a neutral white color temperature, we usually recommend the 4000K option. If it proves to be helpful, we have attached a color temperature guide from our website below. 

Which LED Light Color Temperature Should I Choose?

While we do not have a 150W equivalent currently available, you may alternatively be interested in our new 100W-equivalent 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A21 15W LED Bulb. 

Can you please explain what 4000K, 5000K, and 6500K means? I appreciate your willingness to help me understand LED technology, which is somewhat difficult to understand.

Generally speaking, color temperatures (4000K, 5000K, 6500K) are measurements for the color of light being produced by a light source, measured in degrees Kelvin. 

​For example, the ‘warm orange’ tones that you referenced earlier were likely the output of ‘warm' color temperature lightbulbs, such as 2700K or 3000K. These warmer color temperatures are usually recommended for homes and residential properties.

Comparatively, the 'cool white' lights that you have likely seen in factories, large stores such as Costco, or hospitals are usually 5000K or 6500K. Offices usually use the more 'neutral' 4000K color temperature. 

In the hopes that it proves to be helpful, we have attached an image from a blog post on our website below, which displays the visible difference that the most common color temperatures would have on the same kitchen installation. As you can tell from the image, the higher degrees Kelvin, the cooler the light output becomes.

Full Spectrum Lighting that Mimics Natural Sunlight

I am essentially a shut-in right now with limited exposure to natural sunlight due to small windows in my mobile home. I am also sensitive to strobe lights. My pets and I all need the health benefits of natural sunlight. Can you recommend a bulb that I can use throughout my house that will provide a lot of light that will help our bodies, but not risk triggering seizures? 

We are proud to offer many human-centric lightbulb products that offer full-spectrum, flicker-free light which is designed to reduce eye strain.

Based on the details you provided, we would likely recommend our CENTRIC HOME™ Flicker-Free LED Bulbs in A19 or A21 versions, which are available in the 2700K and 3000K color temperatures most commonly used for residential installations. 

Further, it might be helpful to know that the primary difference between the A19 and A21 versions is the light output (800 vs 1600 lumens) and size, where the A21 is slightly larger.

Will the electrical contact of the A19 bulb reach temperatures above 80°C (176°F)?

Will the electrical contact (foot) of the bulb reach temperatures above 80°C (176°F)?

We do not expect the lamp base to reach 176 °F, but we are unable to provide any guarantees here.

​If the bulbs will melt a plastic socket what solutions could you propose for cooling the light?

The best method would be to provide as much airflow as possible. This might of course be challenging when considering the installation itself, but unfortunately, this would be the only realistic way to keep the lamp from getting warmer.

​Does the temperature affect light quality, quantity, and/or color?

Temperature rise does affect the spectrum and light output, but the effects are generally minimal (e.g. CCT within 30-50K, luminous output within 10%).

​Can the bulbs survive temperature differences of 30°F repeating every day? If No please answer the following: a) Why might my lights be raising in temperature? Could it be a result of powering it off of 120v AC wires? b) Will replacing them fix the issue? If so, how can I replace my lights?

As long as the ambient temperatures do not exceed standard indoor room temperatures, repeated thermal cycles should not have any effect on the lamps' longevity.

D65 Illuminant for Color Correcting Lighting

I'd like to purchase an accurate D65 illuminant (6500k?) for color-correcting a custom-built camera with a MacBeth chart. Can you please recommend a kit of hardware to purchase from you to create this lighting?

We offer several D65 color-calibrated products which may be of specific interest to your needs. Below are some recommendations:

All of these options at 6500K are also calibrated to the D65 color point and are excellent options for color matching using digital imaging equipment (D50 is of course another popular option for visual inspection).

​We have a windowless room dedicated to different camera calibrations, used frequently. The A19 and T5 are great options as they seem to be easily removable. For the A19, would something like this be what you recommend for hosting the bulb? What differences should I expect in light output from the A19 and T5?

Our calibration room has never been used for color calibration, so I am also shopping for a white booth/background. Unlikely, but I’m open to suggestions for this too.

In terms of color quality, you would not notice any difference as both are calibrated to the exact same D65 color point, so it ultimately comes down to the lighting installation and how you'd like to configure the lights.

In terms of brightness, the A19 lamps emit 800 lumens, while the T5 linear fixtures 900 lumens and 1800 lumens for the 2-ft and 4-ft versions, respectively. If your illumination target is a longer, more rectangular area, the linear fixtures might be a better way to evenly illuminate the entire surface.

I've reviewed the Amazon link and can confirm that this would be a great lamp fixture for the A19 lamp!

While we aren't able to provide direct support for the lighting booth and background, here's an article from Church Film School which features our products and may have some overlaps with your project and may be helpful: 

https://www.churchfilmschool.com/blog/how-to-set-up-your-office-for-color-grading

Your lamps have been working great, but now I’m looking for something that has a variable temperature. Do you sell anything with a wide range of temperatures?

We, unfortunately, do not have any complete lamp products that offer color temperature control. The closest option we offer is an LED strip component for film and TV studio applications. I've provided the link below:

Can I use the Centric Home A19 bulb in Ceiling Fan Light Kits?

I'm interested in using your centric home flicker free A19 10W bulbs in my new home, including in ceiling fan light kits. I see on the web page that the bulbs are not suitable for enclosed fixtures. Does that mean that these bulbs should only be in non-sealed ceiling fan light kits? Eg - glass "bowl" light kits that don't seal at the top, or shades (separate for each bulb). 

The restriction on our bulbs applies to completely enclosed ceiling fixtures only, and as such, they can safely be used in ceiling fan light fixtures as long as there is at least a partial opening.

Based on your description of the ceiling fan light fixture that you currently have, we do not see any issues with the enclosed fixture limitation.

LED Lights for Daycare Settings in the Subarctic

I am looking for a recommendation for a daycare setting in the subarctic. In the depths of winter, it can be light from 10 am until 2 pm and dark the rest of the time. The children nap after lunch. I would love to hear your thoughts on replacing the bulbs with something healthier for our little ones.

Based on the details provided, we would recommend our 95 CRI products, which are designed to output a high CRI rating to accurately mimic the spectrum of natural daylight. 

We can also confirm that we typically recommend the 2700K and 3000K color temperatures for living areas and residential installations, as they offer warmer light output than those designed for offices or commercial spaces. 

As such, we would likely recommend either our CENTRIC HOME™ Flicker-Free A19 10W LED Bulb or the newly launched CENTRIC HOME™ Flicker-Free A21 15W LED Bulb, which are available in both color point options. 

As both offer a high CRI of 95+, the primary difference can be found in the product measurements, where the A21 is slightly larger, and the lumen output (800 lumens for the A19, and 1600 for the A21).

​Your daycare installation may alternatively benefit from a slightly cooler 4000K color temperature, and you may decide to match the color temperature currently being used. If so, we can confirm that both of the above bulb sizes are available in 4000K. 

Health LED Lighting Fixtures

What products do you have so I can evaluate their application in my remodeling? I have an electrician who can follow up to address specs/tech matters.

Our Full Spectrum E26 BR30 LED Bulbs are a great option for recessed lighting, though they are not flicker-free as our A19 and A21 LED bulbs are. 

While we do not sell integrated recessed light fixtures, you might alternatively be interested in our ceiling-mounted LED-Ready T8 Tube Light Fixtures, which are designed to be compatible with our flicker-free CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights. 

LED Lights Recommendation for Art Studio

Could someone help me decide which light and what Kelvin I should use for my art studio? I have two rooms in my apartment where I do painting and glare on the palette from the windows and from the track lights above is an issue. Will a fluorescent bulb cut down on glare? I use a glass palette and paint mainly in oils that already have a slight sheen. My ceilings are not very high, about 11 feet.

For artwork production, we typically recommend the 5000K and 6500K NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio or the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio. The latter option might be specifically useful for your studio track lighting. 

We have provided a link comparing the color temperature options below, which We do hope proves to be helpful. In short, if the goal is to replicate natural daylight, we suggest the 6500K option. 

Difference Between 5000K and 6500K Bulbs

Do you have a BR30 bulbs in 2700K?

I'd like to purchase the BR30 Bulbs in 2700K. It doesn't look like you offer this product in that color temperature. Could you please advise me of a similar product or if you plan to stock 2700K?

We can confirm that we do not sell the BR30 bulbs in the 2700K color temperature. We apologize!

As alternatives, we might recommend our 2700K CENTRIC HOME™ Flicker-Free A21 15W LED Bulb or the 2700K CENTRIC HOME™ Flicker-Free A19 10W LED Bulb. 

Does your Superwarm A19 bulb emit an amount of ultraviolet output?

I was looking at the ultra-warm bulbs and looked at the spectrograph and it looks like there’s a little bit of output near the UV range of 380nm. I was trying to get light without UV. Previously I bought the Centric bulbs, do you know if this has more or the same amount of output near 380nm?

We are happy to confirm that our SUPERWARM™ 1700K Flicker-Free A19 10W LED Bulb, like the referenced Centric A19 bulbs, does not emit ultraviolet output. 

Can I use your products with 230V and 50Hz inputs?

Do all of your products support 230V and 50Hz? I live in a country where the gride provides ~220-240V, 50Hz. Can I use your products with these inputs?

We can confirm that many of our products, such as the CENTRIC HOME™ Flicker-Free A19 10W LED Bulb, are compatible with global voltage standards (AC90-240V/50-60Hz). That said, we recommend ensuring that the products utilize a compatible base before ordering. 

The voltage compatibility of each product should be listed within the product description as well as within the specification sheets available on each product page.

I decided to upgrade my home setup with 6500K lighting with +90 CRI, so if you could please help me choose the right light bulb or light tube that can fit the voltage and frequency I have, I would be grateful. Additionally, do you sell lighting fixtures for your products? If not can you recommend me a good brand I can purchase it online.

You might be interested in the 6500K NorthLux™ 95 CRI T5 LED Linear Light Fixtures, which are compatible with 120 – 277V AC 50-60 Hz. That said, an adapter for local DC plug standards might be required for your usage. 

As a ceiling-mounted T8 LED Tube Light option, we recently launched the LED Ready T8 Fixtures which are also compatible with our 6500K T8 LED Tube Lights and 120 – 277V AC 50-60 Hz input voltage.

Which bulb would be closest to a GE 60W soft white bulb?

I have been trying to find LED bulbs that do not appear to cast a weird greenish/yellowish tint on our walls. I’ve been trying so many brands with no luck. I seem to be very sensitive to the weird color tones LED seems to have. I’m wondering if you think it is worth a try to order some of your lightbulbs if people like me sensitive to non-incandescent bulbs might have better luck with your bulbs. Anyway, wondering if you have had experience with people noticing a color difference with your bulbs. Do you have a suggestion for which bulb to try that would be closest to a GE 60w soft white bulb? 

Based on our review of the details provided, we would recommend our 60-watt equivalent 2700K or 3000K CENTRIC HOME™ Flicker-Free A19 10W LED Bulbs. These A19 bulbs feature a high CRI of 95, meaning that the output is very similar to that of natural daylight. 

Recommended A19 bulbs for Print Viewing

I am a photographer that does fine art inkjet printing. I work in a color-managed system. My monitor is calibrated and profiled to D65. I am looking for an A19 bulb that will give me the best color for print viewing. I need to be able to have the print next to my monitor to compare the print to the image I see on my monitor and judge my color corrections etc. Which of your products would you recommend? 

Based on the details provided, we would recommend our 6500K NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product. 

For additional color calibration lighting, you may also be interested in our Sidewinder™ LED Flex Strip for D65 Bias Lighting product. 

Natural LED light for Light Hyper-sensitivity

I have neurological vision damage and hyper-sensitivity to light or photophobia. The best light for me is a mix of natural light and a little fluorescent. I was wondering if you could recommend one of your bulb types for this type of condition.

For the reduction of eye strain, we usually recommend our flicker-free, high CRI products, such as the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb. This product is also available in the 4000K color temperature, which is often recommended for office use. 

Flicker-free LED Light in E27 Fitting for Physiotherapy and Yoga Basement Room

I'm looking for basic lighting for a basement room that has been set up as a practice room for physiotherapy and yoga. The light quality is important here because there is no daylight and the physiotherapists spend many hours in this room. Can your lamps be used in a European electricity network of 40Hz and an E27 fitting? The following features are important: - Sphere or bulb shape in retro look with filaments or opal glass. - Light color 3000K or adjustable between 2700-4000K (if flicker free) - CRI of minimum 90. 

Unfortunately, we do not have any products available in our catalog that directly match the details provided in your email. 

The closest matches available would be the E27 CENTRIC HOME™ Flicker-Free A19 10W LED Bulb or E27 CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb, though neither are able to offer adjustable color temperatures.

Lighting Solution for Billiard Table Lighting

I am searching for a lighting solution for my 4x9 billiard table. The glare and eye strain from the lighting we have now are just awful. What options do you recommend?

Based on the details that you provided, you might be interested in our NorthLux™ 95 CRI LED Shop Light Fixture, which is designed to hang from the ceiling using the included chain and hook​.

That being said, the cool 5000K and 6500K color temperatures that the product is available in may not be as warm as you might hope for the installation area. 

I also noticed that you sell two different high CRI bulbs that would fit that fixture. One is the Northlux. The other is the Centrick Daylight. Can you compare and contrast the two for my application?

Some experts in GB studied this and concluded that 5500k was optimal for billiards. I am thinking that swapping out a couple of them for the 6500k might bring me closer to this. Or is my thinking off? You hinted that I may not like the bulbs in a range near 5000K.

Most of the companies in the USA and GB which sell high-end billiard lights are putting parabolic louvers below the lights to further diffuse and reduce glare. And all of them are cheap and use 80 CRI high-lumen bulbs or using a flat panel. And even then, they put the louver below it. I can not find a flat panel light with a high CRI. I do not think the flat panel was made for my application.

While we can confirm that we sell both the Northlux and Centric products, it might be helpful to know that the LED Shop Light fixture utilizes pre-installed LED Strip Lights rather than lightbulbs. We do apologize for any confusion that the product page may have caused. 

If you would like to make direct product comparisons between the two color temperature options, please note that we offer a 30-day return policy for all orders, and are happy to provide prepaid return labels for unneeded products. 

If traditional A19 lightbulbs are instead preferred, you may find value in the 5600K FilmGrade™ Flicker-Free A19 LED Bulb, as this option is the closest in our catalog to the 5500K color point referenced.

Do your E27 light bulbs have a diffusing surface?

Do your E27 light bulbs have a diffusing surface? I get the impression from the picture that this is the case, but I see no mention in the description. May I ask these two more general questions: 1) I heard that the diffusing eats up around 25% of the light (lumens). Is that true ?, 2) If I have the choice between ceiling-flooding and bulbs (with diffusing surface) in plain sight, is one less eye-straining, or is it the same? 

Our A60 E27 light bulbs utilize a diffuser cover to help distribute the light in an omnidirectional manner and further reduce glare. You are correct, however, that the diffuser does reduce the amount of brightness due to transmission losses. We estimate the loss to be between 10-20%.

We generally recommend using lamps with diffusers for all indoor lighting applications, as the bare LED emitters do provide very high intensity and may be uncomfortable when looked at directly.

D50 vs Centric Daylight for Basement Home Office Lighting

Your company appears to be one of the best for high CRI lightbulbs. I am working on a basement-level home office with no natural light. I will be working out of this office most of the time (40+ hours a week). Your D50 5000k bulb initially caught my attention for the high CRI and R9>80. Your Centric Daylight 4000k bulbs are also appealing for a touch warmer tint. Does the Centric Daylight have a lower R9? What would you recommend for a home office? 

Generally speaking, we like to recommend the 4000K color temperature for offices and workspaces. Further, we can confirm that the 4000K Centric Daylight A19 bulb offers an R9 value of 95, whereas the D50 A19 bulb offers an R9 value of 92. 

As such, we would likely recommend the 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb for your basement office. For greater output per bulb (800 vs 1600 lumens), you might also be interested in our newly launched 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A21 15W LED Bulbs. 

Can I install a dimmer control for Avian Full Spectrum A19 LED Bulb?

Can I install programmable dimmer control for Avian Full Spectrum E26 A19 LED Bulb for Birds? Will it affect the function of the light bulb or will it damage the bulb? I would like to simulate the actual slow sunrise and slow sunset patterns for my bird cage. 

Unfortunately, we can confirm that the Avian Full Spectrum E26 A19 LED Bulb is not compatible with dimmers. As such, utilizing the lightbulb with a dimmer could potentially cause performance issues. 

That said, you might also be interested in our dimmable Avian Full Spectrum E26 BR30 LED Bulb for Birds, though we would encourage you to ensure that the input voltage of 120 V AC, 50-60 Hz is compatible with your local voltage standards. 

Choosing Proper Lights for Home Reno Project

I am doing a home reno project that is including renovating two bathrooms and the kitchen. Could you help me figure out which of your products is right for me and let me know product availability? Full-spectrum, flicker-free, low EMF are my desired features for lighting.

Ceiling fixtures: I will have two of these installed (one already is): Sputnik chandelier

For the Sputnik chandelier, we would recommend the dimmable 3000K Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential. The 3000K color temperature is the most common option for kitchens and dining areas. 

Under-cabinet task lighting (four zones): I'm looking for a permanent power supply installation of strip lighting instead of each zone lighting having to take up a wall plug. 

For the under-cabinet kitchen zones, I would recommend the 3000K CENTRIC HOME™ LED Strip Lights for Home & Residential with the Aluminum Channel for LED Flex Strip and TRIAC dimmable power supply. 

Please note that these 12V LED strip light products have a maximum combined length of 16.4 feet, meaning that connected lengths greater than that will experience diminished output.

As such, if the under-cabinet zones are to utilize greater than 16.4 feet of product, we would recommend utilizing a second dedicated reel of LED strip lights paired with a dedicated dimmable power supply. 

As can be noted in the below LayoutMap, multiple power supplies, and LED strip lights can be connected to the same dimmer. Our power supplies are also compatible with smart home dimmers. 

LayoutMaps™ - LED Strip Light Layout 3001-1C

If you would like to provide us with a rough layout of the under-cabinet installation areas, I would be more than happy to provide a recommended parts list and order quantity. 

High hats: My licensed electrician is supplying these. He said he can choose styles that take bulbs instead of LED light covers, but he knows nothing about flicker-free, full-spectrum lighting.

For dimmable lightbulbs that would be compatible with a partially or fully enclosed high-hat fixture, we would recommend the 3000K Ultra High 95 CRI A19 5W LED Filament Bulb. 

Bathrooms: I've gotten this wall fixture for both bathrooms: Maxim Lighting Essentials 4-Light polished chrome bath vanity light.

Based on our review of the fixture, I would recommend the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential, as it is suitable for enclosed fixtures as well as use in damp locations such as bathrooms. We usually recommend 2700K or 3000K for those areas. 

Garage: I currently have a ceiling fixture that uses florescent bulbs. 48". I don't spend a lot of time out there and am not sure I want to spend extra for specialty bulbs. 

For the garage fluorescent fixture, we would recommend our 5000K NorthLux™ 95 CRI T8 LED Tube for Art & Studio. Before purchase, we recommend checking to ensure that if a ballast is utilized within the fixtures, it is compatible with our LED tube lights. If not, these lights can also be installed using a ballast-bypass method. 

As a final note, please feel free to take advantage of our 30-day return policy if items within your purchase aren’t quite the right fit. For the LED strip lights, we are happy to accept them as returns so long as they have not been cut or altered. 

LED Bulb for Desk Lamp Used for Reading

I'm looking for an eye-healthy bulb for desk lamps used for reading and over computer desks. Most important to us is a bulb good for the eyes in this usage. 

We have attached two 3000K lightbulb product links below that might be a good fit for your desk. Though both products below have the same CRI and color temperatures available, the A21 bulb can produce more light than the A19 (800 vs 1600 lumens), which could be useful if your desk lamp utilizes a single bulb. Anecdotally, the 3000K A21 is also my lightbulb of choice for computer work and reading. 

​

We have also provided a link to a guide for selecting the right color temperature below, which could be useful for your purchase planning.

Which LED Light Color Temperature Should I Choose? 

3000K CENTRIC HOME™ Flicker-Free A19 10W LED Bulb 

3000K CENTRIC HOME™ Flicker-Free A21 15W LED Bulb

Does it matter if the bulbs do not fit entirely inside the canister?

Does it matter if the bulbs do not fit entirely inside the canister? 60-watt, CRI 95, 5000k Spotlights

Generally speaking, so long as the recessed lighting bulbs can fit securely within the light socket, it should not make a large difference whether the bulb end protrudes from the canister. 

That being said, please note that as our BR30 and A19 bulbs are not designed for fully enclosed fixtures, we would recommend installing them within canisters that are not fully enclosed so that airflow can assist in heat dissipation. 

E26 bulbs vs E27 bulbs

My wife purchased a bedroom ceiling light from Europe with an E27 socket base. So far installing an E26 bulb in the fixture has not worked and we now believe we require a true E27 bulb. Do you sell E27 bulbs? Any recommendations? 

Though the E26 and E27 base standards are very similar, some small differences in product measurements can cause E26 bulbs to be incompatible with E27 fixtures, or potentially cause performance and safety issues. 

That being said, we are happy to confirm that our E26 and E27 lights are compatible with global voltage standards, which means that our A19 E27 bulbs should function properly in your European fixture while using the North American voltage standard.

As we generally recommend 2700K color temperature for living areas such as bedrooms, we would recommend the 2700K E27 CENTRIC HOME™ Flicker-Free A19 10W LED Bulb (PN4007.27). 

Lighting Options for Photography and Reptile Habitat Needs

I'm currently researching lighting options for a home addition that's currently in process at our primary residence. This is essentially a shop that's 30x20, but CRI and overall brightness are critical. I'm a breeder of high-end Leopard geckos (reptiles), and accurate photography (color representation) is an absolute must. I can only assume that I should be targeting a CRI of 90 or higher. With my photography, I tend to err more on the side of daylight or cooler about Kelvin and have a strong distaste for what I would consider 'warm' lighting.

We are happy to confirm that we have several products available which could be a great match for your photography and reptile habitat needs. Further, we can also confirm that the vast majority of our products offer a CRI higher than 95. 

As a starting point, you may find value in our Lumen Estimation Calculator tool. By inputting the dimensions of the room including ceiling height, as well as selecting the primary use of the room, the tool can suggest a total lumen output and suggest the number of products required to meet the illumination goal. 

In the interim, we might recommend the NorthLux line of products, which are designed with photography and capture in mind. You may also be interested in our 99 CRI Absolute Series products, which offer D50 and D65 light that is virtually indistinguishable from full daylight. 

2700K vs. 3000K: Which is recommended for home and residential applications?

What’s the biggest seller between the 2700 & 3000? Do most prefer to use 2700 in bedrooms & living room, & 3000 in bathrooms, kitchen & laundry room? Is the 95 CRI best? Can they be used in enclosed ceiling fixtures? Running low on my old GE Reveal incandescent bulbs, plus would like to save on electricity. 

We have shared a blog post link below that compares the 2700K and 3000K color temperatures for home installations, which we hope proves to be helpful. 

​As CRI is a measurement comparing the quality of light output to that of natural sunlight on a scale from 0-100, we can confirm that the 95 CRI offered by our products will result in a very high quality of light output. 

Further, as the LED light bulbs contain internal circuitry which benefits from a moderate amount of airflow for heat dissipation, we do not recommend utilizing them in enclosed fixtures. 

Choosing Between 2700K and 3000K

Are y’all working on the development of your bulbs that can be used in enclosed fixtures like in my kitchen, hallways, laundry room & closets? Right now I can only use these for a bathroom vanity, a pendant light & lamps. Which is your bestseller for residential? The 2700 or 3000?

What do you recommend for use in enclosed fixtures to avoid flicker? Incandescent or halogen rather than LED that can be used in enclosed fixtures?

We are happy to confirm that we look forward to improving our flicker-free products to allow for enclosed fixture installation down the road, though we do not have an expected availability date for such a product at this time. 

We can also confirm that as many of our LED lights contain hardware and wiring that traditional halogen and incandescent bulbs do not utilize, they can malfunction when the heat being generated is not able to dissipate via a moderate amount of airflow. 

Our Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential might be a great option as they can be installed within enclosed fixtures without the need for airflow.​

Our customers tend to prefer 2700K for living areas such as bedrooms, where the 3000K temperature is more commonly installed within kitchens and bathrooms. Unfortunately, we do not have any sales data on hand regarding which option is most popular overall. 

​That said, please feel free to take advantage of our 30-day return policy if you would like to order both options to make direct product comparisons.

Recommended Color Temperature for Under Kitchen Cabinet Lighting

I finished my backsplash and I need a light that is soft to bring out reds, browns, and blues from slate. I was thinking 2700 before looking at your page. I have a place above a cabinet for the driver and a box for the dimmer switch below. One low-voltage wire goes down above the switch to a 32" cabinet bottom. Another low voltage wire goes up, to the ceiling, across the kitchen, and down below the cabinets (@20'), where I will have 23" 19" and 19" cabinets to light with a microwave to span over in the middle. I am stuck on 24V or 12V. Also, I am concerned about bringing the best colors out of the backsplash but also want a little more light on my counters for cooking. 

We can confirm that we generally recommend 3000K for kitchens and dining areas. That said, you may find that a warmer color temperature compliments the backsplash material better. we have provided a link below comparing the two color temperature options below, which we hope is helpful. 

To test which color temperature works best for your kitchen, we might recommend ordering some of our 2700K and 3000K A19 bulbs to make a direct comparison of the light output. 

We have also attached an informative article from our website below, which goes into the benefits of a 24V system over a 12V system. In short, the maximum combined length of the 24V version is greater than the 12V version, and 24V installations will encounter less voltage drop which can be helpful for installations where there is a larger wired gap between the power supply and lights. 

Choosing Between 2700K and 3000K

Advantages of a 24V LED system vs 12V

A large part of my concern is being able to do the two runs of tape lights off of one driver that will work with a dimmer switch preceding it.

One low voltage wire goes down @4' to a 32" cabinet bottom. Another low voltage wire goes @20' up, across the kitchen ceiling, and down to another row of cabinets: 23" 19" (30" span for microwave) and 19" 

We are happy to confirm that our LED strip lights can be wired to a power supply in parallel. We have provided a link to an instructional page from our website below regarding the topic, which we hope proves to be helpful for your installation planning. 

Connecting LED Strips in “Series” vs “Parallel”

The primary consideration will be ensuring that the lengths of wire between the LED strip lights and the power supply do not encounter voltage drop. That being said, the voltage drop can be minimized by utilizing the proper gauge of wire. To assist with reducing voltage drop, we have also attached a link below to our voltage drop calculator tool.

Does your A19 Bulb FCC-rated?

I am looking for your FCC rating on your bulbs. My studio is in my garage and a lot of led bulbs mess with my garage door opener I need FCC part 15B certification min.

We are happy to confirm that our A19 LED bulbs are FCC rated under ‘FCC Part 15 Subpart B: 2020 Class B’s. 

Do you have any dimmable flicker-free bulbs?

I came across your website in my search for flicker-free bulbs. I currently have Philips Hue bulbs throughout my home, and I am becoming more frustrated at their terrible flicker (primarily because it makes it impossible to record videos at 24fps, but also I suspect some of my headaches are caused by them.) I see you have the Centric Home bulbs (4005.27), which are 60W equivalent and are completely flicker-free. I also see you have Filament bulbs (4002.27) which are 40W equivalent and dimmable, however, they do not mention flicker-free at all, and looking at their Photometric Report I see a flicker percentage of nearly 20% - I don't know if this is high or low, but it certainly isn't 0. So I guess I have 2 questions: (1) Do you have any dimmable flicker-free bulbs, or will there be any coming to market soon? (2) If not, do you have any non-dimmable flicker-free bulbs that are 40W equivalent? 

We currently do not have any A19 bulbs which are both dimmable and flicker-free, though we do hope to introduce such a product in the future. 

The closest match for a 40W equivalent would be the Lux24 A19 filament bulb, though it is not flicker-free as you previously mentioned. 

That said, please feel free to take advantage of our 30-day return policy if you would like to try out our A19 filament bulbs and other products. 

As an alternative for your video recording, you may also be interested in our line of LED strip light products. Though the configurations are more involved than a typical light fixture, these products can provide both dimming and flicker-free output alongside a high CRI of 95+. In some instances, the CRI of our LED strip lights is as high as 99. These lights and power supplies are also designed to be compatible with smart home dimming systems, such as Lutron Caseta. 

What is the M/P ratio for all CentricHome, FilmGrade, and Ultra High A19 5W LED Filament Bulbs?

I have some questions about A19 bulbs:  

Are Lux24 and Ultra High 95 CRI A19 5W LED Filament Bulbs available in the E27 base?

The Lux24 and A19 Filament bulbs are not currently available with the E27 base. We apologize!

Difference between CentricHome 3000K and FilmGrade 3000K? 

We can confirm that the 3000K CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb and the 3000K FilmGrade™ Flicker-Free A19 LED Bulb are identical products that are provided with unique landing pages for marketing purposes. We do apologize for any confusion this may have caused. 

I would also like to know if there is a much smaller output and size of power supply for the LED strip available. I'm looking to modify my R7s wall lamp to use LED strips and the power supply must be small enough to fit at the back space of the housing.

We do not have any smaller power supplies, but third-party power supplies can certainly be used as long as they meet the minimum power capacity needs of the LED strip connection. Please see below for our online calculator which you may find helpful:

https://store.waveformlighting.com/pages/led-strip-power-supply-calculator-requirements

What is the M/P ratio for all CentricHome, FilmGrade, and Ultra High 95 CRI A19 5W LED Filament Bulbs?

The M/P ratios for the 2700K and 3000K are 0.49 and 0.55, respectively.

Avian Full Spectrum E26 A19 LED Bulb for Birds in E27 Socket

I am looking to purchase 100pcs of this. However, I am concerned as we use an E27 socket in Singapore, with 230v at 50hz.

As the Avian Full Spectrum E26 A19 LED Bulb for Birds product is of the same product family line as the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb product, we would then recommend the Centric A19 in the E27 version for your order. 

The E27 version of the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb offers an identical quality of output as the Avian A19, while also being compatible with global voltage input (AC90-240V/50-60Hz). As such, the 6500K E27 Centric Daylight A19 is expected to be compatible with the 230V at 50Hz output. 

High CRI 95 LED Track Lights for Art Studio Installation

I would like lighting for my painting studio that has a 95+ CRI rating, 5000K and 5000 lumens and I'd prefer to use in-track lighting so I'd need bulbs vs tubes. Please let me know if you have products to meet those specifications. I'd also like the track lighting if you carry that. 

For 5000K track lighting systems, we usually recommend the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio products. This item can deliver full-spectrum light output and offers a high CRI of 95+, though these BR30 bulbs have an output of 800 lumens per light, which is much less than the 5000 lumens referenced.

As an alternative, you may also be interested in the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product, though the wider beam angle may not be ideal for all track lighting installations where a precise illumination target is preferred. Additionally, you may also find value in utilizing wall-dimmer-controlled track lighting of the 5000K 99 CRI LED strip lights installed within ceiling-mounted channels. 

I like the Northlux 95 e26 but I’d prefer it to be dimmable. Is there a way to make that happen? If so do you have track lighting that will work with them?

If not, I think I may be interested in the LED strips, with dimmer and ceiling-mounted channels since they can be dimmed. I have a few questions. How bright do they get? It was suggested that I need 5000 lumens so how many would I need for a 300-square-foot room? Also, how does one change the strips, and how long do they last? 

We are happy to confirm that the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio product is indeed dimmable, and will work with both in-wall dimmers and fixture dimmers. 

Based on my estimates using the Lumen Estimation Calculator tool from our website, it appears that a 300-square-foot space would benefit from roughly 5,961 lumens. By inputting the ceiling height of the room within the calculator you will likely receive a more accurate estimate, as we input an 8-foot ceiling height in my calculation.

The above illumination target can be accomplished by utilizing 16 feet of the LED Strip Light products, which can output 375 lumens per foot. 

As the ABSOLUTE SERIES™ LED Flexible Strips have a three-year warranty, please feel free to contact us if you experience any product failure within that window, and we would gladly provide a warranty replacement. 

When replacing the LED strip lights, we usually recommend utilizing the 3M ‘adhesive remover’ product, though some customers find value in additionally utilizing thin chisels to pry the adhesive off of the aluminum channels. 

​

Dimmable A19 Bulbs for Recording Studio

I'm looking for a solution in my recording studio to add a light just like yours but with the option to dim. Do you have any recommendations on how to accomplish this with your lights? (Maybe on a special dimmer? 

Though we can confirm that the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulbs are not compatible with dimmers, we do have a few other options that we might instead recommend. For example, the Full Spectrum E26 BR30 LED Bulbs feature the same high CRI of 95+ as the Centric A19 bulbs, while also being compatible with light fixture dimmers and wall dimmers. 

Another option, though more complex in the setup process, might be the CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail products, which are available in most of the same color temperatures as the above A19 bulb. This product can be paired with wall dimmers and in-wall power supplies, as well as 24V DC-plug power supplies and the LED Dimmer.

High CRI 90+ Replacement Lights for Indoor Installation

My decorator wants me to replace my bulbs with CRI 90 or higher to improve the natural color of the room. I'm new to these bulbs and would appreciate your assistance. These are for indoor lights. 

As you consider the options in our catalog in the interim, it might be helpful to know that our products offer a CRI of 95+, which means that the quality of light output is extremely similar to full noon daylight. We have also attached a few instructional resources from our website below, which we hope prove to be useful for your purchase planning.

Which LED Light Color Temperature Should I Choose?

Home & Residential Lighting

High CRI LED Lighting

The lights I will be replacing will be in the bathroom, bedroom, and one in the kitchen above the sink. The bulbs that are in now make the walls look pink instead of light gray. I have four bulbs over the counter in the bathroom. I’m hoping to have not just better color, but good light for makeup application. The bedroom had an overhead with two bulbs.

I have two flush mounts in the kitchen and the dining room that have this piece with a bunch of little Led lights. The hallway has the same thing. I have never seen this before, so have no idea if it can be changed to just regular bulbs. I would like the bathroom and kitchen to be bright, the bedroom a little softer.

Though we, unfortunately, do not have replacements for the embedded LED light fixtures within the dining room and hallway fixtures, we do have A19 products that appear to be compatible with the bathroom, bedroom, and kitchen light fixtures.

As referenced within the previously provided article, we generally recommend utilizing 2700K for living areas such as bedrooms and hallways. For kitchen spaces and dining areas, we would instead recommend utilizing 3000K lights. 

As such, I recommend our 2700K and 3000K CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulbs for those spaces. That said, please note that these A19 lights are not compatible with dimmers. If you have space that might benefit from in-wall dimmers, we would then recommend the Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential light (though please be advised that this item is out of stock until August 16th). 

These products can offer not only full-spectrum light output, but also feature a high CRI of 95+. As CRI is a measurement for how similar the quality of light is to full daylight on a scale from 0-100, I believe that these lights would benefit each room with much improved high-quality output. 

Full-Spectrum LED Bulbs for Residential Lighting

We are looking to replace our std LED with full spectrum and have some questions regarding the correct ones to use. They will have the E26 base but would like some guidance on the other features. 

We can recommend our CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulbs, which are full-spectrum, use the E26 base, and are available in the most common residential color temperatures of 2700K and 3000K.

Alternatively, you may also be interested in our Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential, which is a filament-style LED bulb that uses the E26 base, and is also able to offer full-spectrum light output. 

Recommended LED Bulbs for Puppy Photography

We’re having lots of trouble photographing our puppies and maintaining the correct color of the puppies. I came across your lights and I believe they were the answer to our problem. My question is we have a permanent area set up for taking pictures of our puppies? It is in a larger room so do I need to be concerned with just lighting up the area around the puppies or do we need to light the whole room? The room is 12’ x 20’ the puppy area is 5’ x 5’. The puppy photography area is raised off the floor about 3’. The ceiling is angled 7’ to 9’. Also, the best choice for bulbs?

In our experience, studio spaces for photography can be uniformly lit, though often the lights are adjustable and targeted towards the subject area of capture. In this instance, that would be the puppy stage.

In the interim, we would recommend the FilmGrade™ Flicker-Free A19 LED Bulb, which is available in both tungsten and daylight color temperatures (3000K, 5600K) which are often used for film and photography.

By inputting the dimensions of the room into our Lumen Estimation Calculator, it suggests 24 units of the above A19 bulbs (totaling 19,111 lumens) for even illumination of the room for photography purposes. Alternatively, to light only the 5x5 stage area, you would only require three units of the above A19 bulb (totaling 1,991 lumens). 

Do you have a full-spectrum light compatible with 19W CFL fixture?

I just got a new desk lamp, and it came with a 19W CFL spiral bulb that gives a horrid yellow light. Hate it! Do you have a full spectrum light in this configuration? I only need one bulb, but would probably order two to have a backup.

So long as the 19W CFL utilizes the standard E26 base, which is likely listed on the fixture label, then our full-spectrum A19 bulbs should be fully compatible with the desk light.

As such, we might recommend our 3000K CENTRIC HOME™ Full Spectrum Flicker-Free A19 LED Bulb, though please note that it is currently out of stock until May 24th. Generally speaking, 2700K-3000K are great color temperatures for living spaces, though some may prefer a cooler color temperature for productivity.

Compatible Power Supply and Dimmer for LED Strip

I am in the process of building a house with lots of LED strip lighting and would like to use your FilmGrade series in 3,200K and your Centric Daylight Series in 4,000K. I believe I can use these two dimmable power supplies. It isn’t quite clear to me what the difference between these two is. Could you please recommend a product? Also, in the list of compatible dimmers that are available for both of these power supplies, I did not see the Lutron Sunnata dimmer STCL-153PH-WH. I would expect this dimmer to be compatible. 

The primary difference between these two items can be found in the product dimensions, as the Centric Series power supply has a smaller footprint which can be helpful for some installations that have less available space. The secondary difference is that the TRIAC can offer 120W of 12V power, whereas the Centric can offer 96W of 12V power.

Compatibility-wise, we can confirm that either will work well with any of our LED strip light products and can provide flicker-free functionality.

Further, the Lutron Sunnata STCL-153P was tested and confirmed for compatibility. Please see the below document.

https://www.waveformlighting.com/datasheets/CD_3093.pdf

What is the flicker rate of the Lux24 Circadian bulb?

I purchase a pair of the Lux circadian bulbs a while back. What is the amount of flicker in those bulbs? I am interested in purchasing flicker-free lights.

We can confirm that the Lux24™ Circadian LED Bulb has a flicker rate of 29%. As such, they are unfortunately not flicker-free.

For flicker-free performance, we generally recommend our other A19 bulbs, such as the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb. 

Which bulb do you suggest is most similar to the Lux24 in terms of impact on sleep and is fully flicker-free?

Though the filament bulbs in our catalog are unfortunately not flicker-free, the next closest product match would be the 2700K CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb. This item is flicker-free and available in the warm 2700K option, which is closer to the 2400K output available in our Lux24 product than our other A19 bulbs.

What is the difference between the A19 LED Bulbs?

You list a variety of 5000k and 800-lumen standard bulbs. How do these differ? They are all listed as 95 CRI. Some are in stock and some are not. Trying to decide. 

As our A19 bulbs are from the same family of products, each can offer identical performance and the same high CRI, which is a measurement of how similar the quality of light is to daylight. As such, the only differences among the A19 products can be found in the color temperature being offered.

If you would like any assistance in selecting the right color temperature for your installation, I have attached a helpful blog post link below.

Which LED Light Color Temperature Should I Choose?: https://www.waveformlighting.com/home-residential/which-led-light-color-temperature-should-i-choose

Do your A19 bulbs work in recessed ceiling fixtures?

I was wondering if your flicker-free A19 bulbs will work in recessed ceiling fixtures. I understand they don’t work in fully enclosed fixtures but these have at least the end of the bulb exposed to the air. These fixtures would normally take floodlights but I don’t think there is a flicker-free floodlight option, correct? 

We're happy to confirm that the A19 products are compatible with recessed ceiling fixtures, and are best when used within fixtures that allow for moderate airflow.

If the A19 bulbs are connected to a dimmer without utilizing the dimmer functionality, the products should function properly. When using the A19 products with dimmers, you may encounter flickering or atypical functionality. 

Unfortunately, we do not have a flicker-free BR30 product available at this time. 

Flicker Rating for Ultra High 95 CRI A19 5W LED Filament Bulb

I wanted to clarify what the flicker rating was for these bulbs. Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential I wanted to get the flicker-free ones, but I live in California. 

We're happy to confirm that the flicker-free A19 products have been recently improved and can be shipped to California. 

The flicker rating can be found on the photometric reports below.

2400K Photometric Report

2700K Photometric Report

Further, you may want to consider the CENTRIC HOME Flicker-Free A19 10W LED Bulb available on 2700K and 3000K. These bulbs are flicker-free. 

LED Bulbs Recommendation for Home Lighting

I'm looking to replace the existing light bulbs in the home we’re moving into. They’re A19. Can you help me understand the differences between the following: Centric Home Full Spectrum flicker-free, Centric Daylight Full Spectrum flicker-free, and FilmGrade flicker free

The applications are bedrooms, bathrooms, offices, and some common areas like a hallway, and laundry room. Some of the bulbs will go within a light fixture that has yellow glass. 

What am I looking for? Flicker-free, good-quality light. 2700K and 6500K seem too far on the color spectrum. Probably 3000K to 4000K is what we’re looking for.

Generally speaking, we find that living spaces generally benefit from 2700-3000K color temperatures, where office spaces benefit from 4000K. However, I have provided a few links below which might assist in selecting the right color temperature for each of the spaces referenced.

Which LED Light Color Temperature Should I Choose? https://www.waveformlighting.com/home-residential/which-led-light-color-temperature-should-i-choose

Guide to 2700K vs 3000K: https://www.waveformlighting.com/home-residential/choosing-between-2700k-and-3000k

Guide to 4000K: https://www.waveformlighting.com/home-residential/should-i-choose-4000k-led-lights-an-in-depth-look

Further, as the A19 products referenced (Centric Home Full Spectrum flicker-free, Centric Daylight Full Spectrum flicker-free, FilmGrade flicker-free) are of the same family line, the primary difference will be found in the available color temperatures. As such, each offers the same high CRI and will be able to provide identical performance.

​Finally, please note that our A19 bulbs will require a moderate amount of airflow for heat dissipation. As such, we advise against use within completely enclosed fixtures, as this may cause higher than normal failure rates.

Full Spectrum Lighting for Horse Stall

I’m looking for a Full Spectrum UV lighting system for my horse's stall during the fall/winter - he gets depressed and irritable. Is this something you can help me with/offer?

Our various CENTRIC DAYLIGHT products would be a great fit for general full spectrum applications, including animal husbandry applications. Our lamps do not, however, include any UV radiation, so if that is a firm requirement, we would recommend finding a supplemental light source that includes the UV portion of the spectrum.

​Below is a link to our most popular full spectrum bulb which uses a standard E26 medium base and might be a great starting point:

​

High CRI 6500K bulbs for Digital Photographic and Color Matching Applications

I need a few Hi CRI, 6500K bulbs for 2 separate uses:

1) Digital photographic slide capture and then editing on a 6500K color-corrected monitor. I have one of your 6-inch, white sample LED strips to try for lighting behind the monitor. I need Edison bulbs for indirect room lighting. I've looked at your website and found a few 6500K CRI >90 bulbs that might work, including some with high R-9 ratings. Do these bulbs need to be D-65 rated? What is your recommendation for this use?

2) Color-matching fabrics and buttons, etc. Can I use the same type of bulb or is a D-50 bulb more appropriate? Suggestions?

I noticed several dimmable Hi CRI bulbs listed, but I could not find their R-9 rating. Can use 1 & 2 be accomplished with a dimmable bulb, or does that add too much variability to the lighting?

As we currently do not offer 6500K filament bulbs at this time, we might alternatively recommend the Sidewinder™ LED Flex Strip for D65 Bias Lighting product, which is D65 calibrated and designed for bias lighting for monitors intended for color-correction.

Regarding the benefits of D65 vs D50 for your fabric sample color matching purposes, I have provided two links below from our blog, which each include sections comparing the benefits of the two for working with color. 

​Regarding the R-9 value, the specification sheets and photometric reports linked within each product page will be able to provide the R-9 output details.

What is D50?: https://www.waveformlighting.com/color-matching/what-is-d50-for-graphic-arts-printing

What is D65?: https://www.waveformlighting.com/color-matching/what-is-d65-and-what-is-it-used-for

I'm confused by the photometric test reports, or perhaps I don't understand your part numbering system. This makes it look like the D-50 calibrated bulb is the same as the Centric 5000K bulb(based on the report PDF) and the same as the NorthLux 5000K bulb based on the web page part number listing.

We can confirm that the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) product and the 5000K NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio are identical products which are provided unique landing pages for marketing purposes. This can be noted by the shared part number of 4005.D50.

As such, you can expect that the performance will be identical across both items. We would like to sincerely apologize for any confusion that this might have caused.

Avian Full Spectrum Light with UV-A & UV-B

What would be the most optimal setup regarding my situation and needs? I have a background as a lighting designer and have experience in LED fixtures and concepts with implementing UVA and UVB but using HO Fluorescents to create the output or affective properties. At that rate, it’s a product that requires special care and consideration. 

With that said, based on the current market availability, would you say your line of lamps holds its own at the top for full spectrum and benefit in health, and intended purpose in Avian Supplemental Lighting?

Within the visible spectrum, I can confirm that our LED products can offer a high-end CRI output of 95-100. This CRI number defines how similar the spectral output is to full daylight.

That being said, please note that these products do not have ultraviolet output. If UV-A and UV-B output is necessary for your application, we might recommend utilizing a third-party option that offers UV-A/B output as the primary light or utilizes a UV-A/B product in tandem with our high CRI products.

For the A19 form factor, we would recommend the Avian Full Spectrum E26 A19 LED Bulb for Birds product, which offers a CRI of 95.

As an alternative, we might also recommend the 6500K ABSOLUTE SERIES™ LED Flexible Strip, which offers a CRI of 99, making it virtually indistinguishable from daylight. A customer that I recently corresponded with chose this product for their own avian installation, thanks in part to the high CRI output.

I have also attached links below for two layout guides, which illustrate how the absolute series LED light strips can be configured. This page includes links to the optional and required accessories, as well as additional instructions.

LayoutMaps™ - LED Strip Light Layout 3002_3E

LayoutMaps™ - LED Strip Light Layout 3002_3C

For LED Strip, I don't need 16’ of it and saw you have it per foot. I don't remember off hand how many watts/ft they were, but I'm sure 4’ is all I need. If we take that and couple it with what? what would your suggestion be in lamps for producing the UVA & B that we need? Are you familiar with the %’s that are safe and targeted for, in my case, exotic birds (large)? 

Though many of our other LED strip lights are available in 3.2 ft increments, the absolute series 99 CRI LED strip lights are currently only available in 16.4 ft reels. We apologize!

To power a 4 ft length of the LED strip light, we would recommend a single 12V FilmGrade™ DC Power Supply for LED Strip. As the strip lights contain pre-applied barrel jack adapters, no additional connecter accessories would be required.

Further, as our expertise is limited to our own products we currently do not have any UV-B product that we could recommend and are not aware of the safe UV-B exposure levels that avian species might require.

Would it possibly lessen the hazard of installing E26 bulbs in the E27 socket at 120V?

I read with interest your blog article "E26 vs E27 Bulbs - Interchangeable? Not Necessarily!", but it left me with a question. Apparently, there are lighting fixtures sold here in the US that have E27 sockets. While your article calls out the hazards of E26 bulbs in E27 sockets at 240V, it did not comment about E26 in E27 at 120V. Would that possibly lessen the hazard? 

Though the design differences are slight, the small gap present between an E26 light installed within an E27 socket base can cause arcing or hazards that are separate from any potential voltage compatibility issues that might arise.

As our E27 and E26 bulbs both are designed for global voltage standards, we can confirm that the E27 versions can be safely used within fixtures designed for European or other voltages.

For example, if a European chandelier with E27 sockets was to be used with 120V AC North American voltage standards, we would recommend using our E27 A19 bulbs, as they are capable of being used with 120V AC voltage even though the base is typically used in global fixtures.

Could you suggest a LED bulb to look at the exterior house paint colors?

Could you please suggest a bulb for me to look at the exterior house paint colors? swatches (indoors, of course). Could you please suggest a bulb I would use to look at exterior house paint color swatches? 

Based on the details provided, we might recommend the 6500K NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product, as the D65-calibrated high-CRI output can closely simulate north-facing daylight.

If a more neutral daylight color is preferred, we would then recommend the 5000K color temperature of the same product.

Color Accuracy Bulb for Building a Lightbox or Photo Booth

I was interested in a few of the products you guys sell and was wondering do you guys have a flicker-free high CRI bulb with a color temp of 6500k. I went through the bulbs and am still confused about all these options. I was looking at 4005.D65 4005.65, and some of the other NorthLux and centric series and wasn't sure what would be best for color accuracy, I am building a lightbox/ photo booth for checking the color accuracy of plastic samples.

Based on the details provided, I would recommend the 6500K (D65) NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio products, which I can confirm as being flicker-free. 

​This product is also designed to conform to the ISO D65 standard, which is beneficial for installations that require an extremely low variability in light output.

If you would like to purchase a few of the options previously mentioned to make direct product comparisons in your space, please feel free to take advantage of our 30-day return policy.

Is the NorthLux™ 95 CRI BR30 LED Bulb also flicker-free? And are the specification and other product documents available to look at?

The NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio, as well as our other BR30 bulbs, share a 6% flicker rate. Though not totally flicker-free as our A19 bulbs family of products are, it does offer a fairly low flicker rate.

In the interim, I have provided a link to the product specification sheet below, which I hope proves to be useful:

LED Bulb for Mimicking Sunlight During Filming

I have a hobby that involves filming videos of products, but I have been very limited in trying to chase the spots of sunlight in my house. I would love to be able to film at all odd hours of the night or whatever. I am looking to mimic the noon sun, preferably. 

The primary product that comes to mind is the 5600K FilmGrade™ Flicker-Free A19 LED Bulb, which is specifically designed for film and photography purposes.

For alternative options that are slightly warmer and slightly cooler while offering the same performance and high CRI, you might also be interested in the 5000K or 6500K NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio products.

Though not traditional bulbs, as an alternative you might be interested in the NorthLux™ 95 CRI T5 LED Linear Light Fixtures. These integrated fixtures can be installed in a number of ways, and do not require any additional hardware or power supplies.

Is there any difference between the A19 FilmGrade and NorthLux besides color temperature?

Is there any difference between the A19 FilmGrade and Northlux besides color temp? I need to color-match prints and originals to my calibrated monitor. I have the FilmGrade now and they seem a bit cool.

The NorthLux products are slightly different than the FilmGrade™ Flicker-Free A19 LED Bulb, in that they have been calibrated to conform to the ISO D50 and D65 color standards. These color standards can be quite useful for creating lighting installations that require a very constrained level of variability in the light output.

Beyond this difference, the performance should be identical as these items are both of the same product family. 

LED Lighting for Art Studio and Photography

I'm a painter and I've looked through your website and received quite the education. I have 4' CRI Phillips T-8 CRI 90 tubes I purchased years ago for overhead in my studio. These need to be changed but, my first concern is lamps for photographing my oil paintings. Varnish applied to oil paintings creates glare. For photography, I'd like to have lamps on either side pointing at 45 degrees to the painting, with linear polarizing film filters plus another polarizing filter on the camera lens.

The wattage is equivalent to a 60 W incandescent. For photographing painting the f-stop needs to be fairly high to have a wide depth of field to keep the complete painting in focus. I'm assuming the E 26 A9 would require multiple bulbs on each side due to the distance from the painting and the light loss due to the linear polarizing filters. Your bulbs/ lamps are appealing. 

Our NorthLux A19 lamps do indeed sound like a great option for your painting photography. These bulbs feature 95 CRI and daylight-calibrated light output, which means they are perfect for image capture without any loss of color accuracy. Because the light source is fundamentally calibrated to full-spectrum daylight, there should not be any need for white balance or color correction adjustments.

​The only "unknown" at this point, as you mention, is the total brightness needed. This is a bit more difficult to provide a definitive answer to, as various factors such as camera ISO settings, canvas size, distance from the canvas, etc can all play a factor. My recommendation would be to try out various configurations such as lamp quantity, orientation, and distance to see what works best for you. The A19 / E26 form factor ensures that these lamps will fit in virtually all standard bulb fixtures.

​I certainly agree that multiple lamps from various angles would be helpful, especially to ensure that you have even illumination across the painting when the photographs are taken.

Do you have dimmable 75W-100W A19 Bulbs?

I'm looking for a "dimmable" A19? or similar Approx 75-100W equivalent to be used in bedside lamps operated by Lutron RA2 Dimmers (RRD-3LD). Can you provide it?

Unfortunately, the closest option we have for a dimmable A19 lamp would be our filament lamps, which are only available in 40-watt equivalent.

​I also need to purchase LED Flex Strip (4000K) in both 12V and 24V. I do not see 400K Strip in 4000K in 12V on your site.

The 4000K LED strip is only available in 24 volts. We unfortunately do not offer a 12-volt version.

​​Do you sell cut lengths of IP67 Rated Silicon LED Strip? 

We do not offer any IP67 or outdoor-rated LED strip lights at this time.

Full Spectrum and Flicker-free LED Recessed Lights

It has been recommended that the recessed lights in my autistic son’s basement bedroom with a low ceiling be full spectrum non flicker. What would you recommend? I find LED lights generally extremely bright. Also, I’ve read that the flicker has more to do with the electricity going to the lights rather than the bulb. Should I change the very old dimmer switch? 

Though we would usually recommend our BR30 products for your recessed lighting, (such as the 3000K Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential product) these items are unfortunately not flicker-free. As such, these products might not be a good fit for the installation.

I ordered 6 x CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulbs (2700K). It says they are not suitable for enclosed fixtures. Would they be okay for semi-enclosed? I have a couple standing lights with 3 x cones that house the bulbs. I also have the cone desk lamps.

We're happy to confirm that most semi-enclosed fixtures should be safe to use, so long as there is adequate venting for heat dissipation.

For context, unless a fixture has a way of easily dispersing the heat generated by the bulbs, the hardware within the bulbs can overheat and cause the product to encounter errors. 

Are the Centric Home and FilmGrade A19 Bulbs identical but labeled for different uses?

I was looking for information for a couple of lights, specifically the A19 Home Centric 3000K and the A19 Film Grade 3000K bulbs. The Spectral Analysis sheets listed under the support page for the two bulbs pull an identical document. Two questions. Are the bulbs identical but labeled for different uses? It's very common to see something like this. If they are not the same, would it be possible to get the spectral analysis documents updated or at least emailed to me?

We can confirm that the 3000K CENTRIC HOME™ A19 bulb and the 3000K FilmGrade™ A19 bulb are identical products which are provided unique landing pages for marketing and SEO purposes.

As such, you can expect that the performance would be identical across both items. That being said, we would like to apologize for any confusion this might have caused.

What is the difference between Centric Daylight and Avian Full Spectrum Bulb?

What is the difference between the Centric Daylight 6500 Bulb and the Avian Spectrum Bulb? I'm trying to purchase bulbs for a client who wants to simulate sunshine indoors. Or do you recommend a lower Kelvin? 

We can confirm that the Avian Full Spectrum E26 A19 bulb and the 6500K CENTRIC DAYLIGHT™ A19 bulb are identical products which are provided unique landing pages for marketing purposes. As such, you can expect that the performance would be identical across both items. That being said, we would like to apologize for any confusion this might have caused.

As CRI is a measurement that compares the light quality to that of natural sunlight, the higher the number better. As each of our A19 bulbs offers a high CRI of 95+, the color temperature selection will likely come down to personal preference and use of the space. As an example, for living spaces and kitchens we might recommend 2700K or 3000K. For offices, we would alternatively suggest 4000K.

Full Spectrum 4000K Bulbs in 600 Lumens?

I would like to buy a whole bunch of 4000K E26 bulbs for my house, but I've found that the 800 lumens are just too bright for me. Do you offer the bulbs in 600 or 650 lumens? If not, can you direct me to a company that does? 

Though we do offer some A19 E26 products with a 450-lumen output such as the Lux24™ Circadian LED Bulb and Ultra High 95 CRI A19 5W LED Filament Bulb, the rest of our E26 products have an 800-lumen output. That being said, we, unfortunately, do not have any alternative manufacturer products that I could recommend at this time.

However, it might be helpful to know that we offer a 30-day return policy for all orders. If our LED lights are too bright for your home, simply let us know and we will promptly issue a prepaid return label.

Difference between Centric and NorthLux Products

Would you be able to let me know if there is any difference between the Centric bulbs and NorthLux bulbs with the same color temperature? I noticed that there are a number of products where there are Centrix and NorthLux bulbs with the same CCT, wattage, and price, and online pictures. I'm curious as to whether the products differ in some way. 

We can confirm that some products, such as the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio and the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) are actually identical items that are given unique landing pages for marketing purposes. 

​By comparison, though the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED product is of the same family line, the 5000K color temperature does not conform to the D50 color standard as the above products do.

We do apologize for any confusion this might cause in your order planning. As a general note, identical products can be noted by the shared part number. For the above D50 products, that number is PN4005.D50. In these instances, the functionality and performance will be identical, though the color temperatures available might change.

2700K LED Bulbs in E26 Base and 120V AC

I need a small pack (max. 6 pieces) found the bulb online but not CLEAR. 

We're happy to confirm that both of the products below are available in 2700K, utilize the E26 base, and are available in 6-Packs. Further, both of these products are compatible with 120V.

High CRI LED Light for Video and Photography

I want to buy high-CRI lights for photography and video. I don’t know what exactly I need, and if you sell ready-to-use lights. If you can please give me some recommendations and prices that would be great. 

We're happy to confirm that we sell both lighting fixtures and light products such as A19 bulbs and LED strip lights on our storefront website.

If you would like to let us know a little bit more about the ideal light fixtures for your studio space, I would be more than happy to provide some product recommendations.

In the interim, the first products that come to mind are our FilmGrade™ Flicker-Free A19 LED Bulbs, which are available in 3000K and 5600K for cinema and video applications.

If you would rather utilize LED strip lighting in your studio space, we might alternatively recommend our FilmGrade™ WHITE LED Strip Lights, which are available in multiple color temperatures while offering the same high CRI of 95 as the above A19 product.

What is the difference between the Centric Daylight 5000K and Northlux 5000k bulbs?

What is the difference between the Centric Daylight 5000K and Northlux 5000k bulbs? What is the R9 rating for the Centric Daylight 5000k bulb? Also, do the 5000k bulbs give off a blue hue to them? 

The difference between the CENTRIC DAYLIGHT and NorthLux bulbs is that the NorthLux bulbs are calibrated to the D50 and D65 color standards which may be crucial for certain visual tasks. Both feature 95+ CRI and R9 values of 80+.

The 5000K lamps could certainly be perceived as being blue, especially during evening hours, and compared to incandescent and other warm white LED lamps. 

Here is an article going over some aspects of 6500K lamps, many of which would also apply to 5000K lamps:

NorthLux LED Bulbs for Art Gallery Lighting

Where in BC Canada can I buy your products? I went to 5000k bulbs to get daylight and found CRI an issue. You say your NorthLux solves these issues. Why don't galleries use them? I am told that they all use 3000k uniformly. If I paint under a 5000k or 6500k NorthLux then for sure, the work will look different under your NorthLux bulb. Won't it? Also, your NorthLux bulbs don't have an infrared and ultraviolet issue (as in halogen have UV issues.)?

For starters, we, unfortunately, do not sell our products through any distributors at this time. As such, all orders are currently submitted through our storefront website and shipped from our warehouse in Illinois. However, we do hope to offer broader international shipping options in the future.

Regarding color work, we can confirm that differences in color temperature can cause artwork to appear slightly differently. Further, our NorthLux bulbs are designed to output no UV or IR wavelengths. For more information regarding the spectral output, I have attached a link to the product photometric report below.

NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio Photometric Report: https://www.waveformlighting.com/photometrics/TR_4003.65.pdf

It might also be helpful to know that our FilmGrade™ Flicker-Free A19 LED Bulbs offer the same high CRI in the 3000K color temperature option. Hopefully, this option would allow you to create artwork that would not look different under the 3000K gallery lighting.

Does A19 LED Bulb for Art & Studio emit UV?

I'm wondering if the E26 A19 art studio bulb emits anything in the UV range. I'm photosensitive and just want to be really sure they're safe for me. I think wavelengths less than 400 nm are the harmful range. It's tricky to see that degree of resolution from the spectrum graph. 

We're happy to confirm that our A19 LED light products, such as the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio, are designed to emit no UV radiation.

As can be noted in the product spectrum test report, the spectral distribution trails off before the 400nm wavelength. However, you are correct that it can be a little difficult to see that specific range in detail. I will look forward to updating the reports sometime in the future with ideally better graphics.

6500K NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio Spectrum Test Report: https://www.waveformlighting.com/photometrics/TR_4003.65.pdf

Are your NorthLux A19 bulbs flicker-free?

Are your NorthLux bulbs flicker-free, like your Centric bulbs? Also, do you offer a watt equivalence higher than 60, please?

We are happy to confirm that the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product features the same flicker-free operation as the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulbs.

Unfortunately, we do not have a higher-wattage A19 bulb available at the moment. You may want to consider our A21 Bulbs, which are equivalent to a 100W incandescent bulb. 

Difference between NorthLux 5000K & D50 A19 Bulbs

I can see using the D50 color-matching bulbs near the computer to check digital images of my paintings. But what's the difference between these A19 bulbs and the Northlux A19 bulbs at 5000K?

We can confirm that the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product and the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) are identical products that are provided unique landing pages for marketing purposes. The key feature that these items share is the D50 calibration, which can be very beneficial for color-sensitive work such as print design. This can be noted by the shared part number of 4005.D50.

Similarly, the Ultra High 95 CRI 6500K E26 A19 LED Bulb for Jewelry & Display product is from the same family line and offers an identical CRI of 95+ as our other A19 products.

As such, you can expect that the performance will be identical across these items, though each is calibrated slightly differently. However, we would like to sincerely apologize for any confusion that this might have caused.

​

What is the difference between the Centric and Film Grade A19 bulbs?

What is the difference between the Centric and Film Grade A19 bulbs? Are they both completely flicker-free? 

We can confirm that both products feature flicker-free operation, and are extremely similar in design. The primary difference between these items can be found in the color temperature options that are available.

Ceiling Fan Lights Recommendations

I'm trying to find bulbs for a ceiling fan that holds 4 bulbs. I do notice any of my lights that flicker so that's a big deal for me. Any suggestions?

I was thinking about buying a centric home with 95 bulbs but I don't know if I prefer 2700 or 3000. Can't make up my mind today but I'd be glad for some advice.

I do like some smaller shaped lights from Lowes (utilitech) but they don't seem to have them anymore. Do you make any smaller bulbs but still with a medium base?

Based on the details provided, we might recommend the 2700K or 3000K option of the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb product, which is designed to offer flicker-free functionality.

Regarding the selection between 2700K and 3000K, your choice may come down to personal preference. For living rooms and bedrooms, we generally recommend the 2700K option, whereas, for kitchens and dining areas, we would alternatively recommend the 3000K option.

It might also be helpful to know that we offer a 30-day return policy. If the color temperature selection winds up not working well for your space, simply let us know and we would be happy to issue a prepaid return label.

Regarding the bulb sizes currently available, we can confirm that we currently do not have any bulbs smaller than A19 available at this time. However, we are looking into expanding our product line within the near future, and hope to include more standard sizes.

Daylight Bulb to View Prints for Color Accuracy

I am looking for a daylight bulb to screw into a regular tabletop lamp to view prints for color accuracy. I'd like to get the brightest bulb available to make sure IU has full lighting coverage. Which do you recommend?

Based on the details provided, we might recommend our D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) product. This item is designed to be calibrated to the D50 standard, which could be quite valuable for print viewing and color accuracy.

Suggested Color Temperature for Residential Lighting

Is there a big difference between ordering the bulbs from you all and buying bulbs from Home Depot or Lowes? 

Also, Can you tell me what kelvin temp I would need for (recessed lighting in the kitchen, living room ceiling fan, entryway chandelier, and bedrooms)?

While there are many great LED products available on the market, our products have been designed to offer a higher CRI and better color consistency than much of what you will find available at Lowes or Home Depot.

The CRI listed within our product pages represents how similar the light is in quality to that of natural sunlight. While some LED products offer a CRI of 80, products such as our CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb offers flicker-free functionality and a CRI of 95+.

For living rooms and bedrooms, we generally recommend the 2700K option, whereas, for kitchens and dining areas, we would alternatively recommend the 3000K option. For recessed lighting, you might be interested in our 3000K Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential products.

For more information regarding the right options for each space, I have provided a helpful blog post from our website below which might prove to be useful for your planning purposes.

Flicker-free LED Bulbs for Golf Sim Room Lighting

I'm looking for bulbs that are flicker-free to use in my Golf Sim room. I have two cameras that I use and the current LED lighting I have flickers which can be hard on the eyes and annoying. 

The first product which comes to mind is the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb. This product is available in both 5000K and 6500K and offers flicker-free performance that your installation might benefit from.

The 6500K option might be of specific interest to you, as the light emitted by the product will closely simulate that of full direct sunlight. For more information regarding the differences between 5000K and 6500K, I have attached a helpful blog post from our website below.

Do your Avian LED Bulbs emit UV-A or UV-B?

I see that one says NO UV, and the other does not say one way or the other. It is my understanding that our Parrot Family birds do need Full Spectrum but that includes some UV-A and UV-B. 

We can confirm that these products are not designed to emit UV-A or UV-B, which can be noted on the lighting parameter analysis report link below for the A19 Avian bulb product. As such, it is entirely possible that specific avian families or breeds would benefit from specific adjustments to lighting, including the use of lights with a greater UV output. 

To this end, we might recommend reaching out to an avian specialist for specific instructions on creating ideal lighting environments for your parrots.

Household Bulbs for House Plants

I'm trying to find a regular household-type bulb that would be great for daily use and house plants. I'd like to use adjustable arm table lamps, or pendants to light single plants or a small display and match temp to all other bulbs in the home. I'll change all if necessary. 

Based on the details provided, there are a few different products that we might recommend depending on the preferred color temperature output.

For starters, we might recommend the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb product. Though these are not dimmable, they offer flicker-free performance and a high CRI. Further, the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential products could look quite nice on a shelf display among plants.

We have attached a blog post link below from our website regarding color temperature selection, which might be helpful for your planning purposes.

Which LED Light Color Temperature Should I Choose?: https://www.waveformlighting.com/home-residential/which-led-light-color-temperature-should-i-choose

As our A19 bulbs will offer a very similar quality of light output, the right option might be better defined by the purpose of the space. For example, while we might recommend a 4000K option for a home office space, we would alternatively suggest a 3200K for a reading area.

I read the blog but didn't see anything about plants. Maybe I should rephrase my question. Which of your A19 bulbs has the correct spectrum and other properties to grow healthy houseplants? These plants are typical tropical varieties composed of mostly foliage, not flowering. Most prefer bright to medium indirect light. Some small 6" ish pots on a tabletop and some large floor plants. I just want to use a variety of attractive lamps that accept regular bulbs.

Though our High CRI A19 bulbs have not been specifically designed for horticulture as some of our other products have been (such as the PhotonTube™ T5HO LED Grow Light Tube for Horticulture product), I am happy to confirm that they offer an extremely similar full spectrum light output to those of our horticulture-focused products.

Regarding the right color temperature for your installation, you might find benefit in either the 4000K or 6500K options of the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb.

While the 4000K provides an output that simulates late-season light, the 6500K option will offer light that is very similar to natural daylight and simulates the light which occurs in early-season growth periods. For an in-depth analysis of the technical benefits that our full spectrum lighting has on plant growth, we have attached a terrific blog post from our website below.

LED Lighting for Indoor Plants

I am looking for light bulbs to place in my house lamps for indoor plants. Would you be able to make a few suggestions on which bulbs to purchase? I did see that you have a horticulture section- but I am not looking to install any tube lighting, and wasn’t sure what other options there are. 

Generally, we do not recommend the use of house lamps for indoor plants, as the illumination levels provided by such lamps are insufficient for plants. Typically, plants require brightness levels that are similar to natural daylight, and this will require the use of higher power fixtures such as the ones shown in our horticultural daylight product showcase.

​If you do want to proceed with the use of standard house lamps, we do have several A19 products which would be a great fit; however do keep in mind that the light levels would merely be "supplemental" rather than a substitute for natural daylight.

Please see below for our A19 lamps which would be a compatible from a spectral perspective:

Artist Space Lighting

I'm an artist and want help in picking the right lighting for my studio. I think NorthLux™ 95 CRI LED Shop Light 5000K is the best choice, but I'd like to double-check. I see that it's back-ordered, when could I receive it? 

Our NorthLux line of products is indeed a great option for studio lighting!

Please tell me about other lighting that's good for an artist studio. The room is 10x12' with no natural light. Ceiling is about 8' high. I need great light over my table ,but if I can light the whole room that's even better.

Our options here would depend on the lighting fixture you would like to use.

​For example, we have some T8 LED tube lights which would require a 4-ft fixture to house the lamps. Alternatively, our A19 lamps will fit in standard screw-in lamp fixtures (E26).

​I have included the relevant product links below. If you can let me know a bit more about what you have in mind in terms of fixtures, please let us know and I'd be glad to assist.

Lighting Recommendation for Dark Apartment

I am in desperate need of lighting advice for a small, dark apartment with only one window light source per room - one in the bedroom and one in the living room. I intend to replace all light bulbs with as bright a light source as possible - including in floor & table lamps. I suffer from SAD and want to simulate as much natural light as possible. With having to be cooped up so much of the time due to the pandemic, this need has become critical. I don't know how to determine wattage but am willing to go for the brightest. 

Based on the details provided, we might recommend either the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulbs, or the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulbs.

As these products are extremely similar, and offer the same 95 CRI light quality and wattage, the primary difference can be found in the color temperatures available.

For selecting the right color temperature for your spaces, the below blog post from our website might prove to be useful: Which LED Light Color Temperature Should I Choose?

Full Spectrum and Flicker-free LED Strips for a Dark One-Bedroom Apartment

I want to put hidden lights all around the ceiling of a dark one-bedroom apartment. I like a full-spectrum LED. Please help me understand and choose the right product. 

We believe that a great first step would be utilizing our standard bulbs in the lighting fixtures in your space.

Based on the details that you provided, we believe that replacing the existing light bulbs could make a large difference at a significantly lower cost than the LED strip light products. As such, we have provided some product links below.

Due to the stated preference for lighting which is similar to direct sunlight, we recommend the 5600K color temperature option of the FilmGrade™ Flicker-Free A19 LED Bulb. 

​This product can be easily installed into standard lighting fixtures, has a 3-year warranty, and offers full spectrum lighting that will appear visually identical to that of natural sunlight.

BR30 vs A19 Bulbs for Artist Studio Space Lighting

I want to use the NorthLux 95 CRI E26 A19 LED bulbs in track lighting for a small space of 5 x 6 feet. How many bulbs would you recommend? Can you recommend a source or fixture that would be appropriate for the space?

Based on the details provided, we estimate that your 5x6 space would benefit from roughly 2,389 lumens to be properly illuminated for artwork creation.

As each of the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio products offers 800 lumens, we estimate that three bulbs could work well for the track lighting in your studio.

While there is not a specific light fixture that we could recommend, it might be helpful to know that our BR30 products are compatible with the standard E26-base track lighting systems that you might find in your local hardware stores.

Are there pros and cons to ordering the NorthLux 95 CRI E26 A19 LED Bulb instead? I see it is not dimmable, and the BR30 bulb is dimmable, but otherwise, I don't understand how they would differ in application. Can I use the E26 fixture with this also?

We're happy to confirm that the A19 bulb is compatible with E26 fixtures and that the performance will be largely the same as the BR30 bulb. The primary benefit offered by the BR30 bulbs is the narrow beam angles, which can be quite useful for track lighting systems with directional lighting.

However, if the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product winds up not working well in your space, it might be helpful to know that we have a 30-day return policy. Simply reach out to let us know, and we will issue a prepaid return label. 

LED Bulbs Products for Color Control in Photography

I photograph (multi-shot/PS stitched) original art and maps for large-format reproduction. Have you gotten any feedback on the best product, bulb, or strip for better color control? I have fabricated light fixtures in the past and would appreciate advice on recommended reflector specs.

Based on the details provided, there are a few products that we might recommend.

For example, in the event that you were to utilize traditional E26 lamp fixtures, we might recommend the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) product.

However, if you were hoping to utilize traditional tube light fixtures, we might recommend the D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000) product.

A19 LED Bulbs for Photographing Paintings

I'm looking for the best A19 bulb for photographing paintings. Kelvin, wattage recommendations? 

Based on the details provided, we might recommend the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) product. This product is designed to be compliant with the D50 standard, and could be a great option for your space.

Difference between FilmGrade and Centric Home A19 Bulbs

What is the difference between FilmGrade and Centric Home?

We can confirm that the FilmGrade™ Flicker-Free A19 LED Bulbs and the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulbs are the same product. As such, both items can be expected to offer the same benefits.

We do apologize for any confusion caused, as the product is shown on multiple pages for marketing purposes. This can be noted by the shared part number (4005.30) listed in the item description for both products.

Oil Painting Studio Lighting Recommendations

I am a professional Oil Painter, and I am looking for your recommendations on bulbs for my 4 softbox lighting kits (16-20 bulbs total). I have to paint at night while my kids are sleeping so it is essential that I have as close to perfect daylight as humanly possible, so if you would kindly suggest your best options I will order all of them.

​Our NorthLux A19 is one of the most popular products among our artists and studio customers who are after the best color rendition for daylight-calibrated color temperatures. I've included the link below:

You mention that you're after a lamp that is as "close to perfect daylight as humanly possible," and we're very confident that the 5000K and/or 6500K color options will meet your needs here. The one tricky thing, as I'm sure you are aware, is that "perfect daylight" can be challenging to define, as natural daylight conditions can change depending on the time of day, season, geography, and weather - not to mention the orientation of the windows and other natural lighting features in a studio space.

As such, we offer both 5000K and 6500K color options to allow our customers to decide. The 5000K color option more closely resembles a neutral, noon daytime light color, whereas the 6500K color matches the natural light that you would see from a north-facing window on a clear day. Both feature 95 CRI, which indicates that they will be a near-perfect match to natural daylight, but as I've described above, the definition of "natural daylight" is a bit different when choosing 5000K vs 6500K.

We do have a blog article going over the differences below, which might be helpful:

https://www.waveformlighting.com/art-painting/difference-between-5000k-and-6500k-bulbs

Our A19 lamps include a standard medium screw base and should be a quick and easy installation in your existing soft light boxes. Each lamp is approximately equal in brightness to a 60-watt incandescent bulb (but, of course, with daylight color calibration!)

Flicker-free Bulb for Color Rendition and Artwork

I'm looking for a flicker-free bulb that has good color rendition, for alertness and artwork. What do you recommend?

Though we, unfortunately, do not have 100W bulb products available at this time, we're happy to confirm that we sell many products that offer a high CRI which could be beneficial for artwork creation.

For example, our D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) product is flicker-free and offers a high CRI of 95+, as well as an R9 value of 80+.

This product is also designed to be compliant with the D50 CIE Standard, which may prove to be useful. For more information on D50, we have a terrific blog post on our website, which I have linked below.

What is D50 for graphic arts & printing?: https://www.waveformlighting.com/color-matching/what-is-d50-for-graphic-arts-printing

Are there any flicker-free floodlights?

Unfortunately, we do not currently sell any flicker-free floodlights aside from our realUV™ LED Flood Light product at this time.

However, based on the details provided, our NorthLux™ 95 CRI T5 LED Linear Light Fixtures might be of interest as an alternative. These integrated lighting fixtures can be easily mounted onto many surfaces, contains all electrical components within the housing, and are available in both the 5000K and 6500K color temperatures.

Difference between NorthLux and D50 A19 Bulbs

I ordered the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio - 1-Pack / 5000K and D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) - 1-Pack / E26 (North America). Are they the same product? 

Regarding the products mentioned, we can confirm that the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio and the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) are the same product.

We do apologize for any confusion caused as the product is shown on multiple pages for marketing purposes. This can be noted by the shared part number (4005.D50) listed in the item description for both products.

I have a new question about the aluminum channel for LED Flex Strip. How are the corner channels mounted? I only see the mountings pictured for the flat channel.

We're happy to confirm that the Aluminum Channel for the LED Flex Strip product arrives with installation accessories, including ten mounting brackets and screws that can be used for affixing the channels upon a surface.

Centric Daylight A19 LED Bulbs for Bathroom Lighting

Are your Centric Daylight bulbs appropriate for a bathroom? I want to make sure that the humidity won't damage them. 

We're happy to confirm that the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulbs are suitable for damp environments, such as bathrooms.

However, please be advised that the product is not insulated against direct contact with moisture greater than humidity.

Does Feiss Issen 2-Light Flush Mount Fixture compatible with your A19 Bulbs? 

I currently have 8 Sylvania 21942 - FO25/741/ECO T8 Fluorescent lights in my L-shaped kitchen and each leg of the L is approximately 12'x7'. Each of these bulbs is 25W, 4100K, and 1755 lumens. I'm switching out the old fixtures and replacing them with 3 Feiss Issen 2-Light Flush Mount FM504SN. It has a closed round glass shade: D: 13.5" H: 1.25" and uses 60W A19 medium incandescent bulbs. I'd like to use LEDs instead, being mindful that the light is closed, not open. Any suggestions?

Based on our review of the Feiss Issen 2-Light Flush Mount product, it appears that while otherwise compatible, the fixture is completely enclosed.

As our A19 bulbs would require a moderate amount of airflow for heat dissipation, these may not be the ideal fixtures for use with our A19 products.

However, we would be more than happy to review any other light fixtures for product compatibility.

Does the Avian A19 LED Bulb need to be installed closely to birds for full-spectrum light benefits?

Does this light bulb need to be right over my conure cage and perching area are can it be used in the light fixture in the ceiling in the room he is in? I saw some other lights have to be really close to birds for them to get the benefits of the full spectrum light- but they also can cause burning to the bird's eyes from being close.

We do not have a specific requirement as far as distance away, but in general, we recommend installing a larger quantity of bulbs located far away, rather than a fewer quantity installed very close.

The overall goal would be to replicate natural daylight, which actually "rains down" from a very wide 180-degree dome (i.e. the sky).

LED Light Bulbs Equivalent to Natural Sun/Daylight

Could you please recommend which bulbs should I purchase to have bright sun/day light? My apartment is very dark, and the buildings around block natural sunlight. I need to have the light turned on during the day and would like to have an equivalent of natural sun/daylight. 

Please see below for our CENTRIC DAYLIGHT A19 LED bulb. These lamps can be used in any standard screw-in lamp socket and will provide you with bright daylight color for your space.

We would also recommend using our lumen estimation calculator to determine how much light you will need to ensure proper brightness:

https://www.waveformlighting.com/lumen-calculator

Difference between Centric Daylight and NorthLux Bulbs?

What is the difference (for an end consumer) between the Centric Daylight and NorthLux 95 bulbs? I am looking at 6500k bulbs.

We're happy to confirm that the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb and NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio products are extremely similar.

The primary difference comes from the D65 standard which the NorthLux A19 bulb is designed to align with. D65 is a global industry standard for lighting products, which some customers who work with photography or art production might find great benefit in. However, the majority of customers may not notice a difference between the two products at all.

For more information regarding the D65 standard, there is a great article on our website that might prove to be useful: https://www.waveformlighting.com/color-matching/what-is-d65-and-what-is-it-used-for

Are your LED Bulbs compatible with American Fluorescent Fixtures?

The light fixture I have for this size tube is made by American Fluorescent. Just wondering if this fixture might have proven to be compatible with your light since the list was made.

We're happy to confirm that our Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential products is compatible with enclosed light fixtures. However, our other A19 bulbs will require a moderate amount of airflow and heat dissipation which the enclosed fixture may be unable to provide.

We can also confirm that our T8 LED tube lights are compatible with existing T8 fixtures. However, our T8 LED tube lights may not be compatible with the ballasts within all fixtures. Below is a link that contains the list of compatible ballasts.

Tested ballasts: https://www.waveformlighting.com/files/CD4020.txt

If the ballasts are not compatible, there are alternative installation methods described within the product specification sheet, such as ballast bypass, which could prove to be valuable.

I was more interested in the A19 Bulbs, and I see in your description that they cannot be used in enclosed fixtures (Centric Daylight, NorthLuz, and D50).

Unfortunately, each of the products listed requires some amount of enclosure airflow so that the heat generated by the bulb can dissipate.

Without adequate heat dissipation, the electronic components within the LED products can be prone to error.

Dimmable T8 LED Tube Lights for Art Studio Lighting

I am interested in the CRI 95 5000K Northlux LED Tube, but I need a dimmable one if possible. 

Unfortunately, our T8 LED tube light products are not compatible with dimmers.

However, our LED Strip Light products are compatible with dimmers and could prove to be a valuable alternative depending on your installation.

I decided to, for now, purchase several packs of the 4000K CRI 95 Centric Daylight Bulbs. What is the R rating for these bulbs?

We have attached the photometric report for the 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulbs below, which lists the R values.

Photometric report link: https://www.waveformlighting.com/photometrics/TR_4005.40.pdf

What is meant by "enclosed fixture"? And why is this an issue?

You note that the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb is not suitable for use in an enclosure. Can you explain more about what you mean by an "enclosure" and why this is an issue? Is it a heat issue? I have a circular fixture with a 1/4" opening between the top and bottom plates and the center glass piece. Would this be OK?

Some of our products, including the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb, contain electrical hardware within the base of the bulbs which is heat sensitive. As such, these products are known to encounter issues when they have been installed within fixtures that do not allow for moderate airflow. 

For instance, a ceiling fixture that is completely enclosed by the glass would not allow for the heat generated by the bulb to dissipate, whereas a wall sconce with an opening would more easily allow for sufficient heat dissipation.

Based on the description provided of the light fixture, you may not encounter heat issues as the fixture appears to allow for moderate airflow. ​

Recommended LED Light for SAD in a Basement Apartment Installation

I would like to get something for the basement apartment that is best for mental health during the dark winter in VT. I'm sorry, but I'm finding your website totally overwhelming with all the information. Could you just recommend something? Also, I was looking at the Centric series LED bulbs, but the two I saw said they were only 10W each. That seems really dim, especially for a dark basement apartment. 

Based on the details that were provided, there are a few products that we might recommend depending on the intended use of the space.

For use within general-purpose areas of the apartment, we might recommend the 3000K FilmGrade™ Flicker-Free A19 LED Bulb or the 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb.

For work areas, or artwork creation areas, we might recommend the 5000K option of the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb.

Each of these product options will offer the same high CRI, which measures how similar the light spectrum output of the bulbs is to natural sunlight. These products also feature a low flicker-rate. Products with a high flicker rate, such as fluorescent lights, can cause additional eye fatigue.

​However, in the event that these bulbs are not bright enough, or wind up being not to your preference, we are happy to offer a 30 day return policy. Simply let us know which products you would like to return, and we will issue a free return label.

Choosing LED Northlux vs Centric Daylight for Painting Studio

I have a question about choosing Northlux 95 CRI bulbs vs the Centric daylight full spectrum bulbs either in 5000K. 

I am using these lights in a painting studio so I'm looking for high as possible color quality as can be. I also read your site said if I care more about a CRI I should use a fluorescent fixture choosing one of those bulbs above which fixture below would suggest for my situation and how many fixtures of each would you suggest to obtain the ideal illuminated result in the painting studio? Further information to give more background in my situation. I have a 12" x 16" space with 15-foot ceilings and I will be making work on both 12-foot walls as well as one 16-foot wall. 

The primary difference between the 5000K A19 bulbs can be found in the CIE D50 standard which the NorthLux product was designed to be compliant with. This is an international color standard which many find value in, due to the low amount of variability in light spectrum output across compliant products.

Here is a great blog post from our website which explains this standard further, which might be helpful: https://www.waveformlighting.com/color-matching/what-is-d50-for-graphic-arts-printing

However, in the event that you would prefer to utilize a T8 LED tube light fixture, I am happy to confirm that both fixtures provided appear to be compatible with our products.

The two LED tube light products that I recommend for your studio are the D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000), and the NorthLux™ 95 CRI T8 LED Tube for Art & Studio. The D50 5000K option has a higher R9 rating than the NorthLux (95 vs 91), which could be beneficial for working with color.

Based on my calculations using our lumen estimation calculator, it appears that your space would benefit from 15,981 total lumens. As each of the T8 LED tube lights emits 1800 lumens, we recommend 9 lamps in order to sufficiently illuminate the space.

Difference between the NorthLux and D50

I am interested in purchasing some light bulbs for a fixture being installed in my studio to supplement our North light window into the evening hours. I am looking at the NorthLux and D50 bulbs and wondering what the distinctions between the two bulbs are. It seems the NorthLux is best suited to our needs, however, our electrician is recommending the D50. 

Our NorthLux products are offered in both 5000K and 6500K. The 6500K color option is likely to be an excellent match for the natural light you currently have coming in from your north-facing window. Some visual artists and other professionals do prefer 5000K as it provides a bit less blue and is a more neutral color point.

For additional insights into the difference between these two color temperatures, please see below:

https://www.waveformlighting.com/art-painting/difference-between-5000k-and-6500k-bulbs

Our NorthLux products in 5000K are actually the same product as the D50, and the products are listed on multiple product pages for marketing purposes. We do apologize for any confusion caused!

NorthLux vs. D50 for Oil Painting Studio

I'm an oil painter based in Finland (Europe). I'm looking for a high CRI true-to-natural light lighting solution and am very interested in your NorthLux product range. The thing is, your NorthLux bulbs don't seem to come in E27, and I'm unsure whether I can use them in my Andoer softbox-fixtures. The only product that seems to come close is the D50 colour matching bulb. How close is this to the NorthLux bulb, and would you recommend it for a painter's studio as the next best thing? 

Our high CRI daylight bulbs sound like a great fit for your needs!

Our E27 D50, CENTRIC DAYLIGHT and NorthLux A19 lamps all feature the same 95 CRI and spectrum, and are listed on different product pages for marketing purposes. We do apologize for any confusion caused!

​The part numbers 4007.50 or 4007.65 will correspond to the 5000K and 6500K color variants that are available.

​Below is the link to the CENTRIC DAYLIGHT A19 page from which you can purchase both color options directly:

Difference in perceived brightness between A19 and BR30 LED Bulbs

Could you tell me if there is a difference in the perceived brightness, by beamspread, etc between the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio and the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio? 

Due to the 120 degree beam angle of the NorthLux™ BR30 bulbs, these products would indeed appear to emit a brighter and more focused light than the NorthLux™ A19 bulbs, even though both products technically offer the same 800 lumen output.

That being said, we are also happy to offer a 30 day return policy in the event that you would like to purchase both items in order to make a direct product comparison.

FilmGrade A19 LED Bulb 3000K Spectrum Chart

Can you please send me the Spectrum Chart PDF for this item: FilmGrade™ Flicker-Free A19 LED Bulb

Below is a link to the photometric report for the 3200K FilmGrade™ Flicker-Free A19 LED Bulb product (PN 4005.30).

Link: https://www.waveformlighting.com/photometrics/TR_4005.30.pdf

Do you all have plans to make any G16.5 bulbs or other common household bulbs?

Unfortunately, I am not aware of any plans to introduce other bulb standards, such as the G16.5, to our store at this time.

I’m confused about the PDF. It seems to be the exact same pdf as the centric 3000K. Is there no difference on the spectrum and CRI levels? Specifically looking at R9...

The identical data is due to the fact that the 3000K FilmGrade™ Flicker-Free A19 LED Bulb product is identical to the 3000K CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb. This can be noted by the shared part number of PN 4005.30. As such, while there may be extremely small differences between individual bulbs, the performance can be expected to be the same for both items.

We do apologize for any confusion which may have arisen by this, as these products are displayed on multiple pages for marketing purposes.

Is there a Flicker-Free BR30 option? I guess the idea is 6% is close enough. 

We can confirm that our BR30 bulbs are not currently flicker-free, though they do offer a lower flicker rate than many similar products on the market.

Flicker-free LED lights for Golf Simulator System

We plan to install a Uneekor EyeXO golf simulator with 2 high-speed cameras. Uneekor has recommended I install at least 8 15-watt or higher non-flickering LED track lights to provide adequate lighting to avoid blurring of the images during the golf swing. 

We don't currently have any track light fixtures, but you may want to consider several of our flicker-free lighting options to ensure that your golf simulator system is able to accurately capture high-speed images.

Our A19 products are rated flicker-free and may be the easiest product to install and set up, as it is a standard screw-in light bulb that can be used in a standard lamp fixture. Please see below for the product link:

How many of these installed in track lighting fixtures would be necessary to provide adequate lighting to capture the high speed images? The picture in the Optics attachment on page 10 shows 3 track lighting fixtures with 11 lights distributed among them.

It's a bit difficult to provide a definitive answer for brightness requirements, as this would depend on the camera system and the various light sensors used in the golf simulator.

One way to do a comparison against their recommendation is to compare lamp power. Our LED lamps are 10 watt lamps, so to achieve the same power level as the 8x 15 watt lamp recommendation, you will need at least 12 lamps to reach the same amount of power (8 lamps x 15 watts per lamp = 120 watts).

However, since our lamps are omni-directional, you may not see as much perceived brightness directed towards the golfer, compared to the track light lamps which tend to be more directional. As such, it may be beneficial to increase the power budget further to ensure sufficient brightness.

We would perhaps recommend testing and taking advantage of our free returns policy. If for whatever reason you find that the LED bulbs are not going to work for your project, we would be more than happy to pay for return shipping and offer a full refund. 

Do I want the A19 in 6000K?

Both the 6500K and 5000K should work fine for your needs, as both are calibrated to natural daylight and your camera system should have these calibrations built in. The color temperatures correspond, roughly, to north-facing daylight for 6500K, and direct noon sun for 5000K.​Both options offer 95 CRI and flicker-free light output and therefore should serve well for the application.

High CRI 93 LED Lighting for Residential

I am interested in bulbs with at least a 93 CRI. I see that you sell them. I would like to know what would be the best bulb for my family. The new bulbs sold in stores that are supposedly 60 Watts are not bright enough. What would be recommended and why is that your choice? 

Our 95+ CRI lamps sound like a great fit for you and your family. Our most popular option for residential installations is our CENTRIC HOME A19 lamps, which are available in a 60 watt equivalent brightness. The 2700K and 3000K color options are both excellent options for home use.

Below is the product page for the CENTRIC HOME A19 bulbs:

For more information concerning color temperature, please see our article below:

https://www.waveformlighting.com/home-residential/choosing-between-2700k-and-3000k

The new bulbs sold in stores that are supposedly 60 Watts are not bright enough. I see you recommended your Centric Home A19 bulbs. Does this seem brighter than the 60 W bulbs I could buy at the store and if so, is that due to the CRI? Why is that your choice to recommend? How many bulbs come in 1 pack?  

The 95 CRI bulbs will most likely provide the same amount of perceived brightness as an 80 CRI bulb that also emits the same amount of brightness (i.e. 60 watts). However, because the CRI is higher, a lower amount of brightness may be sufficient for task-oriented activities, as the improved color clarity may counteract the need for additional brightness.

​We unfortunately do not have any higher brightness bulbs so this would our best recommendation. Generally, we recommend increasing the number of lamps, rather than the brightness of any individual bulb, as this can help reduce glare and improve the light distribution in a space.

The 1-pack refers to 1 bulb.

​We would perhaps recommend testing and taking advantage of our free returns policy. If for whatever reason you find that the LED bulbs are not going to work for your project, we would be more than happy to pay for return shipping and offer a full refund. 

High CRI LED lighting for Photographic Printmaking

I am a professional printmaker for photographers who sell their work in galleries. I also produce prints for museum exhibits and corporate photography installations. I am building a new print-making studio. I would like high CRI lighting for my print viewing/color-correcting area. I need 5000K Hi CRI (95 or higher) for color correcting as well as 2700K and 3000K high CRI to view prints for how they will look under gallery or museum lighting. I would prefer to have one light source to be able to produce all three color temperatures. Each color temperature would be used one at a time. Which of your products would work best for my application?

Our high CRI LED lighting offerings sound like a great fit for both the color viewing (D50 / 5000K) as well as gallery/museum lighting conditions (2700K/3000K).

​Unfortunately, we do not offer any products that feature the ability to switch between those color points, so we would instead recommend installing separate lamps for each of the color points needed.

​For the D50 / 5000K color point, our line of NorthLux or D50 products will work well for your needs. For example, please see below for our A19, T8 lamp or T5 fixture options:

Our 2700K and 3000K are a bit more limited in form factors. Below is our A19 and BR30 lamp option:

If you can let us know a bit more about the lighting installation in terms of fixtures and location, we'd be glad to assist with some additional recommendations and guidance!

Will your T-8 NorthLux 95 CRI LED tubes operate with a dimmable ballast allowing me to dim the output and still maintain the same color temperature and color rendering index?

Unfortunately our T8 LED lamps are not dimmable, and will not work with a dimmable ballast. Sorry for the bad news!

Do BR30 and A19 bulbs dim properly with older-style dimmers that adjust voltage?

Do BR30 and A19 bulbs dim properly with older-style dimmers that adjust voltage? Do the bulbs make a humming noise when dimmed with the older-style dimmers?

We can confirm that our A19 and BR30 lamps are designed for use with modern phase dimmers. However, they are not designed for use with older dimmers such as rheostat dimmers.

As such, these products may not be compatible with the dimmers that you have installed. We might recommend reaching out to a local lighting expert for further specialized instruction regarding compatibility.

LED Lighting Suggestion for Photography

I am looking for an equivalent of 50 W bulb D65 to screw in (for a dim room lighting 8'x13'x8'), another one around 75-80 W D50 also to screw into my desk lamp to hard proof my prints, and another one of around 3700K also for prints evaluation. 

While we, unfortunately, do not offer D65 bulbs that would into traditional lamp fixtures, we do offer the D65 ABSOLUTE SERIES™ LED Linear Module product, which might be an alternative depending on your installation.

We also offer the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) product, as well as the D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000) product, which may also be worth consideration. However, these D50 calibrated products are currently only available in the 5000K color temperature.

If I understand correctly, your lights are “full spectrum” eg 6500 K seems to be not far away from D65. Would it be wrong, if my display is on D65, to use one of your bulbs for my ambient light? centric? Northlux? Ultrahigh 95 jewelry? Avian? I do not see any difference between them except that one of them is Flickr-free but same price. 

If this does not work (800 lm could be too bright), and those LED are not dimmable without any further installation, another option could be bias lighting. I have an NEC PA302W: it is a 27.1 x 18 monitor on a stand. Should I use the sidewinder reels? How many? I understand a portion of 24” horizontally, and half of a foot on both sides with 1 reel. Will it be OK like that? Will it be necessary to use a dimmer? I have a black curtain on my window, so it is pretty dark when the door is closed.

We're happy to confirm that the majority of our products are indeed a full spectrum.

Further, we can also confirm many of our products are quite similar. If you have a specific set of products in mind to compare, I would be more than happy to explain the differences between them.

Regarding bias lighting, the Sidewinder™ LED Flex Strip for D65 Bias Lighting product could be a great option for your space.

Based on the measurements provided of your monitor, we recommend two 3.2 ft (1 meter) units of the Sidewinder™ LED Flex Strip product to wrap the back of the display in lighting, depending on the layout that you choose for installation.

This product can also be paired with a dimmer, in the event the level of the emitted light is too bright for all use cases. We recommend pairing this product with the 24V DC power supply, as well as the FilmGrade™ Flicker-Free LED Dimmer product.

I am looking for a D65 bulb for the ceiling but that will be probably too bright as ambient light and this will send some light directly to my computer screen. Moreover, they are non-dimmable or necessitate an installation too complex for me. Anyway, there is a bulb over there, and I will choose one which is adapted; I am a photographer. Flicker-free? 

1. What is the difference between the lights?

Based on the details that have been provided of your space, the A19 bulb that I would primarily recommend would be the 6500K NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product, which was designed to be D65 Illuminant-compliant. This means that the product strictly aligns with a global standard designed for color work. However, please note that while many of our A19 bulbs are flicker-free, none of the A19 bulbs previously mentioned are dimmable. As such, these products may not be beneficial for your space.

That being said, we can confirm that some products are indeed the same item, such as the CENTRIC DAYLIGHT™ A19, as well as the Ultra High 95 CRI A19 bulb. This can be noted by the shared product number, listed as PN 4005.65. This is also true for some other products that we offer. 

​We do apologize for any confusion which may have arisen, as these products appear on multiple pages for marketing purposes.

2. How to connect the 2 strips: daisy chain? connectors?

We're happy to confirm that the Sidewinder™ LED Flex Strip product is designed with plugs on each end of the reel, which allows for the product to be daisy-chained together without additional hardware. I have attached a photo of the product, which may prove to be helpful. That being said, please note that a compatible 24V DC power supply, such as our FilmGrade™ DC Power Supply for LED Strip product, would still be required.

3. What do you mean about “depending on the layout you choose for the installation”?

We do apologize for any confusion caused by my wording. Some bias lighting is installed as one horizontal strip behind the monitor. If this was the installation that you would prefer, we might recommend one unit of the Sidewinder product.

Alternatively, we have seen other bias lighting installed as three strips of lighting. Two vertical strips are applied to the back of the monitor parallel to the sides, and one horizontal strip is applied to the back of the monitor which runs parallel to the top. If this is the installation that you would prefer, we might recommend two units of the Sidewinder product.

Do you have a dimmable A19 LED Bulb?

I don't see any Dimmable LED bulbs on here. Is that on purpose? I'd really like another good option for good dimmable bulbs. CREE bulbs handle dimming very well, but the color is honestly not very good for their standard A19 60w 2700k bulb (even if it says it is CRI 90+). I really loved Hyper ikon's 93 CRI* 3000K bulbs but they supposedly only like ELV dimmers, not PWM. You guys sell a dimmable filament-type bulb which I have not seen before so I'd like to try that in my clear pendant lights instead of the current incandescents. And if those work well, I'd like normal bulbs from you guys but all my lights are on dimmers.

​You are correct that the only dimmable A19 bulb we currently offer is our filament-style lamp. We'll be sure to share your feedback with our product team and do hope we may be able to offer dimmability in our other A19 products in the near future.

Do keep in mind that we offer a 30-day free returns policy, so should you have any concerns or issues with the filament-style A19 lamps, we'll gladly pay for return shipping and provide a full refund.

LED Lighting Suggestion for Small Townhome of 1200 sq ft

Could you suggest a type of LED lighting for a small townhome ~ 1200 sq ft? I have 9 led lights in my downstairs and the room takes a pink/peach hue. I have white walls and want everything crisp, but cannot find a good brand or light.

Our high CRI LED lights should be a great fit for your home.

The first step in determining your lighting needs would be to understand the amount of brightness and the number of lights needed. Based on the square footage provided, we ran some quick calculations using our lumen estimation calculator (https://www.waveformlighting.com/lumen-calculator) which suggests approximately 26,000 lumens as your target brightness level.

​We would further recommend a 3000K color temperature which will provide your residential space with a comfortable but crisp white, light.

Does Full Spectrum Flicker-Free A19 LED Bulb Emit High Levels of EMF?

LED lights are known to emit high levels of EMFs and also produce dirty electricity. Can you tell me more about this regarding these light bulbs? https://store.waveformlighting.com/products/centric-daylight-full-spectrum-flicker-free-a19-10w-led-bulb

We do not have any EMF measurements on our lighting products at this time. We can verify that they are flicker-free, however, with a flicker % of less than 2%.

So you mean to tell me someone can call something "flicker free" even though it still has a flicker?

The official threshold for our flicker-free products is 2%. In actual tests, our flicker % is at 0%. For example, see below:

https://www.waveformlighting.com/photometrics/TR_4005.40.pdf

LED Lights for Textile-Dye Color Matching

I am looking for a lightbulb that will give me the most accurate color reading in my fabric restoration work. I use dyes to restore color loss on carpets and rugs and need to be able to match perfectly the color of the original to the spot I am touching up. What would be the best product for this?

We recommend the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) product. This product features a high CRI, is flicker-free, and is D50 calibrated for color-critical work which might be valuable for your purposes. We also have a great blog post on our website regarding D50, which I have linked to below in the event that it is useful.

What is D50 for graphic arts & printing?: https://www.waveformlighting.com/color-matching/what-is-d50-for-graphic-arts-printing

​However, please know that offer a 30 day return policy. In the event that one product winds up being preferable over another, simply let us know and we would be happy to issue a free return label for your refund. 

Difference between D50 and Centric Daylight

What is the difference between the D50 and the Centric Daylight?

While both the D50 and CENTRIC DAYLIGHT products offer a 5000K color temperature, the D50 products are calibrated to a specific ISO color point for color viewing applications. For more information, please see below:

​https://www.waveformlighting.com/color-matching/what-is-d50-for-graphic-arts-printing

D50 or 5000K LED Lights with Best CRI for Color Creating and Matching

I'm a colorist, creating foundation shades ( makeup) I was looking for the best light to work with, and I thought the D50 would be perfect I notice Centric Daylight has a better R9 ( 100%) compared to the D50 ( 92%). Also, the Centrix are Flicker free so it would be healthier right? I'm facing north and I have Large Windows Could you tell me which bulb should I get? It would be great on your website to have a Graphic comparing all the light and the data! PS: I wanted to tell you that all the blogs regarding, Kelvin, CRI, UV, and other Questions are so Interesting! 

Based on the details which you have provided, we might recommend the 5000K NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product, due to the higher R9 value (listed as 94 in our latest photometric report), which could be very valuable for the color work that you mentioned.

However, please know that we also offer a 30 day return policy. In the event that one product winds up being preferable over the other, we will gladly issue a return label for a refund.

Do you have an E27 bulb with D50 and very high CRI 99?

I need a light with very high color reproduction for visual arts applications (slide reproduction = high quality 'scanning' with a DSLR camera). What would be your recommendation?

We would recommend our CENTRIC DAYLIGHT E27 5000K A19 lamp for your needs.

​The 5000K color temperature will meet the D50 chromaticity requirements and the lamp has a color rendering index of 95+.

Comparing the two '5000K Photometric Reports' I can't find any difference between the D50 5000K bulb and the centric daylight full spectrum bulb 5000K you mentioned. Are these two bulbs identic?

We do list our products on multiple product pages, and you are correct that the E27 CENTRIC DAYLIGHT 5000K is the same product as the E27 D50 product. You can confirm this via the part number indicated for both, which are 4007.50.

Is there no bulb version with E27 base 5000K D50 with Absolute Series LEDs CRI 99 available to get a substantial improvement in the reproduction of R12? Is such a bulb with Absolute Series LEDs and higher CRI under development?

Unfortunately, we do not have any lamp products with our ABSOLUTE SERIES LEDs at this time. You are absolutely right that this would allow us to see improvements across the board in terms of color rendering, including R12, and do hope to be able to offer this in the near future!

Will it damage the Centric Home Flicker-Free A19 bulbs using a dimmable power supply?

I bought a few Centric Home A19 bulbs from you. I was looking for a power supply for these bulbs, and I bought a few dimmable ones that can go 5%, 30% & 100% on light intensity. Will that damage my bulbs?

The CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulbs from your order is unfortunately not compatible with dimmer products.

However, we do offer other products which are compatible with dimmers, such as the Full Spectrum E26 BR30 LED Bulbs.

ABSOLUTE SERIES™ LED Flexible Strip for Photographic System for Meat Product Image Analysis

We would like a set of lights with a more accurate representation of daylight, and ABSOLUTE SERIES™ LED Flexible Strip - 99 CRI seems the best option. We would like to mount it in a black box, so we need to standardize lumens in the whole box, without reflections, is it possible to use these LEDS flexing them in a circle of around 60 cm diameter? If not, we should go for the bulbs, in this case, which one of them would you recommend to us? 

Our ABSOLUTE SERIES LED strip lights indeed sound like a great fit, as they will indeed provide you with the most accurate representation of natural daylight.

​The one challenge I foresee with the product is that while it is flexible in an up/down direction, it cannot be made to curve in a left/right direction. As such, creating a circular design with the product would be quite challenging.

​If you can work with a polygonal shape that approximates a circle, such as a polygon with 8 sides or more, you may want to consider using the LED strips in short, straight runs joined together using a connector such as our PN 3071.

For similar lighting quality, we would perhaps suggest our NorthLux A19 lamps, which can be found at the link below:

About the power supply, since we are in Europe, so maybe is better if we buy a European plug, or do you have this option? I understand we need a 120W 12V 10A output. So the female barrel jack and one of the strip-to-strip connection is enough to make the connection, is it right?

You can certainly utilize a European version of the 12-volt power supply. As you mention, the primary requirements are electrical (120 watts, 12V/10A) and to ensure that the output plug is compatible with the ABSOLUTE SERIES LED strip light barrel jack DC connector (included on both ends).​Our North American version can also be used in Spain but will require a plug adapter for the wall outlet ​which you will need to purchase from a third party locally.

As mentioned above, the ABSOLUTE SERIES LED strip light includes the DC connector pre-installed on both ends of the reel. As such, PN 7094 is likely unnecessary.

PN 3071 is the correct accessory to join the cut sections back together at any angle needed.

Are there any known health hazards using red phosphors in the bulbs?

I am outfitting my home with waveform-led bulbs. I was wondering if your bulbs give off UV rays to the occupants. Are there any known health hazards with using red phosphors in the bulbs? I am buying PN 4011.40, PN 4002.30 PN 4011.30 I am hoping that all your lights have reduced blue spectrum and are safer than the typical LEDs at hardware stores. I know that your lights carry the CE rating but are not UL listing. 

Our bulbs do not emit any UV rays, and all emitted electromagnetic waves are longer than 430 nanometers.​There are no known health hazards with red phosphor wavelengths as their peak wavelengths are at 630 nanometers or longer.

These photometric properties apply to all of the PN 4011 and 4002 product lines. For reduced blue light output, we would generally recommend high CRI and low color temperature lamps as they will generally offer the best mix of wavelengths to reduce blue light exposure.

LED Home Office Lighting: Best Color Temperature that Mimic Sunlight

I am trying to mimic "sunlight" in my small home office now that the days are getting shorter. The closest thing to my desired lighting that I have experienced is dental overhead lights. I recently purchased a FilmGrade A19 LED bulb, but it felt a bit cool to me. I realize that natural daylight sits in the 5600K to 6500K color range. 

1) Do you have suggestions for which of your A19 or BR30 bulbs may best fit my use case? 

2) Am I always going to find "natural daylight" options a bit too cool? Would 4000K or 5000K offer a better experience? 

Getting the correct color temperature is indeed a challenge!

​You are correct that the 5000K to 6500K range is generally considered a good match for natural daylight. 4000K is also a nice option, and you may find some useful information on our blog post here.

​One thing to keep in mind that oftentimes, natural daylight color temperatures can appear a bit blue or stark when you do not have enough brightness overall. To that end, if you have any information on the total square footage being illuminated, we may be able to provide some additional recommendations on the quantity of lamps needed to provide sufficient brightness at that color temperature.

We would perhaps recommend taking advantage of our free returns policy to test and compare the various color temperature options and lamp quantities. Once you've made your mind, just let us know and we'd be glad to pay for return shipping and refund you for any returned items. 

6500K Flicker-free Lighting for Art Capture, Color Correction and Fine art Printing

I perform art to capture, color correction, and fine art printing. I am using Ikan Lyra LEDs at this time but not so happy with their results. They are okay, but I am looking for 6500K lighting, also flicker-free. I see you have bulbs and strips. 

We suspect that the primary reason for the difficulty in judging color differences is due to an incomplete spectrum emitted by the Ikan product. Specifically, this will likely be reflected in a low CRI value, possibly in the 80-90 range. (You may also want to look into the R9 value, which provides even more data about red color rendering in particular).

As a starting point, we would recommend experimenting with a few of our 95 CRI products. Here are the A19 bulbs which are daylight calibrated to D50 (5000K) and D65 (6500K) with a 95 CRI rating and would be a great starting point for your tests:

If you would like to consider our LED strip lights, we would recommend our FilmGrade LED strip lights which are offered in both 5600K and 6500K:

Our 5000K LED strip lights (also in 95 CRI) are listed under our retail & commercial section:

Installing the LED strip lights will require a bit of additional assembly and installation work. For additional guidance, we recommend referencing our layout maps which can be found at the link below:

https://www.waveformlighting.com/layoutmaps

​Finally, ​we would recommend taking advantage of our returns policy to test out several of the color temperature options and determine if our products do indeed offer an improvement over your current setup. The full policy can be found below:

Do you have BR30 bulbs in 2700K Color Temperature?

Do you not offer the BR30 bulbs in 2700K color temps? The data sheet seems to indicate that you do.

Unfortunately, we no longer offer the BR30 bulbs in the 2700K color temperature.

I am ready to purchase your 3000K flood lights and regular A19 bulbs to retrofit all the existing fixtures in my home. How tightly controlled are your color temperature and CRI values for each of your bulbs, and can I select a particular binning range given that my order will be over $1000?

At Waveform Lighting, we take great care in ensuring the consistency of the products that we offer. This process includes having a very narrow tolerance for variations in the quality of light being emitted by our lighting products.

All of our products are manufactured using single-bin production. Even so, we would be more than happy to provide you with an order containing items originating from the same production batch to be extra sure of color consistency.

Ultra High 95 CRI A19 5W LED vs CENTRIC HOME A19 10W LED Bulb

I need a single bulb that's around 400 lumens and 2700K, so I was looking at your Ultra High 95 CRI A19 5W LED. However, the description does NOT mention that it is flicker-free nor does it mention that it's full-spectrum (while your CENTRIC HOME A19 10W LED Bulb does mention these traits). Is the 5W a lower-quality product? Or is it just fewer lumens?

I can confirm that the 2700K Ultra High 95 CRI A19 5W LED Filament Bulb features the same high CRI of 95+ as the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb. As such, both products are considered to be full-spectrum.

However, the Ultra High 95 CRI A19 bulb does not offer the same flicker-free performance as the CENTRIC HOME™ bulbs. The flicker-rate of the Ultra High 95 CRI A19 bulb is similar to that of traditional incandescent bulbs.

The benefits offered by the Ultra High 95 CRI A19 bulbs can be found in the warmer color temperatures available, as well as the compatibility with dimmers. In contrast, the CENTRIC HOME™ is not dimmable.

LED Lights for Art Painting Studio

We have a studio with existing lighting. This is an artists painting studio so color is paramount and we have never got it right. We would like you to recommend a lighting scheme or bulbs to put in our existing lighting to improve the painting light quality.

Most household lamps have a low color temperature which can be nice and relaxing for a typical residential installation, but for a color-critical application such as yours, having a daylight-calibrated color temperature bulb is definitely crucial.

All of our NorthLux products are daylight-calibrated and will offer a nice approximation of natural daylight, which will help tremendously in being able to accurately see colors in artwork creation.

Since it sounds like you do not have any specific fixtures already in place, you do have quite a bit of flexibility in terms of installation location and types of lamps.

​If you have an table or desk lamps, we would perhaps recommend our NorthLux A19 lamps. Alternatively, if you would like to mount some additional lighting onto a ceiling beam or even a shelf, we would recommend our NorthLux T5 fixtures which may be a great option for you.

Are BR30 Bulbs Compatible with a Legrand Tru-Universal Dimmer?

I have a new job that's interested in your products. I remember the last time, I returned some products because they weren't dimming correctly. Can you confirm that the BR30s are compatible with a Legrand Tru-Universal dimmer and that they don't buzz audibly when dimmed?

We, unfortunately, do not have any test data on that particular dimmer model this time.

In the meantime, if you're in a rush to decide on the installation, we would recommend purchasing a sample set of bulbs to test and see if they work well and provide the lighting performance you are looking for. If it doesn't work out, we'd be glad to pay for return shipping and provide a full refund.

I thought the A19s used to be dimmable. Did that change?

The A19 filament bulbs are dimmable, but the 10-watt A19 bulbs are not. Please see below for the dimmable A19 filament bulbs:

LED Bulbs for Art Studio with Track Lighting System Compatibility and E26 Base Standard

I'm trying to choose between 2 of your wonderful products to light my art studio. I have 2 rows of track lights with E26 Edison sockets. I'm not sure if I should get the regular bulb (NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio) or the floodlight version (NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio). 

We can confirm that both our NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio and NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio bulbs are compatible with track lighting systems that utilize the standard E26 base.

Regarding the differences between the two products, the BR30 does offer a narrower beam angle than the A19 bulb. Other customers have let us know that this feature has been beneficial for their track lighting fixtures.

Lighting for Small Artist Studio Space

I need directions to set up a painting area in the garage. I am looking at the NorthLux lighting CRI 95 or above, around 7000 Lumens and 4,000-6,000K. The area will be around 10 x 8; the ceiling and outside wall is white, and the rest is concrete. The ceiling hight is 7' with 5' deep as my space is under a bulkhead for furnace vents. I want lighting to extend to area approximately 7/8' deep. Could you present me one or two proposed diagrams showing light placement? What is the height of your linear fixture?

Since it sounds like your space currently does not have any existing fixtures, that gives us the maximum flexibility in terms of installation and lamp type options, which is great to hear.

I would recommend our T5 linear fixture at this point, given that it will provide you with all of the necessary housing and mounting accessories without needing to buy any separate components such as a track light tracks and heads for a track light system.

To achieve the 7000 lumen target, you will want one of the following (or a combination of the following):

Unfortunately we're not equipped with any interior design software, so I'm unable to create any layout diagrams showing light placement, but if you have a rough sketch of the space along with some input on where you think the lights can be placed and installed from a practical standpoint, we would be more than happy to offer some additional input.

Generally, you will want to space the lights out as much as possible in order to prevent any excess shadows or hotspots / dark areas. If you will be performing most of your work in one specific area, in addition to the fixtures, you may also want to consider installing a few A19 lamps for localized task lighting:

The height of the T5 linear fixture is approximately 1.4 inches.

Difference between NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio and CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb.

I'm intending to purchase 6500K lighting of either NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio (4005.D65) or your CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb (4005.65). Can you please provide clarification regarding what further differences exist between these two products?

The primary difference between the NorthLux and the Centric Daylight is that the NorthLux has chromaticity points calibrated to D50 and D65 color points, for the 5000K and 6500K versions, respectively.​While the Centric Daylight also offers 95 CRI, the exact color point is not as precise.​If you are looking for a color point that matches ISO standards, we would recommend the NorthLux / D50 product lines.

High CRI 95+ 6500K E26 Color Grading room for editing, coloring matching, and finishing videos and still projects.

I'm looking for a lighting solution for a color grading room for editing, coloring matching, and finishing videos and still projects. In looking through your catalog, there appear to be several matches however they are not specifically listed under the color-matching category. Can you list every product that meets the above specs including non-E26 models?

Currently, the only E26 bulb that explicitly meets the D65 ISO color metric is the NorthLux 6500K A19 bulb. Please see below for the product link:

For non-E26, you may also be interested in our shop light and integrated fixture products, which are shown below:

Lightbulbs mimic the natural lighting in two regions: the Mediterranean and the British Isles.

I'm looking for lightbulbs that mimic the natural lighting in two regions: the Mediterranean and the British Isles.

Unfortunately, we don't have any bulbs that mimic a particular geographic region, but we do offer a CENTRIC DAYLIGHT A19 lamp that will work in standard light bulb sockets. The bulb offers three different color temperatures of 4000K, 5000K, and 6500K which should work well for your needs.

​Please see below and let us know if we can assist with anything else!

The difference between NorthLux and Centric Daylight Lamps in color-accurate lighting application.

What is the actual difference between the NorthLux and Centric Daylight lamps? Is it just that NorthLux has RedBoost and R9 >90 whereas Centric does not, and is only R9 >80, or is there more?

I'm an artist and looking for the most color-accurate lighting option to redo my studio and the entire house. I use 4" T8 tubes in the studio. Would the D50 5000K series render more accurate colors than the NorthLux 5000K? 

I see you have the Absolute Series as well, but it appears to only be available in strips. Do you, or will you have bulbs and tubes available in this series as well? 

The primary difference between the NorthLux and the Centric Daylight is that the NorthLux has chromaticity points calibrated to D50 and D65 color points, for the 5000K and 6500K versions, respectively. While the Centric Daylight also offers 95 CRI, the exact color point is not as precise.​The NorthLux and D50 series are the same product listed on multiple pages. If you are looking for a color point that matches ISO standards, we would recommend the NorthLux / D50 product lines.​Unfortunately we do not have any lamps with the 99 CRI Absolute Series at this time.

Are the NorthLux indeed R9 > 90?

The NorthLux A19 has an R9 value of 90+.

Also, I'm just curious why, if the NorthLux are more finely tuned, are they and the Centric Daylight bulbs the same price? 

We intend to consolidate production for both the CENTRIC DAYLIGHT and NorthLux lamps into a single part number in the future, such that all products would meet the same D50/D65 standard. As such, the pricing was set to the same price point preemptively as we expect to offer the same product in the future.

Are there plans to make any Absolute series bulbs, even just as 4' T8 tubes?

We do have a few plans for future product development in the ABSOLUTE SERIES, but unfortunately, there are no specifics on that yet.

Which of your lighting systems would you recommend for two months old lovebird?

I just got a new baby Lovebird that is about two months old. During the fall and winter, I want to give him adequate light that is as natural as possible so he can be happy and so his body can produce the nutrients it needs. Which of your lighting systems would you recommend? Do you have some kind of kit that would fit inside or above his cage that is simple to set up?

Currently, we are only able to offer individual bulbs for sale and we do not any have kits or complete solutions. If you have any existing lamps or fixtures, our lamps would be a great option to replace any old or burned out lamps, but if you are starting from scratch, you may want to check with some specialty pet supply sellers.

Below are the two lamps we currently offer:

What is the difference between Centric and NorthLux lights, since they each have 5000K and 6500K temperatures?

What is the difference between Centric and NorthLux lights, since they each have 5000K and 6500K temperatures? Do these have the same spectral output and are simply the same lamp but in different product families? For backlighting, 35mm slides when photographing (digitizing) which would be better, a 6500K from the Centric or Northlight groups, or the 5600K Filmgrade since it is supposed to match the camera sensor more closely?

For our A19 lamps, the CENTRIC DAYLIGHT products and NorthLux products both have 95 CRI, but have slightly different color point tolerances, with the latter being more precisely calibrated for color matching and viewing applications.

Specifically, the NorthLux 5000K meets the ISO D50 color viewing standard and may be a preferred option for your camera application. (The products are distinguished by their part numbers, which are PN 4005.50 and PN 4005.D50, respectively).

Regarding color correction, the closest match to D50 with our NorthLux product will suggest that few to no color corrections would be necessary because most camera systems will have the D50 color point likely pre-loaded as their calibration point.

Our FilmGrade A19 is another option that provides the same 95 CRI spectral quality, with a slightly higher blue component compared to 5000K. The 5600K color point is commonly used for photography and cinematography applications and is commonly chosen where ambient lighting conditions are also calibrated to a 5600K color environment.

Given the 95 CRI and high R9 values, the color spectrum of the NorthLux 5000K has sufficient coverage for all wavelengths that the camera sensors are calibrated to.

Are E26 Light Bulbs Interchangeable?

I have a fixture that came with a 14 watt E26 standard Medium base CFL bulb. Can I replace these with dimmable LED bulbs?

Based on the description provided, we believe that the following bulbs may work in your fixture, as both are dimmable and have a power consumption under 14 watts.

1. Ultra High 95 CRI E26 A19 5W LED Filament Bulb for Home & Residential

2. Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential

It shows you have two led bulbs for avian use. However, why the flood light version is dimmable, but the A19 bulb is not dimmable?

Would the A19 bulb blow up or fail if used on a dimmable circuit?At what distance from the birds should these bulbs be used?I always thought birds need UV radiation to produce vitamin D3. Do these bulbs not emit UV rays?

Unfortunately, due to the smaller size of the A19, we have not yet been able to incorporate the electronic components needed to achieve smooth and effective dimming. The A19 lamp cannot be used with any dimmers, even if the dimmer is set to 100% brightness.​We don't recommend placing the lamps too close to birds and maintaining at least a 1-foot distance away. We recommend placing 2-4 lamps per square foot to achieve sufficient coverage.​Our lamps do not contain any UV radiation - if you believe that additional UV exposure would be helpful, we would recommend locating a third-party source for dedicated UV bulbs.

Work light for textiles application used to view texture and detail, neutral to daylight color, and good for indoor use and in a desk lamp.

Can you recommend a work light that will be good for indoor use and in a desk lamp, preferably from neutral to daylight color? I am working with textiles, so not only is color important but being able to view texture and detail.

Is there a bulb you think would work? Or is there a range in color/wattage/bulb type coated or clear that I might have success with?

We would recommend our 5000K or 6500K NorthLux 95 CRI E26 A19 LED Bulb for Art & Studio products could be great options for your desk light, so long as your light fixture can accept A19 bulbs with the E26 base.

The 5000K color temperature would be closer to the 4000K mentioned, while offering a neutral daylight color point. Alternatively, the 6500K color temperature has a light output that is similar to full daylight.

A19 bulbs in semi-enclosed fixtures

The product page for the CENTRIC HOME™ A19 bulbs says they are not suitable for enclosed fixtures. Would they be OK to use in semi-enclosed fixtures? For example, I have some floor lamps with cone-shaped lampshades that surround the bulb. How about desk lamps with similar cone-shaped lampshades?

The 10 watt A19 lamps are not, as you correctly mention, not suitable for use in enclosed fixtures. Our definition of enclosed fixtures is defined as any fixture that completely seals off air flow from the ambient environment. The most commonly seen enclosed fixtures are those in residential ceiling fixtures, where a glass housing completely encloses the fixture base.

On the other hand, table and desk lamps that are partially enclosed will not present any issues with the enclosed fixture rating. Because these fixtures allow for sufficient free air flow, there are no concerns with respect to thermal damage and premature failure.

Best A19 bulbs for digitizing and photographing paintings and artwork?

I am a painter, and am considering using your NorthLux™ A19 bulbs to take photos of my artwork pieces to showcase on my website and other platforms. I am hopeful that these bulbs will reduce the amount of color correction needed post-capture. Are these the best bulbs for my needs?

Our NorthLux™ A19 lamps do indeed sound like a great option for your painting photography. These bulbs feature 95 CRI and daylight calibrated light output, which means they are perfect for image capture without any loss of color accuracy. Because the light source is fundamentally calibrated to full-spectrum daylight, there should not be any need for white balance or color correction adjustments.

The NorthLux™ A19 lamps are offered in 5000K and 6500K. Although both color temperatures can be considered to be daylight calibrated, 6500K will have a slightly blue hue in line with what you would see from a north-facing window, while 5000K will be more neutral, closer to direct sun. Here is an article going over some additional differences between the two color temperatures. Most camera systems will have a color balance calibration setting that allows for the subtle adjustments that may be needed between these two color points.

Alternatively, our FilmGrade™ 5600K A19 lamps may also be of interest. These lamps are calibrated to 5600K (and 95 CRI, of course), which is a mid-point color temperature between 5000K and 6500K. The 5600K color temperature is calibrated for use in photography, film and TV studios, but can be an equally effective and accurate light source for the purposes of digitizing artwork.

​The A19 / E26 form factor ensures that these lamps will fit in virtually all standard bulb fixtures, so this will give you lots of flexibility and room to try out different positions and orientations to get the optimal set up!

Difference between CENTRIC HOME™ A19 3000K and FilmGrade™ A19 3000K?

Several of our products are listed on multiple product pages for marketing purposes.

Specifically, our CENTRIC HOME™ A19 3000K and FilmGrade™ A19 3000K products are the same product (PN 4005.30) listed on product pages for home / residential applications, and film / photo applications, respectively.

Both products feature the same 95 CRI color accuracy and 3000K color point and are excellent options for both applications.

Do your A19 bulbs emit ultraviolet light?

I'm wondering if any of our A19 bulbs emit any light in the UV range? I'm photosensitive and just want to be really sure they're safe for me. I have been told that wavelengths less than 400 nm are considered harmful.

As can be noted in the product spectrum test report, the spectral distribution trails off before the 400 nm wavelength, so we can be assured that the bulbs do not emit any UV radiation. Below is an annotation of the spectral distribution chart which shows the light output tailing off < 400 nm.

Best bulb for viewing prints and color accuracy?

I am looking for a daylight-calibrated LED bulb that fits into a regular table lamp to view prints. Color accuracy and D50 white balance is crucial. What do you recommend?

Our D50 calibrated, 95 CRI LED lamps sound like a great fit for your needs!

For a basic table lamp with a medium-size (E26) screw base, our D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) product would be the best fit. This bulb is calibrated to the D50 standard, which would be perfect for print viewing and color accuracy.

10W A19 Lamps Now California Energy Commission Title 20 Compliant

June 7, 2021 - Waveform Lighting is excited to announce availability of our A19 10W LED lamp lineup for California customers. The bulbs listed below are now compliant to the California Energy Commissions Title 20 regulations and can now be shipped to our customers located in the state of California.

The color temperature specifications, along with their updated part numbers are also listed under each product family.

Why are you updating part numbers?

We needed to make some changes to the power electronics inside the bulb to meet the California Energy Commission's requirement for appliances to have a power factor higher than 0.7. The part number designation, printed on the packaging and lamp body, allows us to distinguish our prior lamps with a lower power factor, and those with the updated electronics for a higher power factor. See here for an in-depth explanation.

Is there a difference in the lamps' performance?

From the user's perspective, no difference in the light output, efficiency, brightness, color or flicker will be present. The California Energy Commission's power factor requirement was put in place only to improve the efficiency and reliability of power generation equipment at the power plant, and does not affect the performance of the light bulb itself.

I am not based in California. Does this update affect me?

If you are not based in California, these updates do not affect you. We plan to continue shipping non-CA compliant bulbs from our remaining inventory to our non-CA customers. Both types of bulbs will exhibit the same performance (see prior FAQ) in terms of light output, efficiency, brightness, color and flicker. If there is any confusion regarding part numbers, please see the list above for the mapping of (old -> new) part numbers.

[Archived] What is the difference between CENTRIC DAYLIGHT™ 5000K/6500K and D50/NorthLux™?

[ARCHIVED ARTICLE] This article has been archived as of November 2021 due to recent changes in our product specifications. Please see this article for the most up-to-date information on our current offerings. Customers who purchased our lamps prior to 2021 (lamps marked with PN 4005.XX rather than PN 4005C.XX) can continue to reference the archived information below.

Several of our products are listed on multiple product pages for marketing purposes. One major exception is our 10 watt A19 bulb product line, for which we offer the two part number variants for each of the 5000K and 6500K color points:

5000K:

6500K:

You will notice that the D50 and NorthLux™ product lines have a "D" prefix in the color temperature designation inside the part number. This signifies that these products are calibrated to the D50 and D65 color standards for color viewing and other vision-critical applications at 5000K and 6500K, respectively.

The CENTRIC DAYLIGHT™ products are also available in 5000K and 6500K, but they are not designed for color viewing applications. Specifically, they have a slightly greener tint (elevated Duv values), which is a closer approximation of the ANSI chromaticity targets for daylight color points.

In short, if you're looking for a lighting solution for a professional or color-critical application, we recommend the D50 / D65 designated NorthLux™ lamps. On the other hand, if you're using the lamps for indoor lighting such as light therapy, the CENTRIC DAYLIGHT™ lamps will be a great option.
