How Can We Help?

Would the diffuser in your aluminum channel affect the full-spectrum distribution of lights?

Would the light diffuser in your aluminum channel fixture for LED strips defeat or inhibit the purpose of buying full-spectrum lighting in an attempt to get more red spectrum inside living areas? I understand much of the sun's red and NIR is blocked by windows and this is why I'm trying to get more of that spectrum inside my house with lighting. Would the light diffuser have the same issues? 

Based on our tests, the aluminum channel diffusers do not affect the overall spectral distribution, including red and NIR wavelengths. They may reduce light output slightly (~15%) but this is an issue of overall intensity across all wavelength ranges, and not specifically affecting red wavelengths.

Full Spectrum LED Bulb for SAD Disorder

I am an 86-year-old female living in a retirement home. I have a small unit on the first floor of a multi-unit building. I would like advice on what full spectrum light to buy. I may get a SAD disorder, want to try one of your bulbs.

Based on the details provided, we would likely recommend our flicker-free lights that offer a high CRI in the 2700K color temperature. The flicker-free aspect is helpful for reducing eye strain, and the CRI is helpful for providing accurate color representation. 

​You may have noticed in the past that cheap lightbulbs or fluorescent tubes wash subjects in a yellow hue, which is largely due to those products having a much lower CRI than our products (With a CRI of 60-80 compared to 95+). The 2700K color temperature is often recommended for residential installations. This color temperature provides a warm glow that is easier on the eyes than the cooler color temperatures used in art studios and retail spaces.

The primary products that we would recommend would be the 2700K Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential or the 2700K CENTRIC HOME™ Flicker-Free A19 10W LED Bulb. The former option provides a warm output in a filament-style format, whereas the latter offers much higher output but is not compatible with fully enclosed fixtures.

48' x 1.5" Full Spectrum for Office Lighting

I need 48' x 1.5" full spectrum lights for my office

Based on the dimensions provided, it sounds like the fixture currently in the office space utilizes T12 tube lights. If you would like to continue using the T12 fixture with a new set of T8 LED Tube Lights, it will require a ballast bypass to be compatible with our T8 LED Tube Lights. 

As a general note, it might be helpful to know that older fluorescent fixtures contain ballasts that are not compatible with the energy requirements of LED technology. And while our T8 LED Tube Lights are compatible with some T8 fixture ballasts, any connection to operating T12 ballasts will cause hardware damage and void the product warranty. 

If you would like to rewire your fixtures to bypass the ballast in favor of a direct wire connection, we would recommend our 4000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights. This color temperature is most commonly recommended for office installations such as yours. 

Do you have a full spectrum that mimics sunlight?

I am looking for a light that mimics sunlight including UV. Do you have those, with UVA and UVB?

While we offer the 99 CRI ABSOLUTE SERIES™ LED Flexible Strip, we don't currently have any products available which can provide both UV-A and UV-B alongside the visible spectrum. We do sincerely apologize for any impact this may have on your purchase planning. 

Do you know whether (and how) dimming will affect the spectrum of Absolute Series LED series?

I'm interested in the Absolute LED series because I want a grow light that best mimics natural sunlight for use in my research lab. I am hoping to use a dimmer with them so I can have fine control over PPFD, but I'm worried that dimming will change the light spectrum. Do you know whether (and how) dimming will affect the spectrum? 

In installations where the ABSOLUTE SERIES™ LED Flexible Strip or other LED lighting products are being dimmed using a PWM dimmer, such as the FilmGrade™ Flicker-Free LED Dimmer, we would not expect for there to be any change in the light spectrum. 

For the rare installations where the dimming is accomplished through input voltage adjustment or reduction, there may be a mild change in the spectrum. 

Do you have a full-spectrum Halogen bulb (MR16) replacement bulb?

We are trying to replace a Halogen bulb (MR16) with a full-spectrum equivalent. This is being used in a broadband light therapy device. The ideal would be to duplicate the spectral energy in sunlight. Do you have the development capabilities to do this?

While not available in the MR16 standard, the closest match in our catalog would be the ABSOLUTE SERIES™ LED Flexible Strips and LED Modules. These products provide 99 CRI full-spectrum output, which is virtually indistinguishable from daylight.

That being said, the output diminishes around the 780nm point, which may mean that they are not the ideal products for the 420nm-1000nm installation requirements. 

Can full spectrum bulbs be used in standard lamps?

Can these bulbs be used in standard lamps? Are special fixtures necessary?

Generally speaking, special fixtures are not necessary for use with our Full Spectrum lightbulb products. 

That being said, we can confirm that our Full Spectrum A19 and BR30 bulbs will require non-enclosed fixtures so that a moderate amount of airflow can assist with heat dissipation. So long as the fixture is partially exposed, the lightbulbs should be able to operate properly. 

Full Spectrum Dimmable LED Bulbs for Desk Installation

I need a desk lamp that has these properties: 1. Very bright, but dimmable, continuously (no steps) 2. Wide spectrum, though not necessarily sun-like. (no unnatural peaks or dips) 3. Energy efficiency would be nice. Is this a satisfiable equation? Is there such a thing? Do you make it? 

For your desk installation, we would likely recommend our dimmable 4000K Full Spectrum E26 BR30 LED Bulbs. These bulbs have a 12W power consumption and offer a high CRI of 95+. ​

If these lightbulbs wind up not being the right fit for your installation, please feel free to take advantage of our 30-day return policy. Simply let us know which items are unneeded, and we will gladly provide a prepaid return label. 

Full Spectrum LED Bulbs for Indoor Lights

We are looking for full spectrum indoor lights for our lamps. We want something as bright as possible. Which would be best for us? CENTRIC DAYLIGHT 100W equiv or Full Spectrum E26 BR30 LED Bulb?

Based on the details provided, we would recommend the 100W-equivalent CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A21 15W LED Bulbs, as they can provide greater lumen output than our ​Full Spectrum E26 BR30 LED Bulbs (1600 lumens vs 800 lumens).

I see Waveform CRI 99, but I don’t see what products of yours offer that. Where are those products? Also, do you sell any lamps (not a standard bulbs) with full spectrum light and a lot of lumens?

We currently have two products within our line of ABSOLUTE SERIES™ 99 CRI products, which are the ABSOLUTE SERIES™ LED Linear Module and the ABSOLUTE SERIES™ LED Flexible Strip. 

We also have several light fixtures available which can output full-spectrum light, such as our LED Shop Light Fixtures, which each have an output of 4200 lumens, and our 95 CRI T5 LED Linear Light Fixtures, which can output 900 and 1800 lumens depending on the length selected (2ft and 4ft). 

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+. 

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. 

Lighting Recommendation for Painting Studio

I’m interested in purchasing strip or bulb LED tube lights and fixtures from you— something that can light a 400 sq foot space w only a glass garage door as the source of daylight. I hope to find something in the 4500k range, with a high CRI. 

As a primary recommendation, you may be interested in our FilmGrade™ HYBRID LED Strip Lights, which can be calibrated to achieve any color temperature between 3200K and 6500K. 

For an easier installation that would require less wiring, you might be interested in our 4000K or 5000K options, such as the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights, which are designed to be compatible with our LED-Ready T8 Fixtures. 

You might also be interested in our CENTRIC DAYLIGHT™ 95 CRI LED Shop Light Fixture, which is designed for easy installation using the included hook and chain. This integrated fixture has been very popular with artists who utilize garages or other areas as studio spaces, due to the easy installation. 

Are any or all of these lights dimmable?

The products that we shared are unfortunately not dimmable. If dimmable products are preferable, we might alternatively recommend the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio, or an installation that utilizes our LED Strip Lights. 

The LED Strip Lights can be mounted to ceiling or other surfaces by using the Aluminum Channel for LED Flex Strip, and powered using either in-wall power supplies or standard DC power. These products can also be controlled using the majority of standard in-wall dimmers, such as Lutron and others. 

If it proves to be helpful, we have attached a few LayoutMap links below which illustrate LED Strip Light installation options. Each diagram contains installation descriptions, as well as links to each of the recommended connecters and power supplies. 

LayoutMaps™ - LED Strip Light Layout 3001-1A

LayoutMaps™ - LED Strip Light Layout 3001-1B

LayoutMaps™ - LED Strip Light Layout 3002_2B

I’d like to know if you have a tube light structure that’s LED and also dimmable. Do the strips work in the first hanging fixture you sent?

Unfortunately, we do not have any fixtures which are flicker-free and dimmable at this time. We do sincerely apologize for any impact this may have on your purchasing plans. 

As a further note, the LED Shop Light fixtures shared in my initial reply are designed with pre-attached LED lighting products within. As such, no additional lighting products are required for operation. 

Are the LED shop light fixtures flicker free? Space is a total of 400 sq ft. Could the fixture be hung upside down so that it bounces off the ceiling as opposed to being hung as overhead lights?

We can confirm that the LED Shop Light Fixtures are indeed flicker-free.

While these fixtures could be installed in such a fashion that they shine directly upwards for indirect lighting, they are designed to be hung from the included hook and chain. 

Based on the dimensions provided, it appears that the space would be evenly illuminated for artwork creation with 31,451 lumens. This target could be reached with seven of the LED Shop Light fixtures, which each output 4,200 lumens. 

As an alternative, the target could also be reached using 18 units of the T8 LED Tube Light products, which are designed to be compatible with our LED Ready T8 Fixtures. 

Do you have overhead mountable fixtures/bulbs for art studio lighting?

I’m looking for overhead mountable fixtures/bulbs to light my 600-square-foot studio space. I’m looking for full spectrum, daylight, bulbs. What do you recommend? 

As a primary recommendation for art studio lighting, we would recommend our LED-Ready T8 Tube Light Fixtures and NorthLux™ 95 CRI T8 LED Tube for Art & Studio. These products are available in the most common color temperatures for artwork spaces (5000K & 6500K) and offer full spectrum output. 

If you would prefer to utilize fixtures that would not require hardwiring, we might alternatively recommend the NorthLux™ 95 CRI LED Shop Light Fixture, which can be easily installed from ceilings using the included chain and hook. 

For lighting installations where a mobile light source would be beneficial, you may also be interested in our NorthLux™ 95 CRI T5 LED Linear Light Fixture, which can be attached to different mounting surfaces using the included clips and magnets while offering the same high-quality light output as the above products. 

Is it possible to simulate the full spectrum natural light using two LED strip lights?

Is it possible to simulate the full range of natural light (from the red-shifted dawn/dusk to the 6500K high noon) using two of your light strips? I really like the 99 CRI flicker-free strip but it isn't adjustable (in the color space) and the 5-color simulator shows me that while I can come pretty close to your circadian specialty bulbs, I pretty much won't be using 3 of them at that setting and the flicker will be decently high. 

Do you have a WW and red-only reel? Between that and the 6500, I think you could simulate pretty much everything. Also, ideally, it would be able to modulate on an inch-by-inch basis but I know that's asking a bit much. I just have this dream of making them follow the actual pattern of the sun through the seasons inside but I'll settle first for basic functionality. 

Based on the details provided of the sun pattern installation, we would likely recommend our FilmGrade™ FiveSpect 5-in-1 LED Strip Lights, which contains RGB as well as the tungsten and daylight color temperatures, as well as our FilmGrade™ DMX LED Dimmer & Decoder with 5 Channel Output. 

Though more complex to configure than some of our plug-and-play products (such as the T5 Linear Light Fixtures), the FiveSpect and DMX Dimmer and Decoder are able to be paired with PCs or other systems for the granular control of each channel. We do not have any direct experience in programming sun simulations, though DIY sites such as Instructables may have some valuable options for your installation planning. 

Full Spectrum Lightbulbs with 488 nm Emission

I am looking for a light bulb for a rather niche application and I would like to speak with someone knowledgeable about your products so I could purchase the best one. 

I am ideally looking for the brightest full-spectrum bulb available at a reasonable cost. Ideally, the bulb should also have a reasonable emission of around 488nm and from looking at the spectrum information available it seems like most (all?) lightbulbs have peaks on either side of this wavelength. 

Would it be better to have a bulb with a lower relative intensity around a specific wavelength, but high brightness or higher relative intensity and lower overall brightness? 

As a starting point, it might be helpful to know that LED lighting technology typically features peaks at the 455nm and 520nm points. As such, most products will feature a slight valley between those two points even if they are able to provide plenty of high-quality full spectrum output. 

Further, lumens are defined as a unit of ‘luminous flux’, that being the total amount of light emitted in all directions. Full-spectrum on the other hand refers to the completeness of a light source’s spectral energy, particularly when compared to daylight. As such, these two measurements are not necessarily linked. 

Some installations, such as those using ultraviolet output, benefit from having a precise output centered at 365nm or 395nm while omitting other spectral output. In comparison, the human-centric lightbulbs in our catalog are designed to provide the full spectrum of light output for homes and other installation areas without many peaks. 

As a primary product recommendation, I would likely recommend our CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A21 15W LED Bulb, which is able to provide twice as many lumens as our A19 bulb (1600 lumens vs 800) and offers full-spectrum light with a high CRI of 95+. 

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. 

Full Spectrum LED Lights for Home Office

I know about how lighting affects our circadian rhythm and how important the right light at the right time is important for our physical and Mental Health. 

Do you sell suitable ones for the UK? I would like to start with 3 light sources in the office. Then if that works well, move on to the rest of the house.

The ceiling light in the office is an LED light, so I will need to replace that with a suitable fitting, can you suggest anything? I also have a Lamp with 2 lights on it, so I can shine it in different directions.

Would you be able to suggest the best fittings to use and the Bulbs? I want the 6500k bulbs or higher if they do that.

While there are voltage standard differences between the United States and the United Kingdom, we are happy to confirm that many of our products are designed for global compatibility. 

Further, these products are available with an E27 version, as is the name for the lightbulb base that is most common in Europe. In North America, the standard E26 base has slightly different measurements and is not compatible with E27 fixtures. 

For example, we would likely recommend our 3000K E27 CENTRIC HOME™ Flicker-Free A19 10W LED Bulb as a replacement for the lightbulb within the photo provided that reads ‘A65-2D 15’ at the top of the label, as 3000K is the most commonly recommended option for offices. As you will note, this label also lists the base size of ‘E27’, as was referenced above. 

For a 6500K alternative option, you may be interested in the 6500K E27 CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb, which is also compatible with UK voltage standards. This 6500K color temperature is most common for art production and photography. 

It appears that the desk light uses both an A19 bulb, as well as a smaller E14 bulb. We, unfortunately, do not have lightbulbs available in the E14 size, though we hope to offer them sometime in the future. 

Based on our review of the ceiling fixture, it appears to be fully enclosed. As our lightbulbs require a moderate amount of airflow for heat dissipation, they would unfortunately not be compatible with this fixture. We do sincerely apologize for any inconvenience this incompatibility may cause. 

As the above products are designed for line voltage, they are not compatible with battery operation. Regarding solar power, we would recommend reaching out to a local solar expert for advice regarding your available options. 

Full Spectrum 2x4 Office Lighting for Drop Ceiling

I need to speak to someone about full spectrum lighting for an office to fit in a 2x4 ceiling grid.

While we do not currently have any direct 2X4 recessed office light product matches in our catalog, you might alternatively be interested in our LED Ready T8 Fixtures and CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights for your installation. Our T8 LED Tube Lights offer a high CRI of 95+ and are available in the 4000K color temperature options most commonly recommended for office lighting. 

T8 LED Tube for Avian Lighting

I am trying to install full spectrum lighting for my Aviaries. I want to have LED tube lighting if possible.

While not specifically marketed for aviary installations, we would likely recommend our 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights, as they utilize the same technology and color temperature as our Avian Full Spectrum Lighting.

These products are also designed to be compatible with our newly launched LED-Ready T8 Fixtures, as well as fixtures using either compatible or incompatible ballasts.

Will the prismatic wrap on the fixture allow the full spectrum to come through? Or should I go with the one with the reflector?

While we can confirm that there is a slight reduction in light transmission through the prismatic lens (~10%), there would not be any change to the spectrum of light that passes through the prismatic lens. 

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.

Does your 6500K NorthLux T5 LED Linear Light Fixture be used for Avian Lighting?

Is this full spectrum and usable for bird ages or aviary?

​Our ​NorthLux™ 95 CRI T5 LED Linear Light Fixture does emit full spectrum light (no ultraviolet radiation, however) and can be used for avian applications. With the magnetic mounts and simple installation, this should be a great fit for your needs!

How is your full-spectrum light bulb compared to another?

I have a client who purchased some white Poplar 9w LED full spectrum light bulbs 800 lumens for their clinic. The spaces are not well-lit due to the improper amount of lights per room. Can you tell me how your product compares to these? I am considering purchasing yours to replace theirs.

While we're not familiar with the WhitePoplar brand, it does not appear that they provide photometric reports for the CRI and light output in the listings we have reviewed. 

As such, it is slightly more difficult to ascertain the difference in the quality of light output between those products and our own A19 95+ CRI bulbs. 

As one alternative, our Full Spectrum E26 BR30 LED Bulbs are often used for recessed lighting in offices, as the narrower beam angle allows for a focused light output alongside a CRI of 95+.

Full spectrum and flicker-free LED Bulbs

Which are the best flicker-free full spectrums that are easy on the eyes?

For flicker-free light that is less strenuous on the eyes, we would recommend the CENTRIC HOME™ Flicker-Free A19 10W LED Bulbs. These lightbulbs are available in the common color temperatures for home installations and produce high CRI flicker-free light output. 

If it proves to be helpful, we have also attached a color temperature selection guide below. 

Which LED Light Color Temperature Should I Choose?

Adjustable full-spectrum LED light with pulsing and flickering adjustment

Do you have a full spectrum LED products that could be delivered with a controller to regulate the output frequency (in Hz), and if so what is the range?

Based on the details provided, we would recommend utilizing a combination of the FilmGrade™ FiveSpect 5-in-1 LED Strip Lights with the FilmGrade™ DMX LED Dimmer & Decoder with 5 Channel Output. 

​As the FiveSpect product offers RGB as well as Tungsten and Daylight color temperatures (2700K, 6500K), the Decoder can be used for granular control of the output for each available channel. The available range of control is listed within the Decoder user guide and installation manual, which we have shared below for your review. 

Specifications & User Manual

We have also provided a few related articles below that may be helpful:

FilmGrade™ FiveSpect 5-in-1 LED Strip Lights

FilmGrade™ DMX LED Dimmer & Decoder with 5-Channel Output User Manual

The FilmGrade™ DMX512 LED Dimmer can output pulsed light in the area of 500Hz to 30KHz right? Could we have any real-time adjustment or preprogrammed to choose from a panel or “PC”?

There are beneficial pulsed frequency ranges in the area of 4-100 Hz, but you do not have a solution there.

We are happy to confirm that the FilmGrade™ DMX LED Dimmer & Decoder with 5-Channel Output can be paired with a PC controller for direct control of the output. Based on our review, there appear to be a few DMX PC controllers available from third-party marketplaces such as Amazon.

Unfortunately, the DMX LED Dimmer & Decoder does not have the ability to adjust the PWM frequency beyond the boundaries of the 500Hz to 30KHz range. As such, it may not be able to meet the referenced PWM frequency of 4-100 Hz. 

Would the T5 LED linear fixture cause eye damage?

My question is whether or not these lights would cause eye damage because they are "full spectrum" (NorthLux™ 95 CRI T5 LED Linear Light Fixture 4026.2F.50). I was going to use them on my desk to uplight a wall behind my computers and monitors., so I will be looking at my monitors all day long and the light will shine up on the wall behind the monitors. I do critical color work on my computer. Were these the best choice or should I have ordered something else? 

Regarding eye safety, I can confirm that the full spectrum light output provided by the linear light fixtures does not contain any ultraviolet or infrared wavelengths that could be harmful to the eyes. 

In fact, the output will likely be more beneficial than lighting products that offer a lower CRI, which can often cause eye strain and migraines. As such, we believe that the high CRI output of the linear light fixtures could be a great match for your color-matching purposes. 

That being said, you may alternatively be interested in utilizing our Sidewinder™ LED Flex Strip for D65 Bias Lighting product, which is designed to easily add D65 bias lighting behind monitors and televisions for color-accurate work. 

Full Spectrum LED Panel for House Plants

I have a basement with ground-level windows, and I have various Full panel LED ceiling boards installed for lights. My gardener recommends I change a few of them to full spectrum (unsure you make these) to keep my more tropical plants healthy as we go through winter (I live in CT). Do you have these I can send a picture of what my current 21” w X 45” panels look like.

We are happy to confirm that we offer several horticulture-focused products in our catalog, which are designed to provide the ideal wavelengths of light output for plant growth and horticulture installation. 

Based on the details provided, we would recommend the PhotonPanel™ 100W Grow Light Panel product. With the dimensions of 11”x 22”, you may be able to place two units of the product within the same footprint as your pre-existing panels. 

Additionally, as the Grow Light Panels offer an output of 12,500 lumens, we would also recommend comparing the output to the lights which are currently being used against the Grow Light Panel to ensure that preferable light output is being provided for the space. 

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. 

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.

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:

​

Do you have a full spectrum 6-inch dimmable recessed lights?

I’m looking to get a true full spectrum 6 inch dimmable recessed lights for a kitchen. 

We can confirm that we currently sell many full-spectrum LED BR30 bulbs, such as the Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential product, which are dimmable and commonly used within recessed ceiling lights.

Alternatively, there do appear to be other options available online for 6” integrated LED fixture products. Unfortunately, the integrated style is not a form factor that we currently sell. 

Do you make full spectrum LED lighting for recess can downlights?

Do you make full spectrum LED lighting for recess can downlights trim in 4" & 6"

We do not have any direct ceiling lamp replacements, but we do offer BR30 retrofit lamps which may be of interest. These have a diameter of 3.75 inches and should work well in both 4" and 6" ceiling fixtures.

​Please see below for the product link below!

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. 

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.

Flat Spectrum Light Source for Hyperspectral Imaging

I lead the NASA OSIRIS-REX Asteroid Sample Return Mission. We are planning for laboratory analysis of the returned samples. One goal is to perform hyperspectral imaging from 350 nm - 950 nm. We need a light source for this imaging. The preference is for a "flat" spectrum, meaning equal emission at all wavelengths, or as close as possible.

We currently do not offer any products that would be able to meet the requirements for such a wide range of wavelengths.

​For the visible wavelength range, our ABSOLUTE SERIES would be the best match, with coverage between 420-650 nm. 

Please see below for the photometric report:

https://www.waveformlighting.com/photometrics/TR_7001.50.pdf

​To supplement the low and high end of the spectrum, additional wavelength LEDs would be needed, but it would be quite difficult to achieve a fully flat or complete spectrum across the 350-950 nm wavelength range.

​Below are our 365, 395, and 850 nm wavelength LED strip light options, respectively:

As an alternate approach, a key objective is to perform spectral imaging under conditions similar to those that we obtained of asteroid Bennu’s surface using the MapCam broadband photometer. MapCam has four color filters (b, v, w, and x). The MapCam bands are b′ (440 to 500 nm), v (520 to 580 nm), w (670 to 730 nm), and x (820 to 890 nm) as indicated in the figure below. Can you provide light sources focused on these bands?

As far as your lighting requirements are concerned, we can certainly look into providing narrow-band sources that focus on each of those bands as an alternative to a wideband source. The only one I do see a challenge with would be the "w" channel. Please see below for my recommendations:

​b′ (440 to 500 nm): SimpleColor 460 nm

v (520 to 580 nm):​ SimpleColor 525 nm

w (670 to 730 nm): closest match would be SimpleColor 630 nm

x (820 to 890 nm): Infrared 850 nm

Please let me know if you have any questions regarding this proposed solution.

As an alternative, have you looked into using an incandescent light source with a set of optical filters? This would be beyond the scope of our LED offerings, but based on your requirements, may be worth looking into for the original broadband approach.

Recommended High CRI LED Lights for Art Gallery Lighting

I am a member of an artist-run art gallery. We have a new gallery space and would like to know what kind of lighting you recommend which would give us full spectrum color. We will want spots and perhaps tube lighting, all dimmable if possible. An architect friend recommended we get high CRI lights, at least in the 90s.

Based on the details provided, we might recommend our dimmable Full Spectrum E26 BR30 LED Bulbs. These BR30 products can provide a great full-spectrum high-CRI solution for track lighting systems.​

Regarding our tube light options, you might be interested in our NorthLux™ 95 CRI T8 LED Tube for Art & Studio product. Though these T8 LED tube lights are unfortunately not dimmable, they do offer a CRI of 95+ while being compatible with many fluorescent T8 fixtures.

Full Spectrum Clip-on Magnifying Light for Painting Studio

I need to buy a flexible clip-on magnifying light with full spectrum light for my painting studio. I was investigating some products that claim to have different levels of lighting. I read a lot on this site as I was not convinced that they provided the full spectrum needed for painting art. I like what I saw on your site but where do I get the fixtures that will accommodate your bulbs?

Based on our review of the best-selling magnifying LED lights for painting on Amazon, it appears that the majority of the results utilize embedded SMD LED panels that surround the product viewing lens. As such, it does not appear that our products could be installed within the majority of these items.

However, we are happy to offer several alternate lighting products which our customers have utilized within their studio spaces, including the NorthLux™ 95 CRI T5 LED Linear Light Fixtures, and the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio product. That being said, neither of these products is directly comparable to the magnifying LED light mentioned.

Full Spectrum LED Lighting for Big Aviary and Horticulture

I would like to confirm that your CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light can be used for lighting in my indoor aviary (dimensions: 80" H, 86" L, and 62" D). I cannot use the Full Spectrum BR30 LED Bulbs 4000K / 5000K / 6500K as I would need several of them and my ceiling is glass (the aviary is inside the sunroom). If my assumption is correct, can the tubes be plugged in or are they only hard-wired? I can only plug them in based on my setup. If there is no plug-in version of the tubes, are there alternative LED strips I can use that are full-spectrum? Finally, are the horticulture tubes hardwired or can they be plugged?

We can confirm that the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights are compatible with 4 ft fluorescent tube light fixtures which utilize the G13 base.

However, it might be helpful to know that these lights are not compatible with all ballasts present within fluorescent fixtures. Generally speaking, product incompatibility with ballast models may cause flickering, or a lack of functionality. For a full list of ballasts that have been tested as compatible, please review this link: https://www.waveformlighting.com/files/CD4020.txt

For further instructions regarding the installation methods available for these lights, we have provided a link to the product specification sheet below.

Product specification sheet: https://www.waveformlighting.com/datasheets/CS_4020-4000.pdf

If you would like to let us know which light fixture models you intend to use for the indoor aviary, we would also be more than happy to check to see if they are compatible with these lights.

Full Spectrum LED Lighting for Grocery Store Installation

I'm an architect looking for lighting that mimics daylight as closely as possible for a grocery store installation. 

We have attached two product links below that we believe might be a great fit for your grocery store installation.

As mentioned, please feel free to take advantage of our 30-day return policy for your order. If the products wind up not working well in the space, simply let us know and we would be happy to promptly issue a prepaid return label.

Full Spectrum LED Lights for Imaging Applications

I am currently looking into purchasing a full-spectrum light source to use in imaging and was wondering if you had any recommendations. Also, would it be possible to adjust the intensity? 

One of the most popular product options we've seen has been our T5 linear lamps, which can be installed quite easily in a variety of locations. These lamps feature 95 CRI which provides full spectrum and excellent color accuracy, features which are essential for accurate imaging applications.

Our D50 product in particular meets the ISO 3664 standards for color accuracy and should be a great option for your needs. Please see below for the product link:

The only downside is that these T5 lamps cannot be dimmed, so you will need to be able to work with a fixed brightness level.

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.

Full Spectrum LED Lights for Home Gym and Film Studio

I am converting a barn into a home gym that will also be used as a film studio to create content. I've been told that full-spectrum LED lights would be ideal. Hoping you can guide me to determine if your products are right, and which ones to choose. 

Based on the details that were provided for your gym and studio space, there are a few products that we might recommend. We would be more than happy to provide further details and advice about each product mentioned upon request, as well.

For example, we sell the NorthLux™ 95 CRI LED Shop Light Fixture, which is a great option for installations where non-permanent lighting options are preferred, as it can be easily re-arranged and mounted using the included hanging chains and hooks. This integrated product requires no accessories and can be daisy-chained with other units, but it is unfortunately not compatible with dimmers.

If you would prefer to utilize new T8 tube light fixtures in your space to have the benefit of easily swappable lighting, we might recommend the NorthLux™ 95 CRI T8 LED Tube for Art & Studio products.

Further, we also offer our LED strip light products. As an overview, these products are sold in reels and are compatible with in-wall power connections and wall dimmers. These strip lights can be configured in multiple ways and can be mounted using products such as our aluminum channels. These lights are also compatible with third-party lighting systems such as Lutron Caseta.

For more information regarding our LED strip lights, we have attached an article from our website below.

LED Strip Lights: Everything you need to know before you buy: https://www.waveformlighting.com/led-strip-lights

By using our lumen estimation calculator tool, we estimate that the space described would be fully illuminated by 18,821 lumens. As each product emits a different amount of light, we might recommend either 5 LED shop light fixtures (at 4200 lumens emitted per fixture), 11 T8 LED tube lights (at 1800 lumens emitted per light), or 42 feet of LED strip lights (which emit 450 lumens per foot) for your space as options.

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).

T8 Full Spectrum LED Lights for Automotive Paint Booth

I own an auto body shop and I just bought a new paint booth and was researching lights. It has 10 light fixtures which take 4 bulbs each. It requires T8 bulbs(4ft). From my research, I think I should buy full spectrum 5000K bulbs. What product do you think fits my needs? 

Based on the details provided, we believe that the 5000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light product could be a great option for your paint booth.

The 5000K color temperature option is what we generally recommend for industrial installations and color evaluation purposes, which can be noted in the article below:

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

However, please note that we are happy to offer a 30-day return policy. If the 5000K option winds up not working for your space, simply let us know and we will issue a prepaid return label.

Do you offer full-spectrum LED lights that contain UV-A?

I was wondering whether you sell any full spectrum lights that also contain UVA.

Unfortunately, we do not currently sell UV-A products that also offer full spectrum output at this time. We apologize!

Full Spectrum BR30 Bulbs for SAD and Home Lighting

I am looking to replace our whole home can lights with full spectrum bulbs to combat SAD and boost the health of my family. We live in Oregon and have limited sunlight exposure. I am trying to decide between your Ultra High 95 CRI E26 BR30 LED Bulb in 3,000K and your Full Spectrum E26 BR30 LED Bulb in 4,000K. Are they both suitable for whole-home use? Are they both full spectrum and beneficial for light therapy/heliotherapy? 

Since both items come from the same product family, which can be noted by the shared part numbers, the full spectrum features and performance will be identical across the two items. As such, both products would be suitable for home use. The only differentiator between the two can be found in the color temperature options available.

Generally speaking, the intended purposes of different spaces or rooms can help to define the proper color temperature selection. For example, general-purpose areas might benefit from the warmer 3000K color point, whereas kitchens and work spaces might benefit from the slightly cooler 4000K option.

Our website features some excellent blog posts which I have linked to below, which could prove to be useful in your selection:

Everything You Need to Know About Full Spectrum Lighting: https://www.waveformlighting.com/human-centric/everything-you-need-to-know-about-full-spectrum-lighting

We are also happy to offer a 30-day return policy if the selected items don’t work well for the space. Simply let us know which items you would like to return, and we will issue a free return label. 

Could you clarify, if the effectiveness of light therapy is the same between 3,000K and 4,000K? Or is one more effective than the other? After reading this blog post, I see “light therapy” is listed for 4,000K but not for 3,000 K. 

While both color temperature options of this product feature the same high CRI and therefore would share extremely similar health benefits, the 3000K color temperature would likely be more beneficial than the 4000K.

We have two great articles on our website that go into further detail regarding the health benefits of certain color temperatures, which could be valuable in your decision-making process.

Difference Between the BR30 Bulbs

Other than color temperature, what is the difference between the Ultra High, Full Spectrum, and the NorthLux 95 CRI BR30 LED Bulb? I'm about to move into a large studio condo and am considering my lighting options. In my previous places, I've used SoLux 4700k 12V MR16 halogens and loved their light, but they are not compatible with our fixtures. 

We can confirm that the color temperature options available are the only differences between the three products referenced, as they are of the same product family. This can be noted by the shared part number on each product page.

However, each product offers the same benefits of full spectrum, high CRI lighting, as well as a low flicker rate.

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

LED Grow Lights for under-cabinet and herbs and sprout seeds

I remodeled my kitchen and want perfect under-cabinet LED low profile strips but I want to grow herbs and sprout seeds on my kitchen counter, so am looking for full spectrum as close to daylight bright lighting. Which accessories do I choose of yours to build the perfect lighting in (4) 24” lengths and one 18” length? I have a dedicated switch on the wall to control them.

Based on the details provided, we can recommend our 5000K CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail products. The 5000K light which is emitted by this product will be very similar to that of natural, bright daylight. 

To connect the individual LED strip light segments, we recommend the Solderless Connector for Single Color LED Strip products.

When this product is paired with the 12V TRIAC Dimmable Power Supply for LED Strip, it can be adjusted and controlled using a wall dimmer product.

Here is a LayoutMap which illustrates this configuration, which might prove to be useful.

LayoutMaps™ - LED Strip Light Layout 3001-1B: https://www.waveformlighting.com/layoutmaps/3001_1B?px=-2321&py=-2245.5&pw=1642&ph=1491&s=0.1

We also offer the Aluminum Channel for LED Flex Strip products which can be used for easily mounting the LED strip lights. However, the lengths currently available may be too long for the LED strip light lengths that were described. As far as we can tell, one 16.4 ft reel of the LED strip lights, as well as one unit of the dimmable power supply, should be sufficient for your installation.

Full Spectrum LED Light for Car Repair/Restoration

30 ft. X 40 ft. with 12 ft. ceiling. All white inside. Used for car repair/restoration. Need light to reach under car lift. Did I do the calculator right? 120,000 lumens? The full spectrum is nice. 

I have attached the store links below for the products which were discussed during the call. If you could provide further details about the space, we would be more than happy to provide some more specific product recommendations as well as product quantity suggestions.

The NorthLux™ 95 CRI LED Shop Light Fixture was the primary product which was discussed. Although this item is currently back-ordered until February, this integrated fixture can be easily hung using the included chains and hooks. This product can also be daisy-chained together for easy installation.

In the event that you would prefer to use mounted ceiling fixtures which utilize tube lighting, we might recommend the CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light product.

For the installation which was described, we recommend the 5000K color temperature option. The light which would be emitted by 5000K light sources would be neutral, balanced, and very similar to natural daylight.

LED Lights to Stimulate Daylight for Winter Depression

I am looking for a lamp that simulates daylight as accurately as possible to combat my winter depression. 

I'm not sure exactly which light fixtures are being used in my house. They appear to be standard spot lights. I sincerely doubt there is anything special about them. I am looking for a colour temperature of about 5000K - 6500K.

I'm interested in your full-spectrum products. Whatever reproduces the spectrum of sunlight must be the best. Let's take the LED strip as the starting point and figure out a solution around that. I would also like it to be dimmable if possible.

The closest measurement I can get is 13 metres for my small room and 30 for my large room.

Based on your needs, it seems as though the ABSOLUTE SERIES LEDs at 6500K would be the best fit for you. From a spectral and chromaticity standpoint, this is the product that most closely resembles natural daylight at noontime, and should be an excellent choice.

​To address some of your questions about the technical aspects of the product:

Regarding the power supply, we can confirm that the ABSOLUTE SERIES™ LED Flexible Strip product would require a DC power supply for every 16.4 ft (5 meter) of length, such as our 12V FilmGrade™ DC Power Supply for LED Strip. Our DC power supply is compatible with global input voltages (100 - 240V AC, 50-60Hz), though you may require an additional wall socket adapter. 

​Further, the ABSOLUTE SERIES™ LED Flexible Strip product can be paired with the FilmGrade™ Flicker-Free LED Dimmer product for additional dimming capability. 

Depending on your installation, we might also recommend placing the LED strip lights within an enclosure which features a diffusor, such as our Aluminum Channel for LED Flex Strip product, which is available in 'flat' and 'corner' options.

​For a detailed illustration of the configuration options available for this product, the below links may prove to be useful:

LayoutMaps™ - LED Strip Light Layout 3002_3D: https://www.waveformlighting.com/layoutmaps/3002_3D?px=-2252.5&py=-2245.5&pw=1505&ph=1491&s=0.1

LayoutMaps™ - LED Strip Light Layout 3002_3E: https://www.waveformlighting.com/layoutmaps/3002_3E?px=-2252.5&py=-2245.5&pw=1505&ph=1491&s=0.1

It is going to be pretty difficult to install a power supply for every 5 metres of strip. If I run a strip around my whole room, I'm going to have a huge number of power supplies everywhere. Is there some way to hide them?

Unfortunately, we don't have a proper recommendation to hide the power supplies. However, the cords for the DC Power Supply products are of a decent length, and could be helpful in hiding the power supply some distance from the LED strip lights.

Would full-spectrum light help night worker?

My brother is in NY for a month but he has a job 7 time zones away, which means he has to start work at 2 AM (his job ends at 10:30AM). So he goes to sleep at 6 PM. I was wondering whether a full spectrum bulb in the early hours would help his biological clock. In other words, would it create a daylight-like morning for him as he works the few hours before daylight.

Our lamps are indeed designed to mimic the natural daylight spectrum, and therefore our products would be a great fit for your application. While we aren't able to make any medical claims as far as your brother's biological clock and circadian rhythms, our lamps will indeed provide a lighting environment similar to morning sunshine (especially our 4000K color temperature).

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.

Difference between Northlux and Full Spectrum BR30 Bulbs.

Could you please tell me what differences to expect between a 5000K Northlux BR30 bulb and a 5000K Full Spectrum BR30 bulb? 

The NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio lights is the same product as the Full Spectrum E26 BR30 LED Bulbs. As such, there are no differences between the two products.

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 listed in the item description for both products.

Light Color Spectrum Behind a Prism

I'm doing research for an art installation. With your lights, if I put the behind a prism, will it diffract the entire color spectrum to see the rainbows?

Because our products are designed with a CRI higher than 95, it means that they provide full spectral coverage and emit full spectrum light which is extremely similar to the spectrum of natural daylight.

As such, if our lighting products are placed behind a prism, the light refracted by the prism should produce an effect similar to what you would see with natural daylight.

Full Spectrum Strip Lights for Bathroom Installation

I am in the middle of a master bathroom renovation. Are the 4000k Centric Daylight strips full-spectrum? If not, is there any custom strip that can be made or can you recommend any other product or manufacturer for my application?

We can confirm that the 4000K CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail product feature an ultra high 95 CRI, offering a full spectrum of light output which is extremely similar to that of natural daylight.

In case it proves to be useful for your installation planning, further information regarding CRI and full spectrum can be found at the links below.

Full Spectrum E26 BR30 LED Bulb Specs and R9 value

I would like to know the specs (including R9 value) for your Full Spectrum E26 BR30 LED Bulb.

For our 3000K and 4000K, our recently measured R9 values were 90 and 97, respectively. Please let us know if we can assist with anything else!

Recommendation for Full-Spectrum Bird Room Lighting

I breed birds, primarily finches, in a 12' x'20' room with 8-ft. ceilings. Currently, the room is lit by two 4-ft. 2-tube LED ceiling-mounted fixtures which are hard-wired on a single circuit controlled by a wall switch/timer. I want to switch to full-spectrum lighting and it looks like your channel-enclosed strip lighting is a good option. Need help in making the right selections, preferably from someone familiar with birds.

Our LED products sound like a great fit for your space, and we look forward to working with you to help improve the lighting in your space, particularly concerning avian health.

Generally, our approach to avian lighting is to recommend lighting that best matches natural daylight at a spectral level, as that is typically what birds expect and need from a lighting perspective.

​For your installation, we would have to recommend our flicker-free full-spectrum LED tube lights. Our CENTRIC DAYLIGHT LED tube lights feature 95 CRI and can be used in existing 4-ft fixtures, and maybe a great way to immediately convert the lighting in your space to flicker-free and full spectrum lighting, without any need for extensive fixture reconfiguration.

Please see our product link below:

Does your full-spectrum fluorescent fixtures 5000K can be used for avian applications?

I've been using full spectrum fluorescent fixtures with 5000K and 90+ CRI, and am considering ordering from your 98 CRI products for my parrots. Do you know if your LEDs can be used for this purpose? There doesn't seem to be much literature out there on replacing full-spectrum fluorescents in aviaries with comparably rated LEDs.

Our high CRI LED products sound like a great way to enhance your existing fluorescent lighting products for avian applications.​Our 95+ CRI rating indicates that our lamps do an excellent job of recreating natural daylight, which is something that fluorescent lamps struggle to do (the highest CRI values are generally 90 for fluorescent lamps).​The one difference, however, is that LED lamps generally do not include UV radiation. Some research indicates that birds can benefit from UV radiation, so if that is a concern, you may want to be aware of that when considering LED lamps.

Can I use an E26 BR30 bulb in a recessed ceiling fixture (no covering)?

Can these bulbs be used in a typical recessed ceiling fixture? There is no cover, so the bulbs will not be fully enclosed. I really want to change the lighting and feeling down here in the basement and I'm hoping these full-spectrum lights will help.

We can confirm that the BR30 E26 LED bulbs generally fit into recessed ceiling light fixtures, so long as the fixture is designed to accommodate the E26 base.

Please note that these lights do require airflow for proper heat dissipation. So long as these bulbs are not being covered by an enclosure, they should not experience overheating.

Difference between natural "daylight" vs natural "sunlight"

I see that you characterize the difference between 4000K/5000K and 6500K bulbs as being similar to the difference between natural daylight and natural sunlight. I'm still unclear on what the difference is between daylight and sunlight?

Daylight would be the clear, bluish light coming in through a north facing window. No direct sunshine coming in, just the light from the crisp, blue sky.

Sunlight, on the other hand, has a warmer, yellower quality to it -  imagine the soft, early morning sun rays streaming in through your windows.

Some of our customers prefer the warmer "sunshine" look of our lights (4000K/5000K) while others prefer a crisper, whiter "daylight" look (6500K). Unless you are working in an industrial or color-critical environment, this decision is completely up to you and a matter of personal preference!

I would like to upgrade the lighting in my office space. My goal is to get lighting that's closer to natural daylight, and am hopeful that I can create a healthier lighting environment for myself and my colleagues. What lights should I get?

It sounds like the first question we would like to determine is which color temperature would work best for your needs. Since you mention a desire to get closer to natural daylight, my first suggestion would be to consider 6500K.

Keep in mind, however, that 6500K isn't for everyone. It's commonly used to truly replicate blue daylight, and is popular among our customers who use the lights for graphic arts and other applications that require a true match to natural daylight at a technical level.

In reality, most office spaces will utilize a "warmer" 4000K or 5000K color option. These colors would be closer to natural sunlight, rather than daylight, and might be a better fit, depending on your personal preferences. Here is an article comparing 5000K to 6500K that you may find helpful.

We would not recommend anything below 4000K for an office space, as these color temperatures will provide a much warmer, relaxing atmosphere that is more appropriate for a residential area.

With all color temperature options, we suggest a high CRI value of 95 or higher. A high CRI rating ensures that the spectral content, and not just the appearance, of the light source also matches natural daylight or sunlight.

How to "warm up" my office with better lighting

My office currently has bright fluorescent lighting that feels dark and cold. I want to “warm up” the office with lighting  that will provide a warm and homey atmosphere. What full-spectrum lamps should I purchase?

It sounds like what you are looking for are warmer color temperature bulbs. For residential applications, we typically recommend color temperatures below 3000K. Although you are located in an office setting, since you're trying to replicate a similar, more relaxing atmosphere, we would recommend installing residential bulbs in your office.

For example, here is a 3000K bulb that might work well for your needs: https://store.waveformlighting.com/collections/a19-bulbs/products/centric-home-full-spectrum-flicker-free-a19-10w-led-bulb?variant=16031459278950

Also, make sure that the lighting has high CRI (95 CRI) to ensure that the colors in your space appear natural and accurate.

The term "full spectrum" is commonly associated with "healthier light" that can help provide supplemental light, especially during the darker winter seasons. Keep in mind, however, that full spectrum lights are designed with higher color temperatures (4000K - 6500K) that replicate natural daylight. These color temperatures generally do not produce a relaxing, calming environment. Instead, they are more commonly used to provide an energetic and vibrant atmosphere.

What color temperature best approximates natural sunshine?

For those who spend lots of time indoors, installing LED lights that mimic natural light may be a top priority.

The color temperature of natural light can be difficult to pinpoint as it can range from 4000K to 6500K or higher, depending on the time of day, weather, latitude and season.

If you're after the warmer feel of natural sunshine (as opposed to daylight), 4000K may be a great option for you. 4000K can be described as early-morning or late-afternoon sunshine that comes in through a south-facing window.

5000K and higher color temperatures are also close approximations of natural light, but they are more aligned with natural daylight, rather than natural sunlight. Think of a more neutral, white light coming in from a north-facing window on an overcast day.

Flicker-free full-spectrum lighting for autism?

We have been reading that flicker-free and full-spectrum lighting might help with autism. What would you recommend?

We currently do not have any internal data or testing to verify this, and our lamps are neither approved nor marketed for treating any medical conditions or disorders.

On the other hand, there are several published studies which have linked stroboscopic flicker to autistic behavior, along with a range of other symptoms such as seizures, fatigue, eye strain. Flicker-free lighting may be an effective approach to reduce or eliminate the amount of flicker present in an indoor space and assist in promoting a healthier lighting environment.

The link between full-spectrum lighting and autism appears to be less established. Full spectrum lighting is a relatively vague marketing term, but the general idea behind it would suggest that a full-spectrum lamp provides a light spectrum that better approximates natural daylight. As such, the use of high CRI lamps (a better way to quantify "fullness spectrum") may be an effective way to introduce lighting that more closely resembles natural daylight, especially during daytime hours.

Waveform Lighting offers both flicker-free and 95 CRI LED lamps which may be an excellent options to consider. See below for our CENTRIC DAYLIGHT products, which can be used in a variety of residential or commercial (as well as classrooms and offices) locations:
