What are the differences between the three types of linear fixtures?

What are the major differences between the three types of linear fixtures you sell besides temperature?

These are the same product listed on multiple product pages for marketing purposes. Please see below for additional information:

https://www.waveformlighting.com/knowledgebase/same-led-light-listed-on-different-product-pages-whats-the-difference

Are the linear fixtures dimmable?

Unfortunately, the linear fixtures are not dimmable.

If I daisy chain two four foot and one two foot fixtures in a line, will they fit within an 11 foot span?

The actual dimensions of the fixtures is 19.7 inches and 43.3 inches for the 2-ft and 4-ft versions, respectively, so your proposed installation would comfortably fit within an 11 foot span.

Do people generally find 4000k light to be less tiring on the eyes than 5000k light? 

5000K is the preferred color temperature if one is looking to perform visually critical work, such as industrial color matching. This matches the industry-standard for the D50 color point.

For other tasks, the 4000K can definitely be considered softer and more pleasant, especially during evening hours. Please see below for an article going over this in more detail:

LED Strip vs Tube Lights in an existing T8 fixtures for Art Studio

I am helping my father order new lights for his art studio. We want to order LED lights to replace his T8 daylight fluorescent bulbs. We have two fixtures that hold six bulbs each. One fixture has a bad ballast that needs replacing; the other ballast was recently replaced.

I am trying to decide between T8 tube LEDs or adhesive LED strip lights. Your NorthLux 95 CRI T8 LED Tube for Art & Studio will work fine, but I will need to replace the ballast, correct? Or is there an easy workaround for that?

I heard that the tube lights waste a bit of luminosity because the light is directed upwards instead of all downward into the living (studio) area. On the contrary, strip lights are more efficient because ALL the light is directed toward the living area. So they are "brighter" and more lumens are shining directly into the living space. Correct?

If this is so, what product do you recommend for the strip lights for an art studio/gallery space? High CRI and color-accurate lighting are critical. My father is a professional portrait painter and color accuracy is (obviously!) important. 

Both our T8 LED tube lights and LED strip lights sound like a great option for your father's new art studio!

​In regards to your first question, you are correct on both the ballast as well as the "wasted" light situation. Unlike traditional fluorescent lamps, however, our T8 LED tube lights do not have a full 360 degree beam angle and are actually closer to 320 degrees, so there may be less concern with respect to wasted light.

​For an LED strip light solution, you will also want to consider the additional complexity of wiring and installation, as well as the additional component cost with power supplies and other accessories. That being said, we would perhaps recommend either our ABSOLUTE SERIES LED strip lights (99 CRI) or CENTRIC DAYLIGHT LED strip lights (95 CRI); links below:

As an alternative to LED strip lights, our T5 linear lamps could also be a viable option; we have provided a link for this product below:

Regarding tubes versus the strips, is there a noticeable difference in the amount of light received? Does each tube have one strip within it, or multiple strips? Is the wattage used the same?

The LED strip lights emit 450 lumens per foot, so this equates to approximately 1800 lumens for a 4-foot section, making this approximately equal to the 1800 lumens emitted by the 4-ft T8 lamp. The LED strip lights emit light in a narrower angle of 120 degrees, however, so they may be even better at reducing "wasted" lumens as we discussed prior.

The other advantage is that LED strip lights would provide you with the ability to quickly scale up or down the amount of brightness needed by installing multiple rows. Since the LED strips are quite narrow (less than half an inch), you would be able to install multiple rows in a fixture without worrying too much about footprint issues.

Is the T8 NorthLux light more suitable for art/gallery use than the strip options? The NorthLux is the only one in which there is text or reviews citing art studio/gallery use. I had assumed the Filmgrade White would be the best for artists and color rendition.

They all offer 95 CRI and 5000K, so we would not say that one is more suitable than the other. The product pages are shown primarily for marketing purposes, so if you're interested in the LED strip approach, that would certainly be fine.

The FilmGrade LED strip lights offer a color temperature of 5600K which is specific to the TV & film lighting industry. It is a perfectly suitable color temperature for art and gallery use, though keep in mind that it would not match any of the industry standards for printing or digital arts (D50 and D65, respectively).

I noticed that the Absolute offers less lumens (375/ft compared to 450/ft for the Centric and the NorthLux). Is the difference noticeable?

Yes, the difference would be noticeable, as the light output is approximately 15-20% less. That being said, installing multiple rows of the ABSOLUTE SERIES could be an easy way to make up for any brightness loss.

Lastly- (sorry for all the questions!)- if I order the T8 bulbs for my existing fluorescent fixtures, I can bypass the existing ballasts by connecting the incoming 120v wires to the blue/red wires that feed each of the "tombstones" that hold the T8 pins? Here's a short video showing that procedure: https://youtu.be/ts4dW8kLefY.

Yes, that would be a perfect way to ensure compatibility. we've included the installation manual for the T8 lamps below, which has information on wiring configurations:

LED Bulbs and Fixtures for Art Studio

Have looked but am unsure exactly what combination to order. Want a bank of three 4-foot. Need 90 or above CRT at least 5000 lumens

Our NorthLux products sound like a great fit for your art studio. For a quick-install solution, we would perhaps recommend our 4-ft T5 linear lamps, which can be installed and mounted onto a variety of locations.

We have included the product link below:

What I had in my old art studio was a bank of 4 – four-foot fixtures direct wired two tubes per fixture, direct wired and all connected to one main light switch. What I would like is 3- four-foot fixtures with two tubes per fixture. They will be hard-wired by an electrician and all operate on one main light switch.  

We would recommend purchasing three of our T8 LED-ready fixtures (2 lamps per fixture) along with two 4-packs of our T8 LED tube lights in 5000K.

We have included product links below. Please let me know if you have any questions!

High CRI Lighting for Art Studio

I need high CRI even lighting for initially ~ 5"x6 art/painting area, (ceiling joist is 7' from the floor), and if that works out another 5X6 for the working table. Looking at your LED Shop light fixture and Linear light fixture. Questions: Does either have a diffuser? Dimmer? what is cord length? 

Based on the details provided, it seems as though our T5 Linear Light Fixtures and LED Shop Lights could be a great fit for your art and painting areas!

While these products are not dimmable, we can confirm that the LED Shop Lights contain a polycarbonate lens, and the T5 Linear Light Fixtures have a diffusion cover to evenly distribute the light output. We can further confirm that the T5 Fixtures have a 12" power cord, whereas the LED Shop Light Fixtures have a 60" power cable. Longer power cables are available from third-party storefronts as well, should your installation require them. 

If a dimmable light source is preferable, we might alternatively recommend either the 5000K CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail or the 6500K FilmGrade™ WHITE LED Strip Lights. These products can be paired with either in-wall dimmers or in-line dimmers and can utilize DC power supplies or the TRIAC Dimmable Power Supply.

Many of our customers also choose to use our aluminum channels with these products, which contain diffusion covers for even light distribution. Other customers have also installed these lights so that they can be controlled using smart home systems, such as Lutron Caseta. 

T5 LED Linear Light Fixture for Model Train Layout Lighting

I'm very interested in your 95 CRI T5 LED Linear Light Fixture for lighting a model train layout that I'm getting ready to build. Two questions: 1) is a longer daisy chain cord available? and 2) do you offer a dimmable model? 

While we do not have longer daisy chain cables available, third-party options can be found online by searching for the term ‘c8 plug to c7 receptacle cable’. In our own search of Amazon, there appear to be several options available. 

​As a further note, we unfortunately do not have a dimmable version of the T5 Linear Light Fixtures available. That being said, we would be happy to share your interest in that option with my product team for future development. Hopefully, we will be able to expand our catalog to include that option within the near future. 

LED Lights Recommendation for Trade Show Lighting

We are looking for a recommendation for lighting a trade show booth. The light needs to wash down from the top of the board to the floor. The booth height is about 8'.

Based on the details provided, we would likely recommend the CENTRIC DAYLIGHT™ 95 CRI T5 LED Linear Light Fixture. This item can be powered using a simple DC power outlet, and multiple units can also be daisy-chained to a single power source for operation. This item can also be attached to surfaces using the included brackets or magnet clips. 

​For office installations, we typically recommend the 4000K color temperature, though your installation needs may vary depending on the venue. You may find that the cooler 5000K or 6500K options are better solutions. 

T5 21-inch lights with CRI 90+ Replacement Bulbs for Growing Seeds

I am looking for replacement light bulbs for starting and growing seeds. I currently have under-cabinet lights that measure 21 inches. I was wondering if you sold a T5 bulb at 21 inches that has a CRI rating of 90 or more. Every other bulb on the market has an 80 CRI rating and I’m looking for something higher.

While we do not have any 2-ft T5 bulbs, we do have a 2-ft T5 linear fixture that may work for you. The fixture has a 95 CRI rating and can be installed in a variety of locations. The only issue is that these are not replacement bulbs, so you will most likely need to remove your existing fluorescent fixture and install these light fixtures instead. 

Below is the product link:

Would fabric color be treated as with painting using 5000K, or 6500K?

Looking at Northlux 95 CRI T5 4 ft. fixtures for my wife's quilting studio. Would fabric color be treated as with painting using 5000K, or 6500K?

I read in the reviews the power cord is short and needs to be plugged directly into a power outlet. No extension cord. Is this true? I would need some sort of extension cord arrangement unless you can give advice on other options that would work.

Also what are the physical dimensions of the Northlux 95 CRI T5 4 ft. fixture? Width, Height, and Length.

Though we do not have any direct experience in colored fabrics, we have shared an article below that compares the benefits of the 5000K and 6500K color temperatures for artwork creation and color-critical work. 

Difference Between 5000K and 6500K Bulbs

In summary, the difference comes down to personal preference for creating under a neutral color point or a cooler daylight color. As the 5000K and 6500K options will offer a high CRI of 95+, both will be able to provide accurate color representation. 

As a further note, we can confirm that the T5 Linear Light Fixtures ship with a power cord that is 12" in length. Though we do not carry longer power cords, they are available from third-party storefronts by searching for the term ‘c8 plug to c7 receptacle cable’. In our own search of Amazon, there appear to be several options available. 

As the T5 Linear Light Fixtures have recently undergone a hardware update, we, unfortunately, do not yet have the dimensions available. We would like to sincerely apologize for any impact this may have on your installation planning. 

Linear Light Fixture Daisy Chain Switching

I want to turn on one switch and have a series of linear fixtures daisy-chained together come on at once. Is this possible?

We can confirm that each fixture in a daisy chain will utilize its own power setting. As such, if the fixture closest to an active power source is turned on, the subsequent fixtures will not change state. Instead, each will maintain whatever state it was set to. 

That being said, if the daisy-chained fixtures are powered by an outlet connected to a light switch, and all units are set to 'ON', they will illuminate at the same time when the switch is toggled. 

As an alternative, you may also be interested in our LED Strip Lights, which can be installed within our aluminum channels for diffusion and can also utilize a DC power supply and dimmer for adjustment. These LED Strip Lights utilize the same light sources that are present within the linear light fixtures, as well. 

Do you have LED Strip Light Ceiling Fixtures?

We would like to purchase six 4-foot-long LED strip light fixtures for a basement area in which I do painting and my wife does a variety of crafts. You have three different types available, and the descriptions don’t really tell us how they differ. Would it be smart just to buy the newest ones (Centric), or is color matching the most accurate?

Based on the details provided, it sounds as though our T5 Linear Light Fixtures could be a great match for your artwork creation space! That being said, it might be helpful to know that these fixtures operate using DC power, are exclusively controlled by the on-device power switch, and do not connect directly to line voltage. 

Further, we can confirm that the T5 Linear Light Fixtures are identical products that are provided with unique landing pages for marketing purposes. As such, the D50 5000K T5 LED Linear Light Fixture will provide identical high-quality light output as the 5000K CENTRIC DAYLIGHT™ 95 CRI T5 LED Linear Light Fixture.

This can be noted by the shared part number (PN 4026.2F.50), and we do sincerely apologize for any confusion that these product pages may have caused. 

Replacement for Daylight fluorescent bulbs

I was wondering if you could help us with trying to specify the correct LED solution to replace the daylight fluorescent bulbs we are currently using at our live animal shows. We would love to switch to LEDs, but since we are judging the animals on the color and quality of their fur we need to be as consistent as possible between the LEDs and the old fluorescents that are the current industry standard. 

The bulbs we currently use for the shows are Philips F96T 12/DX Alto and GE F96DX which are both 8' long. Our show table is usually 16'-24' long and we are trying to get a consistent, even light across the length, hence using the 8' bulbs. 

For my own use, I'm looking at ordering a pack of your Centric Daylight T8 tube lights to try out, but I'm not sure that 4' long bulbs would be ideal for the long show lights. The strip lights seem ideal as they would give us lots of flexibility on storage and set up, but I'm not sure that they would give us the same even, more diffuse light that the linear bulbs do. Currently, the bulbs are 28" above the table. 

Though we were unable to locate any details about the GE F96DX, based on my review of the Philips F96T 12/DX Alto product it appears that each 8 ft tube light provides 4200 lumens (525 lumens per foot) with a CRI of 90. 

The primary recommendation that comes to mind as an alternative is our 6500K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights. Though these provide a lower 1800 lumens per 4 ft tube (450 lumens per foot), they also provide a greater CRI of 95+. That said, please note that these lights are not compatible with all ballasts found in T8 fixtures, and may require rewiring to bypass the ballasts. 

The second option would be our FilmGrade™ WHITE LED Strip Lights, which feature the same lumens per foot and CRI as the above product. The primary benefit of the LED Strip Lights is that one full 16.4 ft reel can be powered using a single power supply such as our FilmGrade™ DC Power Supply for LED Strip or TRIAC Dimmable Power Supply (for more permanent installations). These items can be installed within the aluminum channels, which feature a diffusion panel for uniform light distribution. 

As the above products would feature a substantially higher CRI than the currently utilized Philips and GE products, we might recommend purchasing an initial test order containing one unit of our 2 ft or 4 ft 6500K CENTRIC DAYLIGHT™ 95 CRI T5 LED Linear Light Fixtures to test on your show table to ensure that the color quality matches the industry standard. 

These T5 Linear Light Fixtures utilize the same LED technology as the above products, though they would not require any additional connectors or power supplies for operation. These fixtures can also be daisy-chained (or interlocked) together for a maximum length of 70 feet, which may make them a good third option for your show table installation. 

99 CRI LED Strip Light for Proofing Slides and Photographing Artwork

I would like to replace the fluorescent bulbs in my Justlicht light table with your CRI 99 LED. Yes, you have 4-foot bulbs that I could drop in, but they are CRI 95, and I would prefer 99, as well as being able to use the LED strips in another lightbox to photograph art objects. Doable?

I am a photographer, and color corrections are critical for my work, both for proofing slides and photographing artwork. Therefore, a flexible solution of CRI 99 LEDs would be best for me. Do you ship to Iceland?

We are happy to confirm that we are able to ship orders internationally to Iceland. These orders typically take one to two days to process before being dispatched. 

Further, we can also confirm that our D50 5000K T5 LED Linear Light Fixture for Color Matching (ISO3664:2000) (PN4026.2F.50.4P) is compatible with the input frequency of 120 – 277V AC at 50 – 60 Hz. As such, it appears that the product would be compatible with the 220V AC referenced. 

If the ABSOLUTE SERIES™ LED Flexible Strip is of interest, we can confirm that the product can be used with 12V DC Power or line voltage via the 12V TRIAC Dimmable Power Supply.

Recessed LED Light for an Art Studio

I would like to talk to someone about adding lights to my art studio. I have an electrician scheduled, but he doesn't seem to know much about this subject. I was planning on putting in recessed LED lights but am now wondering what you would recommend.

Though we do not have recessed lighting fixture options, we would be happy to provide you with some product recommendations if you would like to share some details about your studio with us. For example, it would be helpful to know the size of the space, including the ceiling height. 

For a simple installation, you may be interested in our NorthLux™ 95 CRI BR30 LED Bulbs for Artwork & Studio, which are designed to be installed within recessed canned ceiling lighting. 

If you would like to utilize ceiling fixtures using a direct-wire connection, we might recommend our newly-launched LED-Ready T8 Fixtures, which are designed to be compatible with our T8 LED Tube Lights. 

If installing LED Strip Lights in the cornices of your walls is more beneficial for even illumination, we would likely recommend our 5000K 24V CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail, or our 6500K 24V FilmGrade™ WHITE LED Strip Lights. 

I have measured my art studio (which is actually a bedroom) and it is 13’7” long, 10’3” wide, and 8’ tall. There are 9” open bookshelves on one of the 10’ wide walls and two windows that face West. There is one light in the middle of the room.

I was thinking about putting in 4 flat recessed LED lights in the four corners of the room. Probably 2–3 feet away from the walls. 

I’m assuming the Northlux 95 fits in the older style of recessed cans which in the past have been quite large. But I don’t really know. Can you tell me what size can (dimensions) I would need?

And I don’t know how the other options would work. I have forwarded your email response to my electrician, but I haven’t heard back from him.

I am an oil painter and consequently need not only good lighting but accurate lightning.

We have attached an image that lists the dimensions of our NorthLux™ 95 CRI BR30 LED Bulbs for Artwork & Studio in millimeters, which we hope is helpful for your canned lighting installation planning.

These lights should fit into any standard E26 base, though please feel free to take advantage of our 30-day return policy in the event that they wind up not being the right fit. We will gladly provide you with a prepaid return label for any unneeded items. 

Based on my use of our Lumen Estimation Calculator, it appears that a room of the dimensions provided would benefit from 11,095 lumens for thorough illumination, though each space varies depending on the needs of the illumination target. As each of our BR30 bulbs provides 800 lumens, your space may benefit from additional light sources, such as the aforementioned products or the NorthLux™ 95 CRI T5 LED Linear Light Fixtures. 

The NorthLux™ 95 CRI T5 LED Linear Light Fixtures do not require additional power supplies or accessories, and can be easily installed on many different surfaces using the included magnets and metal clips, which can be useful for installations that benefit from a moveable light source.

Do you have a higher wattage of BR30 LED Bulbs for the art studio?

I have sent emails in the past regarding light for my daughter’s art studio. She presently has ordinary bulbs in there. Before, I inquired about linear lights over bulbs, but you didn’t have any in stock. So, since she currently has two light bulbs about 6 feet apart, I’m thinking of your 5000K, 95 CRI BR30 LED bulbs to replace them. However, I’m not sure 60-watt bulbs are bright enough. Do they come in higher wattages?

While our BR30 lightbulbs are unfortunately not available with a higher wattage, we are happy to confirm that our T5 Linear Light Fixtures are currently in stock and available for purchase. 

If you would like to try the 5000K NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio bulbs or the 5000K NorthLux™ 95 CRI T5 LED Linear Light Fixture for the art studio, please feel free to take advantage of our 30-day return policy if any of the items wind up being unneeded. 

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. 

How do I mount T5 Linear Light Fixtures using the mounting brackets?

How do I mount these using the mounting brackets? Where do the brackets attach to the light?

We can confirm that the metal brackets for screws and magnets can be attached to the T5 Linear Light Fixtures by sliding them onto the molded track on the underside of the fixture. 

How to properly light and install the T5 LED Linear Fixture for the art studio?

I have one waveform lamp and would like to discuss how to properly light the space and eventually hardwire the lamps.

I would like to light an artist studio approx 300 sq ft. I work/paint against 3 walls ( the 4th wall has a poorly lit window with air shaft views) 2 walls of 10 ft each x 1 wall of 12 ft and a 9' ceiling ht

I do not want to cast shadows of myself onto the canvas, the room should diffuse light. I cannot look at the bulb that I have bought it is way too bright to be low in space. I thought I might be able to hardwire them (Is that possible?) and place them in a decorative molding high on the wall but I fear it will just light the ceiling.

My other option was your suspension lights. I have no idea how to calculate what I would need for the space I have described to be lit homogenously.

As a primary starting point, we hope that it is helpful to know that the T5 Linear Light Fixtures are designed for DC power only, and cannot be directly wired to line voltage. We do apologize for any impact this may have on your installation timeline. 

For the planning of the light source in your studio space, we have attached a link to our Lumen Estimation Calculator. This tool will recommend a lumen target based on both the dimensions of the space and the purpose of the room.

Based on our use, it appears that your studio would be evenly illuminated by 24,060 lumens. This target could be met by using 41 feet of LED Strip Lights, such as our 5000K or 6500K CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail, which are the color temperatures most often recommended for artwork creation. 

We can imagine an installation in which the three reels of LED Strip Lights are connected to the three dedicated 24V power supplies to the same in-wall dimmer for control, and installed on the decorative molding within our cornered aluminum channels. We have attached two LayoutMap links below for a similar installation, in the hopes that it proves to be useful.

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. 

LED Lights for Planted Aquarium

I’m looking to change from T5 tubes to LED and looking for recommendations if you have any product lines.

We are happy to confirm that we have several options that could be a good fit for your installation. 

That being said, please note that the majority of our LED products are not IP rated for protection against the elements, such as moisture or condensation. As such, if the ideal installation area is to be submerged or located close to water, we, unfortunately, would not have a compatible product available in our catalog. 

The primary products which we would recommend would be our LED Strip Lights installed within our aluminum channels for diffusion. These LED Strip Lights can be paired with wall dimmers and power supplies, and can also be controlled using smart home systems. 

You may also be interested in our integrated T5 Linear Light Fixtures, which contain both internal power supplies and light sources. These items can also be daisy-chained together by interlocking or using the included daisy-chain cables. 

Do you have a T5 linear fixture in 2700K?

I recently purchased several CENTRIC DAYLIGHT™ 95 CRI T5 LED Linear Light Fixtures. They are great and I want to get more. Do you have/can you make linear fixtures in 2700K? I want to buy some. If not, can you suggest an alternative? 

While we do not have the T5 Linear Light Fixtures available in the 2700K color temperature, you may alternatively be interested in our 2700K CENTRIC HOME™ Flicker-Free A19 10W LED Bulb and 2700K filament A19 bulbs. 

If installing lengths of LED Strip Lights is preferable for your installation area, we also offer the 2700K CENTRIC HOME™ LED Strip Lights for Home & Residential. These products can be mounted within our aluminum channels for easy installation, can be paired with in-wall dimmers and power supplies, and offer an identical quality of light as the T5 Linear Light Fixtures. 

Do you have T5 46" 28W lights with CRI 90+?

I need a T5 46" 28w CRI 90+; do you have anything like that?

Unfortunately, it does not appear that we have any products that directly match the details provided. We do sincerely apologize for any impact this may have on your purchase planning. 

The closest match in our catalog would be the CENTRIC DAYLIGHT™ 95 CRI T5 LED Linear Light Fixtures, which are integrated light fixtures that are available in both 2-foot and 4-foot versions. These products can be easily mounted to many surfaces using brackets or magnets, and offer a high CRI of 95+. 

Can I surface mount the LED Shop Light Fixture?

Can I surface mount these fixtures on the bottom of the floor joists exposed in my basement?

As the LED Shop Light Fixtures are designed for hook and chain mounting rather than surface mounting, they may not be the ideal product for your installation. We do sincerely apologize for any impact this may have on your purchase planning. 

For alternative options, we might recommend our recently launched LED Ready T8 Fixtures, which are designed to be compatible with our T8 LED Tube Light products. 

As a further option, you may also be interested in our NorthLux™ 95 CRI T5 LED Linear Light Fixtures. While these products utilize DC power cables for operation, they can be easily mounted to several types of surfaces using the included brackets and accessories. 

T5 LED Linear Fixture lighting for an art studio?

I am looking to light an art studio located in my basement. It is 333 sf with bright white walls, 7-foot ceilings, and cork floors. The calculator says I should have 27,000 lumens or (15) of the NorthLux 95 CRI T5 LED Linear Lights. Does this seem right? Would it be better to order (4) 4 packs and return any if I decide I don't need them? and, would you recommend that light for the studio? I chose it for the price point and the low profile.

From my review of our Lumen Estimation Calculator tool, the 27,000 lumen target referenced in your email appears to be accurate for artwork creation purposes. 

​Based on the details provided, we would likely recommend purchasing the four 4-Pack units of T5 fixtures as they have a lower cost per unit. 

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. 

Can I hardwire the T5 LED Linear Light Fixture?

Can I hardwire this fixture? I want to get 2 of them and hardwire both. I could put in boxes and outlets for each, but I have things in place that will let me hardwire two of them centered on 4'.

As a starting point, it might be helpful to know that the T5 Linear Light Fixtures are designed for DC power rather than hard wiring to line voltage. As such, altering the fixtures to utilize line voltage will void the warranty. 

In the event that you would prefer a direct-wire fixture, we would alternatively recommend our newly launched LED Ready T8 Fixtures, which are designed to be compatible with our LED Tube Lights without requiring any additional rewiring or ballast bypass steps. 

95 CRI LED Lights for Art Studio

My wife ordered and received NorthLux 95 CRI T8 tubes. She thought we would just find a fixture. We are in new construction and therefore do not have existing old fluorescent fixtures and they cannot be bought. The tubes were recommended by lots of artists. Do you have a fixture for this type of LED that gives this “artist” light? We need 2 sets of 4 ft linked together with each set linked to the other. Need to know if they can be hard-wired and if are they wired from the end; and does it matter which end? 

We are happy to confirm that the T8 LED Tube Lights in our catalog are compatible with our newly-launched LED Ready T8 Fixtures. These new fixtures can be direct-wired to line voltage and do not require any rewiring or adjustment for functionality as some older fluorescent fixtures might. 

As an alternative, you may also be interested in our NorthLux™ 95 CRI LED Shop Light Fixtures. These products are integrated fixtures that do not require T8 lights or other for functionality and can be daisy-chained to a shared DC power source. That being said, please note that these fixtures are unfortunately not designed for line voltage. 

Can the LED Ready T8 Fixtures be daisy-chained? I am considering the two options you listed.

I would be placing lights on two beams running parallel and would like 8 feet on each beam which means linking two 4-foot fixtures. Can I jump over from one beam fixture to the other beam fixture and does the jump wiring have to be on a certain end? There are no diagrams indicating how this might be done.

Finally, do the T5 fixtures have similar artist LED light as the T8 fixture and what is the difference in getting one or the other?

Unfortunately, the LED Ready T8 Fixtures cannot be daisy-chained, as they only have one set of input wires and do not have output wires or receptacles. 

We can confirm that the NorthLux™ 95 CRI T5 LED Linear Light Fixtures are available, and are designed with art and studio installations in mind. 

This item is different from our T8 LED Tube Lights in that it is an integrated fixture that operates with a DC power plug. These fixtures can also be daisy-chained using the included C7 power cable, and provide full spectrum light output with a CRI of 95+. Comparatively, the LED Ready T8 Fixtures are designed for line voltage and ceiling installation, and require the T8 LED Lights for operation. 

The T5 fixture is being integrated and the DC power plug does not seem to fit with the hard-wired electrical my contractor has installed. Do you sell the 95 CRI T5 LED tubes without the fixture? If so I can look for a different fixture that I could put your lights in.

Our T5 Linear Light Fixtures are only designed for use with DC outlet power. We apologize! 

As a further clarification, the T5 Linear Light Fixtures are not sold separately from the fixture. 

Based on the details provided, it seems that the best option might be the aforementioned LED Ready T8 Fixtures as well as the NorthLux™ 95 CRI T8 LED Tube for Art & Studio. 

As another alternative, you may also be interested in using our LED Flex Strips which can be installed within Aluminum Channels and powered using direct wire as a TRIAC Dimmable Power Supply. 

36" LED Tube Light for Birds

I’m looking for a 36" tube LED that has 5000K to 5700K with a CRI of 90+ at 12 volts if possible.

While we do not have any 36” tube lights available, you might alternatively be interested in our LED Ready T8 Fixtures, which are compatible with our 5000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Lights.

For a different option that would not require an additional fixture, we would recommend our 5000K NorthLux™ 95 CRI T5 LED Linear Light Fixtures. These products can be easily mounted to surfaces, offer a high CRI of 95+, and would only require access to a wall outlet for power. 

Do you have a downlight for the painting studio?

We have a painting we just acquired and the artist recommends a downlight of 5000K. Can you recommend a fixture with light? We were planning on plugging it into an outlet below the painting.

Based on the details provided, you might be interested in our 5000K NorthLux™ 95 CRI T5 LED Linear Light Fixture. This product is designed to be easily installed using mounting clips or screws and can utilize a DC power source without the need for additional connection accessories. 

As an alternative option, you may also be interested in our 5000K NorthLux™ 95 CRI LED Shop Light Fixture. This product offers identical output as the aforementioned T5 fixture. This item can also be easily installed from ceilings using the included hook and chain. 

LED Lights for Autobody Paint Shop

Need lights for an autobody paint shop. There are existing T8 fixtures in there that are well-placed, so probably would be best to find the most accurate drop-in tube for this application. Which product and color temperature is best for this?

Based on the details provided, we would likely recommend the 5000K or 6500K color temperatures of our NorthLux™ 95 CRI T8 LED Tube for Art & Studio, which are designed for precise color accuracy. 

These T8 LED Tube Lights are also compatible with our new line of LED Ready T8 Fixtures, which do not contain the ballasts that are often incompatible with LED power requirements. 

Longer cord for T5 LED Linear Light Fixture?

Ordering a 4026.4F.40, but need more than a 1 ft cord or option for direct wire. Can you please help?

While we do not have longer power cables available, it appears that the search term ‘C7 Power Cord’ results in many options in various lengths from online retailers such as Amazon and Home Depot. 

​As a further note, it might be helpful to know that the T5 Linear Light Fixtures are not designed for direct-wire installations, as opening the fixture for rewiring and bypassing the power supply may cause electrical hazards and will void the provide warranty. 

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.

Linear Light Fixture for Colored Pencil Drawing

I am interested in a linear light fixture underneath a shelf for colored pencil drawing. There are 3 products and I am not sure which one is best for my need. Could you suggest one? Also, may the linear light be plugged into an extension cord? 

Our T5 linear light fixtures sound like a great fit for your application. Generally, our 5000K is the most popular option for artwork and other visual applications where color accuracy is paramount.

Here's a direct link to the 5000K version which we would recommend:

The product can certainly be used with an extension cord, and this is definitely something many of our customers do since the included cord is quite short.

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 size and type of reflector and socket you'd recommend for BR30 bulbs?

I am curious about what size and type of reflector and socket you'd recommend for these BR30 lights.

Though we do not have any specific reflectors or sockets that would recommend, it might be helpful to know that our BR30 lights are compatible with all standard E26 base fixtures. 

For example, would something like this work? Is that too much voltage or not enough? 

Based on our review, it appears that the fixture provided would be useable with our BR30 lights as they are compatible with 120V AC, 50-60 Hz input. As such, we would not expect that any operational issues would occur when using our lights with this fixture. 

I would like to figure out the ideal lighting setup for a wall in my painting studio. Currently, it's recessed in, creating a drop shadow in the top part of the wall. I am trying to figure out if I should get BR30 lights to direct from both sides (using a traditional reflector with light stands) OR mount the T8 LEDs below the recessed ceiling.

Regarding your painting studio setup, supplemental lighting from either the sides or below would be a great way to mitigate the issues with the drop shadow caused by the overhang.

As mentioned, the BR30 lamps have an E26 base and are compatible with reflector lamps such as the one linked below. These lamps on a light stand could work well for your needs.

Our A19 lamps, installed in standard floor lamp fixtures might also be an effective way to increase brightness in the studio area.

Alternatively, you may also want to consider our T5 linear fixtures, which can be mounted along the sides or even on the overhang itself. These light fixtures have the added benefit of being semi-portable when used with the magnet mounts; they can also be permanently fixed into the ceiling and wall locations using the screw mounts.

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. 

Do you have a longer daisy chain cord for T5 LED Linear Fixture?

I'm a visual artist and have been looking into your NorthLux™ 95 CRI T5 LED Linear Light Fixture, in 4 ft length. According to the specification sheet, it's possible to daisy chain up to 70 ft together. I've been looking at installing 14 of the fixtures ideally daisy chained across my studio ceiling as a way of having great lighting that's also movable to a different location if I ever move studios. 

What I'm wondering is if there is a way of purchasing longer daisy chain cords. The one pictured looks to be around 12" long, since I'd be going from one rafter to the next on the ceiling I'd hope to be able to purchase some from you at the same time as the fixture order would be 3-4ft long. If you don't sell those, is the plug proprietary or would I be able to use something else as a daisy chain link cord--if so what should I be looking for?

While we can confirm that the included daisy-chain cable is 12”, longer cords can be found elsewhere by searching for the term ‘c8 plug to c7 receptacle cable’. In our own search of Amazon and other retailers, there appear to be several options available in different sizes. 

For your installation planning, it might also be helpful to know that the T5 Linear Light Fixtures utilize an on-device power button and DC-plug power rather than in-wall wiring.

I was aware that it was an on device switch, I was imagining plugging the daisy chained lights into a surge protector and using that on/off switch to power them with. Would that be appropriate?

While we can confirm that the products are compatible with surge protectors that contain on-device power switches, we would strongly recommend ensuring that the surge protector and any peripheral extension cords are rated for the amperage requirements of the total interlocked T5 products. 

When the extension cord or surge protector are not rated for the same or greater amperage required by the connected products, serious issues such as overheating and melting can occur. 

For reference, the ratings of extension cords and surge protectors are shown on the product packaging and are determined by the wire diameter and length. 

Can I use the T5 Linear Fixture with 220V AC?

Can I use this light with 220-volt AC? NorthLux™ 95 CRI T5 LED Linear Light Fixture.

We can confirm that the NorthLux™ 95 CRI T5 LED Linear Light Fixture is compatible with 120 – 277V AC, as can be noted within the product specification sheet. As such, we would expect it to be compatible with your local voltage of 220VAC. 

5000K vs 6500K: Recommended Color Temperature for Photo Booth

We currently have a car dealership and a photo booth where we take pictures of cars. I am looking at your NorthLux™ 95 CRI LED Shop Light Fixture and wondering what the recommended color would be for a photo booth. 5000 or 6500? We are simply looking for the best lighting to take pictures of our vehicles. 

For photography installations where color-calibrated lighting is important, we usually recommend the 6500K option. 

If you find the 5000K NorthLux™ 95 CRI T5 LED Linear Light Fixture to be a better fit, please feel free to take advantage of our 30-day return policy, where we will gladly provide you with a prepaid return label for any unneeded items. 

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. 

T5 Linear Fixture Daisy-Chain Connectors

Do you sell the connectors for your linear T5 series in multiple lengths, or know where I could buy them? 

While we do not sell different-length connectors for the T5 Linear Light Fixtures, we can confirm that third-party options can be found elsewhere by searching for the term ‘c8 plug to c7 receptacle cable’. 

In our own search of Amazon, there appear to be several options available in different sizes from 1-15 feet in length. 

Does your color rendering LED lighting compatible with global voltage standards?

I am interested in the LED product for color rendering. However, I live in Australia with 240 AC /50hz power across Australia. Will these light work in Australia I am very interested in this product for my new studio.

We are happy to confirm that many of our products, such as the D50 5000K A19 LED Bulb for Color Matching and D50 5000K T5 LED Linear Light Fixture for Color Matching are compatible with global voltage standards, though the latter T5 option may require a socket adapter. 

Longer Daisy Chain Cords of T5 LED Linear Fixture

I would like to buy more of these and a daisy chain of 6 to 8 of these together. The daisy chain cords that came with the fixtures are too short for my needs. Do you have longer ones? I need about a 36-inch daisy chain connector. Do you have the pieces where I can assemble my own? 

While we do not have longer daisy chain cords available, we can confirm longer cords can be found elsewhere by searching for the term C8 plug to C7 receptacle cable. In our own search of Amazon, there appear to be several options available in various lengths. 

LED Strip Lights for Above-Cabinet Lighting

My daughter’s teacher has asked me to install LEDs above a cabinet for her. I’d like to use non-flickering LEDs and your company comes recommended. But I’m not technical and don’t understand if your strip lights would even work for my application (like which voltage I need). I just want something I can plug into a wall Jack and control easily. Colors would be a bonus.

Based on the details provided, we would likely recommend the 4000K CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail, as that is the most commonly recommend color temperature for classrooms and workspaces. 

While we do offer the multi-color FilmGrade™ FiveSpect 5-in-1 LED Strip Lights, it is a product that often requires PC (or automated) control, as well as the FilmGrade™ DMX LED Dimmer & Decoder with 5 Channel Output for control of the individual color channels, which may not be convenient for all purposes. 

For the above-cabinet lighting, we might recommend using a combination of the FilmGrade™ Flicker-Free LED Dimmer and FilmGrade™ DC Power Supply for LED Strip. The LED Strip Lights can also be installed within the Aluminum Channel for LED Flex Strips, which are available in flat and corner options. 

Third-party remotes may be available elsewhere as alternatives to the in-line dimmer, and would likely consist of an intermediary receiver installed between the power supply and LED Strip Lights.

In the hopes that they prove to be helpful, we have attached two LayoutMaps below which illustrate the configuration options and accessories. 

LayoutMaps™ - LED Strip Light Layout 3002_2D

LayoutMaps™ - LED Strip Light Layout 3002_2B

As an alternate option that would involve fewer components, you might also be interested in the 4000K CENTRIC DAYLIGHT™ 95 CRI T5 LED Linear Light Fixtures, which are designed to be easily mounted and daisy-chained while offering a high CRI of 95+. That said, please note that these linear fixtures are not dimmable. 

Recommended Fluorescent LED Under Light for Kitchen Cabinet

A segment of my cabinet is 70cm so what length of fluorescent LED light is ideal? 30 cm or 50 cm? I have two segments of 140 cm together, so do I put one or two LED tubes (50cm x2) for the length of 140cm? Or should I go for a 30 cm length? 

We can confirm that the total length of LED Strip Lights required for an installation is most often defined by the light output requirements. For example, a small closet may not need very bright lighting, whereas a cooktop or kitchen prep area may require much greater illumination. 

Given the details provided, you may be interested in our 3000K CENTRIC HOME™ LED Strip Lights for Home & Residential, which has an output of 1500 lumens meter and is commonly used in kitchens for under-cabinet lighting. For an installation using two parallel segments of 70 cm, the total output would be 2100 lumens (1050 per 70 cm segment). 

As an alternative, you may also be interested in our 60.96 cm (2 ft) NorthLux™ 95 CRI T5 LED Linear Light Fixtures, which are designed for easy installation and power, and have an output of 900 lumens per unit.

Longer Daisy Chain Cord T5 LED Linear Light Fixture

I was wondering if you offer daisy chain cords for the NorthLux™ 95 CRI T5 LED Linear Light Fixture that are longer than 12". If not, what type of cord might I purchase that would work with that fixture? 

While we can confirm that the included daisy-chain cable is 12”, longer cords can be found elsewhere by searching for the term ‘C8 plug to C7 Receptacle Cable’. 

We can't recommend any supplier, but there appear to be several options available on Amazon.

Please check the link here.

Lighting Recommendation for my Art Home Studio Office

I'm a textile surface pattern designer and fashion designer. I work from home at my home studio office and I am in major need of new lighting. I am in a condo currently and the ceilings are about 11ft high where my lighting will need to be placed. I would like the 5000k lighting with high CRI for color matching/Pantone and painting. The only issue is I am new to figuring out what to buy. I would ideally like to buy a long 6-8ft track lighting to place on the ceiling of my studio. I want track lighting because I still want the lighting fixture to at least look nice since it is a residential condo. 

Our high CRI bulbs at 5000K sound like a great fit for your home studio office, especially for textile color reproduction accuracy.

Unfortunately, we don't have any products that would work with track lighting fixtures. we completely understand the reason for this request for aesthetic purposes, and apologize for the inconvenience! I will definitely let our product development team know of your interest.

​Currently, the closest option for a residential installation would be our BR30 lamps, which fit into standard ceiling can fixtures. Please see below for the product link:

We also offer some T5 linear lights which can be mounted onto various surfaces. This product does not require any other fixtures in our housings and can be plugged into a wall outlet directly. Below is the product link:

The difference between D50 and NorthLux T5 Linear Light Fixture

1) What is the difference between the "D50 5000K T5 LED Linear Light Fixture for Color Matching" and the "Northlux T5 Linear Light Fixture 5000K D50" 2) Do either of the above have an add-on shade/reflector/light angle cut off device of some sort? Like the metal shades on shop lights.

We can confirm that the "D50 5000K T5 LED Linear Light Fixture for Color Matching" and the "Northlux T5 Linear Light Fixture 5000K D50" are identical products that are provided with unique landing pages for marketing purposes. As such, the performance can be expected to be identical across both items, though we do apologize for any confusion this may have caused.

As for a reflector, we do not offer any accessories that would meet your needs for the T5 linear fixture. As an alternative, we would recommend our LED-ready T8 fixtures which do offer a reflector and can be used with our T8 lamps.

I have received my fixtures and they are fantastic. Even better than I had hoped for. I would like to buy more of these and a daisy chain of 6 to 8 of these together. The daisy chain cords that came with the fixtures are too short for my needs. Do you have longer ones? I need about a 24-inch daisy chain connector. Do you have the pieces where I can assemble my own?

Unfortunately, we do not offer any longer daisy chain cables for the fixtures, but we completely understand the need as the cables are indeed quite short.

​That being said, our fixtures utilize a universally compatible "C8" connector, so any third-party connector cables should be compatible. 

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!

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:

Power Cord Length of T5 LED Linear Fixture

How long is the power cord for the NorthLux 95 CRI LED Fixture? I am setting up a new studio space in a basement room with no windows, and the outlets are low on the wall. I would like to mount the fixtures high on the wall (I think), but the power cords look too short to do that. Advice, please.

We can confirm that the included power cord has a length of 60” (152 cm). 

If a longer cord is needed to reach the outlets in the ceiling, extension cords may be used in conjunction with the included cord. 

Do you have a wall-mount T8 LED Tube Light for Bird Aviary?

I need assistance in selecting a light for my bird aviary. I want to use a led tube light that I can mount above each of my 8 individual cages. I am looking for 95+ CRI with 5000k. A bulb and fixture that fits these requirements are your NorthLux™ 95 CRI T5 LED Linear Light Fixture. Would this light work for this application? Also, can multiple cable connectors be purchased and joined together to create a chain? (I would need about 36" between each light. I would have 4 lights on the top row and 4 lights across the bottom row. 

Based on the details provided, it does appear that the 6500K NorthLux™ 95 CRI T5 LED Linear Light Fixtures would be a great fit for your bird aviary installation. 

These fixtures can be directly connected in series and can be connected using the included daisy-chain cords as well. It might also be helpful to know that these products are available in both 2 ft and 4 ft versions, as can be seen on the product page. 

While we have not tested installations using a series of connected daisy-chain cables, it might be helpful to know that longer third-party C8 cables available from other marketplaces are likely compatible as an alternative option. 

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.

What is the weight of the NorthLux™ 95 CRI T5 LED Linear Light Fixture?

I was wondering what the weight was of the four-foot Northlux T5 Fixture. (Making sure it's not too heavy for where I'll be putting it.) 

We can confirm that the 4 ft version of our NorthLux™ 95 CRI T5 LED Linear Light Fixture weighs approximately .59 lbs. 

D50 vs D65 for Color Matching Stained Glass

I am building a light box to use with color matching stained glass. Need to match sunlight. I'm considering items 4026.2F.50 or 4026.2F.65. Which would you recommend for my application?

For matching daylight, we would recommend our D65 color temperature option of the NorthLux™ 95 CRI T5 LED Linear Light Fixture. (PN4026.2F.65)

The light box where the light(s) will be installed will have a glass or plexiglass (I haven’t decided which is best to use) cover of approximately 24”L x 19”W. Would one bulb be enough or two, three?

Based on our limited experience with lightboxes, we have found that the ideal lumen output is often defined by the purpose. 

For example, a light table used for the photography of negatives might require a very high output to assist with high-quality capture, whereas you may not require as much output for your stained glass work. 

If you have a precise lumen target for your lightbox, it might be helpful to know that the 2 ft T5 Linear Light fixtures have a lumen output of 900. 

Studio Lighting 1962 Home with Unfinished Basement

Could you please calculate and advise on which fixtures to light the 21’ x 26’ x 8 high basements with exposed rafters? I would like to use this space as my art studio. There is a single very small glass block window 15” x 20”. 

By using the lumen estimation calculator, we received a similar 42,931 lumen estimate recommendation for your space based on the dimensions. 

It might also be helpful to know that the referenced NorthLux™ 95 CRI T5 LED Linear Light Fixtures are not usually installed as ceiling lighting due to their usage of DC power via wall plug for operation. 

If in-wall power and wall switches are preferred for the basement lights, you might alternatively be interested in our LED Ready T8 LED Fixtures and NorthLux™ 95 CRI T8 LED Tube for Art & Studio. By my estimation, the 42,931 lumen suggestion can be reached with 24 of the aforementioned T8 lamps. 

Automotive Paint Inspection Lighting

I would like to speak with someone about possibly improving our inspection lighting to help us better identify defects that are easily seen in sunlight but not under standard inspection lighting.

Our high CRI, daylight-calibrated light sources sound like a great fit for your needs. Specifically, our D50 lamps may be an excellent option to replace the current standard lighting, as the D50 chromaticity point and spectrum approximate noon sunlight.

If you can tell us a bit more about the form factor that would be best suited for the manufacturing / inspection site, we may be able to provide some additional insights as far as product types and configuration.

As a starting point, our T5 linear fixtures with D50 chromaticity is a very popular option among our professional customers looking for a relatively straightforward and ETL-listed turn-key lighting installation. The lamps have a 95 CRI rating, are available in 2-ft and 4-ft configurations, and can be daisy-chained.

Our shop light fixtures also feature D50 light quality and can hang above the inspection station, if that is a potential installation location / method.

For a 99 CRI, D50 option, our ABSOLUTE SERIES LED components could also be a viable candidate for your installation. Our LED strip lights, for example, could be installed along the sides or above the inspection subject. Do keep in mind that the LED strip lights do require a bit more configuration work, which could make replicating the installation across multiple locations a bit more challenging.

I have attached a picture of one of our decks that I am interested in improving the lighting (we have 6 areas throughout the plant that are similar). The side and top lights are 8 feet and the angled lights on the top are 4 feet. I also attached some pictures of our current lights. Would we be able to simple replace the led strip inside with your 99CRI strip?

We've taken a look at the existing fixture, and it appears to be a product that does not have any user-replaceable parts and is not designed to be retrofitted. As a result, this leads us to two concerns about this approach:

​1) The power supply unit uses constant current with a voltage output range of 25-45 volts. Our LED strips require constant voltage at 12 volts or 24 volts, so the power supply units that are included in your fixture would not be compatible. Replacing both the LED strips and the power supply units to re-use just the housing may not be the most optimal.

2) Modifying fixtures will likely void any safety approval marks such as UL or ETL, as these marks are granted at the complete fixture level. In our prior experiences working with customers in manufacturing environments, safety approvals have been a firm requirement.

If you would like to continue to pursue the fixture retrofit approach, we would recommend using our flicker-free power supply unit listed here in conjunction with our ABSOLUTE SERIES LED modules, listed here.

Does your NorthLux Shop Light Fixture support flush mounting and hard wiring?

Does your Northlux shop light support flush mounting and hard wiring? Is there an adapter that allows daisy chaining by directly connecting one unit to an immediately adjacent (touching) unit instead of by a cable that would effectively force some separation? 

We can confirm that the LED Shop Light fixtures are designed for hanging installations, and are not designed to support flush-mounting or hard-wiring. 

​Additionally, we do not have connecter accessories available that might allow for directly interlocked the shop lights, and we do apologize for any impact this might have on your purchase planning. 

As an alternative, you might be interested in our NorthLux™ 95 CRI T5 LED Linear Light Fixtures, which are designed for interlocking, daisy-chained power, and can be flush-mounted using the included screws or magnet brackets. 

Do you have daisy chain cables longer than 12”? (Up to 20’)? Do you have adapters to hardwire the units?

We currently do not have longer daisy chain cords available, though it might be helpful to know that standard three-prong plug extension cords are compatible with the daisy-chaining of the LED Shop Light Fixtures. 

Additionally, we unfortunately do not sell adapters or kits for hardwiring the LED Shop Light Fixtures. We apologize!

As an alternative, you might be interested in our LED Ready T8 LED Fixtures, which are designed for ceiling mounting and direct-wire connection. These fixtures are designed to be compatible with T8 LED Tube lights, which have the benefit of being easy to replace in the event of a malfunction, compared to the shop light fixtures which utilize affixed, non-replaceable lights. 

Fluorescent Replacement for Office Space Lighting

We are moving offices, and I am searching for lighting to replace our current fluorescents. We are looking for human-centered lighting that will create a better work environment for our employees. The space needs lighting that totals 108,000 lumens. However, we already have purchased some hanging pendants that account for 24,000 lumens. As a result, we are looking for additional lighting to account for another 84,000 lumens. At this time, we are thinking that hanging linear lights would be the best option. I have looked at your Northlux Light Fixtures as an option. What would you recommend? Could you point me in the right direction for products and provide me with an estimate?

Though the NorthLux™ 95 CRI T5 LED Linear Light Fixtures are easily mountable and provide high-quality light, they are not usually used for office spaces as they are not dimmable, and require DC-plugs for power. 

These limitations can be detractors for customers who intend to connect the lights to utilize in-wall power, or for customers who want to be able to adjust the output using a wall dimmer or smart dimmer system. These same considerations are true for our NorthLux™ 95 CRI LED Shop Light Fixtures, which also rely on DC plugs. 

As an alternative, you might be interested in our NorthLux™ 95 CRI T8 LED Tube for Art & Studio, as they can be installed within T8 fixtures as well as easily replaced if the individual lights encounter any malfunction. 

​For an installation where utilizing dimming and in-wall power are preferred, we would recommend the 99 CRI ABSOLUTE SERIES™ LED Flexible Strip Lights. These products can be ceiling-mounted within channels and are able to offer our highest quality of light output. 

NorthLux vs. Absolute Series for Painting Studio

Could you please help me understand the pros and cons between Northlux and Absolute for a painter/artist studio? It seems that a 99CRI would be better, but is there something I'm not understanding? 

When considering the Northlux and Absolute series of products, the two considerations are the form factor and CRI. 

Though the Absolute Series products can offer a superior CRI of 99, they are currently only available in LED strip lights and LED modules. These products would require more configuration effort to install and could utilize power supplies, dimmers, and wiring connection accessories. 

In comparison, though the Northlux line has a slightly lower CRI of 95+, the line includes lightbulbs, linear light fixtures, and shop lights. Each of these form factors can benefit different spaces and are generally easier to install. 

For example, some of our artist customers have let us know that the NorthLux™ 95 CRI T5 LED Linear Light Fixtures have been a great pairing for their studio spaces and artwork creation. By viewing the bottom of the product page, you will notice a few recent comments left by customers. 

Proper Lighting for an Art Studio

I recently renovated my art studio & I am seeking your advice on selecting some lighting. The studio is 100 sq. ft. (10' x 10') with 8' ceiling height. I have added an (L-shaped desk) with shelving above. The length of the desk is 6' x 4' & shelves are 24" above the top of the desk. Shelf brackets are made from black gas pipe & are 16" in the center.

I do have a window in the room with some natural light put is not north facing. I need your advice on (5000K or 6500K) for the linear light fixture above the desk area as I do some of my artwork on this desk as well as the drafting table. The linear fixture indicates that it has a 12" power cord that you can plug into a wall outlet. I do not have enough length to plug into the outlet, so could I use a small extension cord plugged into the 12 " power cord on the fixture then plugged into the wall outlet?

Generally speaking, in the event that you hope to match the available natural daylight, we would recommend the 6500K option. This option would likely assist in supplementing the moderate amount of light available from the studio window. 

Please feel free to take advantage of our 30-day return policy as well, in the event that you would like to try both color options in your studio. Simply reach out, and we will gladly provide a prepaid return label for the unneeded items. 

Though the pre-included power cable may not be long enough, we can confirm that third-party power cables or extension cords can also be used with the linear lights. These products can also be daisy-chained or connected together (up to ten units), if utilizing a single power source is preferable. 

Based on my results from our Lumen Estimation Calculator, it appears that the 10x10x8’ space would be illuminated with roughly 7,963 lumens, though a lower amount of lumens may also be sufficient. For reference, the 2-ft linear lights offer 900 lumens, where the 4-ft linear lights offer 1800 lumens.

If that the linear light fixtures are to be used as the primary studio light source, you might benefit from additional lights. As such, we recommend one 4-Pack of the 6500K 4-ft NorthLux™ 95 CRI T5 LED Linear Light Fixtures.

Does your NorthLux™ 95 CRI T5 LED Linear Light Fixture dimmable?

Is this fixture dimmable?

We can confirm that our T5 Linear Light Fixtures are not dimmable, and I do apologize for any impact this might have on your purchasing process. 

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. 

Do you have a D65 lighting with the exact color temperature?

Do you have a D65 lighting with the exact color temperature?

We are happy to confirm that we offer many D65 products, such as the NorthLux™ 95 CRI T5 LED Linear Light Fixture and the ABSOLUTE SERIES™ LED Flexible Strip product. 

For more information regarding the D65 photometric reports for each item, please reference the downloadable PDF files found on each product page. For additional details regarding the D65 ISO standard, we have shared an informative document from our website below which I hope proves to be helpful. 

What is D65 and what is it used for?

Will the present absolute LED series support color measurements?

For more information regarding the color output of the D65 products, we would recommend reviewing the photometric data page. 

I am also curious to know whether you have a similar daylight source in the form of a fibre optic source.

We can confirm that we currently do not sell our D65 products in the fiber optic form factor. 

Will you be able to provide us with a sample say 10 cm for our initial trials?

We are not able to provide product samples, and I do apologize for any impact this might have on your purchasing process.

Can we also control the intensity of the LED source? If so, what would be the maximum and min Lux measurements

When pairing the LED strip lights with a compatible controller such as our FilmGrade™ DMX LED Dimmer & Decoder with 5 Channel Output, the output can be controlled with granular precision. 

Could you also please share the applications in industry where they are utilizing the same?

Unfortunately, we're not at liberty to disclose the requested industry details. 

Do you have high CRI 3000-4000k linear fixtures for under-cabinet lighting?

I’m doing a kitchen reno and I’d like to buy some high CRI under cabinet lighting. I saw you have these under-cabinet LED modules, but I’m worried about glare without a diffuser. Do you have any high CRI 3000-4000k LED light bars or linear fixtures? 

Though we would usually recommend the NorthLux™ 95 CRI T5 LED Linear Light Fixtures as a primary alternative, these products are not available in 4000K. As such, they may not be a good option for your preferred under-cabinet lighting. 

As a second option, we would instead recommend the 24V 4000K CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail. This product can be paired with in-wall dimmers (including smart-home dimmer systems) and powered using in-wall power supplies. Though this is a more involved installation process than the T5 linear lights, the product is able to offer some large advantages.

​Additionally, these LED strip lights can be placed within channels such as our 3.3' (1 meter) Aluminum Channel for LED Flex Strip product, which ships with diffusor covers. In the event that the 3.3' length is not to preference, I believe that third-party channels are also available from third-party marketplaces. 

​For your reference, I have attached a few interactive LED strip light layout diagrams from our website below. 

LayoutMaps™ - LED Strip Light Layout 3001-1A

LayoutMaps™ - LED Strip Light Layout 3001-1B

Can the channels you mention be cut? I have a few smaller nooks (e.g. 18-30"). Would you recommend the flat or corner channels for under cabinets? I'd place them near the front of the cabinet.

In our experience, under-cabinet lighting typically aims directly downward onto the counter surface area. Although we could easily imagine an installation where the corner channel units are back-mounted, this installation does not seem overly beneficial for lights that are to be installed towards the front of the cabinets. 

​As such, we would likely recommend the flat version of the aluminum channels for your installation. 

I'd like to go with the LED strips, and my electrician is coming in soon so I would like to get all the components for pre drywall ordered immediately. For the power supply, do I need a junction box, and should I get 12V or 24V? I see that 24V is out of stock until June 21 and I may need it sooner than that.

Would you be able to help me get a list of all the supplies I need including wire, etc? I'm looking at about 13 linear ft of cabinets / shelving to run strips under, with two opposite walls to cover. I've attached my kitchen layout so you can see.

Based on our conversations regarding the 24V CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail, we would recommend utilizing either the 24V TRIAC Dimmable Power Supply for LED Strip or the 24V CENTRIC SERIES™ Flicker-Free Dimmable Power Supply for LED Strip. 

As the two products are identical feature-wise, the primary difference can be found in the smaller dimensions of the Centric Series power supply, which can be beneficial for installations that require a smaller footprint. If the power supply is required ahead of the TRIAC 24V availability date, we would then recommend the Centric Series. 

As the LED strip lights require 5.5 watts per foot, and as the 24V power supplies can offer 96 watts, each power supply can safely provide power for a maximum of ~17 feet. As such, we would recommend utilizing two power supplies to independently power the two 13 ft segments. 

We have attached links to our LayoutMaps diagram pages below, which contain layout instructions as well as links to each of the recommended connector accessories. I have also shared a link to the list of compatible dimmers (including smart home dimmers) that our power supplies are compatible with. 

​You might notice that Layout 3001-1C illustrates an installation that utilizes two power supplies for two product reels that are connected to one wall dimmer, which might be of interest for your kitchen installation plans.

Compatible Dimmer List for CENTRIC SERIES LED Power Supply

I have about 13 ft total of strips to run along the two walls combined, not 13 ft on each wall. That being said there will have to be wire inbetween, but does that require extra wattage just for connecting strips across the room or can I get away with one power supply?

Can/should I put these power supplies inside a cabinet, tucked under an upper cabinet, or in a toe-kick or something so they arent covered in drywall in case of replacement, etc?

What wire should I get and can my electrician substitute out some locally available wire? Which wire should I get and can my electrician?

If you are planning to utilize 13 total feet of LED strip light product,we can confirm that one power supply should be more than sufficient. 

We can also confirm that the power supplies can easily be tucked away inside of cabinets or toe-kicks for easy adjustment, and do not necessarily need to be installed within the walls except to have access to in-wall power and connection to any in-wall dimmers or light switches.

Generally speaking, we recommend utilizing 16 AWG wiring to reduce the chances of voltage drop, which is available in our storefront. That said, this gauge of wiring is also very likely to be available from your local hardware stores. 

​Your electrician will likely be able to provide precise advice for the installation, though we generally like to inform customers that large wired gaps between the power supplies and products can cause some voltage drop, though this can be reduced by using a higher gauge of wiring. 

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. 

LED Strip Light Wire Gauge & Voltage Drop Calculator

Lighting Solution for Color Matching and Custom Picture Framing Presentations

I am seeking a solution for our color matching along with our custom picture framing presentation areas. I am looking for a lighting solution for two areas of concern. Number 1 is a color-matching room as I would call it. The size is 10 ft x 10 ft which currently has a 2 ft x 4 ft fluorescent lighting that would serve as a neutral light area. I would be color-proofing original Artwork to my calibrated monitor and my printed images. The second is two sales presentation tables for picture framing designs that I would like to place a fixture over so that we have a neutral color cast over this area. The tables are approx. 4ft x 8ft sections.

By entering the dimensions of the color matching room into our Lumen Estimation Calculator, we estimate that the area would be fully illuminated for artwork and capture by ~7,963 lumens. We entered 8 ft as the ceiling height in my process, though you will likely find value in adjusting this to receive a more accurate estimate. 

For this space, we would recommend 5-6 units of the D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000) product. These T8 tube lights offer 1800 lumens per tube light, as well as a CRI of 95+. If the fluorescent fixtures being utilized contain ballasts, we would recommend checking our compatibility list to ensure compatibility. 

For the presentation tables, you may be interested in the 5000K or 6500K NorthLux™ 95 CRI LED Shop Light Fixture product, which offers 4500 lumens per unit and is easy to install utilizing the included chain and hook. 

As an alternative, you may also be interested in the ABSOLUTE SERIES™ LED Flexible Strip product, which has a CRI of 99, making them virtually indistinguishable from daylight. This item is available in both the D50 and D65 ISO standards and can be installed within ceiling-mounted channels, and paired with a wall dimmer via the in-wall TRIAC dimmable power supply. 

I have yet to progress further on this project and I am looking to expand my needs for this project. We have needed to reorganize the lighting area to a larger footprint 30’ x 26’ x 9’. I have attached a photo of the area and specifically the trusses that I hope to use to attach the lighting to. The trusses run the length of 30’ and there are 4 runs in total at 6’ apart. 

Since my main focus will be to properly evaluate a scanned piece of Artwork to what is printed the less color shift lighting brings the better. I look to your recommendation to best achieve this goal. Can you recommend a lighting package for this area?

For installations that require precise color accuracy, we usually recommend our D50 and D65 ABSOLUTE SERIES™ LED Flexible Strips. These products can offer a 99 CRI, and provide light output that is virtually indistinguishable from daylight. 

​As you will note from the review section of the above product page, several of our customers have found success in using this product for art production and photo capture. We certainly hope that this product is helpful for your installation as well! 

In the hopes that they prove to be helpful, we have attached the photometric reports for each version below:

D50 ABSOLUTE SERIES™ LED Flexible Strip 

D65 ABSOLUTE SERIES™ LED Flexible Strip 

Would you have some install photos to see how these would be installed? Would these just get attached to the trusses and left exposed or I have seen on your website there is a trim package but would the covers affect the light in any way?

Unfortunately, we do not have any installation photos readily available that we could share. We apologize!

We usually recommend installing the LED Strip Lights into channels, such as our flat Aluminum Channel for LED Flex Strips. 

​When installed within the channels, the light products can be easily adjusted or replaced if outages occur with more ease than if they were attached directly to trusses. These channels will also help to protect the LED light products from dust and residue that might cause operational issues in the future. 

The light covers will reduce the overall transmission by roughly ~10% as most polycarbonate diffusion panels will, though the color temperature and spectrum of output would not be expected to change. 

​

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.

I'm very interested in replacing the lighting in my shop/studio. I have 8' T12 fluorescent lighting that I replaced with LED, and they're hurting my eyes more than fluorescents do. I was told that 2700k and the high 90s or above CRI rating possible was best. I don't see an 8' replacement on your site, just 4ft. Is that correct? I'm feeling overwhelmed and confused with this project. Could you recommend lighting options for my shop with something as close to daylight as you have? Am I better off having rows of screw-in type bulbs everywhere or do you carry strip or tube lighting that you would recommend? 

First of all, I suspect that the eye strain you are experiencing may be the result of hidden flicker in the new LED lamps, rather than a color specification issue. Here is a video that explains how you would be able to detect this using an iPhone: https://www.youtube.com/watch?v=QTVjokUy2Dw

Since your fixtures are only able to accommodate 8 ft lamps, we, unfortunately, would not be able to utilize them with any of our lamps. Without having to replace the fixtures entirely, however, you may be able to use our NorthLux T5 linear fixtures as a retrofit solution (https://store.waveformlighting.com/products/northlux-95-cri-t5-led-linear-light-fixture).

​The T5 linear fixtures are available in 2-ft and 4-ft lengths and can be mounted inside existing fluorescent fixtures using the included magnet mounts. These could very well "replace" the 8 ft lamps without actually needing to use the same lamp sockets, and this could also allow you to repurpose your existing fixtures as housings for the new lamps.

​These are flicker-free, and have 95 CRI and 5000K / 6500K light output, ensuring excellent color accuracy that matches natural daylight.

I was actually just looking at those calculating how many it would require to at least match the lumen levels I have now. Great CRI rating, though I was looking more in the 3-400k (max) bulbs as anything higher than that is just too blue for me. I have an eye condition and no longer wear the proper contacts. 

It's a 3800 sq ft area so unfortunately it's going to require a number of lights to illuminate properly. 

Determining the total brightness needed is indeed a bit tricky, as sufficient brightness is very important for studio work, but having too much brightness could lead to potentially unpleasant glare effects as you've experienced. We offer a lumen calculator on our website here, which may be of interest: https://www.waveformlighting.com/lumen-calculator

Based on the 3800 square feet input, the calculator suggests approximately 150,000 lumens for your space if you are looking to reach a sufficient illumination level for studio work (80 footcandles). This would require approximately 85 of our 4-ft T5 lights to illuminate the entire space with sufficient brightness.

Of course, based on your personal preference, 80 footcandles may be too bright and intense. We could definitely cut this down to half, to 40 footcandles using 43 of the 4-ft T5 lamps, which is the generally recommended brightness level for a standard commercial or office space installation. 

What's the difference between the T-5 and T-8? Is that just a matter of what fixture you have? 

In addition, I also meant to ask if the daylight tube bulbs work differently than the non-daylight ones. I'm expecting to have to replace all the sockets as I have a variety of lights that would complicate things to match. I think it would be best to just replace them all and start off with matching sockets. Can I assume these plug into power directly as others do? Or do they need some sort of ballast?

The primary difference between the T8 lamps and the T5 fixtures is that the T8 lamps require a fixture to house them (typically traditional T8 fluorescent fixtures), while the T5 fixtures are an integrated LED fixture that does not require installation inside a fixture.

​Generally speaking, we would recommend the T8 lamps for customers who have an existing 4-ft T8 fluorescent fixture. You mentioned that you have 8-ft fixtures, which are unfortunately not compatible. As such, we would recommend foregoing the T8 lamps unless you had plans to reinstall new T8 fluorescent fixtures.

​The T5 fixtures, on the other hand, do not require a separate fixture and can be installed in virtually any location. A fluorescent ballast is not required, and the product can plug into any wall outlet or extension cord.

​Our daylight/non-daylight designations relate to color temperature and do not have any bearing on the installation configuration.

Sounds like T8's may fit the bill. I'm a fabricator, so if need be I can retrofit the 8ft fixtures or fabricate new ones with new sockets. Though purchasing T8 fixtures sounds best. I think we may still have some in storage actually. 

Sounds like a plan! As long as the sockets are spaced at the correct spacing to accommodate the 4-ft T8 tube lights, there shouldn't be any issues there. From a liability perspective, we do need to mention that the company's official recommendation is to only use fixtures designed specifically for 4-ft tube lights, but from an electrical standpoint there should not be any issues operating the 4-ft T8 lamps.

The "CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light" can be used with both shunted and non-shunted sockets. Please see below for the installation manual showing the various permissible wiring configurations:

https://www.waveformlighting.com/datasheets/UM_4024.pdf

What's the highest wattage available? Is 1,800 lumens the brightest 4ft T8 you carry? My 8-footers are 110w @ 8,800k per bulb, with 4 in each bank. 

The only as well as the highest wattage available is 18 watts at 1800 lumens each.

For the sake of confusion would you mind forwarding me links to the T5 and T8s you're referring to? 

Please see below:

Do the T8s need a reflector-type hood to be more efficient because the light radiates out? Or do they already focus downward? 

The light is emitted at a 320-degree angle. A reflector is not necessary but may help in producing a bit more "useful" brightness.

Diffusion difference between T8 LED Tube, Shop Light, and T5 Linear Fixture

I am a fine art photographer who is evaluating large prints that will ultimately be shown in museums and galleries and private residences. I'm having a difficult time understanding the differences between the NorthLux™ 95 CRI T8 LED Tube for Art & Studio in 5000k and the D50 5000K T8 LED Tube Lights for Color Matching. Is the light output different between these two options? I am not needing any sort of specific ISO spec, just looking for the best quality of light for the application. Also, I am curious about the differences in diffusion between the bare tube, the T5 linear light fixture, and the shop light. Is there any noticeable difference in the quality of light- ie more even diffusion from the linear or shop light? 

For starters, we can confirm that the 5000K NorthLux™ 95 CRI T8 LED Tube for Art & Studio and the D50 5000K T8 LED Tube Lights for Color Matching are identical products that are provided with unique landing pages for marketing purposes. As such, the performance can be expected to be identical across both items, though we do apologize for any confusion this may have caused.

Also, we're not sure that we can provide any applicable metrics or specifications on this, but it would seem to me that the diffusion performance of the T8 LED lamps would be best, followed by the T5 linear fixtures, and finally the shop light fixtures.

The reason for this is that the T8 lamps, by definition, have a 1-inch diameter and this allows for the light to spread out from a larger surface area compared to the T5 lamps, which have only a 5/8 inch diameter. The shop lights do not have any diffusers on them, and all light is directed downwards from the fixture. As such, if glare and "hotspots" are of concern, we would not recommend the shop lights for your installation.

​Compared to the T5 fixtures, the downside of the T8 lamps would be that you would need a separate fixture, but if you are looking for the softest, most diffuse light source, the T8 lamps would be our recommendation.

T5 LED Linear Fixture vs LED Strips for Kitchen Lighting

I need to find linear lighting for my mom's kitchen and am having difficulty trying to find a solution that will fit our requirements for brightness, weight, and ease of replacement in the future. I am in between something like an LED T5 and LED strips. This will be for area lighting near the ceiling that will replace the current T12 LEDs. 

Based on the details provided, we might recommend our CENTRIC HOME™ LED Strip Lights for Home & Residential product. This product is available in the 2700K and 3000K color temperatures, which are the most commonly recommended color temperature options for kitchens and living areas.

Though the T5 Linear Light Fixtures are indeed convenient to install, it might be helpful to know that they can only be powered by DC wall plugs and utilize individual power switches. As such, they may not be convenient for daily use in high-traffic areas such as kitchens.

The LED Strip Lights can be powered by an in-wall TRIAC dimmable power supply and can be controlled using in-wall dimmers. They can also be easily mounted along the ceiling using the Aluminum Channel for LED Flex Strip product, which is available in both flat and corner versions. The LED strip lights also have a 3-year warranty and can be fairly easily detached from the mounting channels and replaced using rubbing alcohol in case they experience any failure or malfunction.

I have attached a few layout diagrams below, as well as other instructional posts from our website for your review:

LED Strip Lights Introduction

Which LED Light Color Temperature Should I Choose?

Flicker-Free T8 LED Tube Light

I am trying to use these lights for my film studio, where I shoot high-speed video at around 1000 frames per second. Would this work for this type of application? Can I use a standard LED T8 light fixture for these bulbs and still get a "flicker-free effect?"What is meant by "Flicker-free" when connected without a fluorescent ballast?

We are happy to confirm that our flicker-free lights, such as the T8 LED tube lights, can refresh at a higher rate than would be noticeable in a 1000 fps capture.

Generally speaking, most older fluorescent tube light fixtures utilized a ballast within them to regulate the power being supplied to the lights. As this is no longer necessary for LED products such as ours that contain internal transformers, some older ballasts are incompatible and can cause performance issues such as flickering.

As such, before ordering, it may be worth ensuring that the ballast within your fixture is within the compatibility list. If they are not, it might be helpful to know that we are looking forward to releasing our own line of LED-Ready tube light fixtures within the next month or so. 

​Additionally, fixtures with ballasts can still be used without lights when a ballast-bypass installation type is used, which is illustrated within the below product installation guide.

 So if I were to use my own lighting fixture (a none waveform fixture) for the "Flicker-Free T8 LED Tube Light" I would need to make sure the ballast in the fixture is on the compatibility list.

That's correct! Though it may be helpful to know that the fixtures linked are integrated and do not require any lights to be installed. These are different from the upcoming line of LED-Ready T8 tube light fixtures, which can utilize our T8 LED tube lights.

Can you recommend any lighting fixture you know has the proper ballast for the "Flicker-Free T8 LED Tube Light?"

Unfortunately, we do not have any specific fixture models that we could recommend at this time. We apologize! 

If I wanted to get the Flicker-Free A19 10W LED Bulb, could I use a standard e26 or e27 socket and still remain flicker-free?

We are happy to confirm that the internal hardware of the A19 bulbs will allow for flicker-free functionality when installed within a matching E26 or E27 base. We have also attached a blog post below which describes the hardware and voltage differences between the two sockets, which may prove to be useful.

E26 vs E27 Bulbs - Interchangeable? Not Necessarily!: https://www.waveformlighting.com/home-residential/e26-vs-e27-bulbs-are-they-interchangeable

Do the " Flicker-Free T8 LED Tube Lights" have single-ended or double-ended power? Can they operate in a single and double lamp fixture configuration?

We are happy to confirm that our T8 LED tube lights can be installed and powered using either single or double-ended power configuration.

As such, please feel free to utilize them within compatible fixtures that utilize either of the above "UL Type B" installation types. The available configurations for that type can be found in the installation guide, which I have provided a link to below.

Flicker-Free T8 LED Tube Installation Guide

What is the difference between the NorthLux™ 95 CRI T5 LED Linear Light Fixture and the D50 5000K T5 LED Linear Light Fixture for Color Matching?

We can confirm that the two products are identical, though they are provided with unique landing pages for marketing purposes. This can be noted by the shared part number, though I do apologize for any confusion this may have caused.

Are both of these lights flicker-free? What is the PWM frequency of these LEDs?

Yes! Both products offer a <1% flicker rate and a 20kHz frequency.

If they are flicker-free, can I use third-party daisy chain cords, accessories, extension cords, etc., and still get a flicker-free effect?

Yes, the flicker-free functionality should be preserved when utilizing a compatible third-party C8 plug cable.

How many units can be daisy-chained into a single outlet?

A total of 70 feet (21 meters) of the linear light fixtures can be safely daisy-chained together.

What do you mean by a <1% flicker rate? At 20kHz frequency, would that mean I can shoot video at a maximum of 40,000 frames per second before seeing the flicker?  

We typically say that our products have a flicker percentage of less than one percent in marketing materials, though the actual flicker rate of our flicker-free products is 0%, with a 0.00 flicker index when tested.

We have attached a link to the spectrum test report for one of our flicker-free A19 bulbs below, for your reference. Upon review of the last page, you will see an example of our test data showing a 0% flicker rate. You will also see that the flicker index is 0.00, as there is an extremely minute variability between the maximum and minimum light output per hertz cycle. As such, we would not expect any visible flicker at that capture rate. 

​

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.

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.

Do the T5 LED Linear Light Fixtures include bulbs and magnetic mounts?

I just placed a large order and then noticed the NorthLux™ 95 CRI T5 LED Linear Light Fixture 4026.2F.50 I had a few questions. 

Does the fixture include the bulb? 

We can confirm that the linear light fixture contains the bulb pre-installed.

For the magnetic mounts, I see they have screws but do these need to be screwed into something to hold the magnets to hold the bulb? 

The magnetic clips are designed to easily attach to the underside of the light fixture, and should not require any screws or additional mounting accessories. These clips are included within the product packaging.

T5 LED Linear Light Fixtures Flicker Data

Does Waveform have any data regarding the flick % of the NorthLux™ 95 CRI T5 LED Linear Light Fixtures? (Or even an educated guess?)

We can confirm that our T5 LED Linear Light Fixtures are flicker-free. 

I do have one more question: is a longer, or additional, extension cord (for connecting two lamps) available for the NorthLux T5 lamps?

While we currently do not have a longer power cord available than the 12” (1 ft) pre-packaged cord, we can confirm that this product is compatible with longer third-party C8 plug cords that could be found at stores such as Home Depot or Amazon.

Difference between NorthLux and D50 T8 LED Tube Lights

I am wondering if you could help me with a few questions about specific products of yours: 

NorthLux™ 95 CRI T8 LED Tube for Art & Studio & D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000) What is the main difference between these two lights? I'd get them in 6500k. Are they both near daylight quality? They are for my workshop. I'd like it as close to daylight as possible. 

Regarding the 2 above lights, what is the footprint size of the light the fixtures emit? How many square feet of light would each tube emit? 

I see that you offer the same quality lights but in a T5 fixture. What is the square footage of light emitted for the T5 fixtures with CRI95? 

We can confirm that the NorthLux™ 95 CRI T8 LED Tube for Art & Studio product and the D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000) are identical products which are provided unique landing pages for marketing purposes. This can be noted by the shared part number of both products. We would like to sincerely apologize for any confusion that this might have caused.

As the footprint size of the light output generally scales depending on the area that the light is filling, it would be difficult to know what the footcandle measurement would be without knowing the dimensions of the space. As such, our lumen estimation calculator tool might prove to be helpful for your planning purposes. By inputting the dimensions and selecting the planned purpose of the space, our web tool will assist in suggesting the right quantity of lighting products to meet your ideal output.

In the interim, we can confirm that each of the products has an 1800-lumen output. Further, the 6500K color temperature option is designed to emit light that is extremely similar to north-facing daylight. Alternatively, our 2ft NorthLux™ 95 CRI T5 LED Linear Light Fixtures have a lumen output of 900, whereas the 4 ft fixtures will have an output of 1800 lumens.

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.

Do you have flicker data on T5 LED Linear Light Fixture

I'm an Australian artist/painter and your lights sound/spec amazingly. Do you have Flicker data/info on these particular lights? Installing these lights on the ceiling, clearly, I'll have to turn the power on and off at the wall, rather than on the ballast itself, I presume this is ok? So the light would be in the on position, with power being turned on and off at the wall. Is that all ok? - How long is the c9-c8 connector that comes with the light? And can the lights be daisy-chained with normal c8-c8 extensions of longer lengths bought off the shelf? 

The NorthLux™ 95 CRI T5 LED Linear Light Fixtures offers flicker-free performance. 

Though these linear light fixture products can be daisy-chained together using the 12-inch (30 cm) included cable or via third-party C8 two-prong plugs, please note that these items are not designed to be configured with wall switches or dimmers. As such, these products might not be ideal for ceiling-mounting in all installations.

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.

LED Lights for the Quilt Fabric Storage Area

I need a light system in my wife’s quilt fabric storage area. She needs to shorten and March by overall and small amounts of color. I am thinking of five of these ABSOLUTE SERIES™ LED Linear Module - 99 CRI - 1 ft / 280 mm MCPCBone. One on the ceiling and two down the sides next to the jamb. I am open to other suggestions. I would need to know the other accessories required to string them together. The colors she matches are sometimes hard for me to see. 

Based on the information provided, it does appear that the ABSOLUTE SERIES™ LED Linear Module - 99 CRI - 1 ft / 280 mm MCPCB product could be a good fit for your installation.

Regarding installation instructions, we have a great page on our website which describes the process in depth and includes links for required accessories, which I have linked below.

Assembly Instructions for LED Modules: https://store.waveformlighting.com/pages/assembly-instructions-for-led-modules

As an alternative, you might also be interested in our NorthLux™ 95 CRI T5 LED Linear Light Fixture product. This item features a high CRI, and a low profile, and can be very easily installed without requiring wiring or power supplies.

I like the tube alternative. How long are the connecting wires between the tubes? Can I order another plug wire? Is there a disadvantage to getting the 6500 vs 5000, you are out of stock of the 5000 4’ tubes.

We are happy to confirm that the Linear Light Fixtures can be connected end-to-end using the integrated plugs. Alternatively, you may choose to utilize the included daisy chain cord for connecting the fixtures, which is 30 cm in length.

Though we do not have longer daisy chain cords available, you will likely be able to find a longer third-party option quite easily as these products utilize the standard 2-prong C8 plug.

If a guide for color temperatures proves to be useful in your planning, I have provided a link to a blog post from our website below.

Difference Between 5000K and 6500K Bulbs:

Proper LED Products for Art Studio Lighting

I am an artist and have been on a long quest for proper lighting for my easel that will not distort colors. I have an east-facing window. I have read through much of your fantastic website, which is well done and very informative. I have a few questions:

Noting that I have an east-facing (not north) light source and think I would like the dimmable NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio Edison bulbs would you recommend the 5000k or the 6500K?

​Both color temperatures should work well for your needs; however, 6500K is generally a better fit for north-facing windows. As such, you may prefer the 5000K for your east-facing window setup. 

​Please see below for additional insights from our blog:

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

​What would 800 lumens equate to in incandescent wats? I couldn’t find a scale to show me how lumen output compares to incandescent wats, which is what I am used to when comparing light brightness. If I get two of these which are 800 lumen or 60W halogen will these give me essentially 1600 lumens on my painting surface (depending on the distance of course)?

​800 lumens is approximately equal to a 60-watt incandescent bulb. You are exactly right that two bulbs would add up directly to 1600 lumens and provide twice the brightness.

​Do keep in mind, though, that incandescent lamps emit a much warmer 2700K color tone, so it can be a bit difficult to compare brightness when discussing daylight-calibrated bulbs. Nonetheless, it is certainly a good ballpark estimate when it comes to relative brightness levels!

​There are so many different light sources to consider when creating a painting: reference source (photo, print, iPad, computer, life), natural outside light (weather dependent), studio light (intensity, color, placement including projection on both paintings and palette), photographing final work for publication and giclee printing, and gallery or home viewing of the finished painting. I read on your site that a device’s screen can emit blue light. So, is it probable that this is the first point where color can become distorted?

​That is exactly right - most digital displays will be calibrated to D65 (6500K) but of course, depending on the level of sophistication and quality, the calibration may or may not be accurate. Even natural daylight, as you mention, can change depending on the weather and season, so that can be difficult to navigate as well.

​That is where high-quality studio lighting comes in and can provide some consistency and accuracy. I have seen some customers even block out their windows and replace them with our lamps because the natural lighting was too inconsistent due to changing weather and time of day. Ironically, the only way to ensure consistent lighting would be to only use a high-quality, full-spectrum artificial light source, day and night.​

​If an artist is working primarily from an iPad should they choose the 6500K light because it matches the blue light from the iPad or goes with the 5000K because it will color compensate?

​Unfortunately, it does not seem that Apple likes to publish technical data about their iPad product and I was unable to confirm if their screens are calibrated to D65 (6500K). That being said, I believe almost all digital displays are calibrated to D65, so there is a strong likelihood that the iPad product line is also D65 calibrated.

​If so, the 6500K light source will be a better match to the iPad, since as you mentioned correctly, the 5000K will be a bit "warmer."

​(Here is some additional information on D65: https://www.waveformlighting.com/color-matching/what-is-d65-and-what-is-it-used-for)

​So many questions, but your team seems to have the technical expertise to answer them and for the various combinations of light. If these bulbs and your recommendations turn out to be the Holy Grail of Art Studio lighting, I would like to share it or see it as a feature article or workshop with my local, national, and international art society membership because many artists seem to struggle with this lighting issue because it is such a science complicated by the ever-changing variety of bulbs and diverse lighting comparison scales. Also, would you have any discounts available for our membership? 

We would be honored to have you share your experience working with our products! As a general policy, we do not offer any group or membership discounts, but I would be more than happy to share the opportunity with our team at that time.

Are the NorthLux 95 CRI T8 LED Tube Bulbs Dimmable? 

Are these NorthLux™ 95 CRI T8 LED Tube dimmable? Are you aware of any clamp-on, swing arm, or drafting table-style fixtures that would accept this 4' T8 bulb? I have a large 63" wide drafting table which I use for drawing/painting. I am looking for two clamp-on swing-arm style lamps which I can position on each side of my table to illuminate the whole surface evenly with one of your 5000k high CRI lamps. But am having difficulty finding the right fixture/lamp combination. 

Unfortunately, the NorthLux™ 95 CRI T8 LED Tube for Art & Studio products is not compatible with dimmers. Though we would love to recommend a compatible lighting fixture for your drafting table, we are unaware of any products which match the description provided at this time.

That being said, our NorthLux™ 95 CRI T5 LED Linear Light Fixtures might be of interest to you as well. Though these products are also not dimmable, they can be conveniently installed, are available in 5000K, and do not require fixtures or power supplies for functionality.

Please feel free to reach out if we can provide any further product information or recommendations, and we would be glad to help!

For your T5 Linear Fixture, how would you propose those be installed for my application? Do you have compatible clamp/swing arms to hold two or three in a desk lamp configuration? Or some other way to hold and manipulate them for drafting table use?

As the linear light fixtures can be linked together end-to-end to share one power supply, I imagine that a connected set could be mounted together as one length to an adjustable swing arm above the drafting table. 

​If a stable arm was found, we believe that the included mounting accessories could make such an installation easily re-configurable. Unfortunately, we do not have a specific clamp or swing arm that we could recommend.

However, you might also be interested in installing a length of LED strip lights onto a fixture above your drafting table. These products are compatible with dimmers and can be mounted within fixtures such as our Aluminum Channel for LED Flex Strip products. I have linked to a great article from our website below, which explains how to get started with LED strip light products.

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

How is the CRI of the LED strips affected when mounted inside the channel with the diffuser? 

Based on our experience, the diffusers do not affect the CRI values of the products mounted within. Further, we have found that the effect that this diffusor will have on color temperature is small, likely resulting in a difference of +/- 25 kelvin.

T5 Linear Light Fixture to Replicate Sunlight for an Apartment Space

I have recently moved into an apartment that has plenty of daylight but no direct sunlight. I wonder if the NorthLux 95 linear strips, placed along the floor molding behind my couch and beaming upward would replicate sunlight? 

Based on the details provided, it sounds like the NorthLux™ 95 CRI T5 LED Linear Light Fixtures could be a great way to illuminate your space!

These products are very easy to install, require no additional accessories or power supplies, and are well-suited for washing a wall in light. Further, multiple units of this product can be daisy-chained together for convenient powering.

Does each light of 4-pack T5 Light Fixture has its own set of accessories?

Does each light in the 4 pack have its own set of accessories? Are there (4) 2-prong plugs, so I can install them in 4 different locations?

We are happy to confirm that each unit within the 4-Pack of the NorthLux™ 95 CRI T5 LED Linear Light Fixture product contains a dedicated set of accessories, including power cables.

LED Light Fixtures for Art Studio Lighting

I have a 13' X 21' painting studio with a two story 12/12 pitch ceiling with two skylights on the 13 foot north end.

The dimensions are a great starting point and I appreciate you providing this data. I plugged in dimensions of 13 x 21 x 11 ft into the Lumen Estimation Calculator, which recommends a total of 22,600 lumens to meet the brightness needs of an art studio (approximately 80 footcandles).

​The target of 22,600 lumens should be our overall guiding target in terms of brightness, so this will be an important number to keep in mind!

​I need studio lighting.

The two crucial aspects of color quality when it comes to studio lighting are color temperature and color rendering. In terms of color temperature, daylight-calibrated color temperatures are best for art studios. We offer both 5000K and 6500K as color temperature options, and these values roughly correspond to noon-sun daylight and north-facing daylight, respectively. Additional information is available in our blog post below:

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

​In terms of color rendering, higher color rendering ensures accurate color representation. For painters, for example, this means that when you observe a particular paint color during the daytime, the same paint material appears the exact same during evening hours when viewed under a high CRI light source, but may appear different when viewed under a low CRI light source. This will obviously cause issues with color judgment and consistency.

​Track lighting is installed on two 13' overhead beams centered in the space at 11' up. I need overall work light. Do you recommend hanging shop lights above the beams (how many) or using linear light fixtures attached to the beams (how many). Would linear lights provide enough light?

Going back to our brightness target of 22,600 lumens, we can back-calculate the following:

​Shop Light Fixtures @ 4200 lumens each = 6 fixtures

T5 Linear Light Fixtures (4-ft) @ 1800 lumens each = 13 fixtures

​According to these calculations, either of these options will provide sufficient light across your space. You could, of course, even do a little bit of mixing and matching with fixture type and installation location to increase the amount of brightness in certain areas of your studios where it is most needed.

​I have an electrical box in the ceiling on both side above the track beam. These aren't dimmable so I don't want to be blasted out either. What do you recommend? 

Unfortunately you are correct in pointing out that these fixtures are not dimmable. The best alternative solution we can suggest here would be to connect the fixtures on separate light switch circuits so that you can manually choose between full and partial brightness. (This may be especially useful since you may have sufficient daylight coming in during the daytime from your skylight).

Recommended quantity of LED Lights in building an Art Studio

I am building an art studio. It is 3000 square feet. I am dividing it into two distinct spaces: the shop with a full complement of woodworking machinery, and a clean studio for drawing, painting, and other quiet work. 

I have calculated that I need 16 of PN:4025. Is this the proper fixture and quantity?

​I've run these numbers in our lumen estimation calculator and received a recommended brightness level of approximately 65,000 lumens. Since each of our PN 4025 shop light fixtures emits 4200 lumens, my math also works out to approximately 16 lamps, which lines up perfectly with your calculations.

​Is there an alternate fixture for the purpose?

​I do not believe that any other fixture options would be superior, except for our T5 linear fixtures, if these are perhaps a more preferred option from an aesthetic or layout perspective. I have included the link to the product below:

​Similarly, we offer a T8 LED tube light which can be used in traditional fluorescent fixtures. It does sound like you are building a new structure, such that utilizing previous-generation fluorescent fixtures would not make much sense unless you had a particular reason for doing so.

​The color quality at 5000K / 6500K and 95 CRI are identical across all of these options so that should not affect the decision in terms of form factor.

​Now on to the shop side of the studio. I am not sure of the lighting level appropriate for a woodworking space. Is it 30fc (simple manufacturing and industrial) or 40fc (like a classroom)? I have been planning on using 25 at 4000-lumen LED fixtures made by Hyperikon. These lights are 84 CRI and produce 40fc over the area. They are under $20/fixture. Is there justification for purchasing your lighting for the shop side of my studio instead of theirs?

​This is a bit difficult for us to provide any definitive guidance on the 30 or 40 footcandles would depend on the exact level of precision needed, as well as the type of wood, along with personal preference on brightness.

​It is certainly possible that 30-footcandles just don't provide enough brightness, but I would not think that going with 40-footcandles would be "too bright" (i.e. uncomfortable) by any means, so the worst-case scenario here would be that we are over-specifying in terms of brightness.

​As with the brightness question, the higher CRI rating may or may not be necessary depending on the type of woodworking. Some of our customers find that the ability to make very critical color observations during woodworking (perhaps during staining or other visually demanding processes) justifies the additional cost. On the other hand, if color accuracy is less of a concern, I would perhaps recommend staying with the 84 CRI fixtures as that would be more than enough to simply "see" what you are doing and complete basic tasks.

​Do I have a good amount of light coverage, or would I need more? 

I'm not sure what the dimensions of your woodshop will be, but the 25x Hyperikon fixtures would provide you with 100,000 lumens which would be sufficient for approximately 2200 square feet of coverage.

Do you have longer connecting cords to daisy-chain multiple fixtures?

I am thinking of ordering 4 more fixtures. The connecting cord that connects one set of lights to another is only about a foot long. Anyway, you have longer connecting cords from one light to another. 

While we can confirm that the power cord packaged with the T5 LED Linear Light Fixture is only 1 ft in length, we, unfortunately, do not have longer power cords available at this time.

However, it might be helpful to know that third-party 2-prong plug power cords can also be used if a longer length is preferred for your configuration.

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.

Do the T5 linear fixtures come with any reflector covers? 

Does the 4026.2F.50 come with any kind of reflector shield or something else to direct the light at a more downward angle? I am thinking of something similar to what is seen in a hanging shop light fixture. 

The T5 linear fixtures (PN 4026.2F.50) do not include any reflector covers, and the light distribution is wide and dispersed. As such, if you are looking for a lighting solution that provides a more direct light output, these T5 fixtures may not be the best solution for you.

One alternative would be to consider our LED strip lights, which do not include any diffusers and may be well suited for a DIY installation. The LED strip lights have a 120-degree beam angle and can be further adjusted with secondary optics and reflectors.

Would you happen to know how far the connector protrudes from the side of the case? I see that there seems to be a plastic (daisy-chain) connector that protrudes from the case opposite the power switch.

​We, unfortunately, do not have an official specification on the protruding distance but estimate it to be approximately half an inch.

High CRI and R9 Lighting for Textiles and Leather

I make handbags that incorporate textiles and leather. I need to get accurate color when photographing my pictures. I am taking pictures myself and am not a professional photographer. Is there any LED lighting that you can recommend? I’m taking pictures indoor. I also have an adapter that can fit LEDs into a soft box. I’ve tried natural light but I’m trying to get consistent pictures for my online website. 

Based on the details provided, there are a few products that we might recommend depending on your ideal installation method.

The primary product that we might recommend is the 99 CRI ABSOLUTE SERIES™ LED Flexible Strip product. This product feature light which is virtually indistinguishable from natural daylight, which could prove to be useful with your photography.

Alternatively, in the event that you would prefer to use traditional light fixtures, we might recommend our NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio products. However, please note that this product is currently backordered.

As a final recommendation, our NorthLux™ 95 CRI T5 LED Linear Light Fixtures can be easily mounted in multiple configurations, and contain integrated lighting within the product housing, which reduces the amount of required accessories.​

Is your T5 LED Linear Light Fixture dimmable?

NorthLux™ 95 CRI T5 LED Linear Light Fixture 4026.2F.50 Are these dimmable? If not, do you sell any that are?

Unfortunately, our linear light fixture products are not compatible with dimmers.

However, we're happy to confirm that our LED strip light products are compatible with dimmers if they are a viable alternative for your installation.

D50 or Northlux: T5 LED Linear Light Fixture for PC Monitor Lighting

I would like to purchase a 4ft T5 LED Linear Light Fixture to light a pc monitor. Do you recommend the D50 or the Northlux? How long is the power cord? 

We can confirm that 5000K NorthLux™ 95 CRI T5 LED Linear Light Fixture item is the same product as the D50 5000K T5 LED Linear Light Fixture for Color Matching (ISO3664:2000) item. This can be noted by the shared part number of both products, PN 4026.2F. 

We do apologize for any confusion this may have caused, as these products are listed on multiple pages for marketing purposes.

As such, you can expect identical high performance from both items in your installation, including D50 compliance. Both of these products also contain a power cord which is 12 inches in length (30 cm).

What is the maximum number of T5 LED Linear Light that can be daisy-chained together?

I noticed these fixtures are daisy-chainable and wondered what the maximum number of fixtures could be connected this way.

The NorthLux™ 95 CRI T5 LED Linear Light Fixtures can be daisy-chained together for a total of 70 feet. As such, one could daisy-chain 35 units of the 2 ft version, or 17 of the 4 ft version together.

Can both lengths be interlinked? ie. can I connect 4ft and 2ft segments in the chain?

We're happy to confirm that the 2 ft and 4 ft Linear Light Fixture units can indeed be combined.

Do you have a commercial high-bay/suspended-type lights?

We are building an addition to our brewery and would like to know if there are commercial high-bay/suspended-type lights for a taproom and brewery space.

Our high CRI and full spectrum lamps sound like. a great option for lighting up a brewery and providing a high-end lighting atmosphere.

For high-bay installations, the first aspect would be to consider what type of fixture you would like to utilize for the space. If, for example, you have existing T8 fixtures, our T8 LED lamps may be a great option for such retrofit applications: https://store.waveformlighting.com/products/centric-daylight-full-spectrum-flicker-free-t8-led-tube-light

Alternatively, if you do not have any fixtures in place (or if this is for a new build), you may want to consider our hanging shoplight fixtures or our integrated T5 fixtures. These products have LEDs integrated into the fixture, so there is no need to purchase the fixture and lamps separately. Please see below for additional product information:

LED Lights Recommendations for Digital Photo Studio

I'm converting a utility room in our garage to be a dedicated digital photo studio. As such, I know I need much more controlled/accurate lighting. Note, that I do not plan to shoot photos/video in the room, just edit, evaluate, and display.The skylights have remote-controlled blackout shades. My initial thoughts about your products are as follows:

I was thinking of using your 16' LED strip mounted in an aluminum channel on the ceiling ridge, e.g. Centric Daylight strip 5000K. For the LED strips, do your aluminum channels have a system to interlock end-to-end or would you recommend other types of aluminum channels for reasonably diffuse light?

While the linear light fixtures could allow for an easier installation than the LED strip lights, the linear light fixtures are not dimmable. As such, your space might benefit from the LED strip light products, which allow for dimming functionality.

Further, the aluminum channel products unfortunately do not feature the ability to interlock. However, there may be third-party products available elsewhere which would allow for a continuous length of mounted LED light strips for installation along the trusses of the room.

I was thinking of using your FilmGrade Hybrid LED strip mounted in your corner aluminum channels mounted under the bottoms of the trusses in the photo to illuminate the right side wall where I would hang/display prints. How accurate are the hybrid strips in simulating various color temps, etc.? Equally important, what's a simple solution for a controller that would allow me to specify the desired color temperature and it would set the appropriate LED values? Is this doable, what would you recommend?

The FilmGrade™ HYBRID LED Strip Lights could be a great option for your space, and I am happy to confirm that this product can be used to simulate any color temperature between 3200K and 6500K by adjusting the intensity of each color temperature.

However, it might be valuable to know that a LED strip light product featuring a single dedicated color temperature is able to emit more light per foot than the individual colors of the HYBRID LED Strip Lights are able to. For example, the HYBRID LED strip lights emit 225 lumens per foot, per color, whereas the single-color FilmGrade™ WHITE LED Strip Lights emits 450 lumens per foot.

This product can be controlled using several different methods. Though the easiest implementation would likely be to utilize a color tunable LED controller, which would allow for you to easily adjust each color point. The below article contains detailed descriptions for each configuration method available for the product.

How to Connect Hybrid CCT Tunable LED Products: https://www.waveformlighting.com/film-photography/how-to-connect-hybrid-cct-tunable-led-products

You sell your T5 Linear light fixtures (D50) in 4 ft. I was thinking of using a couple of those to set up a dedicated print viewing station. Your website says they are out of stock but will ship on 12/14. Is availability still accurate as I would like to go ahead and order them to start experimenting?

We can confirm that the 5000K 4-ft NorthLux™ 95 CRI T5 LED Linear Light Fixture product is currently expected to be available by December 14th. In the event that you would like to place your order prior to that availability date, we would process the shipment as soon as the items become available.

Do all of your 5000K lights actually meet D50 spec or only where specifically indicated?

Not all of our 5000K color temperature products are designed to be compliant with the D50 standard. However, if you had a specific product in mind, I would be happy to review the item to check for D50 compliance.

Anything else you would advise or suggest that I consider?

Regarding installation suggestions, the primary consideration which comes to mind would be to test the LED strip light products within the space prior to cutting the product into segments or installing them completely, as we are unable to accept returns for these products as soon as they have been cut or altered.

Our second suggestion is to keep in mind that the FilmGrade™ HYBRID LED Strip Lights requires a 24V power supply.

Third, the HYBRID LED Strip Lights product has a maximum run of 32.8 ft, and draws a variable amount of power per foot depending on the color point adjustment. Details regarding this can be found on the product specification sheet. As such, you may want to consider a power supply which is capable of outputting enough power to accommodate the power draw needs of the lengths of your installation.

On the FilmHybrid LEDs, I saw the referenced setup with the two dimmers. But to use that, I need to figure out the dimmer settings that correspond to different Kelvin temperatures. I'm assuming to do that I would need to have a spectrophotometer that can measure incident light which I don't have. Is there another 3rd party solution that you could recommend that wouldn't be too complicated or expensive that would allow me specify the color temp and then set the appropriate values on the two LED channels of the hybrid film strip?

Any 3rd party aluminum channel manufacturers you recommend that might have interlocking sections? I'm still going to take a look at yours as well.

Unfortunately, the dimmer uses an analog dial to control the relative brightness levels of the two channels, so there is no way to digitally map the two output levels to a specific color temperature level. You may want to think of this as being similar to a traditional shower faucet, with one for hot and one for cold, without the ability to set a specific water temperature.

We are not aware of any third-party products or solutions that could incorporate our LED strip light to achieve the lighting controls you are looking for, but do hope to be able to offer such solutions in the near future. For the time being, we may recommend searching for cinematography and photography lighting products such as those manufactured by ARRI or Kino Flo, although these will likely be a much higher price point.

I've got a few questions on your 24V dimmable transformer that I purchased:

Is this designed to be driven at 100% rated load (96W) for a prolonged period of time? Is there any issue with splicing a pigtail and plugging it into an outlet (that has an AC dimmer upstream)? Is there a minimum load requirement on the transformer? Any issues if there is a GFI on the circuit?

The 24 volt dimmable power supply load is de-rated at 100% (full 96 watt capacity) until ambient temperatures exceed 105 F. Maximum allowable ambient temperature is 140 degrees F, at which the power supply output load is de-rated to 60% (59 watts capacity).

​We do not maintain a minimum load requirement on the power supply unit, but all dimmer tests are performed at 85% load.

With respect to your questions regarding installation through a wall outlet and the use of GFI components, I would consult with an electrician for further recommendations. From what I understand, there may be code compliance issues arising from:

From a pure electrical standpoint, I do not believe there would be any performance issues, but such installation methods would be beyond the scope of our safety and reliability assurances.

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!

LED Panel Lights for Home Office Lighting

The space my wife and I use as a home office was originally designed as a sun porch. There's a single, small fixture in the middle of the room that provides very poor lighting to our desks. I was thinking of installing a surface mount LED panel (because the ceilings are relatively low) over each desk, but it's difficult to find LED panel lighting with >80 CRI. I'm looking for something that mounts close to the ceiling, is dimmable, and relatively long (to provide even lighting across a desk).

We unfortunately do not have any LED panel lights, and the requirement for dimmability makes this quite challenging based on the offerings we currently have available.

If you're willing to forego dimmability as a requirement, our T8 LED lamps housed in an appropriate ceiling fixture, or our T5 linear fixtures, could potentially be viable solutions for you. Both are available with 95 CRI and provide excellent light quality that should work well for a home office.

​I've included product links for these products below:

Overhead LED Lights Fixtures for Dental Lab Lighting

I have a dental lab and want to use overhead lights to create natural light to match shades for teeth on my bench top. I have no fixture but I need to get one or more. It would flush mount or hang. Ceiling is 70 inches above bench top. 

Our 95 CRI / full spectrum light sources are likely to be a great fit for the application. 

Below are two fixture products that may fit your needs well. Please let us know your thoughts:

NorthLux 95 CRI T5 LED Linear Light Fixture for Bias Lighting Solutions

I have been searching for bias lighting solutions for a 77-inch flat-panel tv. I placed the NorthLux™ 95 CRI T5 LED Linear Light Fixture in my cart to purchase but I noticed you have specific lights at a higher price point for flat panel applications. Will the item I referenced work behind a TV or do I need to stick with bias lights?

The NorthLux T5 linear fixtures, if you've selected the 6500K color option, should work perfectly for the bias lighting application. The 6500K color point is calibrated to the same D65 color point that is needed for bias applications, and will match the color calibration used in TV displays.​​The primary advantages of the dedicated bias lighting LED strip light product are the lower profile and dimmability (if paired with a dimmer). If neither of these features are crucial for you, the T5 linear fixture sounds like a great fit for you

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!

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:

Light Fixtures for Wall Wash Lighting in Dropped Ceiling

I am designing lighting for artwork in my remodel. I have to use a dropped ceiling so I need lights that can be installed in the ceiling. I can only find light bulbs. Do you sell light fixtures to be installed in ceilings to light up artwork?

Unfortunately, we do not currently sell light fixtures which can be installed directly into ceilings.

However, we do sell T8 LED tube lights, such as the NorthLux™ 95 CRI T8 LED Tube for Art & Studio product, which are designed to be installed within ceiling light fixtures.

NorthLux™ 95 CRI T5 LED Linear Light Fixture CRI Rating

On the specs for the 4ft NorthLux Linear Light Fixture 5000K, it says it's only 90 CRI. Is that correct? I am replacing the ceiling lighting of my studio: four 48" two-bulb fluorescence light fixtures. Would four of the 4ft Linear Light Fixture 5000k be enough?

We're happy to confirm that the 5000K NorthLux™ 95 CRI T5 LED Linear Light Fixtures actually have a CRI of 95+. However, these products do have an R9 value of 90+, which may be what you are referring to. Based on our review of the most recent Photometric Report for this product, the CRI is listed at 97.4, and the R9 is listed as 95.

​For further photometric information, here is a link to the product report: https://www.waveformlighting.com/photometrics/TR_4026.50.4F.pdf

Based on the description provided, it does sound as though four of these products should work well for your space! Further, the Lumen Estimation Calculator tool on our website may also be valuable for planning the number of lighting products for your space.

However, please know that we offer a 30-day return policy. If these products do not work well for your space, we would be more than happy to issue a return label for an exchange or a refund.

Do you have a D50 5000K and 4000K in 90+ CRI?

We are interested in your D50 5000K model 4026.2F.50 light fixture, T8 tubes model 4024.50.4P, or perhaps the Flexible Strip 7101.50 mounted to the aluminum channel and quite possibly a combination of all. Key is D50 5000K 90+ CRI. Also looking for something similar in 4000K

​The ABSOLUTE SERIES is not available in 4000K, but the T8 lamps and T5 integrated fixtures are available in 4000K. The part numbers are 4024.40 and 4026.2F.40, respectively.

We are concerned about UV and IR from the above lamps. I realize output in these regions would be low, but is there a way to quantify what level is considered damaging to artwork, photographs, documents, etc.

We do not have any data on hand for this, but I would expect that this can certainly be quantified in irradiance units (e.g. mw/cm2) accompanied by a wavelength range (e.g. UV-A), or 340-400 nm). If your customer has any specific requirements in terms of irradiance, that would be very helpful for us to verify compliance; if not, a starting point may be showing them our photometric reports which show essentially no energy emission in the UV and IR regions.

What type of power cord used in NorthLux™ 95 CRI T5 LED Linear Light Fixture?

I just ordered a few of the "NorthLux™ 95 CRI T5 LED Linear Light Fixture", and the pictures make the power cord look really short. I was wondering what kind of power cord they use, so I can order a longer one.

We can confirm that the NorthLux™ 95 CRI T5 LED Linear Light Fixture uses a two-prong US-style, C8 connector plug. In case it proves to be useful, the power cord that comes with this fixture has a length of 12 inches (30 cm).

More information regarding the product and the included accessories can be found at this link: 

https://www.waveformlighting.com/datasheets/CS_4026.pdf

Power and Daisy Chain Cord Length of NorthLux™ 95 CRI T5 LED Linear Light Fixture

I am interested in the NorthLux™ 95 CRI T5 LED Linear Light Fixture but would like to know how long are the power cord and daisy chain cord. 

The power cord for the NorthLux™ 95 CRI T5 LED Linear Light Fixture is 12 inches in length (30 cm), and the daisy chain cord is also 12 inches in length (30 cm).

We have recently updated the specification sheet for this item with this information, which can be found at: https://www.waveformlighting.com/datasheets/CS_4026.pdf

T5 LED linear fixtures Power and Daisy Chain Connectors

I live in the UK and I'm thinking of ordering some of the T5 LED tubes. Questions:

1) Is the power connector (LED end) a standard fitting? I don't want to run a UK-US adaptor at the wall and want to make sure I can buy a generic cable. 

2) How long are the daisy chain cords? 

3) Is the Northlux 5000k T5 linear light fixture the same thing as the D50 5000k T5 linear light fixture (I note the part number is the same, so assume so but want to double check). 

4) What happens if anything is dead on arrival? Just wanted to check, with me being an international customer.

Our T5 LED linear fixtures sound like a great option for you.

​The included cables for our fixtures are the two-prong North American plug types, but if you would like to source your own cables to fit UK-style electrical outlets, you should be able to do so using a standard C8 ("figure 8") input wire.

The D50 5000K T5 linear is indeed the same product as the NorthLux T5 linear (PN 4026), listed on separate pages for slightly different applications, though the requirements for ultra-high color quality remain the same for both!

Finally, please know that we stand 100% behind our products, and should there be any issues during the first 3 years of usage, we will gladly send a replacement free of charge, including any international destinations. Please see our warranty policy here.

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.

Is the NorthLux™ 95 CRI T5 LED Linear Light Fixture dimmable?

Unfortunately, the NorthLux™ 95 CRI T5 LED Linear Light Fixture is not dimmable.

That being said, we do offer other products which are dimmable, such as the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio. Depending on your installation, these products might be valuable alternatives.

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.

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:

Recommended bulbs for Studio Lighting

I need assistance with LED lights choosing the correct bulbs for my art studio and how should setting up my lights for my application. I want to be able to render pencil/charcoal/and paint with the lights. I will be using 8ft ceilings unfortunately but do not currently intend to do many large paintings so hopefully, I will have enough height. I was personally thinking of your 5000K LED Art Studio Tubes or the LED 5000k bulbs but I was not sure if tubes or bulbs made more sense. And if I get either the tube or the bulb what fixtures to mount them with and what wiring info? 

It does indeed sound like our NorthLux LED products with 95 CRI and daylight-calibrated color temperatures will be an excellent option for your space.

You are correct that you're in perhaps one of the more tricky stages of planning your lighting, and we'd be more than happy to offer some recommendations.

​The first question would be to determine what kind of fixtures (if any) you would be interested in utilizing in the space. For BR30 lamps, for example, you will require residential/commercial style recessed can lights, which typically will go directly into the ceiling, meaning there will be some construction and electrical work needed.

​With the tube lights, you can also consider similar ceiling fixtures such as 2' x 4' fixtures, but there are also options such as strip light fixtures and other ceiling mount fixtures that won't require as much involved construction or electrical work.

One of our new products that might be most convenient and the best fit for you would be our integrated T5 LED linear fixtures. These lights have the same 95 CRI NorthLux LEDs inside, but also include screw or magnet-based mounting systems, which means that you do not need any additional accessories or electrical work. They simply plug into a wall outlet, and can also be daisy-chained to connect multiple fixtures.

I've included the product link below - please let us know your thoughts!

Do you have to daisy chain the end of the light to end or can you use a jumper wire to set the lights up parallel to each other? 

You can daisy chain them end-to-end, or they can be connected using a daisy-chain wire. See below:

Have you had the artist install the NorthLux 95 CRI BR30 LED bulbs in adjustable lamp track lighting? Like gallery Style? Would you recommend a track lighting system or a tube light system for an oil painting studio with an 8 ft ceiling?

The BR30 lamps are generally used in ceiling fixtures (e.g. recessed can light) and not track light fixtures. One of the concerns is that the BR30 beam angle is very wide and spread out, making them less suitable for track light fixtures which generally are designed for narrow beam angle spotlights generally seen, as you mention, in gallery settings.

For art studios, the tube lights would definitely be a great option, as they can provide full and evenly distributed light coverage. 

To get a sense of how much light you will need, we would recommend using our Lumen Estimation Calculator, which can be found at the link below:

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

Do you think if you used the BR30 bulbs with the track light fixtures you could get a wider distribution of light from the track light system giving you the wide soft light without hotspots but also being very adjustable in where you direct the lights? 

If adjustability is an important feature, the track system may indeed work well for your needs! The LED strip lights are quite permanent and fixed in place, so that would definitely be a big downside.

Is it possible to direct wire the NorthLux™ 95 CRI T5 LED Linear Light Fixture?

Is it possible to direct wire this fixture, preferably from the middle of the backside. I have a 2ft fluorescent fixture this would replace, and it is direct wired through the back of the fixture.

Our T5 fixtures do not come with any direct-wire accessories, but if you are comfortable making the modifications needed to convert the wire plugs into a hard-wired installation, there should be no concerns from an electrical compatibility standpoint.

​The only concern I have is that the wires do need to plug in from the ends, so depending on the exact layout or dimensions of the fixture, the 2-ft versions of our T5 fixtures may exceed the allowable dimensions of your fluorescent fixture.

Do you have an 8ft LED grow tube for growing romaine?

I'm looking for an 8ft, and a 6ft LED grow tube ideal for growing romaine, spring mix, and other quick growing items. We need 48-8ft bulbs, and 12-6ft.

Unfortunately, we do not have any 8-ft or 6-ft bulbs. One recommendation, however, would be our T5 linear fixtures which are modular and can be combined to create various lengths. 

Since they are offered in 2-ft and 4-ft variants, both the 8-ft and 6-ft lengths can be created with the various length combinations.

Below is the link to our "artist" series, for which we will be launching a comparable version for horticulture but in the same dimensions and form factor:

Need assistance selecting LED lights for painting and sculpture studio

We are interested in utilizing your LED lighting products and are searching for assistance in the selection of proper lighting for a painting and sculpture studio.

We had anticipated that we would utilize LED tube lighting flush with the ceiling primarily for our working lighting. What would you recommend?

We offer numerous full-spectrum, daylight-calibrated LED lights that would be an excellent fit for your painting and sculpture studio.

If you are seeking an LED tube lighting solution, our NorthLux™ T8 LED tube lights would be your best bet. These lamps work in existing 4-ft fluorescent fixtures with compatible or bypassed ballasts. If you prefer not to worry about fixture compatibility, or you need to purchase new fixtures for a new studio construction project, these LED tube lights can also be used in our LED-ready T8 fixtures.

Alternatively, you may also want to consider our NorthLux™ LED shop lights and T5 linear fixture options. These alternatives offer the same 95 CRI, daylight-calibrated light quality, but depending on the aesthetics and wiring requirements, may also be viable options.

Lighting up a garage with no windows

I am looking to light up a garage with no windows. It is horrendously hot here in the summer and I want to be able to work in my garage with the doors closed, with the air-conditioning on. Looking into high CRI lighting so that it is nicer in there with good quality light.

The summer heat issue is totally understandable and it sounds like high CRI lighting is definitely a great solution!

For starters, LED lights emit far less heat than fluorescent and incandescent lamps, so regardless of which LED product you ultimately install, you will certainly be helping to keep your garage cooler, and you'll also be able to double-dip on electricity savings as your air-conditioning unit will not need to work as hard.

For garage lighting installations, our 95 CRI LED shop lights have been some of the most popular. Below is an actual installation from one of our customers, courtesy of Mike Fitzpatrick from Liquid Audio.

The LED shop lights are designed to be hung using the included hanging chains, and plug into any electrical outlet, so these are a great option if you're looking for some highly focused light output without having to perform any wiring work. The daisy-chain capability of these lights may also be an added benefit.

Another option would be our 95 CRI T5 linear fixtures. These fixtures also plug into any electrical outlet and can be daisy chained, but are designed to be mounted directly using the included screw or magnet mounts. In terms of aesthetics and installation, these offer a more slim and compact footprint.

Below is an actual customer photo from one of our customers, courtesy of Jimmy Sig.

Finally, if you have existing fluorescent lamp fixtures, our 95 CRI T8 LED lamps may be the most straightforward and low-cost solution. These lamps can be used to directly replace the 4-ft fluorescent lamps currently in your fixture. You'll see approximately the same quantity of light (brightness) but you'll immediately notice the improvement in the quality of light!

This is a great option if you already have the fixtures, as you won't need to perform any extra installation or rewiring work (unless the fluorescent ballast is not compatible with our lamps), keeping both fixture and labor costs down. The added benefit is that if you already have fluorescent lamps in place, you'll have a rough idea of the light distribution and brightness so you won't need to worry as much about fixture placement and modifications.

Hard-wiring LED T5 linear fixtures

I'm looking to install your LED T5 linear fixtures to replace some fluorescent lamps in my office. I plan on removing the fluorescent lamps as well as the ballast. Would it be possible to hardwire this product into my fluorescent fixture?

While the product does not include any hard-wiring components and instead includes a regular two-prong plug wire, if you are able to modify the wire connection, the lamps can be connected directly to line voltage wires in a fluorescent fixture without any issues from an electrical standpoint.

You will, of course, need to ensure that the fluorescent ballast is removed or bypassed as the LED T5 linear fixtures are not compatible with any fluorescent ballasts.

For any electrical code compliance questions, we would recommend consulting an electrician for further assistance or recommendations.

Mounting lights onto a window with no incoming light

I currently have a window that does not have any natural light, because it faces a wall just 1 inch away. I'm hoping to simulate natural light with one of your lighting options. What do you suggest?

Our full spectrum lighting options sound like a great solution for your situation.

In general, our 4000K or 5000K products with 95 CRI will provide you with the best simulation of natural daylight. Our CENTRIC DAYLIGHT A19 bulbs fit into standard screw-base sockets and maybe a great, straightforward option for you.

Depending on the dimensions and mounting options of your window, our T5 integrated linear fixtures may also be worth considering.

The T5 integrated linear fixture sounds great.  The inside dimension of the window is 70 inches wide and 46 inches tall.  Do you think a single 2-ft fixture will be sufficient? 

Based on these dimensions, up to three 2-ft T5 light fixtures could be used to evenly fill the space.

These 2-ft T5 light fixtures can also be daisy-chained together, which means they can all connect to a single power outlet.

Since the window faces the outside, there is some condensation on the window glass. Do you think condensation would be an issue?

Based on the information available to us, it is difficult to say with any certainty whether or not condensation would still be an issue for these fixture mounting solutions.

It may be worth investigating for the presence of moisture on or near your window, in order to have a better idea of the safety hazards which might be present. If, for example, visible water droplets are present, that would certainly be a situation where condensation would indeed be a safety concern.
