Replacing an E27 with E26 Fixture
I have just read your great article on "change E26 to E27". I have 3 lamps from Europe with E27 sockets. Are the adapters reliable? Alternatively, is it a fairly easy job for an electrician to change the socket to E27?
Based on our research of the E27 to E26 adapters available locally and through online marketplaces, there appear to be many products available that could be used for your lamps. As we have not personally similarly modified any fixtures, it is difficult to say how reliable the products are.
Having recently spoken to some local electricians regarding lamp base replacement, we have been informed that the process of replacing an E27 base with an E26 base is fairly easy. The most complicated step appears to be finding an E26 base that can neatly fit the lamp socket, given the variation in lamp fixture models. Also, any required wiring adjustments should be fairly straightforward.
Do you offer the T8 LED Tube Lights in a 59-inch (150 cm)?
I am very interested in this product for my Print Studio (D50 5000K T8 LED Tube Lights for Color Matching) but my sockets are 59 inches (150cm) wide. Do you offer this product in this size or only in 48 inches (120cm)? I'm also interested in this Product (NorthLux™ 95 CRI LED Shop Light Fixture) Did this has a clear cover in front of the LED or has it a matte cover so that it does not dazzle strongly and is somewhat softer?
Unfortunately, our T8 LED tube lights are only available in the 48-inch length at this time. For now, we don't have immediate plans to offer additional product sizes. We apologize for any impact this might have on your planning purposes.
However, we're happy to confirm that the newest batch of the NorthLux™ 95 CRI LED Shop Light Fixtures will ship with an installed frosted diffuser cover.
Ceiling Fan Lights Recommendations
I'm trying to find bulbs for a ceiling fan that holds 4 bulbs. I do notice any of my lights that flicker so that's a big deal for me. Any suggestions?
I was thinking about buying a centric home with 95 bulbs but I don't know if I prefer 2700 or 3000. Can't make up my mind today but I'd be glad for some advice.
I do like some smaller shaped lights from Lowes (utilitech) but they don't seem to have them anymore. Do you make any smaller bulbs but still with a medium base?
Based on the details provided, we might recommend the 2700K or 3000K option of the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb product, which is designed to offer flicker-free functionality.
Regarding the selection between 2700K and 3000K, your choice may come down to personal preference. For living rooms and bedrooms, we generally recommend the 2700K option, whereas, for kitchens and dining areas, we would alternatively recommend the 3000K option.
It might also be helpful to know that we offer a 30-day return policy. If the color temperature selection winds up not working well for your space, simply let us know and we would be happy to issue a prepaid return label.
Regarding the bulb sizes currently available, we can confirm that we currently do not have any bulbs smaller than A19 available at this time. However, we are looking into expanding our product line within the near future, and hope to include more standard sizes.
Will 95 CRI BR30 6500K LED bulbs fit any fixtures?
I need help with proper lighting for the new salon. I know I need 6500k 90+cri. I see your artist bulbs are perfect. However, will those bulbs fit any fixtures, if not what kind do they comply with?
We are happy to confirm that our NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio and NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio products are designed to fit within any fixtures that utilize the standard E26 base. For reference, the E26 base is a common standard that you would likely see in the most floor and table lamps.
As such, these products should not require any specialized fixtures for operation.
Compatible Lighting Fixture with T8 LED bulbs for Growing Plants
I want to know what kind of portable fixtures I can use for T8 bulbs for growing plants. I do not want to direct wire them.
We're happy to confirm that our T8 LED tube lights are compatible with many fixtures which do not utilize direct wire installation. However, it might be helpful to know that some fixtures utilize ballasts that may not be compatible with LED lighting.
To select a compatible lighting fixture, we might recommend searching for the term ‘LED Ready’, as that generally denotes compatibility with retrofit T8 style LED lights. Based on my review of third-party storefronts, it appears that there are several available through markets such as Amazon and Home Depot. However, we, unfortunately, do not have any specific models that we can recommend at this time.
The specification sheets for our T8 LED tube lights also include instructions for alternative installation methods, which might prove to be helpful:
https://www.waveformlighting.com/datasheets/CS_4020-4000.pdf
For a list of the ballasts that are compatible with our T8 LED tube lights, please reference this link:

LED Lights in Overhead Soffit to Reflect Off the Ceiling
I generally sit in that recliner at the far end to read. Want to put sufficient light in the overhead soffit to reflect off the ceiling and illuminate the read. The table lamp shown is decorative the task light, barely visible by the chair, is what I use now. Has an LED bulb in it. Glares for the wife seated on the couch. It works well if I bring it down close to the read (magazine or newspaper) bulb is white.
It sounds like we have a few lighting fixtures in your space. To start, are you able to confirm what type of lamps or bulbs your fixtures can accommodate?
For example, the soffit looks like it may accommodate fluorescent fixtures, but it's a bit difficult to tell from the photo.
Similarly, are the table lamp and task light standard fixtures that use medium-screw Edison bases (E26)? (E26 is the most commonly seen, traditional screw-in lamp type with a base that is approximately 1 inch in diameter).
Once you can let us know what types of lamps may be compatible with your existing fixtures, we'll have a better idea of what options we have available for you.
Additionally, can you let us know what challenges you're facing with your existing lighting - is it the color, clarity, brightness, or a combination of these factors?
The soffit has a string of incandescent mini lights, circa 1992. We do not use the table lamp but it and the task light use standard e26 screw-in bulbs, the problem is insufficient illumination. The task light if I bring it close to the reading material will work but is ungainly and if it is set higher is not quite enough light but glares at anyone sitting on the couch. I had thought that linear LEDs in both soffits above the chair reflecting off the ceiling might work but leave that to your expertise. Using dimmers they could also provide illumination for the room. The soffit runs on three sides of the room.
We are in full agreement that improving the brightness from your soffit lighting fixture would be the best approach here to simultaneously increase brightness without causing additional glare issues.
Unfortunately, despite their ubiquity, standard light bulbs induce significant amounts of glare due to their high brightness levels from a relatively small size.
Our first thought here would be to recommend our CENTRIC HOME LED strip lights in 3000K. These LED strip lights emit approximately 450 lumens per foot, which is approximately equal in brightness to a 40-watt incandescent bulb.
It's a bit difficult to determine from your photo, but my best guess would be that your soffit is approximately 10 feet long. If you were to install the LED strip lights across the entire soffit, this would provide you with approximately 4500 lumens, or 400 watts worth of incandescent bulb brightness.
The LED strip lights could of course extend and span multiple soffits across the three sides of the room as you suggest.
The LED strip lights do require some in-wall wiring and assembly work, but I do believe that this would be an excellent option for you. Below is an example wiring diagram that shows how the LED strips can be wired to a wall dimmer:
https://www.waveformlighting.com/layoutmaps/3001_1A
Sometimes sitting on the end of the couch to utilize the halogen Torch which almost does the job but could be better. The new light needs to be dimmable, and maybe the color change?
Each one of the curtains is approx 6 ft across giving us approx 12 ft of the strip light. Approx 5500 lumens per your calculations. You mentioned 3000 Kelvin. Is that overly yellow for reading? Are your strip lights disabled and what dimmer do you suggest for the best performance?
Is there an approved dimmer for 3-circuit control? I note that LeGrand makes a couple although I am partial to Lutron.
I personally do not believe that 3000K is "too yellow" although that would certainly be within the realm of personal preference. Do you know what the color temperature of the lamps in your current space is, and what your thoughts on those might be? (Incandescent bulbs are typically 2700K and lower).
To cover the distances you quoted, you will likely need three sets of 16.4 ft LED strip reels, each with its own dimmable power supply. The cost estimate is as follows:
CENTRIC HOME™ LED Strip Lights for Home & Residential: $99 ea
TRIAC Dimmable Power Supply for LED Strip: $139 ea
We do not have any three-circuit control suggestions, but we do have a list of tested dimmers which are available here:
https://www.waveformlighting.com/files/DC_3093.pdf
The reading lamp has a 790-lumen GE REVEAL built therein. It is I think overly bright white. If I bring it clues to the reading material it works but is glary with poor contrast and if further away not bright enough but not heavy. The soffit has a string of very old very small incandescent. I think we might try one set in the two soffits over the Chair to see how this indirect lighting works.
We believe the GE Reveal lamps use a modified 3000K spectrum. If you find the incandescent lights in the soffit to be acceptable from a color perspective (i.e. not too yellow), then 2700K could also be a good option for you.
Below is an article that might help choose between the two options:

Avian Bulb Placement and Fixtures
Would it be better to use an overhead ceiling fixture in my bird room or something closer to their cage, like a swag? Would a gradual dimming simulate natural sunrise and sunset?
We generally find that widely illuminating a large area using a ceiling fixture is preferable to close-up lighting methods, as this better simulates the effect of natural daylighting across the entire sky.
Gradual dimming would indeed also provide a better simulation of the progression of natural daylight throughout the day, although implementing an automated solution here would be some what challenging.
Does Centric Daylight T8 LED Tube Compatible with PLT Solutions Fixture?
I'm interested in buying these tubes because I can get them in 4000K. I need to buy fixtures though. I want them to be corded with a pull chain. I found these online - PLT Solutions (PLT-11668). Can you tell me if this fixture will be compatible?
Based on our review of the product link provided, we are happy to confirm that the fixture appears to be compatible with our CENTRIC DAYLIGHT™ Full Spectrum T8 LED Tube Lights.
BR30 vs A19 Bulbs for Artist Studio Space Lighting
I want to use the NorthLux 95 CRI E26 A19 LED bulbs in track lighting for a small space of 5 x 6 feet. How many bulbs would you recommend? Can you recommend a source or fixture that would be appropriate for the space?
Based on the details provided, we estimate that your 5x6 space would benefit from roughly 2,389 lumens to be properly illuminated for artwork creation.
As each of the NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio products offers 800 lumens, we estimate that three bulbs could work well for the track lighting in your studio.
While there is not a specific light fixture that we could recommend, it might be helpful to know that our BR30 products are compatible with the standard E26-base track lighting systems that you might find in your local hardware stores.
Are there pros and cons to ordering the NorthLux 95 CRI E26 A19 LED Bulb instead? I see it is not dimmable, and the BR30 bulb is dimmable, but otherwise, I don't understand how they would differ in application. Can I use the E26 fixture with this also?
We're happy to confirm that the A19 bulb is compatible with E26 fixtures and that the performance will be largely the same as the BR30 bulb. The primary benefit offered by the BR30 bulbs is the narrow beam angles, which can be quite useful for track lighting systems with directional lighting.
However, if the NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product winds up not working well in your space, it might be helpful to know that we have a 30-day return policy. Simply reach out to let us know, and we will issue a prepaid return label.
Does the T8 LED Grow Lights compatible with T12 fixtures?
I am looking to purchase the T8 LED Grow Lights for my kitchen. I just wanted to ensure these would be compatible with the current fixture. Currently, my kitchen is lit by 4 Philips f40t12/CW supreme 40-watt bulbs. I believe this to be a T12 bulb. I've heard T8 and T12 are supposed to be interchangeable. However, I was unsure if the ballast capable of powering the current T12s might be too much voltage for these T8 grow lights I'm looking to replace them with. Would the T8 LED grow lights work as a replacement for the Philips f40t12/cw supreme? Ad if not, do you have a suitable grow light replacement for a T12?
The T8 LED lamps will fit mechanically in your current T12 fixture, but the T12 fluorescent ballasts will need to be removed and/or bypassed.
Instructions for how to perform the fixture rewiring can be found in the instructional manual below:
https://www.waveformlighting.com/datasheets/UM_4024.pdf
If you were interested in purchasing a new fixture all together, you may also be interested in our PhotonBlast fixture, which I have provided a link to below:

NorthLux 95 CRI T8 LED Tube for Painting Studio
I'm setting up my painting studio where I create realistic works, and I am looking at using your NorthLux™ 95 CRI T8 LED Tube for Art & Studio. What do I use to hook them up to? Do I purchase one for fluorescents and remove the ballast? A wraparound will look nicer than bulbs, but does it affect the CRI? Also, I have to purchase 4 from you, but I believe 2 will be enough for my space; the room is approx 13' x 15', with a double Easterly window and a single Southerly one.
Our NorthLux T8 LED lamps sound like a great option for your art studio! As you mention correctly, these T8 lamps require a 4-ft fixture housing. Most fixtures that are available today do indeed have fluorescent ballast, so we would recommend removing the ballast and rewiring the fixture to ensure compatibility. Once the ballast is removed, the T8 lamps can be installed directly.
As long as the diffuser cover in the fixture is transparent or semi-transparent (as opposed to having a colored tint), there should be no effect on the light quality and will not pose any problems from a color accuracy perspective.
Finally, I've plugged the dimensions of your space into the lumen estimation calculator which you can find at the link below:
https://www.waveformlighting.com/lumen-calculator
The suggested brightness level to achieve 80 footcandles (recommended for art studios) is 15,722 lumens. Based on this lumen output target, we would recommend up to nine of our T8 lamps. (Your initial estimate for just two lamps may have been based on lower brightness needs in line with a residential space).
Do you have a 4-ft full spectrum bulb suitable for T12 fixtures?
I have two 4-ft spectrum bulbs that are getting old they are fluorescent (TRU LIGHT ULTRA F40T 12TLU). I don't know if I need a fixture or not.
It appears that you currently have a T12 fluorescent lamp in a 4-ft T12 fixture. The good news is that our T8 lamps will fit in your existing fixtures, but the existing fluorescent ballast will need to be removed or bypassed.
Once the ballast removal or bypass is complete, you will be able to use our T8 LED tube lights in the same fixture.
Is any retrofitting required for T8 LED Grow Light Tube installation?
I want to use the PhotonTube™ T8 LED Grow Light Tube in a fluorescent fixture. Is any retrofitting required, or do I merely use this bulb as a replacement without re-wiring/ballast changes?
Our T8 LED tube lights can fit into all fluorescent fixtures that are 4 ft in length. So, if you can confirm that your existing fluorescent fixture is 4 ft in length, we can be quite certain that our T8 LED tube lights will fit!
In terms of the electrical connections, you will want to check if the fluorescent fixture has a ballast inside. If the fluorescent fixture contains a fluorescent ballast, you will want to check that it is listed on our list of fluorescent ballasts, which can be found at the link below:
https://www.waveformlighting.com/datasheets/UM_4024.pdf
If the fluorescent ballast is not listed, you will want to remove or bypass the ballast from the fixture.
Choosing between T8 LED Tube and LED Strips for an Existing Electrical Boxes
I'm trying to choose between tube and strip lights and I need info on how I can hook it into my existing ceiling outlet box.
While each installation can differ, we generally recommend using our LED tube lights if there is an existing 4-ft fixture already in place. Our LED tube lights can be used without a ballast and therefore can be used without any additional electronic components.
LED strip lights, on the other hand, can provide you with some additional versatility and installation options. This approach, however, will require additional wiring and configuration, including power supply units and LED strip assembly.
I have six separate track lights on separate dimmer switches. The reasons they interest me are that they look to be very low profile and you have a 99 CRI strip light but only 95 CRI tube lights. Are there any other advantages or disadvantages I should be aware of for strips vs ubes? If I go with the strip light option, what do I need to do? How does it connect to the end feed and will the extra transformer fit inside the end feed? Will I need new dimmer switches? I currently use these(Lutron CTELV-303P-WH Skylark Contour 300W Electronic Low Voltage Single Pole / 3-Way).
Since you don't have a fluorescent fixture at all, the LED strip light option is definitely worth considering.
The challenge with installing an LED strip light in a location like this is that the existing track systems operate at a completely different voltage type and level. Typically, they are 120 volts or 12 volts AC, while the LED strip lights require 12 volts DC.
As such, the electrical wiring and systems inside the track lights will not be useful here and will need to be bypassed completely.
Below is a configuration diagram for a simple LED strip setup:
https://www.waveformlighting.com/layoutmaps/3001_1A
You will see the TRIAC dimmable power supply, which is the key component here that you will want to determine where you can fit this in your current installation. It is a somewhat bulky device and you will want to ensure it is installed in a location compliant to local electrical code. (Most frequently, it is installed inside of a junction box mounted inside of the wall).
The TRIAC power supply appears to be 9 inches, so it won't fit in the current electrical box in the ceiling. Could I just purchase your junction box and attach it to the ceiling? Do you sell it in white? Alternatively, I could install the TRIAC in the attic near the switches, but then it would need to feed into the current wires that run to the ceiling position. I'm thinking that those standard wires must be different than the ones needed for the DC, is that right? If so, I guess the TRIAC has to go right next to the strip lights.
We are not sure about the electrical code requirements and considerations of mounting the junction box on the ceiling, so that is something you will want to confirm before going down that path. The junction box is unfortunately not available in any other colors.
The concern with installing the TRIAC dimmable power supply far from the LED strip lights is that large distances between the power supply and LED strip lights can result in voltage drop, whereby the brightness of the LED strips become diminished by the reduction in voltage supply. Generally, we recommend keeping the LED strip sections within 32 feet of the power supply unit to reduce the impact of voltage drop.
My understanding is that your tube lights are not dimmable, is that correct?
That is correct. We agree that the LED strips would be the best option for a dimmable + flicker-free lighting solution.
Do you sell L pieces for the aluminum channel so I can turn corners with the flex strips?
Unfortunately we do not sell any "L" shaped corner pieces. The best way to accomplish this would be to solder wires directly between the LED strip segments that meet at the corner. The aluminum channels can also be cut at 45-degree angles to create a gapless 90-degree turn.
Do I need the centric series power supply rather than the triac to get flicker free?
The most recent batch of TRIAC dimmable power supplies is also now rated flicker-free. Therefore, you will be able to use the TRIAC dimmable power supply and achieve flicker-free and dimmable light output.
Do you sell a junction box that covers the centric?
We do not sell a junction box for the CENTRIC SERIES power supply. We would recommend going with the TRIAC dimmable power supply since it also provides flicker-free light output.
Can I connect two separate 8 foot strips to one power supply?
Yes, they can be connected "in parallel" - please see the blog post below:
https://www.waveformlighting.com/home-residential/connecting-led-strips-in-series-vs-parallel
I'm just about ready to order the absolute strip. I'm still trying to decide on whether to go with 6500k or 5000k. What connector will I need for that?
Both the 5000K and 6500K should be good options for you. Here is an article, in case you haven't had a chance to yet see it, that might help you make a more informed decision one way or another:
https://www.waveformlighting.com/art-painting/difference-between-5000k-and-6500k-bulbs
Once the LED strip is cut, it cannot be re-joined using the pre-mounted female DC cables. They can be re-joined using the PN 3071 accessory that you have correctly identified.
Impact of the Enclosed Fixture on Light Output
What happens to the effective spectrum of a bulb if it is used in a lampshade, or in an enclosed fixture with a glass cover?
Most glass covers and lampshades have a minimal effect on the spectrum of light emitted by our products. Generally speaking, the whiter (clear/translucent) the material, the less effect it would have on the spectrum.
Unless the lampshades or covers have a significant color/tint to them, you will most likely not observe any color or spectral shifts.
Does Feiss Issen 2-Light Flush Mount Fixture compatible with your A19 Bulbs? 
I currently have 8 Sylvania 21942 - FO25/741/ECO T8 Fluorescent lights in my L-shaped kitchen and each leg of the L is approximately 12'x7'. Each of these bulbs is 25W, 4100K, and 1755 lumens. I'm switching out the old fixtures and replacing them with 3 Feiss Issen 2-Light Flush Mount FM504SN. It has a closed round glass shade: D: 13.5" H: 1.25" and uses 60W A19 medium incandescent bulbs. I'd like to use LEDs instead, being mindful that the light is closed, not open. Any suggestions?
Based on our review of the Feiss Issen 2-Light Flush Mount product, it appears that while otherwise compatible, the fixture is completely enclosed.
As our A19 bulbs would require a moderate amount of airflow for heat dissipation, these may not be the ideal fixtures for use with our A19 products.
However, we would be more than happy to review any other light fixtures for product compatibility.
Is the BR30 LED Bulb rated for use in recessed fixtures?
Is the “Ultra High 95 CRI BR30 LED Bulb” 4011.30/4011.40 rated for use in recessed fixtures (ceiling cans)?
The BR30 lamps can safely be used in the ceiling can fixtures as long as they are not sealed off. They are unfortunately not rated for enclosed fixture use.
Do your T8 tubes directly go into T12 fixtures as replacements?
Do your T8 tubes directly go into T12 fixtures as replacements? How are the Sidewinder bias strips daisy chained? Are there connectors supplied, and is soldering required?
It sounds like you currently have 4-ft T12 fluorescent lamps. If so, our T8 LED tube lights can be used in the same fixture, as long as the ballast is either bypassed or completely removed. (The new T8 LED tube lights are NOT compatible with T12 fluorescent ballasts, and should be wired directly to line voltage).
For further instructions on installation and wiring, please reference our installation manual:
https://www.waveformlighting.com/datasheets/UM_4024.pdf
As far as the SideWinder product is concerned, located on each end of the LED strip reel is one male DC jack and one female DC jack. As such, no special components or accessories are needed if you are looking to simply daisy-chain the LED strip light reels in an extended run.
Are your LED Bulbs compatible with American Fluorescent Fixtures?
The light fixture I have for this size tube is made by American Fluorescent. Just wondering if this fixture might have proven to be compatible with your light since the list was made.
We're happy to confirm that our Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential products is compatible with enclosed light fixtures. However, our other A19 bulbs will require a moderate amount of airflow and heat dissipation which the enclosed fixture may be unable to provide.
We can also confirm that our T8 LED tube lights are compatible with existing T8 fixtures. However, our T8 LED tube lights may not be compatible with the ballasts within all fixtures. Below is a link that contains the list of compatible ballasts.
Tested ballasts: https://www.waveformlighting.com/files/CD4020.txt
If the ballasts are not compatible, there are alternative installation methods described within the product specification sheet, such as ballast bypass, which could prove to be valuable.
I was more interested in the A19 Bulbs, and I see in your description that they cannot be used in enclosed fixtures (Centric Daylight, NorthLuz, and D50).
Unfortunately, each of the products listed requires some amount of enclosure airflow so that the heat generated by the bulb can dissipate.
Without adequate heat dissipation, the electronic components within the LED products can be prone to error.
Fluorescent Fixture with Independently Controlled Bulbs
I am trying to source a fixture with multiple ballasts or a "smart" circuit to control each bulb in a T8 fixture independently. Ideally, at least 3 bulbs- 2 different wavelength blacklight bulbs and daylight. Do you know if any fixtures allow for individual control of fluorescent tubes?
Unfortunately, we do not have any specific product recommendations which offer the functionality described.
However, if you do find such a product we would be very interested to hear about your experience using it.
Can I plug the realUV LED Strip Lights into a ceiling fan fixture?
If I replace a ceiling fan, can I plug the wires into the old ceiling fan wires and have it work off the light switch?
Thank you for reaching out! Unfortunately our UV LED strip lights are not designed to be mounted into a ceiling fixture and would therefore not be an appropriate installation location.
As an alternative, we would perhaps recommend using our UV flood light, which can be plugged into a switched outlet. Please see below for the product link and let us know if you have any further questions.
https://store.waveformlighting.com/products/realuv-led-flood-lightAre the NorthLux T8 LED Tube Lights compatible with new T8 fixtures?
I will be purchasing new fixtures for the studio I'm renovating. They will be 4' long, with two lamp fixtures each. My question is: Can the NorthLux T8 Tubes be used in newly bought LED wired/ready T8 fixtures instead of using the tubes as a retrofit for existing T8 fluorescent fixtures?
We're happy to confirm that the NorthLux™ 95 CRI T8 LED Tube for Art & Studio product is compatible with new T8 fixtures as well as older retrofitted fluorescent fixtures.
Listed below are three fixtures I'm considering (cost and ease of purchase being the two main deciders). But if there is a recommendation you can make outside of these three fixtures I'm all ears!
Maxlite LSS2XT8USE4803 75303, Nicor 10395EB, Lithonia C 2 32 120 GESB
Using your online lumen calculator, I come up with 19 lamps needed for my 400 sq ft space (ceilings are 8 ' high). So I am looking to do 10 fixtures in this case.
After some review, it appears that each of the lighting fixtures provided is compatible with our NorthLux™ 95 CRI T8 LED Tube for Art & Studio product.
However, it might be helpful to know that the Lithonia and Nicor products utilize ballasts, which can cause some performance issues if the ballasts are not compatible. That being said, there are instructions for installing our tube lights into ballast fixtures using a ballast-bypass method, which is described on the product specification sheet.
Here is a link to our list of compatible ballasts: https://www.waveformlighting.com/files/CD4020.txt
Further, the Maxlite fixture does not appear to utilize a ballast, though the instruction manual for the product does state that it is only compatible with “MaxLite LxxT8SE4xx lamps”. You may want to check with the manufacturer to see if that information is accurate.
Is there a way to cross reference that list with actual fixtures that have those listed ballasts installed in them? When I Googled some of the listed ballasts all I got were web pages for the actual ballasts, not the ballasts as installed in fixtures.
While such a tool would certainly be helpful, unfortunately we do not currently have a way to cross-reference compatible ballasts and light fixtures. We apologize!
What is meant by "enclosed fixture"? And why is this an issue?
You note that the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb is not suitable for use in an enclosure. Can you explain more about what you mean by an "enclosure" and why this is an issue? Is it a heat issue? I have a circular fixture with a 1/4" opening between the top and bottom plates and the center glass piece. Would this be OK?
Some of our products, including the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb, contain electrical hardware within the base of the bulbs which is heat sensitive. As such, these products are known to encounter issues when they have been installed within fixtures that do not allow for moderate airflow.
For instance, a ceiling fixture that is completely enclosed by the glass would not allow for the heat generated by the bulb to dissipate, whereas a wall sconce with an opening would more easily allow for sufficient heat dissipation.
Based on the description provided of the light fixture, you may not encounter heat issues as the fixture appears to allow for moderate airflow.
Can I hardwire the LED Shop Lights to the ceiling?
Would an electrician be able to ‘hardwire’ the Shop Lights to the ceiling replacing the regular ceiling light? I’m trying to figure out how to change the light over my work table without having cords hanging from the ceiling.
The shop lights are unfortunately not designed to be hard-wired and modifying the product is not recommended and would result in voiding the warranty.From a purely electrical standpoint, however, the fixture could be configured to be connected directly to the wiring in your ceiling/walls and would operate without any performance issues. We would recommend consulting with your electrician as well as fire and safety regulators for further guidance.
As an alternative, we would perhaps suggest installing ceiling fixtures that can house our T8 lamps, which can be used to provide the same level of light quality as shop lights.
E26 vs E27 bulbs - Are they interchangeable?
I read your blog entry on the interchangeability of E26 and E27 bulbs (https://www.waveformlighting.com/home-residential/e26-vs-e27-bulbs-are-they-interchangeable) with interest. In the Bottom Line section, you state that "E26 bulbs should not be used in E27 sockets. I live in the US, and recently received a nice lamp as a gift from a UK relative. I can swap out the wall plug relatively easily, but the bulb holder is of a strange design that's difficult to remove/replace. Since I'll only ever be using E26 bulbs here on 120V AC, from an electrical safety perspective, I should be OK, right?
While we cannot guarantee or be liable for any safety concerns, our general understanding of lamp fixture design would suggest that using your E26 lamps in an E27 fixture at 120 volts would be a lower safety concern than doing the same at 240 volts.
Will my existing fixtures work with NorthLux™ 95 CRI T8 LED Tube Lights?
I'm an artist and I need better lights for my studio. I currently have 8 fluorescent bulbs that measure 47" from end to end. The NorthLux sounds perfect but I need to know exactly what I need in order to use them. Will my existing fixtures work or will I have to replace them?
The first thing to check is to ensure that our 4-ft T8 lamps will physically fit in your fixture. If your current lamps measure 47" (hopefully 48" if you include the pins), that sounds like we're definitely in the ballpark!
If you can provide additional photos or model numbers of the current lamps, that should be helpful for us to confirm. A common designation, which would affirm physical fit, would be "F32T8".
We will next want to confirm electrical compatibility. Our T8 lamps can be used in fixtures without rewiring anything, if the fluorescent ballast used in the fixture is listed on our compatible ballast list. The compatible ballast list can be found in the instruction manual below:
https://www.waveformlighting.com/datasheets/UM_4024.pdf
Should the ballast model not be listed on our compatible ballast list, the fixture will need to be rewired to bypass the ballast completely. Additional connectivity diagrams are also shown on the instruction manual posted above.
Below is the photo of what I have. I put these lights up sometime in the early 90s so everything is quite old. I see the code F40T12 which is not what you specified (F32T8) so something tells me I'm going to have to replace everything.
The F40T12 is an older, larger lamp compared to the F32T8, but the length and pin connection are identical, so the good news is that the existing fixture will physically accommodate our T8 LED lamps.
The (slightly) bad news is that the F40T12 fluorescent lamps use a different type of ballast technology that our lamps are not compatible with. This means that the existing fixture will need to be rewired such that the fluorescent ballast is completely removed, or bypassed.
The fixture will need to be rewired according to the diagrams shown in the installation manual, which I have linked to below:
https://www.waveformlighting.com/datasheets/UM_4024.pdf
If you are not familiar with or are uncomfortable with rewiring your fixture, we would recommend working with an electrician to get that complete.
The fixtures I have are really old and were pretty cheap to begin with. Would it make more sense to just take them out and get new ones? If so, could you point me to ones that you would recommend?
From a safety and performance perspective, old fixtures are generally not a problem, unless you are seeing some significant corrosion or other signs of fixture degradation.If, however, for aesthetics or other reasons you are looking to replace the fixtures completely, that can also be an option for sure.It can be a bit tricky to identify new compatible fixtures, however, as many are still sold with fluorescent ballasts inside, and we have no way to guarantee compatibility since fixture manufacturers will often swap out the ballast inside the fixture without advance notice.
We wish we had a list of tested fixtures, but unfortunately we do not have any at this time. A search for "LED ready T8 fixtures" online may yield some results for fixtures which specifically do not have the fluorescent ballast pre-installed. Our lamps should be fully and immediately compatible with fixtures that have this designation.
How about these? LED Ready High Bay
We've reviewed the specs for PLT-20023, and while we have not tested this product, I believe this should work well with our T8 LED lamps.The "single ended direct-wire" and T8 4-ft length specifications are the key specs, both of which are a match with ours.
Fixture Style UV LED Lighting
I have a customer looking for the following: 1st Light UV-A Nanometers: between 315-400nm Fixture Style: Can hang overhead Coverage: A minimum of 3x2 feet for testing purposes 2nd Light UV-B Nanometers: between 280-315nm Fixture Style: Can hang overhead Coverage: A minimum of 3x2 feet for testing purposes 3rd Light UV-C Nanometers: 250nm and below (the lower the better) Fixture Style: Can hang overhead Coverage: A minimum of 3x2 feet for testing purposes.
We are happy to offer the realUV™ LED Strip Light product in both 395nm, as well as 365nm. Each version of this item is available in reels of 3.2 ft (1 meter), and 16.4 ft (5 meter). We also offer the cleanUV™ UV-C LED Strip Light product, which emits 270 nanometer UVC radiation. This product is sold in a 3.2 ft (1 meter) reel.
Further, you may want to consider our realUV flood light available in 365nm and 395nm - a fixture-style that can hang overhead.
Unfortunately, it does not appear that we offer products which meet the '280-315nm' and '250nm and below' requirements requested.
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.
T8 LED Tube Light for Bathroom Installation
Our apartment has weird florescent fixtures in the bathroom. For replacements, we were told to order Sunlite T8 High Performance Medium Bi-Pin (G13) Base Straight Tube Light Bulb, 25W/3500K which is horrible. I am considering ordering CENTRIC DAYLIGHT Full Spectrum Flicker-Free T8 LED Tube Light in 5000K. The fixture is for a 48 inch bulb. Will these work in a bathroom? Also, two of the fixtures are for 24 inch bulbs. Do you have the T8 in 24 inches?
Our CENTRIC DAYLIGHT lamps sound like a nice alternative for what you are looking for.Our lamps are 48" in length and should therefore be a great fit for your bathroom fixture. The lamps are rated for damp location use and there should similarly not be any issues in terms of the installation location.We do offer the lamp in a 4000K color temperature option as well, which may be a more optimal color temperature for a bathroom location for residential installations.
We unfortunately do not have any 24" bulbs at this time. We're sorry for the inconvenience!
LED Light Bulbs Rated for Enclosed Light Fixtures
I am wondering if you sell any light bulbs that are rated for an enclosed light fixture.
We're happy to confirm that our Ultra High 95 CRI A19 5W LED Filament Bulbs and our Lux24™ Circadian LED Bulb - 2400K 95 CRI E26 A19 LED Filament Bulb products are compatible with enclosed light fixtures.
Do you have a Flicker-free Dimmable Bulb Compatible with an Enclosed Fixture?
I live in an apartment with enclosed fixtures and am trying to find High CRI dimmable flicker-free bulbs that will last a semi-reasonable time in an enclosed fixture.
Unfortunately, our dimmable LED bulbs are not compatible with enclosed lighting fixtures due to the requirements for heat dissipation and airflow.
However, if the lighting fixtures are not fully-enclosed, we would be happy to recommend our Full Spectrum E26 BR30 LED Bulbs. These products feature a high CRI and are dimmable. That being said, this product is not flicker-free.
What about the filament bulbs? I know it's not flicker-free (I have some of the BR30s from my old apartment already, but these are def fully enclosed)
Yes. We can confirm that A19 filament bulbs are suitable for use in enclosed fixtures and damp locations.
LED Bulbs for Art Studio with Track Lighting System Compatibility and E26 Base Standard
I'm trying to choose between 2 of your wonderful products to light my art studio. I have 2 rows of track lights with E26 Edison sockets. I'm not sure if I should get the regular bulb (NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio) or the floodlight version (NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio).
We can confirm that both our NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio and NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio bulbs are compatible with track lighting systems that utilize the standard E26 base.
Regarding the differences between the two products, the BR30 does offer a narrower beam angle than the A19 bulb. Other customers have let us know that this feature has been beneficial for their track lighting fixtures.
Recommended Fixture for CENTRIC DAYLIGHT Full Spectrum Flicker-Free T8 LED Tube Lights
I need a fixture that holds four CENTRIC DAYLIGHT Full Spectrum Flicker-Free T8 LED Tube Lights. What do you recommend?
Our CENTRIC DAYLIGHT T8 lamps will fit into virtually all 4-ft fluorescent fixtures. Generally, they will work best without a fluorescent ballast, and as such we would recommend avoiding any fixtures that have fluorescent ballasts already installed. Since it sounds like you are looking for a new fixture to install, you may want to specifically search for four-lamp fixtures without any fluorescent ballasts pre-installed.While we do not have any specific fixture recommendations, we would recommend doing a search for "LED ready" T8 4-ft fixtures, as this will ensure that any new fixture you purchase will not contain any fluorescent ballasts, which can cause additional compatibility issues.
Is this light single or double ended?
The lamps can be used in both single and double ended fixtures.
For your reference, below is the installation guide which shows wiring and additional details for both single and double ended installations:

I am a painter and cannot simply change the bulbs. Do I need to order bulbs and a different fixture, or just buy a full fixture from you?
I am a painter with a small (about 3.5 m by 1.5 m) space where I paint. It's a sunroom and has amazing natural light, but I have been struggling to paint at night. Due to uninteresting reasons, I cannot simply change the bulbs- and I am thus going to replace the entire fixture. Do you think it would make more sense to order bulbs and a different fixture or just buy a full fixture from you?
We may recommend utilizing our bulbs within another replacement lighting fixture, as the current fixtures we offer are not dimmable.
If your replacement fixture accepts BR30 bulbs, we would be happy to recommend using our NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio. We recommend this product because it has dimming capability, offers a high CRI, and emits light that is similar to daylight.
This product has two color temperature options, 5000K and 6500K. 5000K will have a neutral daylight color point, while the 6500K has a color point similar to full daylight. You may find that one option is better suited for your space than the other.
Are E26 Light Bulbs Interchangeable?
I have a fixture that came with a 14 watt E26 standard Medium base CFL bulb. Can I replace these with dimmable LED bulbs?
Based on the description provided, we believe that the following bulbs may work in your fixture, as both are dimmable and have a power consumption under 14 watts.
1. Ultra High 95 CRI E26 A19 5W LED Filament Bulb for Home & Residential
2. Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential
Can I use an E26 BR30 bulb in a recessed ceiling fixture (no covering)?
Can these bulbs be used in a typical recessed ceiling fixture? There is no cover, so the bulbs will not be fully enclosed. I really want to change the lighting and feeling down here in the basement and I'm hoping these full-spectrum lights will help.
We can confirm that the BR30 E26 LED bulbs generally fit into recessed ceiling light fixtures, so long as the fixture is designed to accommodate the E26 base.
Please note that these lights do require airflow for proper heat dissipation. So long as these bulbs are not being covered by an enclosure, they should not experience overheating.
