How Can We Help?

Does A19 LED Bulb for Art & Studio emit UV?

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

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

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

Are your NorthLux A19 bulbs flicker-free?

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

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

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

Difference between NorthLux 5000K & D50 A19 Bulbs

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

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

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

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

​

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

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

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

Ceiling Fan Lights Recommendations

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

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

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

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

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

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

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

Daylight Bulb to View Prints for Color Accuracy

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

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

Suggested Color Temperature for Residential Lighting

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

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

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

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

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

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

Flicker-free LED Bulbs for Golf Sim Room Lighting

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

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

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

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

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

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

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

Household Bulbs for House Plants

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

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

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

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

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

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

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

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

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

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

LED Lighting for Indoor Plants

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

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

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

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

Artist Space Lighting

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

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

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

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

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

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

Lighting Recommendation for Dark Apartment

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

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

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

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

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

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

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

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

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

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

BR30 vs A19 Bulbs for Artist Studio Space Lighting

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

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

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

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

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

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

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

LED Bulbs Products for Color Control in Photography

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

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

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

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

For more information regarding the D50 standard, this article from our website might prove to be useful: 

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

A19 LED Bulbs for Photographing Paintings

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

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

Difference between FilmGrade and Centric Home A19 Bulbs

What is the difference between FilmGrade and Centric Home?

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

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

Oil Painting Studio Lighting Recommendations

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

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

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

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

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

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

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

Flicker-free Bulb for Color Rendition and Artwork

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

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

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

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

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

Are there any flicker-free floodlights?

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

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

Difference between NorthLux and D50 A19 Bulbs

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

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

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

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

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

Centric Daylight A19 LED Bulbs for Bathroom Lighting

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

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

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

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

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

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

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

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

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

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

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

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

LED Light Bulbs Equivalent to Natural Sun/Daylight

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

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

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

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

Difference between Centric Daylight and NorthLux Bulbs?

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

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

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

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

Are your LED Bulbs compatible with American Fluorescent Fixtures?

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

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

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

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

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

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

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

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

Dimmable T8 LED Tube Lights for Art Studio Lighting

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

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

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

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

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

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

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

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

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

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

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

Recommended LED Light for SAD in a Basement Apartment Installation

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

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

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

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

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

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

Choosing LED Northlux vs Centric Daylight for Painting Studio

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

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

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

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

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

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

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

Difference between the NorthLux and D50

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

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

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

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

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

NorthLux vs. D50 for Oil Painting Studio

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

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

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

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

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

Difference in perceived brightness between A19 and BR30 LED Bulbs

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

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

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

FilmGrade A19 LED Bulb 3000K Spectrum Chart

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

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

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

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

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

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

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

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

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

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

Flicker-free LED lights for Golf Simulator System

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

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

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

How many of these installed in track lighting fixtures would be necessary to provide adequate lighting to capture the high speed images? The picture in the Optics attachment on page 10 shows 3 track lighting fixtures with 11 lights distributed among them.

It's a bit difficult to provide a definitive answer for brightness requirements, as this would depend on the camera system and the various light sensors used in the golf simulator.

One way to do a comparison against their recommendation is to compare lamp power. Our LED lamps are 10 watt lamps, so to achieve the same power level as the 8x 15 watt lamp recommendation, you will need at least 12 lamps to reach the same amount of power (8 lamps x 15 watts per lamp = 120 watts).

However, since our lamps are omni-directional, you may not see as much perceived brightness directed towards the golfer, compared to the track light lamps which tend to be more directional. As such, it may be beneficial to increase the power budget further to ensure sufficient brightness.

We would perhaps recommend testing and taking advantage of our free returns policy. If for whatever reason you find that the LED bulbs are not going to work for your project, we would be more than happy to pay for return shipping and offer a full refund. 

Do I want the A19 in 6000K?

Both the 6500K and 5000K should work fine for your needs, as both are calibrated to natural daylight and your camera system should have these calibrations built in. The color temperatures correspond, roughly, to north-facing daylight for 6500K, and direct noon sun for 5000K.​Both options offer 95 CRI and flicker-free light output and therefore should serve well for the application.

High CRI 93 LED Lighting for Residential

I am interested in bulbs with at least a 93 CRI. I see that you sell them. I would like to know what would be the best bulb for my family. The new bulbs sold in stores that are supposedly 60 Watts are not bright enough. What would be recommended and why is that your choice? 

Our 95+ CRI lamps sound like a great fit for you and your family. Our most popular option for residential installations is our CENTRIC HOME A19 lamps, which are available in a 60 watt equivalent brightness. The 2700K and 3000K color options are both excellent options for home use.

Below is the product page for the CENTRIC HOME A19 bulbs:

For more information concerning color temperature, please see our article below:

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

The new bulbs sold in stores that are supposedly 60 Watts are not bright enough. I see you recommended your Centric Home A19 bulbs. Does this seem brighter than the 60 W bulbs I could buy at the store and if so, is that due to the CRI? Why is that your choice to recommend? How many bulbs come in 1 pack?  

The 95 CRI bulbs will most likely provide the same amount of perceived brightness as an 80 CRI bulb that also emits the same amount of brightness (i.e. 60 watts). However, because the CRI is higher, a lower amount of brightness may be sufficient for task-oriented activities, as the improved color clarity may counteract the need for additional brightness.

​We unfortunately do not have any higher brightness bulbs so this would our best recommendation. Generally, we recommend increasing the number of lamps, rather than the brightness of any individual bulb, as this can help reduce glare and improve the light distribution in a space.

The 1-pack refers to 1 bulb.

​We would perhaps recommend testing and taking advantage of our free returns policy. If for whatever reason you find that the LED bulbs are not going to work for your project, we would be more than happy to pay for return shipping and offer a full refund. 

High CRI LED lighting for Photographic Printmaking

I am a professional printmaker for photographers who sell their work in galleries. I also produce prints for museum exhibits and corporate photography installations. I am building a new print-making studio. I would like high CRI lighting for my print viewing/color-correcting area. I need 5000K Hi CRI (95 or higher) for color correcting as well as 2700K and 3000K high CRI to view prints for how they will look under gallery or museum lighting. I would prefer to have one light source to be able to produce all three color temperatures. Each color temperature would be used one at a time. Which of your products would work best for my application?

Our high CRI LED lighting offerings sound like a great fit for both the color viewing (D50 / 5000K) as well as gallery/museum lighting conditions (2700K/3000K).

​Unfortunately, we do not offer any products that feature the ability to switch between those color points, so we would instead recommend installing separate lamps for each of the color points needed.

​For the D50 / 5000K color point, our line of NorthLux or D50 products will work well for your needs. For example, please see below for our A19, T8 lamp or T5 fixture options:

Our 2700K and 3000K are a bit more limited in form factors. Below is our A19 and BR30 lamp option:

If you can let us know a bit more about the lighting installation in terms of fixtures and location, we'd be glad to assist with some additional recommendations and guidance!

Will your T-8 NorthLux 95 CRI LED tubes operate with a dimmable ballast allowing me to dim the output and still maintain the same color temperature and color rendering index?

Unfortunately our T8 LED lamps are not dimmable, and will not work with a dimmable ballast. Sorry for the bad news!

Do BR30 and A19 bulbs dim properly with older-style dimmers that adjust voltage?

Do BR30 and A19 bulbs dim properly with older-style dimmers that adjust voltage? Do the bulbs make a humming noise when dimmed with the older-style dimmers?

We can confirm that our A19 and BR30 lamps are designed for use with modern phase dimmers. However, they are not designed for use with older dimmers such as rheostat dimmers.

As such, these products may not be compatible with the dimmers that you have installed. We might recommend reaching out to a local lighting expert for further specialized instruction regarding compatibility.

LED Lighting Suggestion for Photography

I am looking for an equivalent of 50 W bulb D65 to screw in (for a dim room lighting 8'x13'x8'), another one around 75-80 W D50 also to screw into my desk lamp to hard proof my prints, and another one of around 3700K also for prints evaluation. 

While we, unfortunately, do not offer D65 bulbs that would into traditional lamp fixtures, we do offer the D65 ABSOLUTE SERIES™ LED Linear Module product, which might be an alternative depending on your installation.

We also offer the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) product, as well as the D50 5000K T8 LED Tube Lights for Color Matching (ISO3664:2000) product, which may also be worth consideration. However, these D50 calibrated products are currently only available in the 5000K color temperature.

If I understand correctly, your lights are “full spectrum” eg 6500 K seems to be not far away from D65. Would it be wrong, if my display is on D65, to use one of your bulbs for my ambient light? centric? Northlux? Ultrahigh 95 jewelry? Avian? I do not see any difference between them except that one of them is Flickr-free but same price. 

If this does not work (800 lm could be too bright), and those LED are not dimmable without any further installation, another option could be bias lighting. I have an NEC PA302W: it is a 27.1 x 18 monitor on a stand. Should I use the sidewinder reels? How many? I understand a portion of 24” horizontally, and half of a foot on both sides with 1 reel. Will it be OK like that? Will it be necessary to use a dimmer? I have a black curtain on my window, so it is pretty dark when the door is closed.

We're happy to confirm that the majority of our products are indeed a full spectrum.

Further, we can also confirm many of our products are quite similar. If you have a specific set of products in mind to compare, I would be more than happy to explain the differences between them.

Regarding bias lighting, the Sidewinder™ LED Flex Strip for D65 Bias Lighting product could be a great option for your space.

Based on the measurements provided of your monitor, we recommend two 3.2 ft (1 meter) units of the Sidewinder™ LED Flex Strip product to wrap the back of the display in lighting, depending on the layout that you choose for installation.

This product can also be paired with a dimmer, in the event the level of the emitted light is too bright for all use cases. We recommend pairing this product with the 24V DC power supply, as well as the FilmGrade™ Flicker-Free LED Dimmer product.

I am looking for a D65 bulb for the ceiling but that will be probably too bright as ambient light and this will send some light directly to my computer screen. Moreover, they are non-dimmable or necessitate an installation too complex for me. Anyway, there is a bulb over there, and I will choose one which is adapted; I am a photographer. Flicker-free? 

1. What is the difference between the lights?

Based on the details that have been provided of your space, the A19 bulb that I would primarily recommend would be the 6500K NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product, which was designed to be D65 Illuminant-compliant. This means that the product strictly aligns with a global standard designed for color work. However, please note that while many of our A19 bulbs are flicker-free, none of the A19 bulbs previously mentioned are dimmable. As such, these products may not be beneficial for your space.

That being said, we can confirm that some products are indeed the same item, such as the CENTRIC DAYLIGHT™ A19, as well as the Ultra High 95 CRI A19 bulb. This can be noted by the shared product number, listed as PN 4005.65. This is also true for some other products that we offer. 

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

2. How to connect the 2 strips: daisy chain? connectors?

We're happy to confirm that the Sidewinder™ LED Flex Strip product is designed with plugs on each end of the reel, which allows for the product to be daisy-chained together without additional hardware. I have attached a photo of the product, which may prove to be helpful. That being said, please note that a compatible 24V DC power supply, such as our FilmGrade™ DC Power Supply for LED Strip product, would still be required.

3. What do you mean about “depending on the layout you choose for the installation”?

We do apologize for any confusion caused by my wording. Some bias lighting is installed as one horizontal strip behind the monitor. If this was the installation that you would prefer, we might recommend one unit of the Sidewinder product.

Alternatively, we have seen other bias lighting installed as three strips of lighting. Two vertical strips are applied to the back of the monitor parallel to the sides, and one horizontal strip is applied to the back of the monitor which runs parallel to the top. If this is the installation that you would prefer, we might recommend two units of the Sidewinder product.

Do you have a dimmable A19 LED Bulb?

I don't see any Dimmable LED bulbs on here. Is that on purpose? I'd really like another good option for good dimmable bulbs. CREE bulbs handle dimming very well, but the color is honestly not very good for their standard A19 60w 2700k bulb (even if it says it is CRI 90+). I really loved Hyper ikon's 93 CRI* 3000K bulbs but they supposedly only like ELV dimmers, not PWM. You guys sell a dimmable filament-type bulb which I have not seen before so I'd like to try that in my clear pendant lights instead of the current incandescents. And if those work well, I'd like normal bulbs from you guys but all my lights are on dimmers.

​You are correct that the only dimmable A19 bulb we currently offer is our filament-style lamp. We'll be sure to share your feedback with our product team and do hope we may be able to offer dimmability in our other A19 products in the near future.

Do keep in mind that we offer a 30-day free returns policy, so should you have any concerns or issues with the filament-style A19 lamps, we'll gladly pay for return shipping and provide a full refund.

LED Lighting Suggestion for Small Townhome of 1200 sq ft

Could you suggest a type of LED lighting for a small townhome ~ 1200 sq ft? I have 9 led lights in my downstairs and the room takes a pink/peach hue. I have white walls and want everything crisp, but cannot find a good brand or light.

Our high CRI LED lights should be a great fit for your home.

The first step in determining your lighting needs would be to understand the amount of brightness and the number of lights needed. Based on the square footage provided, we ran some quick calculations using our lumen estimation calculator (https://www.waveformlighting.com/lumen-calculator) which suggests approximately 26,000 lumens as your target brightness level.

​We would further recommend a 3000K color temperature which will provide your residential space with a comfortable but crisp white, light.

Does Full Spectrum Flicker-Free A19 LED Bulb Emit High Levels of EMF?

LED lights are known to emit high levels of EMFs and also produce dirty electricity. Can you tell me more about this regarding these light bulbs? https://store.waveformlighting.com/products/centric-daylight-full-spectrum-flicker-free-a19-10w-led-bulb

We do not have any EMF measurements on our lighting products at this time. We can verify that they are flicker-free, however, with a flicker % of less than 2%.

So you mean to tell me someone can call something "flicker free" even though it still has a flicker?

The official threshold for our flicker-free products is 2%. In actual tests, our flicker % is at 0%. For example, see below:

https://www.waveformlighting.com/photometrics/TR_4005.40.pdf

LED Lights for Textile-Dye Color Matching

I am looking for a lightbulb that will give me the most accurate color reading in my fabric restoration work. I use dyes to restore color loss on carpets and rugs and need to be able to match perfectly the color of the original to the spot I am touching up. What would be the best product for this?

We recommend the D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) product. This product features a high CRI, is flicker-free, and is D50 calibrated for color-critical work which might be valuable for your purposes. We also have a great blog post on our website regarding D50, which I have linked to below in the event that it is useful.

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

​However, please know that offer a 30 day return policy. In the event that one product winds up being preferable over another, simply let us know and we would be happy to issue a free return label for your refund. 

Difference between D50 and Centric Daylight

What is the difference between the D50 and the Centric Daylight?

While both the D50 and CENTRIC DAYLIGHT products offer a 5000K color temperature, the D50 products are calibrated to a specific ISO color point for color viewing applications. For more information, please see below:

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

D50 or 5000K LED Lights with Best CRI for Color Creating and Matching

I'm a colorist, creating foundation shades ( makeup) I was looking for the best light to work with, and I thought the D50 would be perfect I notice Centric Daylight has a better R9 ( 100%) compared to the D50 ( 92%). Also, the Centrix are Flicker free so it would be healthier right? I'm facing north and I have Large Windows Could you tell me which bulb should I get? It would be great on your website to have a Graphic comparing all the light and the data! PS: I wanted to tell you that all the blogs regarding, Kelvin, CRI, UV, and other Questions are so Interesting! 

Based on the details which you have provided, we might recommend the 5000K NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio product, due to the higher R9 value (listed as 94 in our latest photometric report), which could be very valuable for the color work that you mentioned.

However, please know that we also offer a 30 day return policy. In the event that one product winds up being preferable over the other, we will gladly issue a return label for a refund.

Do you have an E27 bulb with D50 and very high CRI 99?

I need a light with very high color reproduction for visual arts applications (slide reproduction = high quality 'scanning' with a DSLR camera). What would be your recommendation?

We would recommend our CENTRIC DAYLIGHT E27 5000K A19 lamp for your needs.

​The 5000K color temperature will meet the D50 chromaticity requirements and the lamp has a color rendering index of 95+.

Comparing the two '5000K Photometric Reports' I can't find any difference between the D50 5000K bulb and the centric daylight full spectrum bulb 5000K you mentioned. Are these two bulbs identic?

We do list our products on multiple product pages, and you are correct that the E27 CENTRIC DAYLIGHT 5000K is the same product as the E27 D50 product. You can confirm this via the part number indicated for both, which are 4007.50.

Is there no bulb version with E27 base 5000K D50 with Absolute Series LEDs CRI 99 available to get a substantial improvement in the reproduction of R12? Is such a bulb with Absolute Series LEDs and higher CRI under development?

Unfortunately, we do not have any lamp products with our ABSOLUTE SERIES LEDs at this time. You are absolutely right that this would allow us to see improvements across the board in terms of color rendering, including R12, and do hope to be able to offer this in the near future!

Will it damage the Centric Home Flicker-Free A19 bulbs using a dimmable power supply?

I bought a few Centric Home A19 bulbs from you. I was looking for a power supply for these bulbs, and I bought a few dimmable ones that can go 5%, 30% & 100% on light intensity. Will that damage my bulbs?

The CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulbs from your order is unfortunately not compatible with dimmer products.

However, we do offer other products which are compatible with dimmers, such as the Full Spectrum E26 BR30 LED Bulbs.

ABSOLUTE SERIES™ LED Flexible Strip for Photographic System for Meat Product Image Analysis

We would like a set of lights with a more accurate representation of daylight, and ABSOLUTE SERIES™ LED Flexible Strip - 99 CRI seems the best option. We would like to mount it in a black box, so we need to standardize lumens in the whole box, without reflections, is it possible to use these LEDS flexing them in a circle of around 60 cm diameter? If not, we should go for the bulbs, in this case, which one of them would you recommend to us? 

Our ABSOLUTE SERIES LED strip lights indeed sound like a great fit, as they will indeed provide you with the most accurate representation of natural daylight.

​The one challenge I foresee with the product is that while it is flexible in an up/down direction, it cannot be made to curve in a left/right direction. As such, creating a circular design with the product would be quite challenging.

​If you can work with a polygonal shape that approximates a circle, such as a polygon with 8 sides or more, you may want to consider using the LED strips in short, straight runs joined together using a connector such as our PN 3071.

For similar lighting quality, we would perhaps suggest our NorthLux A19 lamps, which can be found at the link below:

About the power supply, since we are in Europe, so maybe is better if we buy a European plug, or do you have this option? I understand we need a 120W 12V 10A output. So the female barrel jack and one of the strip-to-strip connection is enough to make the connection, is it right?

You can certainly utilize a European version of the 12-volt power supply. As you mention, the primary requirements are electrical (120 watts, 12V/10A) and to ensure that the output plug is compatible with the ABSOLUTE SERIES LED strip light barrel jack DC connector (included on both ends).​Our North American version can also be used in Spain but will require a plug adapter for the wall outlet ​which you will need to purchase from a third party locally.

As mentioned above, the ABSOLUTE SERIES LED strip light includes the DC connector pre-installed on both ends of the reel. As such, PN 7094 is likely unnecessary.

PN 3071 is the correct accessory to join the cut sections back together at any angle needed.

Are there any known health hazards using red phosphors in the bulbs?

I am outfitting my home with waveform-led bulbs. I was wondering if your bulbs give off UV rays to the occupants. Are there any known health hazards with using red phosphors in the bulbs? I am buying PN 4011.40, PN 4002.30 PN 4011.30 I am hoping that all your lights have reduced blue spectrum and are safer than the typical LEDs at hardware stores. I know that your lights carry the CE rating but are not UL listing. 

Our bulbs do not emit any UV rays, and all emitted electromagnetic waves are longer than 430 nanometers.​There are no known health hazards with red phosphor wavelengths as their peak wavelengths are at 630 nanometers or longer.

These photometric properties apply to all of the PN 4011 and 4002 product lines. For reduced blue light output, we would generally recommend high CRI and low color temperature lamps as they will generally offer the best mix of wavelengths to reduce blue light exposure.

LED Home Office Lighting: Best Color Temperature that Mimic Sunlight

I am trying to mimic "sunlight" in my small home office now that the days are getting shorter. The closest thing to my desired lighting that I have experienced is dental overhead lights. I recently purchased a FilmGrade A19 LED bulb, but it felt a bit cool to me. I realize that natural daylight sits in the 5600K to 6500K color range. 

1) Do you have suggestions for which of your A19 or BR30 bulbs may best fit my use case? 

2) Am I always going to find "natural daylight" options a bit too cool? Would 4000K or 5000K offer a better experience? 

Getting the correct color temperature is indeed a challenge!

​You are correct that the 5000K to 6500K range is generally considered a good match for natural daylight. 4000K is also a nice option, and you may find some useful information on our blog post here.

​One thing to keep in mind that oftentimes, natural daylight color temperatures can appear a bit blue or stark when you do not have enough brightness overall. To that end, if you have any information on the total square footage being illuminated, we may be able to provide some additional recommendations on the quantity of lamps needed to provide sufficient brightness at that color temperature.

We would perhaps recommend taking advantage of our free returns policy to test and compare the various color temperature options and lamp quantities. Once you've made your mind, just let us know and we'd be glad to pay for return shipping and refund you for any returned items. 

6500K Flicker-free Lighting for Art Capture, Color Correction and Fine art Printing

I perform art to capture, color correction, and fine art printing. I am using Ikan Lyra LEDs at this time but not so happy with their results. They are okay, but I am looking for 6500K lighting, also flicker-free. I see you have bulbs and strips. 

We suspect that the primary reason for the difficulty in judging color differences is due to an incomplete spectrum emitted by the Ikan product. Specifically, this will likely be reflected in a low CRI value, possibly in the 80-90 range. (You may also want to look into the R9 value, which provides even more data about red color rendering in particular).

As a starting point, we would recommend experimenting with a few of our 95 CRI products. Here are the A19 bulbs which are daylight calibrated to D50 (5000K) and D65 (6500K) with a 95 CRI rating and would be a great starting point for your tests:

If you would like to consider our LED strip lights, we would recommend our FilmGrade LED strip lights which are offered in both 5600K and 6500K:

Our 5000K LED strip lights (also in 95 CRI) are listed under our retail & commercial section:

Installing the LED strip lights will require a bit of additional assembly and installation work. For additional guidance, we recommend referencing our layout maps which can be found at the link below:

https://www.waveformlighting.com/layoutmaps

​Finally, ​we would recommend taking advantage of our returns policy to test out several of the color temperature options and determine if our products do indeed offer an improvement over your current setup. The full policy can be found below:

https://store.waveformlighting.com/pages/returns-refunds-policy

Do you have BR30 bulbs in 2700K Color Temperature?

Do you not offer the BR30 bulbs in 2700K color temps? The data sheet seems to indicate that you do.

Unfortunately, we no longer offer the BR30 bulbs in the 2700K color temperature.

I am ready to purchase your 3000K flood lights and regular A19 bulbs to retrofit all the existing fixtures in my home. How tightly controlled are your color temperature and CRI values for each of your bulbs, and can I select a particular binning range given that my order will be over $1000?

At Waveform Lighting, we take great care in ensuring the consistency of the products that we offer. This process includes having a very narrow tolerance for variations in the quality of light being emitted by our lighting products.

All of our products are manufactured using single-bin production. Even so, we would be more than happy to provide you with an order containing items originating from the same production batch to be extra sure of color consistency.

Ultra High 95 CRI A19 5W LED vs CENTRIC HOME A19 10W LED Bulb

I need a single bulb that's around 400 lumens and 2700K, so I was looking at your Ultra High 95 CRI A19 5W LED. However, the description does NOT mention that it is flicker-free nor does it mention that it's full-spectrum (while your CENTRIC HOME A19 10W LED Bulb does mention these traits). Is the 5W a lower-quality product? Or is it just fewer lumens?

I can confirm that the 2700K Ultra High 95 CRI A19 5W LED Filament Bulb features the same high CRI of 95+ as the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb. As such, both products are considered to be full-spectrum.

However, the Ultra High 95 CRI A19 bulb does not offer the same flicker-free performance as the CENTRIC HOME™ bulbs. The flicker-rate of the Ultra High 95 CRI A19 bulb is similar to that of traditional incandescent bulbs.

The benefits offered by the Ultra High 95 CRI A19 bulbs can be found in the warmer color temperatures available, as well as the compatibility with dimmers. In contrast, the CENTRIC HOME™ is not dimmable.

LED Lights for Art Painting Studio

We have a studio with existing lighting. This is an artists painting studio so color is paramount and we have never got it right. We would like you to recommend a lighting scheme or bulbs to put in our existing lighting to improve the painting light quality.

Most household lamps have a low color temperature which can be nice and relaxing for a typical residential installation, but for a color-critical application such as yours, having a daylight-calibrated color temperature bulb is definitely crucial.

All of our NorthLux products are daylight-calibrated and will offer a nice approximation of natural daylight, which will help tremendously in being able to accurately see colors in artwork creation.

Since it sounds like you do not have any specific fixtures already in place, you do have quite a bit of flexibility in terms of installation location and types of lamps.

​If you have an table or desk lamps, we would perhaps recommend our NorthLux A19 lamps. Alternatively, if you would like to mount some additional lighting onto a ceiling beam or even a shelf, we would recommend our NorthLux T5 fixtures which may be a great option for you.

Are BR30 Bulbs Compatible with a Legrand Tru-Universal Dimmer?

I have a new job that's interested in your products. I remember the last time, I returned some products because they weren't dimming correctly. Can you confirm that the BR30s are compatible with a Legrand Tru-Universal dimmer and that they don't buzz audibly when dimmed?

We, unfortunately, do not have any test data on that particular dimmer model this time.

In the meantime, if you're in a rush to decide on the installation, we would recommend purchasing a sample set of bulbs to test and see if they work well and provide the lighting performance you are looking for. If it doesn't work out, we'd be glad to pay for return shipping and provide a full refund.

I thought the A19s used to be dimmable. Did that change?

The A19 filament bulbs are dimmable, but the 10-watt A19 bulbs are not. Please see below for the dimmable A19 filament bulbs:

LED Bulbs for Art Studio with Track Lighting System Compatibility and E26 Base Standard

I'm trying to choose between 2 of your wonderful products to light my art studio. I have 2 rows of track lights with E26 Edison sockets. I'm not sure if I should get the regular bulb (NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio) or the floodlight version (NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio). 

We can confirm that both our NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio and NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio bulbs are compatible with track lighting systems that utilize the standard E26 base.

Regarding the differences between the two products, the BR30 does offer a narrower beam angle than the A19 bulb. Other customers have let us know that this feature has been beneficial for their track lighting fixtures.

Lighting for Small Artist Studio Space

I need directions to set up a painting area in the garage. I am looking at the NorthLux lighting CRI 95 or above, around 7000 Lumens and 4,000-6,000K. The area will be around 10 x 8; the ceiling and outside wall is white, and the rest is concrete. The ceiling hight is 7' with 5' deep as my space is under a bulkhead for furnace vents. I want lighting to extend to area approximately 7/8' deep. Could you present me one or two proposed diagrams showing light placement? What is the height of your linear fixture?

Since it sounds like your space currently does not have any existing fixtures, that gives us the maximum flexibility in terms of installation and lamp type options, which is great to hear.

I would recommend our T5 linear fixture at this point, given that it will provide you with all of the necessary housing and mounting accessories without needing to buy any separate components such as a track light tracks and heads for a track light system.

To achieve the 7000 lumen target, you will want one of the following (or a combination of the following):

Unfortunately we're not equipped with any interior design software, so I'm unable to create any layout diagrams showing light placement, but if you have a rough sketch of the space along with some input on where you think the lights can be placed and installed from a practical standpoint, we would be more than happy to offer some additional input.

Generally, you will want to space the lights out as much as possible in order to prevent any excess shadows or hotspots / dark areas. If you will be performing most of your work in one specific area, in addition to the fixtures, you may also want to consider installing a few A19 lamps for localized task lighting:

The height of the T5 linear fixture is approximately 1.4 inches.

Difference between NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio and CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb.

I'm intending to purchase 6500K lighting of either NorthLux™ 95 CRI E26 A19 LED Bulb for Art & Studio (4005.D65) or your CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulb (4005.65). Can you please provide clarification regarding what further differences exist between these two products?

The primary difference between the NorthLux and the Centric Daylight is that the NorthLux has chromaticity points calibrated to D50 and D65 color points, for the 5000K and 6500K versions, respectively.​While the Centric Daylight also offers 95 CRI, the exact color point is not as precise.​If you are looking for a color point that matches ISO standards, we would recommend the NorthLux / D50 product lines.

High CRI 95+ 6500K E26 Color Grading room for editing, coloring matching, and finishing videos and still projects.

I'm looking for a lighting solution for a color grading room for editing, coloring matching, and finishing videos and still projects. In looking through your catalog, there appear to be several matches however they are not specifically listed under the color-matching category. Can you list every product that meets the above specs including non-E26 models?

Currently, the only E26 bulb that explicitly meets the D65 ISO color metric is the NorthLux 6500K A19 bulb. Please see below for the product link:

For non-E26, you may also be interested in our shop light and integrated fixture products, which are shown below:

Lightbulbs mimic the natural lighting in two regions: the Mediterranean and the British Isles.

I'm looking for lightbulbs that mimic the natural lighting in two regions: the Mediterranean and the British Isles.

Unfortunately, we don't have any bulbs that mimic a particular geographic region, but we do offer a CENTRIC DAYLIGHT A19 lamp that will work in standard light bulb sockets. The bulb offers three different color temperatures of 4000K, 5000K, and 6500K which should work well for your needs.

​Please see below and let us know if we can assist with anything else!

The difference between NorthLux and Centric Daylight Lamps in color-accurate lighting application.

What is the actual difference between the NorthLux and Centric Daylight lamps? Is it just that NorthLux has RedBoost and R9 >90 whereas Centric does not, and is only R9 >80, or is there more?

I'm an artist and looking for the most color-accurate lighting option to redo my studio and the entire house. I use 4" T8 tubes in the studio. Would the D50 5000K series render more accurate colors than the NorthLux 5000K? 

I see you have the Absolute Series as well, but it appears to only be available in strips. Do you, or will you have bulbs and tubes available in this series as well? 

The primary difference between the NorthLux and the Centric Daylight is that the NorthLux has chromaticity points calibrated to D50 and D65 color points, for the 5000K and 6500K versions, respectively. While the Centric Daylight also offers 95 CRI, the exact color point is not as precise.​The NorthLux and D50 series are the same product listed on multiple pages. If you are looking for a color point that matches ISO standards, we would recommend the NorthLux / D50 product lines.​Unfortunately we do not have any lamps with the 99 CRI Absolute Series at this time.

Are the NorthLux indeed R9 > 90?

The NorthLux A19 has an R9 value of 90+.

Also, I'm just curious why, if the NorthLux are more finely tuned, are they and the Centric Daylight bulbs the same price? 

We intend to consolidate production for both the CENTRIC DAYLIGHT and NorthLux lamps into a single part number in the future, such that all products would meet the same D50/D65 standard. As such, the pricing was set to the same price point preemptively as we expect to offer the same product in the future.

Are there plans to make any Absolute series bulbs, even just as 4' T8 tubes?

We do have a few plans for future product development in the ABSOLUTE SERIES, but unfortunately, there are no specifics on that yet.

Which of your lighting systems would you recommend for two months old lovebird?

I just got a new baby Lovebird that is about two months old. During the fall and winter, I want to give him adequate light that is as natural as possible so he can be happy and so his body can produce the nutrients it needs. Which of your lighting systems would you recommend? Do you have some kind of kit that would fit inside or above his cage that is simple to set up?

Currently, we are only able to offer individual bulbs for sale and we do not any have kits or complete solutions. If you have any existing lamps or fixtures, our lamps would be a great option to replace any old or burned out lamps, but if you are starting from scratch, you may want to check with some specialty pet supply sellers.

Below are the two lamps we currently offer:

What is the difference between Centric and NorthLux lights, since they each have 5000K and 6500K temperatures?

What is the difference between Centric and NorthLux lights, since they each have 5000K and 6500K temperatures? Do these have the same spectral output and are simply the same lamp but in different product families? For backlighting, 35mm slides when photographing (digitizing) which would be better, a 6500K from the Centric or Northlight groups, or the 5600K Filmgrade since it is supposed to match the camera sensor more closely?

For our A19 lamps, the CENTRIC DAYLIGHT products and NorthLux products both have 95 CRI, but have slightly different color point tolerances, with the latter being more precisely calibrated for color matching and viewing applications.

Specifically, the NorthLux 5000K meets the ISO D50 color viewing standard and may be a preferred option for your camera application. (The products are distinguished by their part numbers, which are PN 4005.50 and PN 4005.D50, respectively).

Regarding color correction, the closest match to D50 with our NorthLux product will suggest that few to no color corrections would be necessary because most camera systems will have the D50 color point likely pre-loaded as their calibration point.

Our FilmGrade A19 is another option that provides the same 95 CRI spectral quality, with a slightly higher blue component compared to 5000K. The 5600K color point is commonly used for photography and cinematography applications and is commonly chosen where ambient lighting conditions are also calibrated to a 5600K color environment.

Given the 95 CRI and high R9 values, the color spectrum of the NorthLux 5000K has sufficient coverage for all wavelengths that the camera sensors are calibrated to.

Are E26 Light Bulbs Interchangeable?

I have a fixture that came with a 14 watt E26 standard Medium base CFL bulb. Can I replace these with dimmable LED bulbs?

Based on the description provided, we believe that the following bulbs may work in your fixture, as both are dimmable and have a power consumption under 14 watts.

1. Ultra High 95 CRI E26 A19 5W LED Filament Bulb for Home & Residential

2. Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential

It shows you have two led bulbs for avian use. However, why the flood light version is dimmable, but the A19 bulb is not dimmable?

Would the A19 bulb blow up or fail if used on a dimmable circuit?At what distance from the birds should these bulbs be used?I always thought birds need UV radiation to produce vitamin D3. Do these bulbs not emit UV rays?

Unfortunately, due to the smaller size of the A19, we have not yet been able to incorporate the electronic components needed to achieve smooth and effective dimming. The A19 lamp cannot be used with any dimmers, even if the dimmer is set to 100% brightness.​We don't recommend placing the lamps too close to birds and maintaining at least a 1-foot distance away. We recommend placing 2-4 lamps per square foot to achieve sufficient coverage.​Our lamps do not contain any UV radiation - if you believe that additional UV exposure would be helpful, we would recommend locating a third-party source for dedicated UV bulbs.

Work light for textiles application used to view texture and detail, neutral to daylight color, and good for indoor use and in a desk lamp.

Can you recommend a work light that will be good for indoor use and in a desk lamp, preferably from neutral to daylight color? I am working with textiles, so not only is color important but being able to view texture and detail.

Is there a bulb you think would work? Or is there a range in color/wattage/bulb type coated or clear that I might have success with?

We would recommend our 5000K or 6500K NorthLux 95 CRI E26 A19 LED Bulb for Art & Studio products could be great options for your desk light, so long as your light fixture can accept A19 bulbs with the E26 base.

The 5000K color temperature would be closer to the 4000K mentioned, while offering a neutral daylight color point. Alternatively, the 6500K color temperature has a light output that is similar to full daylight.

A19 bulbs in semi-enclosed fixtures

The product page for the CENTRIC HOME™ A19 bulbs says they are not suitable for enclosed fixtures. Would they be OK to use in semi-enclosed fixtures? For example, I have some floor lamps with cone-shaped lampshades that surround the bulb. How about desk lamps with similar cone-shaped lampshades?

The 10 watt A19 lamps are not, as you correctly mention, not suitable for use in enclosed fixtures. Our definition of enclosed fixtures is defined as any fixture that completely seals off air flow from the ambient environment. The most commonly seen enclosed fixtures are those in residential ceiling fixtures, where a glass housing completely encloses the fixture base.

On the other hand, table and desk lamps that are partially enclosed will not present any issues with the enclosed fixture rating. Because these fixtures allow for sufficient free air flow, there are no concerns with respect to thermal damage and premature failure.

Best A19 bulbs for digitizing and photographing paintings and artwork?

I am a painter, and am considering using your NorthLux™ A19 bulbs to take photos of my artwork pieces to showcase on my website and other platforms. I am hopeful that these bulbs will reduce the amount of color correction needed post-capture. Are these the best bulbs for my needs?

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

The NorthLux™ A19 lamps are offered in 5000K and 6500K. Although both color temperatures can be considered to be daylight calibrated, 6500K will have a slightly blue hue in line with what you would see from a north-facing window, while 5000K will be more neutral, closer to direct sun. Here is an article going over some additional differences between the two color temperatures. Most camera systems will have a color balance calibration setting that allows for the subtle adjustments that may be needed between these two color points.

Alternatively, our FilmGrade™ 5600K A19 lamps may also be of interest. These lamps are calibrated to 5600K (and 95 CRI, of course), which is a mid-point color temperature between 5000K and 6500K. The 5600K color temperature is calibrated for use in photography, film and TV studios, but can be an equally effective and accurate light source for the purposes of digitizing artwork.

​The A19 / E26 form factor ensures that these lamps will fit in virtually all standard bulb fixtures, so this will give you lots of flexibility and room to try out different positions and orientations to get the optimal set up!

Difference between CENTRIC HOME™ A19 3000K and FilmGrade™ A19 3000K?

Several of our products are listed on multiple product pages for marketing purposes.

Specifically, our CENTRIC HOME™ A19 3000K and FilmGrade™ A19 3000K products are the same product (PN 4005.30) listed on product pages for home / residential applications, and film / photo applications, respectively.

Both products feature the same 95 CRI color accuracy and 3000K color point and are excellent options for both applications.

Do your A19 bulbs emit ultraviolet light?

I'm wondering if any of our A19 bulbs emit any light in the UV range? I'm photosensitive and just want to be really sure they're safe for me. I have been told that wavelengths less than 400 nm are considered harmful.

As can be noted in the product spectrum test report, the spectral distribution trails off before the 400 nm wavelength, so we can be assured that the bulbs do not emit any UV radiation. Below is an annotation of the spectral distribution chart which shows the light output tailing off < 400 nm.

Best bulb for viewing prints and color accuracy?

I am looking for a daylight-calibrated LED bulb that fits into a regular table lamp to view prints. Color accuracy and D50 white balance is crucial. What do you recommend?

Our D50 calibrated, 95 CRI LED lamps sound like a great fit for your needs!

For a basic table lamp with a medium-size (E26) screw base, our D50 5000K A19 LED Bulb for Color Matching (ISO3664:2000) product would be the best fit. This bulb is calibrated to the D50 standard, which would be perfect for print viewing and color accuracy.

10W A19 Lamps Now California Energy Commission Title 20 Compliant

June 7, 2021 - Waveform Lighting is excited to announce availability of our A19 10W LED lamp lineup for California customers. The bulbs listed below are now compliant to the California Energy Commissions Title 20 regulations and can now be shipped to our customers located in the state of California.

The color temperature specifications, along with their updated part numbers are also listed under each product family.

Why are you updating part numbers?

We needed to make some changes to the power electronics inside the bulb to meet the California Energy Commission's requirement for appliances to have a power factor higher than 0.7. The part number designation, printed on the packaging and lamp body, allows us to distinguish our prior lamps with a lower power factor, and those with the updated electronics for a higher power factor. See here for an in-depth explanation.

Is there a difference in the lamps' performance?

From the user's perspective, no difference in the light output, efficiency, brightness, color or flicker will be present. The California Energy Commission's power factor requirement was put in place only to improve the efficiency and reliability of power generation equipment at the power plant, and does not affect the performance of the light bulb itself.

I am not based in California. Does this update affect me?

If you are not based in California, these updates do not affect you. We plan to continue shipping non-CA compliant bulbs from our remaining inventory to our non-CA customers. Both types of bulbs will exhibit the same performance (see prior FAQ) in terms of light output, efficiency, brightness, color and flicker. If there is any confusion regarding part numbers, please see the list above for the mapping of (old -> new) part numbers.

[Archived] What is the difference between CENTRIC DAYLIGHT™ 5000K/6500K and D50/NorthLux™?

[ARCHIVED ARTICLE] This article has been archived as of November 2021 due to recent changes in our product specifications. Please see this article for the most up-to-date information on our current offerings. Customers who purchased our lamps prior to 2021 (lamps marked with PN 4005.XX rather than PN 4005C.XX) can continue to reference the archived information below.

Several of our products are listed on multiple product pages for marketing purposes. One major exception is our 10 watt A19 bulb product line, for which we offer the two part number variants for each of the 5000K and 6500K color points:

5000K:

6500K:

You will notice that the D50 and NorthLux™ product lines have a "D" prefix in the color temperature designation inside the part number. This signifies that these products are calibrated to the D50 and D65 color standards for color viewing and other vision-critical applications at 5000K and 6500K, respectively.

The CENTRIC DAYLIGHT™ products are also available in 5000K and 6500K, but they are not designed for color viewing applications. Specifically, they have a slightly greener tint (elevated Duv values), which is a closer approximation of the ANSI chromaticity targets for daylight color points.

In short, if you're looking for a lighting solution for a professional or color-critical application, we recommend the D50 / D65 designated NorthLux™ lamps. On the other hand, if you're using the lamps for indoor lighting such as light therapy, the CENTRIC DAYLIGHT™ lamps will be a great option.
