How Can We Help?

LED Lights for Recessed and Enclosed Fixtures

I have a few fixtures - recessed and enclosed wall lights that need bulbs. Can someone please call me to discuss the options and pros/cons of your models? 

​While the majority of our products are unfortunately incompatible with fully enclosed fixtures, you may alternatively be interested in our 2700K and 3000K Ultra High 95 CRI A19 5W LED Filament Bulbs. These products are compatible with both enclosed fixtures as well as damp installation areas such as powder rooms. 

What about your BR30? Can I use this in a recessed can? How does the flicker rate of the BR30 compare to your centric models? For the A21, I read it’s not dimmable. If the switch has a dimmer, can I try it in the fixture or not at all? Wasn’t sure if it wouldn’t dim or if would damage the bulb.

While our BR30 lights are available and commonly used for recessed lighting, these lights are unfortunately incompatible with fully enclosed light fixtures. As such, they may not be the right match for your installation. 

So long as the dimming function is not utilized, and so long as the output is set to 100%, we would not expect the A21 bulbs to encounter issues while operating within a fixture containing a dimmer. That being said, please note that activating the dimmer during operation would likely cause damage to the bulbs. 

Do you have 40W flicker-free bulbs?

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

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

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

Does any of the bulbs can be used in an enclosed fixture?

Could you please tell me if any of the bulbs can be used in an enclosed fixture? I’d like to put them in the kitchen ceiling fixtures, however, they are both enclosed. 

We are happy to confirm that our A19 filament bulbs are compatible with fully enclosed fixtures as well as damp locations such as restrooms. For kitchen installations, we would likely recommend the 3000K Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential. 

If you would like to try these lights in your kitchen, please feel free to take advantage of our 30-day return policy. We will gladly provide you with a prepaid return label for any items within domestic orders. 

95 CRI Flicker-free LED Light in 5000K

Is any LED available with both wrlds, no flicker, and 95 CRI or higher and 5000K?

Based on the details provided, we would likely recommend our 5000K CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free A19 10W LED Bulbs. These products have full spectrum output, a high CRI of 95+, and feature flicker-free operation. 

Full Spectrum LED Bulb for SAD Disorder

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

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

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

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

Flicker-free 40 Watts Clear E26 Edison Bulb

Do you have a product that is a clear E26 bulb? Our new lamp requires a clear E26 40-Watt bulb. I was hoping you stock a flicker-free alternative. 

Based on the details provided, it appears that the closest match in our catalog would be our 40W-equivalent Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential, which utilizes a clear bulb enclosure. 

However, this product is unfortunately not flicker-free. We apologize!

Warm Lightbulb Recommendation for Reading Light

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

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

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

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

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

Which of your LED bulbs is to be used in an enclosed lamp in a kitchen area?

I see you can’t use some of these in enclosed lamps, so which can you use in an enclosed lamp in a kitchen area? That would give you enough light. Also which In an enclosed lamp in a hallway? 

For enclosed residential fixtures, we often recommend the 2700K or 3000K options of the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential. 

These lightbulbs offer high CRI full-spectrum output and are suitable for enclosed fixtures and damp installation areas such as powder rooms and restrooms. 

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

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

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

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

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

Do you have a flicker free lower watt (40W or 25W) replacement bulb?

I have been enjoying the 2700K Centric Home flicker-free bulbs for a couple of years now. They are the best. Are there any plans to produce a 40W or 25W replacement that is flicker-free? My house has loads of fans with 3 light sockets. A 450ish lumen 2700-3000K would be a choice!.

While we are aware of any plans to introduce 25W or 40W equivalent for our standard A19 bulbs, you might alternatively be interested in our 40W equivalent 2700K and 3000K Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential. 

These lightbulbs provide the same high CRI of 95+ as our standard A19 lightbulbs, while also outputting a reduced 450 lumens compared to the 800 lumens of the standard lightbulbs. 

In the photometric test report for the 2700K, the flicker index is 0.06. How does that correspond to the output variance by percentage? Would you by chance have any slow motion videos of this bulb?

We can confirm that a 0.06 flicker index denotes a fairly low quantity of flicker. As the flicker index is on a scale from 0.00-1.00, the rate would translate to a 6% flicker percentage. That being said, the difference in output between 0% and 6% is quite visible when capturing slo-mo video on a mobile device. 

Bulb Recommendation for Traditional Track Lighting

I'm thinking a more traditional track lighting setup (ie, aluminum track, individual heads) might be a better solution than the LED strip due to the configuration of the ceiling in the space. Specifically, there is a beam that runs the length of the ceiling (serves as an engine hoist). To properly light the space. I fully anticipate the need for a track on either side of the beam.

Depending on your thoughts, perhaps I should more thoroughly explore your A19 bulb options for a solution. I have just about zero experience with track lighting, so would need to know how many heads, the interval on the track, etc etc. What strikes you as a sensible way to go?

Based on our review, we believe that your installation would be uniformly illuminated by 10 units of our BR30 lightbulbs. 

From what we have found on Home Depot’s website, there appear to be several 8-ft and greater track lengths that can be interlinked to accommodate any number of BR30 track light heads. These heads can be adjusted to any location on the tracks, which we believe should help illuminate specific prints and artwork that are on the walls of the space. 

We believe that utilizing five track lighting heads on each side of the ceiling support beam should provide evenly distributed light across the entire space, though you may find benefit in some fine-tuning. Hopefully, this type of installation allows you to illuminate just the portions of the walls that you would like. 

If you wind up preferring our A19 or A21 bulbs instead of the BR30 lights, please let us know and we will gladly provide you with a prepaid return label so that the unneeded items can be returned to us for a refund. 

I will check out Home Depot for the track pieces and see what I can configure. Just to clarify, the lighting in the two parallel tracks (ie using BR30s) will be used to illuminate the vehicle below only. I will have separate, conventional recessed lighting (two units) to light the wall where I have some artwork. So the entire focus of the track lighting is to properly illuminate the red car. 

The garage floor will be roughly 9' below where the bulb on the track will be. For uniform lighting do you recommend a particular interval on the track for the BR30?

As our BR30 lights have a beam angle of 120 degrees, we typically recommend placing them no further apart than the distance between the lights and the floor or illumination target. 

As the track lighting will be 9’ from the garage floor, we would recommend installing the lights upon the track no further than 9’ from each other. 

Focusing on the BR30s, I think I'm pretty well ready to move on this thing. 

-The ceiling is 9'3" and the range from the bulb to the target will be something less as of course it will be mounted in a head suspended from the track.  

-The distance between the two parallel tracks is 142". This dimension may shrink slightly based on where the darned ceiling joists are. 

-I've spaced the heads (each with a BR30 bulb) at 4' intervals on the track

I want both tracks to be dimmable in tandem, on a single circuit which I'm thinking should be pretty straightforward.

Please wade in with any thoughts on my plan of lighting the space with 10 heads (ie 5 on each track). Also, I would appreciate your insight on Kelvin. Is there a standard? Given the application (ie illuminating a red car) should I be looking at 4000? 5000? Finally, where can I find the R9 values for your BR 30 bulbs?

Based on the details provided, we might recommend the 5000K color temperature option of our Full Spectrum E26 BR30 LED Bulb. 

While 4000K is a common ‘neutral white’ color point for retail and office spaces, the 5000K option can be very beneficial for installations where color accuracy is important.

Which LED Light Color Temperature Should I Choose?

Difference Between 5000K and 6500K Bulbs

Though the 4000K BR30 photometric report is currently available, we do not yet have test data for the 5000K and 6500K BR30 options. 

Does Waveform recommend any one brand of these things over the other? Similarly, what specific dimmer do I want to buy that's most compatible with your Full Spectrum E26 BR30? I see many things out there referring to an R30-shaped bulb....are the BR30 and the R30 the same size?

In the track department, my understanding is I should be looking for the H spec track, which of course will necessitate I have H spec (Halo compatible) heads.  

Unfortunately, we do not have any specific track lighting brands or models that we would recommend, and we do sincerely apologize for any complexity this may add to your purchase planning. 

That being said, we are happy to confirm that our BR30 products are compatible with the dimming technologies used within most products on the market. 

Based on our understanding, the R30 and BR30 lightbulb are largely interchangeable with fixtures as they are the same size. Further, the BR30 has a narrower beam angle due to the more directed reflector within. 

What is the flicker index or percentage of the A19 filament bulb?

I want to ask what the flicker index and/or flicker percentage is for the A19 Filament LED Bulb; and do you know if they would change as you dim the lightbulb? 

We can confirm that the flicker rate is not expected to adjust based on which dimming level the lightbulb has been set to. 

We have provided links to the filament bulb photometric reports below, which display the flicker rate of each color temperature available.

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

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

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

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

Light Recommendation for Office and Residential Lighting

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

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

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

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

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

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

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

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

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

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

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

High CRI E27 flicker-free LED Bulb

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

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

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

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

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

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

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

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

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

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

Why your LED bulbs can not be used in enclosed fixtures?

Can you tell me why your bulbs can not be used in enclosed fixtures? Is it because they generate heat? I am looking for bulbs I can use in enclosed light fixtures. 

We can confirm that many of our lightbulbs require moderate airflow to allow for the dissipation of heat from the internal product components. 

When these products are installed within enclosed fixtures that do not allow for heat dissipation, they will experience a higher failure rate. 

As alternatives, you may also be interested in our filament bulbs, such as the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential, which are designed to be compatible with fully enclosed fixtures. 

I'm unsure if the wattage on your filament bulbs will supply enough light for our current 3 bulb 60 watt indacesant kitchen fixture. Can you provide more information on that.

We can confirm that the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential is equivalent to 40W bulbs and has a light output of 450 lumens. 

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

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

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

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

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

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

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

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

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

Do you have a 60-watt equivalent A19 3000K dimmable bulb?

There seem to be only 40w dimmable A19 bulbs on your website or am I not looking in the right place? I'm looking for 800 lumens. 

While our standard non-filament A19 bulbs are 60W equivalent and offer 800 lumens, we can confirm that they are unfortunately not dimmable. 

Depending on the fixture being utilized, you might alternatively be interested in our 3000K Ultra High 95 CRI E26 BR30 LED Bulb for Home & Residential, which is a 60W equivalent dimmable product. 

Do you have a 40W Equivalent Centric Home 3000K?

I'm really impressed with your product offering, however, I'd really like to see a 40W equivalent Centric Home bulb in 2700K/3000K. It would be perfect for multi-bulb fixtures in bathrooms where 60W equivalent is just too many lumens. Any plans for a 40W?

Based on the details provided, we might recommend the 40-watt equivalent Ultra High 95 CRI A19 5W LED Filament Bulb. 

These lightbulbs are available in both 2700K and 3000K, are suitable for damp locations such as bathrooms.

Does your A19 Bulbs coated with Teflon?

Many shatterproof light bulbs are coated with Teflon (PTFE), which can harm pets such as birds. Can you confirm whether you use potentially harmful coatings on your A19 bulbs? 

We can confirm that our lamps are made of polycarbonate material rather than glass or Teflon. 

As such, there should be no extra coatings on the material or any concerns that might arise from the use of such materials. 

Do you have a dimmable and flicker-free LED bulb?

Are these Ultra High 95 CRI A19 5W LED Filament Bulbs for Home & Residential flicker-Free? If not, do you have dimmable lightbulbs? I have the strips and also non-dimmable and flicker-free, but I have a couple of lamps that are on dimmers. 

Unfortunately, we can confirm that our A19 filament bulbs are not flicker-free. According to the latest photometric report, this product has a flicker percentage of 19.7%. 

We currently do not have any products available which are both dimmable and flicker-free. We apologize!

Choosing Proper Lights for Home Reno Project

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

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

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

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

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

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

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

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

LayoutMaps™ - LED Strip Light Layout 3001-1C

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

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

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

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

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

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

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

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

Are the BR30 bulbs outdoors safe?

I have several waveform lighting bulbs that I am very happy with. I'm about to do some outdoor lighting that is a bit exposed (eg., this cheap home depot fixture) above a grill. Will your BR30 bulbs be ok outdoors? 

Unfortunately, our BR30 LED lights are not suitable for outdoor environments, as they are not IP-Rated. Though our A19 filament bulbs are designed to be suitable for damp locations, they are also intended for indoor use only. 

Recommended LED Bulb for Heavy Night Reading

My daughter is a rising second-year law student, and I'm trying to upgrade the lighting for her desk, in particular. Is a 60-watt equivalent, for a flicker-free light bulb going to be sufficient for the heavy night reading? Should I have 2 lamps of the 60-watt? 

Based on the details provided, we might recommend the 2700K or 3000K color temperature options of the CENTRIC HOME™ Flicker-Free A19 10W LED Bulb. For more information regarding the differences between the two options, we have attached a guide from our website below. We do hope that the resource proves to be helpful. 

Choosing Between 2700K and 3000K

Are Lux24 and Ultra High A19 5W LED Filament Bulb available in E27 base?

Are Lux24 and Ultra High 95 CRI A19 5W LED Filament Bulb available in E27 base? What is the difference between CentricHome 3000K and FilmGrade 3000K? What is the M/P ratio for all CentricHome, FilmGrade, and Ultra High 95 CRI A19 5W LED Filament Bulbs?

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

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

Also, the 3000K CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb and the 3000K FilmGrade™ Flicker-Free A19 LED Bulb are identical products that are provided with unique landing pages for marketing purposes. 

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

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

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

For LED strips, is flicker-free operation determined by the strips themselves or by the power supply? If the power supply is, what should I look out for to go with your LED strips for flicker-free operation?

We can confirm that the flicker-free functionality is a feature defined by the power supply, rather than by the LED strip light products. 

In searching for a third-party power supply that would allow for flicker-free operation, we would recommend comparing the power output against the details within our own power supply specification sheet. So long as the output is compatible, we would assume that the LED strip lights would be able to operate flicker-free. 

FilmGrade™ DC Power Supply for LED Strip Specification Sheet

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

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

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

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

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

Choosing Between 2700K and 3000K

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

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

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

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

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

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

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

Does your A19 Bulb FCC-rated?

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

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

Do you have any dimmable flicker-free bulbs?

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

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

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

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

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

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

I have some questions about A19 bulbs:  

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

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

Difference between CentricHome 3000K and FilmGrade 3000K? 

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

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

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

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

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

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

Flicker Rate of Ultra High 95 CRI A19 5W LED Filament Bulb

I'm wondering if 4002.30.6P has any flicker to it, or is truly flicker-free. I noticed some of your bulbs are specifically mentioned as flicker-free, but not this one. 

We can confirm that the 3000K Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential has a flicker rate of 21.4%.

In case it proves to be helpful with any future purchases, the flicker rates of our products can be found within the photometric reports listed on the product pages. I have attached the report for the 3000K version of the above product below, for your review.

PN4002.30 Photometric Report

Does your A19 5W LED Filament Bulb have low flicker?

I noticed this bulb, unlike the rest, doesn't mention that it is low-flicker: Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential 4002.27 Is this, too, an equally low-flicker bulb?

We can confirm that the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential product is not flicker-free as our other A19 bulbs are, and has a flicker rate of 29%.

For future reference, the flicker rates of our products can be found within the photometric reports on the respective pages. I have attached a link to this product’s photometric report below, for your review.

Ultra-High 95 CRI A19 5W LED Filament Bulb for Home & Residential Photometric Report

If the flicker-free functionality is preferred for the installation, then we would alternatively recommend any of our other A19 LED bulbs such as the CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb​ which is available in the same color temperatures as the filament-style bulb referenced. 

Full-Spectrum LED Bulbs for Residential Lighting

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

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

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

What is the flicker rate of the Lux24 Circadian bulb?

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

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

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

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

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

What is the difference between the A19 LED Bulbs?

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

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

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

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

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

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

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

2400K Photometric Report

2700K Photometric Report

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

Flicker-free Bulbs for Enclosed Fixtures

I'm looking to try some bulbs that will work in enclosed fixtures. I want non-flicker bulbs (I've tried Philips non-flicker bulbs but they flickered like made to my eyes) Can you inform me on which Edison base lights are fixture-friendly (and is there any harm in using one that says 'not suitable for fixtures')? 

The closest product match within our catalog would be the Ultra High 95 CRI A19 5W LED Filament Bulb and the Lux24™ Circadian LED Bulb.

Both of these filament bulbs are designed for use within enclosed fixtures, which means that the hardware within the bulbs is able to withstand the heat that the product generates.

As our other flicker-free A19 bulbs are not designed for enclosed fixtures, they will require additional heat dissipation. 

​

Are your LED bulbs compatible with a boob light?

I'm very interested in your products, but all of the fixtures in my apartment are "boob lights" and my GE bulbs get too hot in them and die horribly. Can I use your lamps in a fully enclosed fixture, or will I have the same problem?

Based on the details provided, we might recommend the Ultra High 95 CRI A19 5W LED Filament Bulbs, or the 2400K Lux24™ Circadian LED Bulbs, as they are designed to be used within enclosed fixtures. 

The other bulb products in our catalog require air flow in order to dissipate the generated heat. As such, we would not recommend these items for the enclosed fixtures mentioned.

Do you have a 2700K flicker-free bulbs for enclosed fixtures?

I'm a happy Waveform customer, but I'm looking for a flicker-free bulb that can be used in an enclosed fixture, preferably 2700k or lower. Do you have any recommendations, or do you know of any products out there that might work? 

Though unfortunately not flicker-free, the closest product matches in our catalog would be the 2700K Ultra High 95 CRI A19 5W LED Filament Bulbs, or the 2400K Lux24™ Circadian LED Bulb. 

Further, we do not have any third-party products we could recommend as an alternative at this time. We apologize!

2700K vs 3000K for “Mancave” with Multiple Light Fixtures & Dimmers

I just repainted the mancave using Sherwin Williams Ceiling White & Pure White walls. I’m installing 2 flush steampunk style ceiling fixtures each with 8 Edison bulbs, and a Dimmer on each. I’m fighting a bluish hue within the room between the changing natural light in addition to both LED & incandescent lights. No websites have addressed the use of Dimmers and their effects when not running at 100%, the preferred watts required per bulb or which color (2700K vs 3000K) to provide the best results.

Based on the details provided, we might recommend the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential in either 2700K or 3000K. Both versions of the product have a 5-watt power consumption and are compatible with dimmers.

If you would like to purchase one of each color temperature in order to make a direct product comparison in your fixtures, please feel free to take advantage of our 30-day return policy.

Compatible Dimmers for A19 5W LED Filament Bulb

I'm interested in specifying your bulbs as you make what I consider the holy grail of LED Edison bulbs and that's one with a CRI of 95! However I need to know what dimmers are compatible with your lamps as I want to ensure there will be no flickering, buzzing, or drop out.

We can confirm that our Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential product is designed for use with modern phase dimmers, though they are not designed for use with older dimmers such as rheostat dimmers.

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

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

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

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

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

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

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

Full Spectrum 4000K Bulbs in 600 Lumens?

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

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

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

2700K LED Bulbs in E26 Base and 120V AC

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

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

CENTRIC HOME™ Full Spectrum Flicker-Free A19 10W LED Bulb: https://store.waveformlighting.com/collections/a19-bulbs/products/centric-home-full-spectrum-flicker-free-a19-10w-led-bulb?variant=16031459344486

Do you have any bulbs with a color temp under 2400K?

Do you have E12 bulbs or consider releasing any? And do you have any bulbs with a color temp under 2400K? I've got an Ikea lamp with an E12 bulb at 2200K and this is excellent lighting for the night. So I was looking for alternatives from Waveform.

Unfortunately, we do not manufacture any lighting products which utilize the E12 standard design at this time.

Further, I can confirm that the lowest color point available among our products is 2400K, which can be found within the Lux24™ Circadian LED Bulb.

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.

Flicker Characteristics of A19 LED Filament Bulb

I am interested in the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential. I would prefer using one of your flicker-free bulbs but they cannot be dimmed. What are the flicker characteristics of this bulb? 

Our A19 filament bulbs have a measured flicker of approximately 20% at 120 Hz. This is in line with incandescent bulbs. (Our photometric reports are here). Unless you have special circumstances that require an even lower level of flicker, we do not believe that the level of flicker exhibited by this bulb would be problematic for most residential applications.

​We completely understand the need for simultaneously achieving dimmability and flicker-free output, and do hope we are able to address this market need in the near future!

Could you suggest any circuit modifications of resistive ballast to prevent flickering from dimming?

I have 6 lights (5W dimmable 2700k A19) on a Lutron CL LED-approved dimmer. I have added 10W of resistive load in parallel to try and prevent flickering from dimming but the lights still have an inconsistent brightness level as they dim up and down. I was wondering if you could suggest any modifications to the circuit to improve the stability. I have also tried it with and without a capacitive load added as well of about 130uF. 

Unfortunately due to variations in dimmer products and configurations, our ability to provide a specific solution in terms of connecting resistive loads here may be quite limited.

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.

Recommended LED bulbs for Sputnik Chandelier Fixture

I have a sputnik chandelier that has 18 lights. The edison bulbs pulled too much energy and overheated the dimmer. I switched to LED but the lumens are so high it's BLINDING even on the lowest setting. These look like a great replacement bulb. What do you think?

Based on the description provided, we believe that the Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential product could be a terrific fit for your sputnik lighting fixture.

However, please know we offer a 30 day return policy. In the event that these bulbs wind up not working well with your installation, simply let us know and we will promptly issue a return label.

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.

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.

Do you have any A19 E26 bulbs suitable for enclosed ceiling light fixtures?

I was wondering if you have any lightbulbs suitable for enclosed ceiling light fixtures for home use -A19 E26. 

I am happy to confirm that we offer A19 filament bulb products, which are able to be used within enclosed lighting fixtures. I have attached links to the products below, for your convenience.

Ultra High 95 CRI A19 5W LED Filament Bulb for Home & Residential:

Lux24™ Circadian LED Bulb - 2400K 95 CRI E26 A19 LED Filament Bulb:

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.

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:

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.

Reason for enclosed fixture ratings

What is the reason your A19 bulbs can not be used in enclosed fixtures? Why am I able to use a 60W incandescent bulb, but not your bulbs which are only rated at 10W?

Our 10W A19 lamps may not be used in an enclosed fixture. The reason is that enclosed fixtures do not provide sufficient free airflow to keep the bulbs cool, and may lead to premature failure.

Although LED bulbs emit less heat than incandescent bulbs, they are much more sensitive to heat due to the internal electronics in the LED bulb. An incandescent bulb is essentially made just of glass and a wire element coil (filament). Therefore, although a 60W incandescent bulb may work fine in an enclosed fixture and emit lots of heat, a 10W LED bulb emitting only a fraction of the heat may still be detrimental to the LED bulb because its components are much more sensitive to heat.

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.
