How Can We Help?

What's the minimum lumen output of BR30 bulb when using a mains dimmer?

For the BR30 bulbs, when using a mains dimmer like the Lutron Maestro LED+, what's the minimum lumen output from a bulb at the "on the threshold"? Those dimmers have an adjuster to fine-tune the minimum output from the dimmer to feed the bulbs the lowest voltage that will get them to turn on.

For the 5-spec LED strip, when using the Film-grade DMX 50-channel dimmer (3082, 24V), I've noticed that at values <2% (either via manually setting it to 2%, or a value of ~5 via DMX), the LEDs won't turn on (I've been using the 30KHz PWM, but haven't tried lower values). With the LED strips, I'm trying to create cove lighting that can vary from very low levels to very bright. Do you have any recommendations on how to get a lower minimum output from the LEDs?

The minimum dimming level is 20% for the BR30 lamps. Therefore we would expect that the minimum lumen output would be approximately 160 lumens. We have not tested the Lutron Maestro product and are unsure about the dimming trim and whether this would improve the minimum dimming level. You are more than welcome to take advantage of our 30-day free returns policy to test this empirically and determine if this lamp would be suitable for your needs.

​For the PN 3082 DMX decoder, we would recommend adjusting the gamma value. The gamma value will essentially provide you with a steeper or shallower dimming curve, allowing you to adjust the brightness at a rate that better suits your needs (we suspect you will want a value > 1.0). Additionally, we would recommend checking to ensure that your PWM bitrate is set to 16-bit.

Dimmable LED Light for Art Studio

I'm looking for a lamp/bulb for my art desk. I'm am amateur but I appreciate color accuracy using my art markers. Your tube bulbs look appealing but I'd prefer a dimmable lamp. (maybe I can find a lighting fixture that would allow me to only switch on one tube, or both). What do you recommend? 

While we do not have any dimmable light fixtures or dimmable T8 LED Tube Lights, you might alternatively be interested in our NorthLux™ 95 CRI BR30 LED Bulb for Artwork & Studio, which are dimmable and provide a high CRI of 95+. 

Since the Northlux is "dimmable" , could I use it in a simple desk lamp with a dimmer/cord product such as the one below, or would I need a special kind of dimmer control ?

Lutron Credenza Plug-In Dimmer

The Lutron Credenza plug-in dimmer appears to be compatible with our NorthLux BR30 lamp, so that looks like a good choice! (Keep in mind that our NorthLux A19 lamps, on the other hand, are NOT dimmable and cannot be used with a dimmer.)

Can I use a mechanical dimmer switch rated at 600 watts to control all 5 strips?

I need to talk to someone about my project 5- 16 ft runs 0f 3004.40 with 3094.096 triac dimmable power supply. Can I use this mechanical dimmer switch rated at 600 watts? A 24-volt LED flex strip at 14 ft would draw 96 watts x 5 would be well under the 600-watt dimmer rating. 

Based on my review, the 120V Dimmer Switch for LED Light Fixtures within the product link appears to be compatible and able to afford the total 451W power requirements for the five reels of CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail.

LED Dimmer for realUV™ LED Flood Light

What do I need for remote control dimming on the realUV™ LED Flood Light

Unfortunately, the realUV™ LED Flood Lights are not compatible with dimmers, and we do sincerely apologize for any impact that this might have on your purchase or installation planning process. 

For installations where dimming is preferred, we would generally recommend the realUV™ LED Strip Lights as an alternative since they can be paired with the in-line FilmGrade™ Flicker-Free LED Dimmer for adjustment of the ultraviolet output. 

Under Cabinet LED Strip Lights and Accessories

I want to order under cabinet LED strip lighting (3000K) and aluminum channel from you and I want to make certain I order all the correct pieces. 

Here is my setup (all connected via one dimmer switch):

- 19' total lighting

- one 4' section, with power supplied at one end

- one 10' section (3' section, 90° turn, then 7' section, power supplied at one end

- 5' section, power supplied at one end.

- 4 down lights (Dimmable GU5.3 LED Bulb, MR16 70W Equivalent Light Bulb) on same circuit.

Can you put together the correct materials list for me from this description? 

To summarize the conversation, we would recommend the two 16.4 ft (5 meters) reels of the 12V 3000K CENTRIC HOME™ LED Strip Lights for Home & Residential along with two 12V TRIAC Dimmable Power Supplies. 

​This product features insulated wire ends, and should not require an additional adapter for connection to the TRIAC power supply. That being said, segmented lengths that do not have the wired ends can be connected to power using the Solderless Connector Cable for Single Color LED Strip (PN 3070).

Individual segments of the LED Strip Lights can be connected using the Solderless Connector for Single Color LED Strip (PN 3071), which can be especially helpful for corners. We also recommend utilizing 16 AWG Wiring to connect any expanses between the power supply and the lights, in an effort to prevent voltage drop. 

The LED Strip Lights are frequently installed within the flat or corner Aluminum Channel for LED Flex Strips, which help to diffuse the light and protect the light sources from damage. 

Why are you recommending 2 power supplies?

Generally speaking, we recommend utilizing one dedicated power supply per reel of LED Strip Lights, though your 19' installation could very well be powered by a single power supply. 

​As the CENTRIC HOME™ LED Strip Lights for Home & Residential utilize 5.5 watts per foot, an installation using 19 feet would require 104.5W, which is just under the maximum 120W output of our 12V power supplies. If the installation required much more than 19', a single power supply would be insufficient for power, which would likely result in reduced light output across the installation. 

Dimmable and WIFI controllable LED Strip for Outdoor Kitchen Lighting

I am looking for an outdoor kitchen under bar-top strip lighting. I would like multiple color selections and dimmable. I would also like WIFI controllable. Do you have products meeting those requirements?

Unfortunately, we do not have any product solutions that incorporate WiFi control and color changing features. The closest match we can offer is a single-color dimming solution using our LED strip lights.

We have included some installation diagrams below for your reference, most of which show the single-color dimming setup:

https://www.waveformlighting.com/layoutmaps

Wifi/Zigbee Controller Compatibility

I'm interested in lighting my living area with full-spectrum lighting, even supplementing with additional reds and IR to achieve the closest Sunlight as possible. I also want to automate dimming and shutoff so I can kill blue light, at least to an extent after sunset.

I know I can DIY this with a Raspberry Pi and cheap wifi/Zigbee controllers adjusting LED strips, I just want to get your take on compatibility with your high-quality strips. I see y'all don't offer connectivity on your controllers/dimmers so I wanted to ask if it might spell a problem or would just be too hard to do.

While we have not tested our lights with a Raspberry Pi or the Zigbee controller, we have shared a guide below regarding how to connect our LED Strip Lights with a smart home dimming system, which hopefully holds some helpful information for your installation. 

In the hopes that it proves to be useful for your purchase planning process, please note that our LED Strip Lights are not individually addressable. As such, the LEDs will not be able to individually illuminate at the command of a central controller. 

Dimming LED Strip Lights and LED Bulbs using Smart Lighting Systems

Do you have any dimmers that fit well in a standard residential light switch box?

I'm wondering if, you have any dimmers that fit well in a standard residential light switch box.

I found your site based on a search for PWM flicker-free lighting. My main concern is EMF/dirty electricity with no flicker/buzzing on my LED strip dimmer as a side effect/bonus so to speak. Can you speak at all to the relative EMF output of your various options? Do your TRIAC-compatible dimmers use forward phase or reverse? From the little info out there I've been able to research both likely are worse than the PWM. 

If I go with your PWM option is there a way to hardwire to the power supply/strips using regular house wiring as the electrical is done on this project and I can't practically run barrel connectors at this point?

I'm keen on your PWM unit and power supply but would be looking to pair it with this dim-to-warm strip: Ribbon Star Dim to Warm LED Strip Light Would it be compatible?

I have provided answers to each of your questions below, which we hope are helpful for your purchase planning process. 

1.) We, unfortunately, do not sell wall dimmers, and we do apologize for any impact this may have on your purchase planning. That said, we have a list of dimmers that have been tested as compatible with our power supplies. 

2.) We can confirm that our products do not create any dirty electricity as rated by FCC standards for EMF emissions.

3.) Our TRIAC Dimmable Power Supplies are compatible with both forward and reverse phase dimmers and use high-frequency PWM (> 20,000 Hz) for effectively flicker-free dimming. 

4.) We can confirm that our power supplies are designed to be connected directly to line voltage, as our TRIAC and Centric Series power supplies do not use barrel jack adapters. For our LED Strip Lights that utilize barrel jack adapters, we recommend utilizing our adapters for connection to the power supply. 

You say non of your equipment produces EMF. What about when I add a TRIAC switch to your dimmable power supplies, would that potentially add any EMFs to the system?

I ended up purchasing the barrel jack style setup, are there barrel jack to DC adapters commonly available at electronics supply stores?

One more follow-up question. I'm planning an RV build and want the dim to warm strips. 24V 5m iP20 2835 White Dim to Warm LED Strip - 196 LEDs/m (Strip Only) - LED Montreal

Are these compatible with your systems and if so is it possible to run them on 12v?

While the power supply is unlikely to introduce any EMF, the TRIAC dimmer possibly could. 

​As far as we are aware, this would depend on the specific dimmer, installation circuit, and other factors. For specific feedback for your installation, we would likely recommend contacting a local electrician for guidance. 

Further, we can confirm that the barrel jack connectors appear to be fairly common. We suspect that your local hardware store or electronic component specialty store would have those items readily available for purchase. 

As the hardware components within LED Strip Lights are voltage specific, we would not expect the 24V LED Montreal product to be compatible with our 12V power supplies or a 12V system. Using mismatched voltage often causes damage to the components, and will likely void the warranties. That being said, a 12V version would likely be useable if it does not exceed the available power of your vehicle battery or a separate RV power source. 

How many lumens per foot this amber strip light has and also what its equivalent color temperature would be in Kelvin? From what I've been reading there isn't necessarily a direct conversion but would it be about 2200K?

The amber LED strip light has a light output of 185 lumens per foot. Please see below for the full specifications:

https://www.waveformlighting.com/datasheets/CS_7041.pdf

​Unfortunately, there is no way to accurately convert a non-white light source such as this amber LED strip to a color temperature, but 2200K would be a close approximation if one were to "force" a conversion from 592 nm to CCT.

LED Strip for Under-Cabinet Kitchen Lighting

I am looking to install some under-cabinet lights in my kitchen. I listed the specs for my project below and would love your help in figuring out the right lights, power supply, aluminum channel, etc.

-Run length: 90"

-Distance from wall: 11.5"

-Existing cutout in bottom plywood cabinets: cross-section is 0.75" x 0.75" (will the aluminum channel dissipate enough heat?)

-Color temp desired: 3000k

-Dimmable with Lutron Toggler if possible

-Lumens: Whatever is recommended for the kitchen?

Based on the details provided, we would recommend one 16.4 ft (5 meter) reel of the 24V 3000K CENTRIC HOME™ LED Strip Lights for Home & Residential as well as the 24V CENTRIC SERIES™ Flicker-Free Dimmable Power Supply for LED Strip. These products are compatible with a wide variety of Lutron dimmers, as can be noted from our dimmer compatibility list. 

We can confirm that the aluminum channels do a great job of diffusing the heat that LED Strip Lights generates during operation. As your installation does not appear to be anchored to the junction of the cabinets and wall, we would likely recommend the flat version of the channels for even illumination on the counter surfaces beneath them.

If you would like to enter the dimension of your kitchen space in our Lumen Estimation Calculator, it will provide you with an illumination target as well as a recommendation for the total lighting needed to meet that goal. 

High CRI and Dimmable Lighting

Do you offer:

1. slim, can less, LED lighting?

2. LED lighting that maintains a high CRI at dimmer light levels

3. What dimmer is used to achieve the high CRI at lower dimmer settings?

We have provided answers to each of your questions below, which I hope is helpful for your purchase planning process. 

1. We can confirm that we currently do not have any recessed can less ceiling lighting at this time, and we do sincerely apologize for any impact this may have on your purchase planning. 

2. We are happy to confirm that our dimmable LED lighting products will retain their high CRI rating (notated on the respective product specification sheets) when set to any dimming level. 

3. Our LED Strip Light products are compatible with many dimmers, which are featured within our compatibility list. Our standard BR30 bulbs are compatible with wall dimmers as well.

What is the difference between the "CENTRIC SERIES" and "TRIAC" dimmable power supplies?

What is the difference between "flicker-free" and triac dimmers? What do you mean by "flicker free"? Are you somehow varying a DC voltage and current, doing a high rate voltage PWM, or PWMing the current while keeping the voltage constant?

​The only difference between the "CENTRIC SERIES" and "TRIAC" dimmable power supplies is the footprint. The electrical properties for both product lines are the same.

​At full power, the output does not have any PWM in the signal, but when dimmed, the light output is reduced via PWM.

​If you PWM, at what rate?

Our current product iteration utilizes 400 Hz PWM when dimmed. We have completed prototypes and expect to launch a 20 kHz version (when dimmed) within the next few months.

​What is the lowest dim level with the Caseta dimmer? I thought I saw somewhere on your website that it goes down to ~0, somewhere else, the lowest dim level was much higher

Based on our testing with the Lutron Caseta setup, the lowest dim level was 0.2%.

Are your dimmers appropriate at the power levels I need, or are they oversized / drop significantly in efficiency?

​Each power supply has a rated power capacity of 96 watts, so the 22-watt and 35–40 watt LED strip runs will not be an issue. As you mentioned, they can be connected to a single wall dimmer so that the two LED strip runs are "synchronized."

​Is there a way to somehow trim the dimers to make sure that both strips dim consistently; Also, can I set the top dim level down if the strips are somehow too bright for this application?

​Unfortunately, there is no way to adjust the trim on the power supplies themselves, but there are several dimmers on the market that have adjustable trim dials, which may accomplish what you are looking for. If we recall, the Lutron Caseta does not have this feature at the hardware level, but there may be some features inside the software that would allow you to program your preferences.

Do you have data sheets? I did not see them on the website 

​We do not have datasheets published yet, but if you have any further technical questions, we would be more than happy to assist!

Can I use an inline resistor to achieve differential dimming?

I installed three 14-volt LED strips wired in parallel to a dimmable power supply. One strip is about 65 inches long and mounted under our kitchen cabinets for task lighting. The other two 31-inch strips are mounted in the cabinets above that have glass doors. These are strictly decorative, and my wife would like them to be dimmer than the undercabinet light. Can I use an inline resistor to dim the upper two strips?

While we completely understand the idea behind using an inline resistor to achieve the goal of differential dimming, unfortunately, this would not be a practical and recommended approach.

The primary concern is that an inline resistor would need to dissipate a significant amount of heat. If, for example, you have 5 feet of LED strip connected, this would amount to nearly 30 watts (5.5 watts per foot). Reducing the power to the system by just 10% using a resistor would require dissipating 3 watts, which is a significant amount of heat for a small, passive component such as an inline resistor.

There are also concerns with heat buildup and potential safety concerns, especially in a residential installation.

We realize this will increase the total component cost for your project, but the best solution would be to utilize two separate power supplies connected to two separate wall-dimmers.

WiFi Control of FilmGrade Hybrid LED Strip Light

What would you recommend to adjust Kevin Settings & Dimming using WiFi when I pair your FilmGrade Hybrid LED Strip Lighting, coupled with your suggested FilmGrade Power Supply with or without your FilmGrade DMX LED Dimmer & Decoder?

Though we have not performed internal compatibility testing with these types of products as of yet, it appears that this result from Amazon may be able to provide you with the mobile control of the FilmGrade™ HYBRID LED Strip Lights​ that you are hoping for.

This item would likely provide a less complex installation process than the FilmGrade™ DMX LED Dimmer & Decoder with a 5 Channel Output product, which is designed more for the benefit of controlling networked industrial lighting. 

UV LED Strip for Bedroom Lighting

I plan to have 8 feet of 365nm UV strip in each of the 4 corners of the 12 x 11-foot room. Could you advise me on what to order? 

As a primary step, it might be helpful to know that our realUV™ LED Strip Lights have a maximum combined length of 16.4 ft. Connections that are greater than 16.4 ft will result in a voltage drop and reduced output. As such, we typically recommend utilizing one dedicated power supply per full reel of realUV LED Strip Lights. 

It would appear that your installation would require two full reels, as well as two dedicated power supplies. If you would like to use wall dimmers, we would likely recommend the 12V TRIAC Dimmable Power Supply. 

In the hopes that it is useful for your installation planning, we have shared a LayoutMap diagram from our website below. This diagram features links to the connectors and power supplies that are most often recommended for installations similar to the one described. 

LayoutMaps™ - LED Strip Light Layout 7021_4C

That being said, please note that the realUV LED Strip Lights outputs light in the UV-A wavelength range, which is a weaker form of ultraviolet radiation that is found in natural daylight. As such, while there are fewer concerns than with other ultraviolet products that fall under the UV-B or UV-C wavelength ranges, we have some general safety guidelines that we would recommend following:

Do you think that I would be better off ordering 2 flood lights instead?

Generally speaking, while the realUV LED Flood Lights offer a more simple installation that requires fewer connections and power supplies, they are comparatively limited in their ability to be used with wall dimmers. 

​So long as your installation does not require fine-tuning of output or connection to wall dimmers or in-wall power supplies, you may find more benefit in using the realUV LED Flood Lights over the realUV LED Strip Lights. 

What cable lengths come with the FilmGrade LED Dimmer?

I am looking to place the DC power supply and dimmer at a distance from the LED strip. What cable lengths come with the "FilmGrade Flicker-Free LED Dimmer," and can they be extended?

We can confirm that the FilmGrade™ Flicker-Free LED Dimmer utilizes 4-ft (1.2 meters) of 16 AWG wiring on each end. While we do not have longer connection cables available in our catalog, there are likely options readily available from your local hardware or electronic supply store. 

PWM Carrier Frequency for Flicker-Free dimmer

What is the PWM (or PDM) carrier frequency for the FilmGrade™ Flicker-Free LED Dimmer?

We can confirm that the PWM carrier frequency of our FilmGrade™ Flicker-Free LED Dimmer is > 25 kHz. 

LED Strip Light Recommendation for Front Room Installation

I am looking to light my front room with an LED Light strip, preferably 1 power source for my front living room (79 feet total). The room has 10 feet high Barrel ceiling with a piece of trim 8’ up the wall. I wanted to run the strip around the entire room on top of the trim (5/8 inch thick) and use a diffuser strip, maybe V-shaped. There are eight 45-degree angles (the fireplace pops out 1’). Need dimmable, very bright (95+), and perhaps able to change color although the dimmable super bright white is most important. Would prefer to have it wired to a light switch on the wall and a remote to control the colors. Interested in the multicolor or just white?

Based on the details provided, it appears that the installation area would require five 16.4 ft reels of our LED Strip Light products. 

As a starting point, it might be helpful to know that our LED Strip Lights have maximum combined lengths of 16.4 ft for the 12V version, and 32.8 ft for the 24V version. As each foot of LED Strip Lights uses 5.5W, we generally recommend one dedicated power supply per full reel of product. 

For a multi-color installation, we recommend the FilmGrade™ FiveSpect 5-in-1 LED Strip Lights, which can be combined with the DMX Dimmer and Decoder as well as a third-party DMX Controller for the adjustment of each color channel. 

If a single-color white LED Strip Light is preferable, we have many options that can be powered by the TRIAC Dimmable Power Supply and easily connected wall dimmers and smart home systems. For residential installations, we often recommend the 2700K or 3000K options of the CENTRIC HOME™ LED Strip Lights for Home & Residential. 

As can be noted in the LayoutMap below, multiple TRIAC Dimmable Power Supplies can be connected to the same dimmer so long as the maximum amperage is not exceeded. 

LayoutMaps™ - LED Strip Light Layout 3001-1C

We will want the white only dimmable strips. As bright as we can get 24V. Looks like we will need 2 of them and will need 2 power sources. Ran into one dimmable strip. You didn’t mention the V-shaped track with a cover that disperses the light as not to see the individual LED lights. Do you carry those? If not, how wide are the LED strips?

We, unfortunately, do not have any V-shaped tracks, and we do sincerely apologize for any impact this may have on your installation planning. 

Currently, we have both the flat and corner version of the aluminum channels available, which are able to accommodate the 10mm width of our LED Strip Lights. That said, third-party manufacturers such as Klus Design appear to have many other form factor options available. 

Can I use a 9V battery in the input for a LED dimmer?

Can I use a 9V battery in the input? I need an anti-flickering dimmer for my microscope. 

Our LED dimmers are rated for all input voltages ranging from 6 volts to 60 volts, so we would expect that it would be compatible with a 9-volt battery input.

LED dimmer for LED Sign

I need a flicker-free dimmer for an LED sign being used in a video. The FilmGrade dimmer looks like just what I need but I don't know if it will integrate into the existing hardware or if I need to order a new power supply and amplifier as well. The power supply is an HLG-320H-12A. The confusing thing to me is that there is a barrel connector for positive and negative output, rather than one single barrel connector. Max output is 22A, 12V. This feeds into an amplifier. 

At this point, I don't need a remote control. I just need to be able to dim the sign and flicker-free by any means. I would simply buy the FilmGrade dimmer except I don't know if or how it would integrate into the existing setup (do I need to keep the amp? Do I need a smaller power supply to reach the 10A threshold of the FilmGrade dimmer?)

Electrically speaking, our flicker-free LED dimmer sounds like a great option and solution for you. As you've mentioned, however, the concern is with the maximum amperage. We do see that the power supply you currently have is rated at 22 amps. The 22 amp rating refers to the maximum capacity of the power supply, however, and it does ​not mean that the LED system is actually utilizing the full 22 amps.

As such, the next step in determining compatibility is to see what the amperage draw of the LED sign installation is. Typically, the LED sign supplier or the electrician who installed the system should be able to provide this information. Based on this finding, we would be able to further recommend next steps.

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

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

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

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

Do you have a solderless connector that will fit a 0.6" wide LED aluminum channel?

Do you have a solderless connector that will fit inside a 0.6" wide LED aluminum channel? This unit is too wide.

Based on the details provided, we might recommend our LED Strip to Wire Solderless Connector Cable for Single Color LED Strip product, which has a width of 0.54 inches (13.8mm). 

Unless your installation requires the multi-channel FilmGrade™ FiveSpect 5-in-1 LED Strip Lights, the single-color LED connector should be sufficient for your installation. 

​That being said, these dimensions may not allow for sufficient room for installation. If these products do not work well with your installation, let us know and we will gladly provide you with a prepaid return label. 

I do need the 5 wire RGBW version. What do you have for that?

Unfortunately, we do not have alternative solderless connectors for the FilmGrade™ FiveSpect 5-in-1 LED Strip Lights, and we do sincerely apologize for any impact this may have on your purchase and installation planning. 

As an alternative to the connectors, we would likely recommend utilizing soldering so that the products are able to neatly fit within the aluminum channels of your installation. 

Flicker-free Dimmable with a Decor Style Wall Dimmer

Does the below system produces flicker-free output?

FilmGrade™ WHITE LED Strip Lights 

CENTRIC SERIES™ Flicker-Free Dimmable Power Supply 24V

Lutron DVCL-253P-WH = 250W

We can confirm that the 24V 6500K FilmGrade™ WHITE LED Strip Lights (PN3002.65) would offer flicker-free output when paired with the 24V CENTRIC SERIES™ Flicker-Free Dimmable Power Supply for LED Strip (PN3104). 

As a further note, it appears that the referenced Lutron DVCL-253P-WH dimmer would be compatible with the aforementioned products as well. 

Will I be able to dim the lights to a light similar to the tungsten (3200K)?

I am interested in purchasing your FilmGrade™ WHITE LED Strip Lights PN 3001.32, but have a couple of questions regarding them and your dimmer. Your website indicates that they are available in both tungsten (3200K) and daylight (5600K or 6500K). If I also purchase the FilmGrade™ Flicker-Free LED Dimmer PN 3081, will I be able to dim the lights to a light similar to the tungsten (3200K)? Also, we may be moving soon, are the strips easily removed so that we could take them with us?

When the output is adjusted using a dimmer, the lumen output changes while the color temperature does not.

​While traditional incandescent bulbs emit warmer color temperatures while dimmed, LED lighting technology allows for a consistent color temperature regardless of the adjusted dimming level of the output. As such, whether the 3200K product is at 20% dimming or 80% dimming, the color of the output will not change significantly.

We can confirm that the adhesive backing can be removed, though we generally recommend placing them within our aluminum channels for easier future adjustment. 3M sells adhesive remover and replacement tape at hardware stores, as well. 

Recommended Flexible LED Strip Light for Celtic Harp

I need a sticky back flexible light strip to tape to the underside neck of a Celtic Harp. Most strings are whitish, and some are red and blue. Certain stage lighting can cause a vibrating string to become invisible = not good. What K value of light would work best?

Based on the details provided, it sounds as though a low flicker rate of the stage lighting may be causing the vibrating strings to appear invisible, rather than the ‘Kelvin’ color temperature of the lights. As such, we would likely recommend utilizing a flicker-free power supply to pair with our flicker-free LED Strip Lights in your preferred color temperature to solve the issue at hand. 

While we are not familiar with the most common color temperatures of lighting that might be used for cello stage performances, we are happy to confirm that our LED strip lights are available in a broad set of color temperature options. Further, we can confirm that color temperatures are not linked to flicker rates, as each of our color points allows for flicker-free output. 

For powering the cello-attached LED strip lights, we would recommend the FilmGrade™ DC Power Supply for LED Strip. This product can provide flicker-free output and can be connected to wall sockets for power. As many of our LED Strip Lights are available in both 12V and 24V options, we recommend selecting a power supply of a matching voltage. 

Which Strip do you recommend?

-Considering I will be using a 12 V Lithium Battery Pack for boosting batteries (Electrical Instrumentation background)

-I need 3K to 4K light tone and 10 ft flexible sticky back strip

-Since it is against wood (classical harp), do I need to be concerned with heat

Based on the details provided, we would likely recommend our 16.4 ft (5-meter) reel of the 3200K FilmGrade™ WHITE LED Strip Lights. These strips have designated cut points every .984” (25 mm) which can be used to divide them into the preferred lengths. 

As can be noted within the referenced article, we have measured an average temperature rise of 54°F (30°C) over ambient temperatures. If the wood material or finish upon the wood is sensitive to such rises in temperature, we would recommend selecting a third-party light product that has a lower LED density to protect the material. 

While batteries could potentially be used to power the LED Strip Lights, we generally recommend pairing them with a FilmGrade™ DC Power Supply for LED Strip. A dimmer can also be connected in-line to adjust the output. 

LED Strip and Required Accessories for Under-cabinet Task Lighting

I am ordering LED strip lighting PN 3004.40, power supply PN 3092, Flicker Free Dimmer PN 3081, aluminum channel PN 3060, and barrel jack products PN 7095 PN 7094. Are all of these components compatible? To the 2nd question, I am looking for good under-cabinet task lighting in the kitchen. Is the color temperature 4000 a good choice? 

Based on our review of the contents, it appears that all required items are both present and compatible. In the hope that it proves to be helpful for your installation planning, we have attached a LayoutMap link from our website below for an installation using connected LED Strip Lights segments. 

While we typically recommend the 3000K color temperature for kitchens, the 4000K color temperature option can also be a great choice for providing a neutral white color for cooking preparation areas and task lighting. 

If a warmer color winds up being preferable or if any connectors purchased are unneeded, please let us know and we would be happy to provide a prepaid return label. So long as the LED Strip Light has not been cut or altered, we can accept it as a return.

Can I mount the LED dimmer to the underside of the kitchen cabinet?

How do I mount this dimmer to the underside of my kitchen cabinet?

Though the FilmGrade™ Flicker-Free LED Dimmer is not designed for easy under-cabinet mounting, it does seem possible that it could be attached to the underside of a cabinet by using two command strips. 

Using the command strips, which are likely available from your local hardware store, the dimmer could be used to control the light output while also being easily removable for future adjustment. 

As an alternative installation option, it might be helpful to know that under-cabinet lighting is often powered with an in-wall power supply and paired with a wall dimmer for easier control. 

LED Strip for Kitchen Under Cabinets Lighting

I want to light my kitchen under the cabinets. Each cabinet is about 18" wide with a 1-inch box under each. If I cut 3 strips 18 inches long, what would I need to power each? Also, I intend to power them with a wall switch. 

Based on the details provided, we would recommend purchasing one reel of our 3000K CENTRIC HOME™ LED Strip Lights for Home & Residential for your under-cabinet kitchen installation. 

These LED Strip Lights can be segmented, connected with 16 AWG wiring, and powered with the same in-wall TRIAC Dimmable Power Supply for control using a compatible wall dimmer. 

In the hopes that it proves to be helpful, we have attached a LayoutMap below for a similar installation of segmented LED Strip Lights. Within this map, there are links for each of the recommended connections accessories that you may need.

Can I switch between IR (850) and Absolute Series LED Strip?

We would like to be able to use one LED strip and be able to switch between 850 and white light from day to day. Do you have any solution for this?

Unfortunately, we do not have a single product that would be capable of the output range referenced, and we do sincerely apologize for any impact this might have on your purchase planning. 

As an alternative, you might be interested in utilizing an installation that uses a combination of our Infrared 850 nm IR LED Strip Light and ABSOLUTE SERIES™ LED Flexible Strip. This installation could be accomplished by connecting the two products to a shared dimmer or a shared 12V power supply. 

Does your TRIAC Dimmable Power Supply create heat?

I'm planning on creating an installation to bring much-needed light to my living room. (A 16 ft continuous run along 1 wall connected to a dimmer switch on the wall. My question is: Does the Power Supply create heat? That is, could I drop the TRIAC Dimmable Power Supply unit behind the drywall, or would that be a fire hazard? 

We can confirm that the TRIAC Dimmable Power Supply will generate a small amount of heat while operating. We would not expect that this heat would cause a fire hazard. 

Further, when these products are installed behind drywall we typically recommend purchasing the optional junction box to protect the power supply and allow for ease of future adjustment. 

Here’s the circuit I’m planning. Before I order, does that look right to you?

Lutron Wall Dimmer switch 

Power Supply 

LED 24V Strip 16 ft. 

LED Connector Strip 

LED 24V Strip 16 ft.

Based on our review, it appears that the Lutron Diva (PN DVWCL-153PH-WH) is among our list of tested and compatible wall dimmers. As such, we would not expect any issues to arise when using it with our products. 

That being said, we typically do not recommend utilizing DC Power Supplies with in-wall dimmers and connection to in-wall power. As an alternative, we would likely recommend two units of the 24V TRIAC Dimmable Power Supply for LED Strip, as the total voltage requirements of two reels (180.4W) would exceed the available supply from a single unit (96W). 

In the hopes that they prove to be useful for your installation planning, we have attached two LayoutMap links below which illustrate installations that use our power supplies and in-wall dimmers. These pages also feature links to each of the recommended connecter accessories. 

LayoutMaps™ - LED Strip Light Layout 3001-1C

LayoutMaps™ - LED Strip Light Layout 3001-1B

If I wanted to put each LED Strip on its dimmer (16 ft per dimmer, vs 32 ft on 1 dimmer.

Power Supply: Do I need to order another Power Supply? I have already ordered the one you recommended below, but that was for 32’ on 1 dimmer. Do you recommend 2 of the same product or 2 different products?

Switch: What dual dimmer switches do you recommend? I do not see any on the list. 

Based on our review of your recently placed order and diagram, we would recommend utilizing a total of two identical 24V power supplies, with one dedicated to each 16-foot length of the product. 

Though the 24V LED Strip Lights have a maximum combined length of 32.8 feet, each foot requires 5.5 watts of power. As the 24V TRIAC Dimmable Power Supply can offer a maximum of 96W, 24 feet of LED Strip Lights would require a much greater 180.4W of power than could be supplied by a single unit. 

Unfortunately, it does not appear that any of the dimmers within our compatibility list features dual controls, and we do sincerely apologize for any impact this might have on your installation planning. 

Do you have rack mountable DMX-controlled LED dimmer module for dimmable LED lights?

Rack mountable DMX controlled LED dimmer module for dimmable LED lights

Based on the details provided, we would recommend our FilmGrade™ DMX LED Dimmer & Decoder with 5 Channel Output. Though not specifically marketing for rack installation, we have heard of other customers using several daisy-chained units of the DMX Dimmer and Decoder in conjuction for complex lighting installations. 

​That being said, please note that a central third-party DMX controller is recommended for controlling the output of more complex systems. 

Will your LED Strips dim via a wall dimmer with Centric Dimmable Power Supply?

I'm wondering if your film-grade LED strip lights will dim successfully via a wall dimmer if I also use your flicker-free Centric dimmable power supply?

We can confirm that our FilmGrade™ WHITE LED Strip Lights and CENTRIC SERIES™ Flicker-Free Dimmable Power Supply is compatible with the majority of wall dimmer products, as can be noted within the ​dimmer compatibility guide. 

Guidance on Light Type and Required Accessories for Residential Project Lighting

I would like to discuss a project we are working on for a customer and we would like to get some guidance on lighting type and required items to finish the project. 

Requirements:

1) 300 Linear feet of trimless recessed channel in plaster - 3 or 4 inches in size. 2) 80 Linear feet of trimless recessed channel in plaster - 2 inches in size (40 feet will be exterior wall mount).

Item# 1 Some of the area would require 2 LED strip lighting to be run in the same channel. Based on this we would need approximately 600 Linear Feet of LED strip lighting. 

For starters, it might be helpful to know that our LED Strip Light products are sold in 16.4 ft reels, and have maximum combined lengths defined by voltage (16.4 ft for 12V, 32.8 ft for 24V). As such, if any installation where lengths greater than the above is to be connected, they would require dedicated power supplies and connected wiring to the power source. 

If you require longer uninterrupted lengths for your installation, we unfortunately may not have the ideal products available. We do sincerely apologize for any impact this might have on your installation planning. 

​Further, while we currently sell the Aluminum Channels for mounting the LED Strip Light products on walls and other surfaces, we do not have plaster channels available in our catalog. 

I am attaching the plans with this email, we are planning on installing the linear lighting in the OPEN space; only rest of the rooms will have canned LED light. 

1. Family room / Kitchen - various lengths 4, 8 and 12 Foot runs

2. Great Room 4 of 16 Feet Linear light

3. Entertainment - 2 of 3 8 or 12 Feet Linear light

4. Pooja Room - 2 of 12 Feet Linear light

5. Dining Room - 2 of 12 Feet Linear light

6 Walkway Top and Bottom - 4 Feet Runs

Exterior 

Garage Pillars - 3 - 6 or 8 Foot 

Main Door 2 of 8 Feet runs

Though we are more than happy to recommend some products for your construction, we might recommend reaching out to a lighting designer for layout advice, as we do not specialize in planning layouts or lighting installations. 

In the hopes that it proves to be helpful, however, we have attached links to some of our LayoutMaps below, which illustrate installations where segments of LED Strip Lights are powered by multiple power supplies while connected to in-wall dimmers. These pages also list the connection accessories that are recommended, which we hope are helpful for your planning purposes. 

LayoutMaps™ - LED Strip Light Layout 3001-1C

LayoutMaps™ - LED Strip Light Layout 3001-1B

For residential installations, we typically recommend utilizing the 2700K and 3000K color temperatures as can be noted within the guide below. As such, we would recommend the CENTRIC HOME™ LED Strip Lights for Home & Residential product, which is available in those color points in both 12V and 24V versions. 

Which LED Light Color Temperature Should I Choose?

For a list of in-wall dimmers and smart home dimmers that are compatible with our power supplies, such as the TRIAC Dimmable Power Supply, please review the following link. 

Updated Dimmer Compatibility 2021 

Lower Wattage Photon Panel Light

Can you make the 1' by 2' 4000 White Photon panel light in a 50-watt version? Does this panel light come in any other lengths?

Unfortunately, we currently offer the PhotonPanel in a single size and power configuration only.

​While this may not be practical for your particular setup, utilizing a PWM dimmer or a lower-voltage power supply may be viable options for achieving a lower wattage output using the same panel. 

Would we be able to use one dimmer for two panels?

As long as the connected panels do not exceed the power ratings of the dimmer or power supply unit, this would certainly be permissible.

​Specifically, the panels each draw 4.5 amps, so two panels daisy-chained would draw 9.0 amps. The dimmer units have a max amperage rating of 10 amps, so this would be OK, but the power supply would need to have an amperage rating of 9.0 amps or higher to ensure that the total system load is below its capacity (power supply would need be from a third-party, as our power supplies have a max capacity of 5.0 amps).

Do note that the DC input jacks do not allow for daisy-chain input (since the DC jacks are only rated up to 5.0 amps), so the power input (and the dimmer circuit) must be fed through the WAGO terminal blocks. 

Is it possible to dim the realUV LED Strip Light?

LED Strip to Strip PN3071 - Is it possible to dim this LED Strip? Is it possible to operate two 12V strips in a series connection on 24V?

As our LED Strip Lights are designed to be voltage specific, we do not recommend utilizing 12V products with a 24V power supply as electrical hazards may arise which will void the product warranty. That being said, We can confirm that the LED Strip Lights when connected to a matching voltage power supply and dimmer can have adjustable output. 

The dimming of UV-LEDs is possible (PN7021)?

We are happy to confirm that the realUV™ LED Strip Lights can be dimmed using several different products, such as the FilmGrade™ Flicker-Free LED Dimmer and in-wall dimmers which are connected to the 12V TRIAC Dimmable Power Supply. 

Will flickering be eliminated if we follow the dimming guidelines?

If we follow these guidelines, will flickering be eliminated? It doesn't specifically say so in the article. 

Generally speaking, the ability to provide flicker-free output is determined by both the power supply and LED products. As such, the inclusion of the TRIAC Dimmable Power Supply for LED Strip or FilmGrade™ DC Power Supply for LED Strip of a matching voltage should allow for the flicker-free output of the connected LED Strip Lights. 

Lighting Recommendation for Painting Studio

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

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

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

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

Are any or all of these lights dimmable?

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

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

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

LayoutMaps™ - LED Strip Light Layout 3001-1A

LayoutMaps™ - LED Strip Light Layout 3001-1B

LayoutMaps™ - LED Strip Light Layout 3002_2B

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

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

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

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

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

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

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

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

Can I use a Lutron Caseta Switch with your transformer driver and third-party LED Strip?

I had an issue finding a wall switch. Finally found this one and want to use it with your hard-wired or maybe I can use barrel jacks.

Wave Form - FilmGrade™ DC Power Supply for LED Strip

YUJILEDS® High CRI 95+ IP67 Waterproof LED Flexible Strip - 24V

For installations using in-wall power, we recommend using the 24V TRIAC Dimmable Power Supply for LED Strip instead of the FilmGrade™ DC Power Supply for LED Strip. This power supply is compatible with most models of wall dimmers, which include the Lutron Caseta Wireless In-Wall Dimmer featured in the photo that you provided. 

Please note that as this 24V product has a maximum output of 96 watts, it would not be able to provide sufficient power for a product that requires 150W. If the YujiLEDs product requires 150 watts of power, we recommend using a third-party power supply capable of providing that output. For reference, we do not have any power supplies capable of providing 150 watts. 

Flicker-free and Dimmable Lighting Option

My cabinet makers installed Hafele 12 V LED lights on the bookcase. And I make a lot of YouTube videos. Unfortunately, my LEDs flicker and produce annoying lines. The LED strips are RGB and the remote has a dimmer. What can I buy from you to remove the flicker, and allow me to dim the lights? 

As flicker-free functionality is often provided to the connected LED products as a feature of the power supply, we would likely recommend our FilmGrade™ DC Power Supply for LED Strip or TRIAC Dimmable Power Supply for LED Strip for your installation. For dimming your lights, you may be interested in our FilmGrade™ Flicker-Free LED Dimmer. 

Hopefully, these options will allow for your RGB lights to output consistent flicker-free operation. We also recommend ensuring that the lights currently being used are compatible by voltage (12V vs 24V) and draw prior to replacing the currently utilized power supplies. 

Do I need to change out the LED strips? Assuming I replace the LED strips with yours, do you have corner pieces I can use to connect strips in 90-degree connections to turn the inside bookcase corners? What equipment will I need to control the color and saturation of the LEDs? Do I need more Power supplies? (60 feet of lights). Which LED lights do you recommend I purchase?

It appears that the Hafele 833.95.746 driver is able to output either 90W at 12V. At 90W, it appears that they would be able to provide ample power for one full 16.4 ft reel of our LED Strip Lights per power supply. As such, you may be able to replace the lights in your installation with our 12V LED Strip Light products without requiring the purchase of additional power supplies.

For your retrofitting, it might be helpful to know that our 12V LED Strip Lights have a maximum combined length of 16.4 ft (5 meters). As lengths that are greater than this will encounter increasing voltage drops, we would recommend pairing one dedicated power supply per reel. 

For an alternative to the multi-channel Hafele light strip products, we would recommend our 12V FilmGrade™ FiveSpect 5-in-1 LED Strip Lights, which can be paired with our DMX Dimmer and Decoder or third-party DMX controller for the adjustment of light output. 

The controller currently being used by Hafele may also be compatible, though we have not performed any internal compatibility tests with their controllers. If so, this would allow you to continue using Bluetooth control for the installation. 

While do not have corner connectors, you may alternatively be interested in utilizing our 5-Channel LED Strip to Strip Solderless Connectors for the corners of your installation. 

LED Strip Lights for Above-Cabinet Lighting

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

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

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

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

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

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

LayoutMaps™ - LED Strip Light Layout 3002_2D

LayoutMaps™ - LED Strip Light Layout 3002_2B

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

Under Shelf Lighting for Backdrop Studio

I recently purchased some LED strip lights from a third party for under my shelves for the backdrop of my studio for filming cake decorating. We installed all of them, they looked great until we turned on the camera. No matter what shutter speed we chose, there is terrible "banding" from the lights. 

I'm wondering if I could use the current setup I have but use your "FilmGrade™ DC Power Supply for LED Strip" with this setup I already have. It is a remote control setup, so would I need to purchase your dimmer also to make this work? This is what I purchased.

If I wasn't able to use my current setup, what is the full setup I would need to do non-flickering lights under two shelves (43" each) with 27" between them where they'd need an extension? It's really just ambiance lighting, so we're trying to keep it in a friendly-er budget. 

We can confirm that the flicker rate of LED lights is most often defined by the power supply and dimmer utilized, rather than by the LED product itself. 

As such, you may find that utilizing our 12V FilmGrade™ DC Power Supply for LED Strip may improve the performance of your third-party lighting installation. 

​That said, it appears that the remote receiver of the product referenced utilizes a special connection plug which our LED Strip Lights do not use. As such, you may not be able to use our products with the remote and receiver.

Regarding an installation that would use our own products, our LayoutMap pages, such as the ones below, illustrate the arrangement of our components. We estimate that two 43” shelves could be illuminated with one segmented 16.4 ft (5 meters) reel of LED Strip Lights, powered by one dedicated 12V power supply.

Dimmable Power Supplies and Dimmers for Adjustable Backlit Lightbox

I am trying to build an adjustable backlit lightbox for looking at backlit prints at various color temps and brightnesses. Could you provide any assistance with the dimmable power supplies and dimmers? Specs, where to get them, etc.

Based on the details provided, it does appear that our Hybrid LEDs would be a good match for the installation if connected to the shared power supplies in parallel, due to the maximum combined length (32.8 ft) and reduction of required dimmers per channel. 

Regarding the connected power supplies, we would recommend ensuring that they can offer sufficient amperage for the total connected amount of product. For additional connection advice, we have attached a configuration guide for the Hybrid LED Strip Lights below. 

How to Connect Hybrid CCT Tunable LED Products

As an alternative, you may also be interested in our FilmGrade™ HYBRID LED Flex Panel. 

This flex panel product offers the benefit of utilizing 1152 total LED diodes per panel (576 per channel) as well as pre-applied wiring for power, which can help reduce the complexity of larger installations. 

Do I need two power supplies for two (16.4 ft) LED Strips?

I’m interested in the Centric Daylight 4K LED strip lights for my garage. I have a few questions before I place an order. I’m wanting to install two reels worth of lighting (16.4/reel) in my garage. Is the two power supplies I need 3094.096? I’m wanting to use a typical dimmer, for those types of power supplies. Is there an illuminated switch you recommend? I want to be able to see it in total darkness. Also, I want a recessed aluminum channel but I didn’t see them on your website, any brand you recommend or point me where to get them?

You are correct that you will want two PN 3094.096 power supplies for each of the two LED strip reels. The good news is that both of these power supplies can be connected to a single wall-dimmer circuit (in parallel) so that you can control both LED strip reels from a single wall-dimmer. Below is a layout diagram showing how this can be configured:

https://www.waveformlighting.com/layoutmaps/3001_1C

​Regarding illuminated switches, unfortunately, we don't have any active catalog of compatible dimmers with this feature, but we do maintain a general list of tested dimmers which can be found below:

https://www.waveformlighting.com/datasheets/CD_3093.pdf

We should note that our dimmable power supply is designed to work with all phase dimmers, so there is a good chance that it would be compatible with any given illuminated dimmer switch you end up going with (we would still recommend testing before permanent installation).

Our aluminum channel products are not specifically designed for recessed installations, but can certainly be installed in such locations if needed. The product link is below:

For a wider selection of aluminum channels, we would recommend reaching out to KLUS, which specializes in this area. The link is below:

Do you offer a sample kit with DC power and a LED strip?

I have a small photo studio 1m 3. I would like to buy your photography LED strip. The sample kit looks good, but I fear 6" may be a little too small. However, a 5m strip would be vastly more than I need. Would you be able to offer a kit with DC power and a LED strip of maybe 1m? I am in Scotland and so do not want to buy excess as it will add to the shipping and import duties. I look forward to your suggestion. 

While we completely understand the concern, unfortunately, all of our LED strip light products are pre-packaged in 5-meter reels, and we are not able to handle custom or partial reel measurements at this time.

​This may not be helpful from a cost reduction perspective, but we do offer a user-friendly flicker-free LED dimmer which may help allow you to achieve a wide range of brightness settings for your studio space. Utilizing the entire 5-meter reel will not only allow you to achieve very high brightness if needed but also provide a much more evenly distributed lighting effect by allowing the light to emanate from a larger area.

​In case you're interested, I've linked to the product below:

Do you have a suggested Lutron Caseta Smart Dimmer for the TRIAC power supply?

I purchased the Triac Dimmable LED power supply the other day. I'm trying to figure out which Lutron Caseta Smart Dimmer switch I am supposed to use. Lutron support said I should use "Caseta PD-5NE". Please advise if that is the dimmer switch I should be using or if you have any other suggestions. 

We can confirm that our TRIAC Dimmable Power Supplies have been verified as compatible with most Lutron dimmers. This includes ELV (extra-low voltage) dimmers such as the referenced Caseta PD-5NE. 

Further, we expect a wide range of dimmer compatibility with the Lutron dimmer models that have not yet been tested internally. As such, we believe that the Caseta PD-5NE dimmer would be able to function optimally with our power supplies. 

High CRI Dimmable Lighting for Small Room

We are looking to light up a small room we have built. It is around 9x12ft. Currently, we have some edge-lit LED panels (2x4) in there which have low 80 CRI but nice diffuse light and dimmable as well. We are looking to get around 50,000 Lumens of high CRI, Dimmable light. We have some thoughts about using your LED strip lights and a diffuser sheet, but I am worried about the amount of lights, power supplies, and dimmers I would need. 

As every 16.4 ft (5 meter) reel of the 12V or 24V LED Strip Lights provides 7500 lumens, 6.6 reels would be able to provide the requested 50,000 lumens. 

Though each reel would require a dedicated power supply (such as the FilmGrade™ DC Power Supply for LED Strip or TRIAC Dimmable Power Supply for LED Strip), it might be helpful to know that multiple power supplies and product reels can be connected to the same in-wall dimmer, as illustrated within the TRIAC product page. 

​That said, please note that wall-dimmers have maximum wattage ratings. We would recommend ensuring that the products connected per dimmer circuit do not exceed that rating for safety purposes. 

If the DC power supplies were alternatively used, each reel would require a dedicated dimmer, such as the FilmGrade™ Flicker-Free LED Dimmer. 

In the hopes that it proves to be useful for your installation planning, I have attached a link to a LayoutMap below, for an illustration that utilizes multiple power supplies. 

LayoutMaps™ - LED Strip Light Layout 3001-1C

Do you have any type of extruded aluminum channel that I could adhere the LED strip lights in to allow for cooling, and easy of assembly and disassembly? This unit will be taken down to travel to trade shows and re-assembled. 

We can confirm that we sell the Aluminum Channel for LED Flex Strip in both flat and corner versions, which can be helpful for the diffusion of both heat output and light output. 

The aluminum channels have a 13mm internal width, which can be used to apply the 10mm width of the LED Strip Lights within using the preattached adhesive backing. 

By pairing this installation with detachable LED strip connectors, it could be a good option for the aforementioned trade shows. 

​Alternative options may also be available from Klus Design, though we have not personally tested the products they have available. 

Do you have a recommended remote controllers for DMX Dimmer?

I have an application with a single-color LED strip where I would like to use your FilmGrade DMX dimmer but I am looking for a product that I can use to control this wirelessly with a simple remote. Can you make any recommendations? As an alternative, I really just need a very high-frequency PWM controller with a wireless remote but am having trouble locating such a product. 

Unfortunately, we are not aware of any remotes that could be used with our DMX Dimmer and Decoder product, and we do apologize for any impact this might have on your purchase planning. 

That said, there do appear to be several LED Light remote controllers available from third-party stores such as Amazon, though we have not performed compatibility testing to ensure that these remotes would be compatible with our LED Strip Lights.​

Is there a dimmer and filter that would work with the realUV LED Flood Light?

Is there a dimmer that would work with the realUV LED Flood Light? Is there any kind of filter that would cut down the amount of bright visible light emitted by 365nm LEDs? Something like woods glass? These LEDs don’t really visibly illuminate an area, but the LED itself does really stand out. I’d like to disguise it a bit more. 

We can confirm that the realUV Flood Light is not intended to be used with dimmers. As such, performance issues will likely be encountered when utilized with a dimmer product.

​As an alternative, we can confirm that our realUV LED Strip lights are compatible with dimmers, such as the FilmGrade™ Flicker-Free LED Dimmer, or the TRIAC Dimmable Power Supply for LED Strip paired with an in-wall dimmer. 

Though we are not familiar with woods glass, it does appear to be a good option for eliminating the transmission of output above the 400nm visible spectrum. 

​Bandpass filters might also be a good match, and you may also be able to locate transmission-limiting gels available from B&H Photo. 

Do you have a recommended LED dimmer for BR30 bulbs?

I just bought six 60W, 800 Lumen, and 5000K BR30 bulbs for my video production space. What brand of dimmers do you recommend? Have some installed (Lutron I believe) but the dimming range isn't very large. Would like to dim them further. 

​The minimum dimming level for our lamps is generally ~20% or so, so we completely understand the concern regarding the dimming range. We generally test with Lutron and Leviton dimmers and are unfortunately not aware of any specific dimmer models which may improve the dimming range. Some Lutron dimmers do have an adjustment/calibration dial which may help a bit in lowering the minimum brightness.

​Our engineering team is working on improvements to expand the dimming range to 0.1% - 100% and hopes to have this available in a future product iteration.

Would I be able to operate the realUV 365nm and 395nm strips individually and simultaneously?

I am interested in a 3.2 ft strip of each of the two wavelengths and would like to be able to have them separate individually and simultaneously (both straps on at the same time, but also the ability to have them operate independently). What equipment/setup would be needed? 

Based on the details provided, we might recommend an installation that utilizes our DMX Dimmer and Decoder as a hub for both LED Strip Lights. 

The DMX Dimmer and Decoder is a product that can be used to precisely control the output of each connected channel, as well as multiple LED Strip Lights. In the hopes that it proves to be helpful, we have attached a link to the product user manual below. 

Specification Sheet and User Manual

I am interested in setting up two short straps of the LED UV. One strip at 365nm and the other at 395nm. These would be attached to the wall just above a table where I'd like to observe/study banknotes with fluorescent properties. As long as the lights would be powerful enough to shed their special type of light about 2-3 ft or so, then that is all I'd need. 

I just would not know how to install it. Would it come with instructions? Or is it simply another unit that needs to be plugged in and the leads from the two strips would have to be plugged in? Is there a way to call and discuss using it? 

Based on the details provided, we can confirm that the LED Strip Lights can be daisy-chained together using the Daisy-Chain DC Connector for UV LED Strips product. 

This would allow for a low-cost installation utilizing the minimum quantity of power supplies and connectors for the two 3.2 ft (1 meter) lengths of the 365nm and 395nm realUV™ LED Strip Lights. 

So, with 2 strips and the device(s) needed to make the daisy chain work, what would the cost be? Also, would I need any advanced knowledge/skills to install the units? Would installation instructions/guidance be provided?

My main purpose is to have these lights installed to observe and take pictures of banknotes (US and world banknotes) that fluoresce...would these lights (365nm/395nm) do the trick?

Generally speaking, the fluorescent effect upon a target will be strongest with the 365nm version. We have attached an informative link from our website regarding the topic below. 

We have also attached links to two LayoutMaps below, which illustrate the configuration using the realUV LED Strip Lights. These links contain installation descriptions and links to each product featured within. 

What is the Difference Between 365 nm and 395 nm UV LED Lights?

LayoutMaps™ - LED Strip Light Layout 7021_4B

LayoutMaps™ - LED Strip Light Layout 7021_4D

What is the main function of the dimmer? For example, if I connect the dimmer between the power supply and the strip, will I be able to increase/decrease the intensity of a single strip? Control whether multiple strips are either on or off.

Based on the fact that 365nm will generally give better effects for my uses and therefore, rendering the 395nm not as necessary, what would be the cost for the 365nm strip and power supply?

Also, how long does the strip last and are individual cells on the strip replaceable...or dies the whole strip need to eventually need to be replaced?

We can confirm that the dimmer uses a dial to adjust the output (between 0-100%) of the connected LED Strip Light product. 

We can also confirm that the realUV™ LED Strip Lights have a three-year warranty period. If the lights encounter malfunctions during that time, please let us know and we would be happy to help. 

Aside from controlling the intensity of things emitted, what is/are the functions that the Dimmer offers? For example, does it offer the option of adding another strip and allowing to "toggle" between the different light sources and controlling the light intensity of each light strip? My understanding is that without the Dimmer, the light strip and the power unit would just allow one strip to be used and it will be either on or off with additional controls/flexibility especially.

We can confirm that the dimmer only controls the intensity of light output from 0-100%, and is not able to directly target (or “toggle”) the output of individual light strip segments that are connected to it. 

LED Strip Light for Boat Cabin Lighting

I am looking to put ambient, dimmable 12-volt strip led lights on the interior of my sailboat. A five-foot run on both port and starboard sides of the boat interior. What products would suit my needs? 

Before recommending a product, it might be helpful to know that our LED Strip Lights are not IP rated for exposure to moisture or the elements, though there may be third-party insulated channels available elsewhere. 

That being said, the first product that comes to mind is the 12V CENTRIC HOME™ LED Strip Lights for Home & Residential product in 2700K or 3000K. 

This product can be paired with a dimmer such as the FilmGrade™ Flicker-Free LED Dimmer, though your installation may be able to utilize an integrated dimmer onboard the vessel rather than the above in-line dimmer. 

Can I install a dimmer control for Avian Full Spectrum A19 LED Bulb?

Can I install programmable dimmer control for Avian Full Spectrum E26 A19 LED Bulb for Birds? Will it affect the function of the light bulb or will it damage the bulb? I would like to simulate the actual slow sunrise and slow sunset patterns for my bird cage. 

Unfortunately, we can confirm that the Avian Full Spectrum E26 A19 LED Bulb is not compatible with dimmers. As such, utilizing the lightbulb with a dimmer could potentially cause performance issues. 

That said, you might also be interested in our dimmable Avian Full Spectrum E26 BR30 LED Bulb for Birds, though we would encourage you to ensure that the input voltage of 120 V AC, 50-60 Hz is compatible with your local voltage standards. 

What is the brightness of Centric Daylight Strip Lighting at a 3-feet distance?

Can you please tell me what the brightness would be in Lumens at a distance of 3 feet from your PN 3004.50? I need to have 1000 lumens at that distance from the source

Based on our review of the details provided, as well as our IES report data, we can confirm that the 3-foot illuminance value would be approximately 572 lux. As such, we would recommend utilizing two rows of products to reach the 1000 lux target. 

​We have attached a PDF containing the PN 3004.50 IES data below, in the hopes that it proves to be helpful for your installation planning. 

I want to buy the following to try the lighting out as proof of concept and want to be sure I am buying the proper items

1 each 16-foot strip 3004-50

1 each power supply, would that be the 3071?

1 each package jumpers, 3071

Our plan to start will be to outfit a single 8-foot bench so we are cutting it in half and will double the side of the strip by side….

Also, I see you have the 3060 surface mount extrusion but it looks to only fit one LED strip in width. We need two strips to sit side by side…

Do you have an aluminum extrusion that would fit TWO of the LED strips and also comes in longer lengths?

We can confirm that the 24V 5000K CENTRIC DAYLIGHT™ LED Strip Lights (PN3002.50, though please let me know if this is incorrectly listed as 3004.50) are compatible with the 24V FilmGrade™ DC Power Supply for LED Strip (PN3092).

We can also confirm that the LED Strip to Strip Connectors (PN3071) can be used to connect segments of the Centric LED Strip Lights. 

If it proves to be helpful for your installation planning, we have also provided a link to a LayoutMap below for a segmented LED strip light installation. This link contains configuration details as well as links to each of the optional connector accessories. 

LayoutMaps™ - LED Strip Light Layout 3002_2B

As a final note, we do not have channels that can accommodate two parallel strip lights at this time, nor do we have longer channels available, and we do apologize for any impact this might have on your installation planning. 

When do you use the Film Grade power supply and when do you use the 3071 Power supply?

For reference, the PN3071 product in our catalog is the LED Strip to Strip connector, which is used to connect segmented LED strip lights. In case it proves to be helpful, we have attached a link to our full list of power supply products below. 

LED Power & Dimmers

Flicker-Free LED Lighting for Golf Simulator Swing Optix Cameras (Uneekor)

I am purchasing Swing Optix cameras from Uneekor (www.uneekor.com). Their cameras are at 165 frames/sec. They recommended your company for lighting. My question is what type of overhead lighting would you recommend? I am currently building a new home and am installing a golf simulator in the basement with a 10-foot ceiling. From what I have seen, their lighting is above, behind, and at the side of the golfer. The question how much lighting do I need given your experience? 

Based on the details provided, we would recommend the 5600K FilmGrade™ WHITE LED Strip Lights, which are designed with video capture and high CRI in mind. 

By inputting the dimension of the Golf Simulator space into our Lumen Estimation Calculator, including the ten-foot ceiling height, you will be provided with a recommended quantity of products to use in order to achieve optimal illumination. For example, you may only need 9 feet of the LED strip light products, which produce 450 lumens per foot, in order to illuminate a 10x10x10' area with 3,821 lumens. 

​For your installation planning, you might also find value in our Layout Maps, which provide configuration instructions, as well as links to the recommended connectors and power supplies. For mounting the product, you may also be interested in our aluminum channel products. 

I wanted to clarify the space I am illuminating. The lighting is needed to illuminate a golfer swinging a club. There will be a camera directly behind the golfer and another camera looking straight at the golfer. The high speed cameras (145 frames/sec) are used for swing analysis.

I wanted to provide an overhead layout of the golf simulator (attached). I am showing the 5700K Lumen Strip lighting, as you recommended. 

I have a swing camera directly behind the hitting zone (7 ft) and another camera perpendicular to the golfer under the 48" TV. The projector will not be on with filming the swing. 

Is this too much, too little or just right?  

Based on our review, it appears that the illumination area is roughly 4 x 8 feet, and would utilize 16 feet of LED strip lights, which can be accomplished with one divided reel of the FilmGrade™ WHITE LED Strip Lights. 

For other installations that size, we would usually recommend ~2,599 lumens, which could be accomplished with only 6 feet of LED strip lights outputting 450 lumens per foot. By comparison, the mockup installation of 16 feet would output roughly 7200 lumens.

As the installation is designed for filming, having evenly-spaced, inward-directed light from the three sides does appear to be very beneficial, which prevents us from immediately recommending the utilization of fewer segments given the option for dimmer adjustment. 

​There is also the additional consideration that the surrounding area could benefit from additional illumination (via indirect light) in ways that our lumen estimation calculator tool, shared below, would not take into account. By increasing the illumination area dimensions to 7 x 12 feet to account for the immediate surrounding area, we quickly reach the maximum output of one reel (7380 lumens).

Lumen Estimation Calculator

Considering the above, it appears that one reel segmented into three lengths would be sufficient. That said, we would recommend performing pre-installation testing to ensure that the area is evenly illuminated for your video capture. Even if the combined output is too intense, the individual dimmers could easily be used to adjust the output to your preference for video capture. 

I was thinking about using 3 of the 3 m channels that bracket the hitting mat as shown in the layout drawing. These will be at 10 ft high, so I assume using the flat aluminum panels would be the preferred option. All three would be on dimmers.

Based on the layout provided, it does appear that the flat channels would be more useful than the corner channels for your installation. 

​Generally speaking, the corner channels are used for ceiling lines and wall washing, where the flat would alternatively allow for a broader diffusion of light being cast downward from the ceiling. 

Is it possible to have the dimmer switch incorporated into a regular wall gang box? I assume the dimmer switch is the on/off switch as well?

We are happy to confirm that when the lights are powered using an in-wall power supply such as our TRIAC Dimmable Power Supply, they are compatible with most wall dimmers. This includes compatibility with smart home dimmer systems such as Lutron Caseta, which are listed in the below compatibility guide.

In the case of the in-line FilmGrade Dimmer we can confirm that the dimmer also operates as primary power control, though this is not necessarily true when the product is connected to a wall dimmer. 

For your layout planning, we have also provided a configuration link below for the installation of connected LED strip light segments powered by a TRIAC power supply, controlled by a wall dimmer. For connecting the FilmGrade LED strip lights to the TRIAC power supply, you will also need connecters to convert the DC barrel jack plug to wires. 

Compatible Dimmer List

LayoutMaps™ - LED Strip Light Layout 3001-1B

Do you have a LED Dimmer that matches my Lutron Wall Decor switches?

So I get your 3091. Do you have a 3081 that matches my Lutron Wall Decor switches? And what else will I need before I get to my waterproof TAPE strips do you have them? 

As wall dimmers are usually incompatible with DC-Plug power supplies, we might instead recommend utilizing the TRIAC Dimmable Power Supply for LED Strip for in-wall power in the event that using a wall dimmer is preferable for your installation.

We can confirm that the TRIAC power supply has been tested as compatible with many of the Lutron dimmers on the market. Additionally, we would also recommend making sure that the TRIAC power supply matches the voltage of the LED strip lights. 

That said, please note that our LED strip lights and other products are not waterproof, or IP-rated for protection against the elements. If these products come in contact with moisture, they may cause an electrical hazard and void the warranty. 

Does Lutron Radio RA2 Compatible with TRIAC dimmable power supplies?

I'm hoping you would have some information regarding compatibility with Lutron's Radio RA2 dimmers with your TRIAC dimmable power supplies + 95 CRI LED strip lights. I see that they work with Caseta Dimmers, is there an RA2 dimmer that is preferred? 

Though we have not tested the Lutron RA2 against our TRIAC dimmable power supply, we can confirm that it utilizes the forward-phase mode that our power supply is compatible with. As such, we would expect that the Lutron RA2 dimmer would be functional with our in-wall power supply. 

​In case it proves to be helpful, we have attached a link to our dimmer compatibility document below: 

Compatible Dimmer List for CENTRIC SERIESTM LED Power Supply

Does your ABSOLUTE SERIES™ LED Flexible Strip dimmable?

I want to make absolutely sure this product is dimmable: ABSOLUTE SERIES™ LED Flexible Strip - 99 CRI - 16 ft / 5 m Reel Also, what amount of wattage is recommended for a total of 3 strips, and do you have a wiring design recommendation? 

We can confirm that the Absolute Series LED strip lights are dimmable when paired with a compatible dimming power supply, such as our 12V TRIAC Dimmable Power Supply for LED Strip or the FilmGrade™ DC Power Supply for LED Strip. 

As each foot of the LED strip lights requires 4.2W, one full 16.4 ft reel would require 68.88W. That said, please note that the LED strip lights have a maximum combined length of 16.4 feet, meaning that powering uninterrupted lengths greater than 16.4 feet will cause voltage drop and will prevent optimal output. 

Given the above, we usually recommend utilizing one power supply per full reel, though you also have the option of connecting wire segments totaling less than 120W of power draw in parallel to one power supply. 

We have attached a few configuration layout guides below, which I hope prove to be helpful for your installation planning. The first two guides utilize the DC power supplies, where the latter uses in-wall power and will likely require the Female DC Barrel Jack Plug Adapter. 

LayoutMaps™ - LED Strip Light Layout 3002_3E

LayoutMaps™ - LED Strip Light Layout 3002_3D

LayoutMaps™ - LED Strip Light Layout 3001-1C

I plan to wire twelve 4' sections in parallel (48' total). I see in the response that you are recommending having an independent power supply for each 16.4' section, however, if I use a 320W 12V supply, should that not be enough to power all 48'?

Utilizing a higher capacity power supply could indeed be a good solution for your installation, so long as the LED strip lights are run in parallel due to the aforementioned maximum run length of 16.4ft. 

We would also recommend ensuring that the amperage of the power supply is sufficient for providing current to that quantity of product. We have attached a link to the Absolute Series LED strip light product specification sheet below, which includes a guide for power supplies, in case it proves to be helpful. 

ABSOLUTE SERIES™ LED Flexible Strip Specification Sheet

So if I have three full reels, how many amps are required? The spec sheet only hits up to one full 16.4 length. Does the requirement increase by 3x?

As each full 16.4 ft (5 meters) reel requires 6 amps at 12V, I can confirm that three full reels would require a power supply capable of outputting 18 amps. 

How many LED strips do I need to provide some indirect lighting for the 20 ft x 30 ft space?

I need help to determine which products to buy for my project. The space is around 20 ft x 30 ft with three areas of windows (one located off the picture to the right). I will be placing a 100-watt LED in the dormer that you can see in the photo and a 270-watt (3-light) fixture in the stairwell that you can see in the photo. My plan is place to LED strips on top of the beams in the center of the room. 7 beams are 8 feet long. The end beams are about 6 inches from the ceiling and the middle beams are about 3 feet from the top of the ceiling. The light currently on the beams will be removed and not replaced. I need assistance in figuring out how many LED strips I need to provide some indirect lighting for the middle of the room and what products I need to purchase to directly wire the LED strips to a dimming wall switch. 

By using our Lumen Estimation Calculator, it appears that the room would be fully illuminated with ~13,744 lumens, which can be achieved by using 31 total feet of our LED strip lights, which output 450 lumens per foot.

For this installation, we would recommend utilizing two full 16.4 ft (5 meters) reels of CENTRIC HOME™ LED Strip Lights for Home & Residential, which are available in the most common color temperatures for living areas, 2700K and 3000K. If cooler color temperatures are preferred, we have provided an infographic regarding color temperature selection below. 

To use two full reels, we recommend utilizing two units of the 12V TRIAC Dimmable Power Supply for LED Strip, as each 12V reel requires 90.2W (at 5.5W per foot), and each power supply can offer 120W. I can also confirm that multiple power supplies can be connected to the same wall dimmer.

We have also provided a few links to our Layout Diagrams below, which list the required accessories for each installation type. For a list of our compatible wall dimmers, please reference the below document.

Which LED Light Color Temperature Should I Choose?

LayoutMaps™ - LED Strip Light Layout 3001-1C

LayoutMaps™ - LED Strip Light Layout 3001-1B

For mounting the LED strip lights, we would recommend utilizing a set of flat aluminum channel products, which would allow for the lights to diffuse upwards towards the ceiling, allowing for indirect light. 

I just measured the space again and what I would like to do is to put an 8' strip on the middle ceiling beam and three 4' strips on the three beams on either side of the center beam. This would equal 32' in total length - 4',4',4',8',4',4',4'. Based on this design I am thinking that I could order two 16' reels (12v or 24v?) and cut them into sections. Can you help me determine how to wire this? Also how many power supplies I would need for this design? Lastly, I am curious about the junction box option for the power supply.

Based on the details provided, I might recommend utilizing a 24V installation, as it would be less prone to voltage drop. For more information about the differences between the 12V and 24V options as well as voltage drop, we have attached a few informative blog posts below. 

We have also attached an illustrated layout below, which we hope proves to be helpful. In this configuration, the installation has been evenly divided across two power supplies and connected in parallel. 

​As each foot of the 24V LED strip lights utilizes 5.5 watts of power, 32 feet would require 176 total watts. By dividing the layout in this way, each side would require only 88 watts and 3.8 amps, which can be easily provided by each power supply. 

Advantages of a 24V LED system vs 12V

Connecting LED Strips in “Series” vs “Parallel”

Additionally, the two power supplies could be connected to a single wall dimmer, as illustrated in the below diagrams. These LayoutMaps also include links to the recommended connectors and power supplies that you might need. 

LayoutMaps™ - LED Strip Light Layout 3001-1C

LayoutMaps™ - LED Strip Light Layout 3001-1B

What size wire should I be using to connect the strips to the power supply? Note that the power supply will be placed behind a wall thus the wire will be connected through the wall. I am not sure if that impacts the wire size. 

Generally speaking, we recommend utilizing 16 AWG wires for connection between the lights and power supplies, which are sold on our storefront. Further, we might recommend checking with an electrician to be sure that the gauge is sufficient for your in-wall installation. 

16 AWG Wire for LED Strip Lights - 33 ft / 10 meters

Dimmable and Flicker-free Lighting for Video/Photo Studio

I'm a videographer and I'm in the process of helping our contractor to convert an existing office space into several small video/photo studios as well as multi-person editing suite. 

Our needs are for the studio lighting to be daylight balanced (ideally 5600K), dimmable, and flicker free. 

1) Would this power supply allow flicker-free dimming using a standard wall dimmer from your dimmer compatibility list (e.g. LUTRON SCL-153PR-WH, LUTRON DVCL-153PR-WH) or would it require your FilmGrade Flicker-Free LED Dimmer?

2) Are your aluminum channels suitable for being suspended from a ceiling rather than directly mounted to a flat surface? If so, do you have any guidance on how that might be done? If not, are there any fixtures that you could recommend that are compatible to be fitted with your LED strips?

3) Finally, do you have any suggestions for how LED strips might be incorporated into a drop ceiling? 

We are happy to confirm that both of the referenced Lutron models have been tested as compatible with our power supplies. For a full list of compatible dimmers, please reference the document linked below. 

We can also confirm that we have not had any experience with suspending the aluminum channels from the ceiling as a lighting installation before. As such, we unfortunately might not have any helpful advice for this installation type. 

​As an alternative, you may be interested to know that our T8 LED tube lights feature the same LED technology as the LED strip lights. Further, we are introducing a line of LED-ready T8 fixtures that are designed for office and workspace installations.

We have also provided a link below to our Lumen Estimation Calculator tool, which can be helpful for determining the lumen requirements for different spaces.

Compatible Dimmer List for CENTRIC SERIES LED Power Supply

Is your flicker-free dimmer compatible with other brands of light strips?

I have about 100 meters of CRI 95 LED strips already. Is your flicker-free dimmer compatible with other brands of light strips? Assuming I would have to convert power connections. 

Though we have not tested our dimmer with third-party LED strip lights, so long as the lights and connected power supply are able to utilize barrel-jacks, or barrel-jack adapters, we would not expect compatibility issues. 

That being said, there may be hardware limitations of the LED chips or power supplies that might limit the dimming range between 0-100%. For example, in some instances LED strip lights may only be able to dim to a low of 4% brightness. 

LED Strip Wall Dimmer Compatibility

I have a Waveform CENTRIC HOME 24V light strip that I'd like to connect to a 120V wall dimmer. I spoke to Lutron but I am not confident that I got the right answer. I was told that there is only one compatible dimmer (DVRP-253P). I was hoping I could get a confirmation or your assistance in choosing the right dimmer and the right dimmable power supply.

We are happy to confirm that our TRIAC Dimmable Power Supply is compatible with many smart dimmers such as the Lutron Caseta system.

In the event that you know the exact Lutron model number, I have provided a link below to the list of dimmers that are compatible with the above power supply. If you are able to locate your Lutron system in the below document, then it would be safe to assume that the Lutron system is compatible with our LED strip lights and the TRIAC dimmable power supply.

Dimmer compatibility list for Waveform Lighting PN 7093/7094

Do I need a forward or reverse phase dimmer for the strip light? Any other technical info that will help me determine compatibility?

We are happy to confirm that when utilizing the TRIAC dimmable power supply, our LED strip lights are compatible with forward-phase, ELV/reverse-phase, and MLV dimmers. Most of the tested dimmers are forward-phase dimmers and the list of tested dimmers can be found below:

Dimmer compatibility list for Waveform Lighting PN 7093/7094

The dimmer that Lutron recommends DVF-103P is not in the compatibility list. They guarantee dimming performance if I use their driver L3D0-96W24V. Can you please confirm that both driver and dimmer are compatible? 

We are happy to confirm that our dimmable power supply is designed to work with all phase dimmers on the market, which includes the referenced DVF-103P dimmer. 

Though the DVF-103P product is not listed in the compatibility sheet, it might be helpful to know that this is simply the list of dimmers that we have internally tested for compatibility. As such, this list is not exhaustive. 

We can also confirm that we expect to receive an updated dimmer compatibility list by the end of next month, in case an updated resource is beneficial for your installation and purchase planning process. 

LED Lighting Setup and Accessories for Research Project

I’m looking to purchase a few lights for a vision accessibility study. I’m looking to get a few light strips that can all be controlled by a single dimmer switch. After looking through your products I was thinking the following would work, but I want to make sure it’s correct.

Connected the following way:

Power supply -> dimmer -> adapter -> wire -> light strip 1 -> wire -> light strip 2 

Is this the most cost-effective setup?

Based on my review, the configuration provided does indeed appear to be the most cost-effective layout. Though the Absolute Series D65 LED Strip Lights are less expensive per foot of product than the 5-Pack of linear modules, your configuration may not necessarily require 16.4 feet of strip light product.

The only optional addition that we could recommend would be the WAGO board-to-board connectors, which can be helpful with some installations.

Additionally, you may find value in the below installation guide for the absolute linear modules.

LED Strip Light and Accessories for Under Cabinet Lighting

I would like to buy all the things I'll need to set up LED under cabinet lighting. The electrical is already run on a 3-way switch. I want to make sure I'm getting everything I need, but not more. I thought I would need three power supplies, but hubby says one will do.

For starters, the quantity of power supplies required for an installation is generally defined by the total amount of product that requires power. 

​For example, the majority of our LED strip lights utilize 5.5 watts per foot, for a total of ~90 watts per 16.4 ft reel. As the TRIAC dimmable power supplies offer 120 watts of power output, we would then recommend one dedicated power supply per reel.

That being said, it might also be helpful to know that each reel of LED strip lights has a maximum combined length of 16.4 feet, which means that powering more than 16.4 feet of product with a single power supply is discouraged, as it may overload the product, or prevent optimal output per LED.

​As such, if you have a known quantity of LED strip light products that your kitchen requires, finding out the ideal power supply quantity should be fairly easy. If the total amount of lights is not known, we have provided a link to our lumen estimation calculator below, which can provide insight into the amount of light output that the kitchen might require based on the room dimensions.

We have attached a few additional links from our website below, including a link to the interactive layout section of our website which provides multiple configuration illustrations and links to each of the recommended power supplies and connection accessories.

Are your Absolute Series LED Strips dimmable?

I'm excited to be installing your Absolute LED strips but am noticing the product details don't mention dimming at all. Would be using one of your dimming power supplies attached to a Lutron wall dimmer, just want to be sure it'll work. 

We are happy to confirm that our LED strip light products, including the ABSOLUTE SERIES™, LED Flexible Strip product, are dimmable when paired with a compatible dimming power supply, such as our TRIAC Dimmable Power Supply for LED Strip. This is due to the treatment of power that the power supply provides to the lights, which is then adjustable via the dimmer. 

We have attached a link below for the list of wall dimmers that the TRIAC power supply is compatible with. This list includes many Lutron dimmers, which would lead me to believe that the configuration is likely compatible with your Lutron wall dimmer.

Do we need an electronic transformer to avoid the LED Strip from blinking?

We would like to control 24V LED strips with a combined power draw of 800-1000W (part #3002.56) from one location. The LED strips are wired in parallel to minimize voltage drop and are well below the maximum length (more than 50% lower). We have verified they work correctly using a test on a subsection of the circuit using one of your power supplies (part 3092). 

However, when we switch to a 1000W magnetic low voltage power supply (Seagull Ambiance) we get flickering - more like blinking on and off because of the slow rate. We have tried several magnetic power supplies with no luck; do we need an electronic transformer to avoid blinking? If so do you have recommendations on a manufacturer? We would like to be able to add dimming capability through a dimmer at some point. 

Based on the information provided, I believe that our LED strip lights are installed correctly. As you mention, since they are connected in parallel and none of the LED strip sections are exceeding their max run length limits, it does seem that there is a compatibility or performance issue with the Seagull Lighting transformer.

We did a quick search for the Seagull Lighting 1000-watt transformer and was unable to locate any detailed specification sheets. It does seem, however, like an older product designed for incandescent lamps and not LED lamps. The reason this could be significant is that incandescent lamps typically use AC power, while LED lamps are designed for DC power. (If you have any additional detailed manufacturer documentation, please let me know and I'd be more than happy to review it.)

If my hunch is correct that the Seagull Lighting product outputs 24 volts AC, and not 24 volts DC, this may explain the blinking behavior you are seeing. This is because 24 volts AC is actually an average voltage rating (called RMS) and at certain points in the AC sine wave cycle, the input voltage actually far exceeds 24 volts (approximately 34 volts at the peak). During these peak voltage input timeframes, the LED strips are overdriven and exceed their rated power draw (> 1000 watts), potentially leading to the blinking behavior you are seeing.

Our recommendation would be to double-check the voltage rating and ensure that the 24 volts output by the Seagull Transformer is DC and not AC. If it is AC, we would recommend using an alternate solution that uses DC output.

You mention this is for a photo booth application, so in addition to avoiding magnetic drivers (which introduce line voltage flicker at 60/120 Hz), we would also recommend making sure you avoid PWM-induced flicker by choosing a flicker-free (high PWM frequency) power supply solution.

We do have several electronic DC power supply units with flicker-free output which may be of interest. The downside is that the power supplies are limited to 96 watts of output each (to meet Class 2 limitations) but each power supply can be connected to the same dimmer switch by connecting them in parallel. Below are product and layout configuration links that you may find helpful:

https://www.waveformlighting.com/layoutmaps/3001_1C

I have ordered some alternate supplies. Unfortunately, I need something bigger than what you offer but I am trying to get as high a PWM frequency as possible. I have two driver units on order and will test them in actual still photography settings. We have been and will continue to order lots of LED reels from you. 

​As you mention, we unfortunately limit the output of each power supply to 96 watts to meet Class 2 limitations, so while our products would be a perfect fit from the perspective of high PWM frequency dimming, the only workaround would be to use multiple power supplies connected in parallel.

FilmGrade LED Strip Light Accessories For Display Case

I have two IKEA DeTolf display cases and would like to run your FilmGrade WHITE (tungsten) LED Strip Lights vertically along the front of the display cases (5ft up on the left side, with about 15" gap/wire as it crosses the top, and then 5ft back down the right side. I would also like to incorporate your flicker-free dimmer. Power would come from a regular 120V outlet. What accessories would you recommend? Also, as the total length used in this case would be 20ft (5ft x 4), do you offer that length? What would you suggest? 

Based on the details provided, we might recommend two 16.4 ft reels of the LED strip light products. As it appears that the 5600-6500K options are common color temperatures for display cases such as the IKEA DeTolf, we would recommend the FilmGrade™ WHITE LED Strip Lights.

We would also recommend the FilmGrade™ Flicker-Free LED Dimmer alongside the 12V (or matching voltage) of the FilmGrade™ DC Power Supply for LED Strip.

As the LED strip reels contain pre-attached barrel jack adapters, no additional accessories would be necessary beyond the LED Strip to Strip for connecting the segments. We have attached a diagram from our website below, which we hope proves to be helpful for your installation plans.

​Layout Diagram: https://www.waveformlighting.com/layoutmaps/3002_3D?px=-2260&py=-2231.5&pw=1488&ph=1463&s=0.09893617021276596

The LED Strip to Strip product you recommend appears to have a Wire length of 5.9 inches, whereas I would need approximately 15 inches. Do you have that length? You recommend a Flicker Free dimmer and a DC power supply. Would that work to power and dim both cabinets? Do you have a wiring diagram that would show how to power and dim two cabinets of light that would each have a 5ft strip + 15inch wire + 5ft strip?

If a longer length is needed, we might alternatively recommend utilizing a combination of the 16 AWG Wire for LED Strip Lights and the LED Strip to Wire accessories.

As 10 feet of LED strip lights would utilize 5.5 watts of power per foot for a total of 55 watts, one power supply, and one dimmer should be more than sufficient for your installation without reaching the 120W output maximum of the power supply. 

​We have attached two additional layout diagrams below, which show a configuration of LED strip light segments that are connected with the above accessories. Please note that the primary difference between the FilmGrade LED strip lights and the product in the first link below is that the FilmGrade product contains pre-attached barrel jack adapters. As such, no wiring adapters would be necessary for connection to the dimmer and power supply.

Do I need the Flicker-Free Dimmer?

I have an inexpensive LED RGB light strip installed on a video set that came with a remote dimmer. I've found that I get flicker in the camera even at full light output. I found a shutter angle on my camera that minimizes the flicker, but it's still visible. I'm wondering if running it through your Flicker-Free LED Dimmer would improve the issue, or not since there is a flicker even at full output? 

Generally speaking, the power supplies create the flicker-free output by treating the power being provided to the LED strip lights, where the flicker-free dimmer controls the output.

As such, we would likely recommend trying a flicker-free power supply such as the FilmGrade™ DC Power Supply for LED Strip or the TRIAC Dimmable Power Supply for LED Strip.

Compatible Power Supply and Dimmer for LED Strip

I am in the process of building a house with lots of LED strip lighting and would like to use your FilmGrade series in 3,200K and your Centric Daylight Series in 4,000K. I believe I can use these two dimmable power supplies. It isn’t quite clear to me what the difference between these two is. Could you please recommend a product? Also, in the list of compatible dimmers that are available for both of these power supplies, I did not see the Lutron Sunnata dimmer STCL-153PH-WH. I would expect this dimmer to be compatible. 

The primary difference between these two items can be found in the product dimensions, as the Centric Series power supply has a smaller footprint which can be helpful for some installations that have less available space. The secondary difference is that the TRIAC can offer 120W of 12V power, whereas the Centric can offer 96W of 12V power.

Compatibility-wise, we can confirm that either will work well with any of our LED strip light products and can provide flicker-free functionality.

Further, the Lutron Sunnata STCL-153P was tested and confirmed for compatibility. Please see the below document.

https://www.waveformlighting.com/datasheets/CD_3093.pdf

TRIAC Dimmable Power Supply Output Signal

Supply for LED Strip to convert signals and power to a custom low-voltage controller. I would like to inquire as to what the actual output signal is of the device; is it a constant 12V PWM (pulse-width modulation) signal, where the time-on and time-off are equal when the dimmer is set to 50%?

We're happy to confirm that the output signal of the TRIAC dimmable power supply will be a constant 12V at 50%, where the time-on and time-off are equal. Further, when the dimming is set to 25%, then the time-on would be 25%, where the time-off would be 75% per cycle.

LED Strip Light for UnderCounter Lighting

I need a 4’ length. The order description says 16’. Can I use it in different places? One would be hard-wired and the others would be plugged in. I can’t tell you how to order that. Or can I order just 4’ long hardwired?

We can confirm that most of our LED strip lights are sold in increments of 3.2 ft (1 meter) and 16.4 ft (5 meters), and can be segmented but cut the product at the designed cut-points as illustrated on the product specification sheets. Each segment can be individually powered, either by utilizing a DC plug or through in-wall wiring with a power supply. 

We have provided a few layout diagrams below, which illustrate each method described. Depending on the LED strip light product preferred, the accessories and connectors may be slightly different. That said, the below guides contain links to all of the recommended accessories.

LayoutMaps™ - LED Strip Light Layout 3001-1A: https://www.waveformlighting.com/layoutmaps/3001_1A?px=-2244&py=-2231.5&pw=1488&ph=1463&s=0.1

UV LED Strip for Exposure Box to Make Cyanotype Prints

I am making a UV exposure box to make cyanotype prints. It requires 350-400nm of UV light output. The box is 2 feet long. I would like to know what I need to buy from you to make 4 or 5, 20-inch strips. Please let me know if I can use a power supply from an unused hard drive or if I need to buy a power supply specific to your LED strips. Please let me know how many connectors I would need to put this all together. 

Based on the details provided, we would recommend purchasing 5 or 6 units of the 16.4 ft (5 meters) reels of the 365nm realUV™ LED Strip Lights, depending on the total quantity of strip lights required.

As each 12V DC power supply is capable of powering one full reel, we would recommend utilizing one power supply per 16.4 ft of realUV LED strip lights in your installation. Further, please note that the LED strip lights have a maximum combined length of 16.4 feet. Unfortunately, it would be difficult for us to know whether the hard drive power supply mentioned would be compatible, without knowing more about the output.

We have provided two layout diagrams below, which provide more information regarding the connectors, accessories, and power supplies to use for each installation type. The first version utilizes the built-in daisy chain adapters, while the second diagram utilizes strip-to-strip connecters between each segment.

LayoutMaps™ - LED Strip Light Layout 7021_4B: https://www.waveformlighting.com/layoutmaps/7021_4B?px=-2244&py=-2231.5&pw=1488&ph=1463&s=0.1

LayoutMaps™ - LED Strip Light Layout 7021_4C: https://www.waveformlighting.com/layoutmaps/7021_4C?px=-2252&py=-2231.5&pw=1504&ph=1463&s=0.125

I need the info on the width of this, about the 2 types of UV- LED offered and which connectors to order please.

We can confirm that in order to have 80-100 inches of product in order to create 4 or 5 20-inch lengths, or alternatively 6 or 8 2-foot lengths, a single 16.4 ft (196.8 inches) reel should be able to provide more than enough product. As such, this installation would likely only require a single power supply.

Regarding the product dimensions, we can also confirm that the realUV™ LED Strip Lights have a diameter of 10mm. The full dimensions can be found within the 'mechanical specifications' section of the product specification sheet.

In order to connect the realUV™ LED Strip Lights to a power supply, you can either utilize the preinstalled barrel-jack adapter on the product or utilize a barrel-jack adapter and LED Strip to Wire product. Further, to connect the individual segments of the LED strip lights, you can utilize the LED strip to strip.

We have attached a link to a blog post from our website below, which illustrates the differences between the 395nm and the 365nm output. That being said, based on the details provided we would recommend the 365nm version for your installation.

What is the Difference Between 365 nm and 395 nm UV LED Lights?: https://www.waveformlighting.com/tech/what-is-the-difference-between-365-nm-and-395-nm-uv-led-lights

For more information regarding the installation options, the previously provided 'Layout Diagrams' include configuration descriptions, as well as product links for each of the required and optional accessories that are used for connecting the strip light segments and power supplies.

LED Strip Configurations for Office Lighting

I want to light my office with this LED strip: 

ABSOLUTE SERIES™ LED Flexible Strip

Is it possible to connect more than one strip to this power supply? 

FilmGrade™ DC Power Supply

The office is 8' x 8' and I want to build a soffit near the ceiling. I intend to line the inside of the soffit with these strips with the lights facing out into the room. I need 2x 16' strips to make it around the room. I want to use the film-grade dimmer (I have one). 

We typically recommend utilizing one power supply per 16.4 ft (5 meters) reel of LED strip light products, as the power supplies would not be able to afford sufficient power for more than one reel.

As a further consideration, the LED strip lights have a maximum combined length (defined by the hardware) of 16.4 feet. As such, powering additional lengths can lead to performance issues.

Due to this, your installation might benefit from using a second dimmer, or alternatively utilizing a single in-wall dimmer and in-wall power supplies such as the TRIAC Dimmable Power Supply for LED Strip.

We have attached a link to a layout diagram below, which we hope proves to be helpful for your installation planning. This page also contains installation suggestions and links to the recommended accessories.

LayoutMaps™ - LED Strip Light Layout 3002_3D: https://www.waveformlighting.com/layoutmaps/3002_3D?px=-2244&py=-2231.5&pw=1488&ph=1463&s=0.1

LayoutMaps™ - LED Strip Light Layout 3002_3E: https://www.waveformlighting.com/layoutmaps/3002_3E?px=-2244&py=-2231.5&pw=1488&ph=1463&s=0.1

So, each 16' strip would require one in-wall power supply and an in-wall dimmer?

So my setup would look like this:

(2) 16' LED strip

(2) In-wall power supply

(1) In-wall dimmer

Can you recommend a good dimmer? Will the dimming be as good and variable as the 'film-grade dimmer?

We can confirm that each reel would require a dedicated power supply. I can further confirm that the TRIAC dimmable power supply is compatible with forward-phase, ELV/reverse-phase, and MLV dimmers. 

Power Supply Requirement for third party UV LED Strip

I have two reels of 5-meter 12v UV LEDs that need 14 watts per meter. I have the Waveform FilmGrade Dimmer and a Waveform 12v Filmgrade power supply. Do I need two of your 12v power supplies (meaning I'd split the two 5m reels into two separate portions, each with their power supplies) to get proper consistent output from all 10 meters of lights, or could I get a single 24v Filmgrade Power supply, or some other setup, as I do want to be able to use the dimmer? 

Based on the details provided, we would recommend utilizing two 12V power supplies to power the two reels of the UV LED product.

As the LED strip lights draw 4.5 watts of power per foot for a total of 72 watts per reel, the 120W power output of the FilmGrade™ DC Power Supply for LED Strip would not be able to support two full reels. Further, please note that the LED strip lights have a maximum combined length of 16.4 feet (5 meters). As such, we would recommend powering each reel independently. 

As the LED strip lights are designed with specific voltage in mind, we do not recommend using a 24V power supply with the 12V products, as it could cause product failures and void the product warranty.

LED Strip Light for Bathroom Renovation

I am considering having my electrician install a Waveform Centric Home LED strip light during a bathroom reno. 

Do I have everything I need if I order PN 3070, PN7094, PN 7095, and the Centric Home LED light strip? 

The light strip will be located 7-9 feet away from the power source. Is there enough wire included (I thought I read somewhere on your site that there are only 59 inches of wire with the light strip?). Or is this something the electrician would supply? 

We have attached two layout diagram links below for the Centric Home LED Strip Lights product, which contains itemized lists of all of the recommended connectors, power supplies, and accessories for those installations.

LayoutMaps™ - LED Strip Light Layout 3001-1B

LayoutMaps™ - LED Strip Light Layout 3001-1A

Though the PN3070 LED strip-to-wire is recommended for connecting the wiring to the LED strips, as well as a high gauge wire such as the 16 AWG wire, the female and male DC power adapters (PN7094, PN7095) are likely unnecessary unless a DC-plug power supply is being used for power, as the in-wall TRIAC dimmable power supplies connect to the LED strip lights directly with wiring.

Regarding the distance between the power supply and the LED strip lights, though you may encounter a small amount of voltage drop at 7-9 feet of distance, I do not believe that it would be enough to cause performance issues. If it proves to be helpful, I have attached a link below to our voltage drop calculator tool.

Voltage Drop Calculator: https://www.waveformlighting.com/tech/led-strip-light-wire-gauge-calculator-requirements

Absolute LED Strips with PSU and Dimmers for Photographing Fabrics

I´m thinking about ordering two Absolute LED strips with PSU and Dimmers for photographing fabrics. Also 8 LED bulbs. 

I just bought a Aputure 300x bi-color LED (300w) fixture and although it's a very nice and flexible LED I'm not happy with the green tint at daylight and the yellow tint at low kelvin settings. I guess one Absolute 6500 k LED (5 meters) and one Absolute 5000 k LED (5 meters) would be great for getting both a nice working light and two dimmable lights at slighty different tempetures, right? (I have soft boxes for diffusion).

Based on the details provided, we believe that the 5000K and 6500K Absolute series LED strip lights could great options for your photography installation.

As alternatives, you might also be interested in the FilmGrade line of LED strip light products, which are available in the 3200K and 6500K color temperatures, which are often used for photography and film capture.

For flicker-free, dimmable installations, the aforementioned LED strip light products are often paired with the FilmGrade™ DC Power Supply for LED Strip (compatible with global input voltages of 100 - 240V AC, 50-60Hz) and the FilmGrade™ Flicker-Free LED Dimmer product. Please note that we recommend ordering a power supply and strip lights of matching voltage (12V or 24V) for compatibility.

If I would want some more power than what I’m getting from one 5 m absolute led, what would you recommend? I want the cleanest colors

We're happy to confirm that the Absolute Series of products offers the most color-accurate output among the items in our catalog. As the product offers a CRI of 99, the light output will be virtually indistinguishable from natural daylight.

We have provided a link to the product photometric report below, which contains data on the output produced.

5000K Photometric Report: https://www.waveformlighting.com/photometrics/TR_7001.50.pdf

6500K Photometric Report: https://www.waveformlighting.com/photometrics/TR_7001.65.pdf

We can also confirm that the 16.4 ft (5 meters) Absolute Series LED strip light offers 1250 lumens per foot, for a total reel output of 20,500 lumens. If more lumens are required for your installation, we may recommend purchasing more than one reel.

LED UV Dimmer Mode that Works as a Fader

I'm looking for a LED UV dimmer mode that works as a fader, automatically going from 0% to 100% back to 0% and keeps repeating. Do you have such an item? 

Unfortunately, we do not have any products that can automatically adjust the light output of the LED strip light products at this time.

As an alternative, you might be interested in the FilmGrade™ DMX LED Dimmer & Decoder with 5-Channel Output product, which can be paired with a third-party DMX controller for granular control of the light output.

Flicker-free and Dimmable LED Bulb for Poultry Farm

I am having an issue right now with low-quality LED light. The chickens are getting extremely nervous because of the flickering. I have tried many lights, and have changed my light controller with specific LED controllers. The chickens are so nervous that I am starting to see some mortality because of that. I need a 100% dimmable, flickering-free LED bulb. Is there any recommendation you could give me?

Although we do not currently have any bulb products which are both flicker-free and dimmable, we do wonder if an installation utilizing our high-CRI LED strip light products is an option for your poultry farm.

Our LED strip light products can be both flicker-free when paired with our DC-plug or in-wall power supplies, and are also compatible with dimmers. These products are also available in a wide variety of options, including the 99CRI ABSOLUTE SERIES™ LED Flexible Strip product, which is designed to closely simulate the light output of natural daylight.

​Though the installation would likely be slightly more involved than one utilizing light bulbs, I would be more than happy to provide you with more information and configuration resources in the event that this was of interest.

Can I connect the ground wire to the DMX LED Dimmer input ground?

I am wanting to try using this LED dimmer controller for one of my light fixtures. The light fixture I have has two wires: (the PWM control wire and the ground wire). Would it be okay if I connect the ground wire to the DMX input ground?

Our DMX decoder is not designed to be compatible with residential or commercial lighting fixtures. As such, it does produce any PWM-based dimming signals. It sounds like your LED controller is not DMX compatible and would not be a good fit here.

The lighting fixture that I am trying to control is described here: This lighting fixture has 3 wires and is controlled by PWM:

Wire1: 850nm, Wire2: 940 nm, Wire3: ground

Regarding the DMX decoder, I tried measuring the output but I didn’t see any changes on the oscilloscope. I tried measuring the PWM from 5/W2, 4/W1, 3/B-, 2/G-, and 1/R-. 

In addition, I tried changing the settings manually such as PF01 to PF30, and 1-00 to 1-99…etc but didn’t notice any changes in the output.

I think I should be able to see PWM. Am I measuring the output incorrectly? What is the correct way to measure the signal from this device?

Unfortunately, we weren't able to see any technical information on the PWM input requirements so I'm not sure if I can provide any further assistance here concerning this product. If the manufacturer has some additional datasheets or information they can provide, that may be helpful for us to better determine this.

For example, see below for the Meanwell HLG power supply, which provides detail on the 10-volt PWM input requirements (middle chart, page 4):

https://www.meanwell.com/Upload/PDF/HLG-240H/HLG-240H-SPEC.PDF

We do suspect that the CMVision product has some special requirements for dimming and the manufacturer may be better equipped to provide assistance with the necessary accessories and components.

​Otherwise, we suspect that our DMX decoder product is not compatible with the CMVision product you have linked to, and do apologize for the inconvenience. 

Can I make FilmGrade™ Flicker-Free LED Dimmer Programmable

I'm developing an environmental chamber for lab experiments and I'm interested in using the ABSOLUTE SERIES™ LED Flexible Strip - 99 CRI. The only issue is that I need to incorporate flexible dawn-dusk dimming. Is there a way to incorporate a programmable feature with this light strip or to make the FilmGrade™ Flicker-Free LED Dimmer programmable? 

As the FilmGrade™ Flicker-Free LED Dimmer product contains a physical dial for adjustment, it is unlikely to be compatible with an automated system where it assists in adjusting the output.

That being said, you might alternatively be interested in our FilmGrade™ DMX LED Dimmer & Decoder with 5 Channel Output product, which can be paired with a third-party DMX Controller for programmable output and granular lighting control. 

DMX LED Dimmer & Decoder in Setting Up a Preprogram Scenes

I am setting up the Waveform 3082 controller with 5 channels (Maybe 10 channels with 2 3082 controllers) of White Light Film Grade LED strips. I want to be able to preprogram different static intensity levels of each channel which can be switched easily switched to another pre-programmed set of intensity levels by computer of a button push. I would like to be able to set up about 5 different preprogrammed scenes that can be chosen easily by an untrained person. The DMX controllers that are available have capabilities well above what I need. I could program a Rasberry Pi system that could do what I need but I rather not spend the development time if there is a simple solution available that would meet my need. 

We understand the request and use case, and this may indeed be a bit of a challenge given the constraints on development/set-up time and user interface complexity.

​​As you mention, the DMX decoder/dimmer (PN 3082) does not have any custom preset functionality, so the only way to effectively utilize this component for your installation would be to have some kind of DMX controller input.

While we have not tested this on our end, we are aware that several DMX-to-USB products exist, which may allow you to have a simpler "software" interface on the PC side compared to the more commonly seen DMX controllers used for theatrical and stage lighting applications.

One "analog" alternative would be to utilize our PN 3081 dimmers which have analog dimmer setting input dials with brightness setting markers. This would likely be a more costly solution since you will need one dimmer per LED strip reel but perhaps could be worth considering if a simple and intuitive setup is preferred.

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.

LED Flex Strips and Accessories for Under Cabinet Lighting

I am interested in Waveform LED Flex Strips for under-cabinet lighting in our kitchen and have a few questions. 

Can the strip-to-strip and strip-to-wireless solderless connectors only be used with Centric Home or Daylight LED Strips, or can they be used with FilmGrade White & Hybrid Strips?

The strip-to-strip connectors are available in two versions: those meant for single-color, and those meant for 5-color LED strip lights. As such, the Centric Home, Centric Daylight, and FilmGrade products utilize single-color connectors, whereas the FiveSpect utilizes the latter option.

If we wanted FilmGrade White or Hybrid Color Tunable, or perhaps even RGB Color Changing so that we can change the color temperature or color, can these strips also be cut and connected in series (including 16 AWG Wire for longer sections between strips) and connected to a single Power Supply and dimmer? Is the TRIAC Dimmable Power Supply and in-line FilmGrade Flicker-Free LED Dimmers the only options here? 

We can confirm that the LED strip lights can be segmented and connected together by the 16 AWG wiring to a single power supply. I can also confirm that third-party dimmable power supplies are likely compatible with our LED strip lights. Please feel free to utilize such a product in your installation.

For the Centric Home or Daylight with an appropriate 3rd part wall dimmer, then I believe my parts list is as follows:

Part 3003.27; or Part 3004.40 (1), PN 3096 (1), Part 3070 (4), Part 3071 (2), Part 7098 (1)

We can further confirm that the parts list provided is compatible! I have attached a link to our LayoutMap below, which illustrates a similar installation that I hope proves to be useful.

LayoutMaps™ - LED Strip Light Layout 3001-1B: https://www.waveformlighting.com/layoutmaps/3001_1B?px=-2071.5&py=-2231.5&pw=1143&ph=1463&s=0.1

Can you tell me if any of the following would be an acceptable alternate parts list to that in Item 3 above? Part 3001.32 (1), Part 3002. HY, or Part 3021.

Will the TRIAC Dimmable Power Supply (PN 3094.096) allow the use of a 3rd Party Wall Dimmer? Or is PN 3092 + DC Adapter PN 7094 + an in-line dimmer required?

We believe that the 3200K FilmGrade White (Part 3001.32) would be a great alternative, as it would allow for the preferred color temperature while also being compatible with the other items in your parts list. The FilmGrade Hybrid and Color Space RGB products are different, in that they would require different connectors and potentially additional controllers for adjusting the light output.

Our products are designed for use with modern phase dimmers, though they are not designed for use with older dimmers such as rheostat dimmers.

Unfortunately, our various strip-to-wire and strip-to-strip products are not compatible with the Hybrid and Color Space products, as the solder pads are located in slightly different places than the other products they are designed to be compatible with.

For the Power Supply, if we are using a modern phase wall dimmer, can we use the Film Grade DC Part 3092 and connect directly to the female DC Jack on the Film Grade strip?

Is it required (or preferable) to use the Centric Series Dimmable Power Supply (24V) TRIAC Dimmable Power Supply (Part 3096) with 1 Part 7095 Male DC Barrel Jack Adapter?

We're happy to confirm that the 3200K FilmGrade product is single-color, and can be used with the PN3070 & PN3071 connectors.

The answer to the second question really depends on your preference. For installations that are not permanent, the DC power supply is a great option. 

However, the DC power supply cannot easily be connected to a wall dimmer. If a wall dimmer is preferred, we recommend the TRIAC Dimmable Power Supply paired with the PN7095 adapter.

I believe this is my required parts list For the 3200K Film Grade White:

Part 3001.32 (1), PN 3096 (1), PN 7095 (1), PN 3070 (4), PN 3071 (3), PN 7098 (1)

Regarding your list, I noticed that the power supply and LED strip lights are of different voltages. I would recommend selecting the matching 12V or 24V voltage products for your installation, depending on the preferred voltage.

The (slightly) updated parts list would be:

PN 3002.32 (1), PN 3104 (1), PN 7095 (1), PN 3070 (4), PN 3071 (3), PN 7098 (1)

LED Dimmer & Power Supply Setup

I have a LED "neon" sign. It came with the following power supply: Input AC100-240V, Output 12 VDC, 4A. I am interested in purchasing your Model #3081 LED dimmer. Can I use my existing power supply or do I need to also order your #3091 power supply? I do not know any specs on the LEDs but they did work with a 9V DC input as well. But did not light at 6V DC.

It's always quite tricky when dealing with third-party products, but based on the power supply specifications, I do believe that there is a good chance that our PN 3081 LED dimmer would indeed be compatible.

​The LED dimmer specifications are 6-60 volts DC and 0-10 amps. The power supply you currently have is well within the bounds of the LED dimmer specifications, so I believe these should all be compatible and you would not need to purchase a separate power supply such as PN 3091.

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

Does your LED dimmer compatible with Meanwell HLG products?

I wondered, can your Flicker-free LED dimmer be used in series with a Mean Well HLG-120H-30A? 

While this specific combination has not been tested, I do believe that our FilmGrade dimmer is compatible with the Meanwell HLG product line.

​Do keep in mind that you may require a wire adapter such as PN 7095 to connect the output end of the Meanwell power supply to the input side of the dimmer.

For any large or permanent installations, we recommend testing to ensure compatibility. If for whatever reason you find that the LED dimmer will not work for your project, we would be more than happy to pay for return shipping and offer a full refund. 

LED Lights and Components for Under-Cabinet and Floating Vanity Lighting

We are currently planning to install under-cabinet lighting under some kitchen cabinets and a floating vanity in our bathroom. Your centric home strip lights have great reviews in terms of color quality. What is all of the components that we would need to buy to have diffused, even lighting that is dimmable? 

We have provided a few links from our website below, which I hope prove to be helpful for your installation planning. Each of these links contains an interactive diagram of the configuration options available for the Centric LED strip lights product. These diagrams also contain layout descriptions and links to each of the recommended accessories.

In order to diffuse the lighting, we might recommend our Aluminum Channel for LED Flex Strip product, which includes a high light transmission diffuser and is available in both flat and cornered options.

Recommended Lights for Recreational Vehicle

I'm living in an RV and want to redo the lighting and would like some directions. It has 7 circular LED lights (probably 4" diameter) prewired for 12VDC. Ideally, I'm looking to mimic the sun, reds at night, oranges in the afternoon, and a lower blue light throughout the day while I'm home and need to supplement natural daylight. Can you recommend what lights would be good for that and if I would need a dimmer or controller? Also, not sure if I can bend the LED strips into a ring shape to use the existing wiring and light fixtures.

Based on the details provided, the closest product match would be our FilmGrade™ HYBRID LED Strip Lights paired with the FilmGrade™ DMX LED Dimmer & Decoder with 5 Channel Output controller product. As the FilmGrade™ HYBRID LED Strip Lights are designed with both the 3200K and 6500K LED’s, the product output can be tuned to achieve any color temperature in between the two.

You might also benefit from an additional programmable controller that can adjust the light output based on the time of day. Unfortunately, we do not have any guides for this type of configuration at the moment.

While we can confirm that the LED strip lights have a bend tolerance, it is unlikely that they would be pliable enough to be installed within a ring shape, as the product does contain sensitive circuitry.

Recommended Power Supply and LED Dimmer to run a 100ft LED Strip

Have 100' run and looking for suggestions on the power supply and dimmer

If you would like to tell us more about the power draw per foot of the LED strip lights currently being used, we would be happy to provide some dimmer and power supply product recommendations.

In the interim, it might also be helpful to know that our LED strip light products have a maximum combined length which is determined by the hardware. For our 12V LED strip light products, this maximum length is 16.4 ft (5 meters).

For the 24V LED Strip Light products, the combined length is 32.8 ft (10 meters). As our LED strip light products cannot support being powered in lengths greater than the above, we would not recommend installations that exceed these lengths.

I was considering using the film grade 5600

To install a 100 ft length of the 5600K FilmGrade™ WHITE LED Strip Lights we would recommend utilizing the 24V version as it can accommodate larger combined lengths than the 12V version.

As previously mentioned, the 24V FilmGrade™ WHITE LED Strip Lights have a maximum combined length of 32.8 ft. This means that a single power supply cannot power any combined length of the product which is longer than 32.8 ft, as the physical hardware and wiring of the LED strip lights are unable to support it.

As our FilmGrade™ DC Power Supply for LED Strip product can output a maximum of 120W, it would not be able to power any LED lengths greater than 16.4 feet. As such, we recommend utilizing a power supply with a higher output such as 240W.

As the dimmers that we sell are installed between the power supply and the product, we would recommend a dedicated FilmGrade™ Flicker-Free LED Dimmer for each connected length.

It might also be helpful to know that this installation could encounter a voltage drop if it utilizes long lengths of wiring to connect the products. To calculate the voltage drop and recommended wiring, you might find value in the voltage drop calculator tool on our website.

The below diagrams feature information regarding the installation of the FilmGrade™ WHITE LED Strip Lights and provide links to the recommended accessories.

Choosing Compatible Flicker-free LED Dimmer

I was reviewing your 24V LED strip lights and I’d like to know if they meet the other criteria on the attached list (text file attached, and also printed below). 

If so, I’d like some assistance choosing a compatible dimmer that will provide flicker-free dimming on the low end down to 0.1 percent. 

Our CENTRC HOME LED strip lights do meet the color requirements provided - i.e. 95 CRI, 2700K, in-stock. Please see below for the product link:

​The product can be dimmed when paired with our dimmable power supply. Please see below for the product link:

​We also maintain a compatible dimmer list, which shows the dimming range (e.g. 0-100%), which can be found below. This should be a good way to confirm the requirement for dimming down to 0.1%.

Installation Configuration for Kitchen Lighting

We are in the middle of a kitchen remodel and need advice. On our current configuration, we have a 3 ft cabinet, then an opening for the microwave, and then a 2 ft cabinet corner followed by a sink and a 2 ft cabinet. I would like a direct wire, dimmable led configuration. We want a continuous bright setup along the countertop and backsplash. With the spaces with the microwave and sink what would be a good choice for us?

Based on the details provided, we might recommend our 3000K CENTRIC HOME™ LED Strip Lights for Home & Residential product for your kitchen installation.

If you would like to install this product utilizing the wall wiring, we would recommend a matching voltage TRIAC Dimmable Power Supply for LED Strip product. When installed within a junction box or wall cavity, this product can be paired with wall switches and dimmers for light control. For mounting the LED strip light product, you might also be interested in our Aluminum Channel for LED Flex Strip product.

Using the measurements provided, it appears that your installation would require about seven feet of LED strip light product. As such, one 16.4 ft (5 meters) reel of the CENTRIC HOME™ product should provide more than enough lighting for your installation.

However, please note that our LED strip light products are not designed to come into contact with water. If your installation runs across the sink backsplash, your installation might encounter enough moisture to cause product failure or create a safety hazard. That being said, many customers have connected similar lighting segments using hidden 16 AWG wiring behind the drywall, safely away from potential hazards.

We have included some links to our layout diagrams below, which we hope prove to be useful for your planning purposes. This link provides a configuration description and includes links to each of the connector accessories. As you can see, the individual segments can be pretty easily connected to a single power supply.

LED Dimmer Dimension and Wiring Length

I recently purchased: 3 x 3001.56 LED strips and 2 x 3093J Power supplies I'm trying to find a single gang wall switch with two rotary knobs. (I for each power supply). Assuming the need for forward phase dimming I'm not finding anything suitable. I'm thinking it might be best to buy a 2 x 3081 flicker-free LED dimmer. Can someone send the dimensions of the dimmers so I can look into building a desktop enclosure? Also, how long are the input/output wiring leads? The LEDs will be installed and used for safety step lighting in a reference-grade color correction theater (post-production). 

While we generally recommend utilizing an in-wall dimmer for installations which includes the TRIAC Dimmable Power Supply, I believe that the FilmGrade™ Flicker-Free LED Dimmer would be compatible if a barrel-jack adapter is installed between the supply and dimmer products.

There may also be third-party dimmers available online that could be utilized for individually controlling the segments of light strips, such as Lutron Caseta products. Though I do not have any specific products to recommend at this time.

We have attached a marked-up image below, which contains the rough dimensions for the FilmGrade™ Flicker-Free LED Dimmer. We can also confirm that the two wires of the product are each 4 ft (1.2 meters) in length.

Are the 24V TRIAC power supply compatible with Lutron Caseta LED dimmers?

I am interested in purchasing LED strip lights to use with the Lutron Caseta LED dimmers in residential kitchens and baths. Are the 24V TRIAC power supply and Centric Home LED strip the best option for this? Or 12V? Or something else? 

Based on our familiarity with the Lutron Caseta system, we are happy to confirm that 12V or 24V installations should be compatible.

As such, it does not appear that the Lutron Caseta system has any limitations regarding one option being preferred over the other. That being said, there might be some voltage considerations depending on the class or circuits used within your home. To that end, we might recommend reaching out to a local electrician for information on the electrical systems utilized within the residence.

Generally speaking, we strongly recommend selecting the compatible voltage for the lights and power supplies within installations. In case they prove to be helpful for your planning purposes, we have attached two blog post links from our website below, which discuss the options in detail.

Advantages of a 24V LED system vs 12V https://www.waveformlighting.com/home-residential/advantages-of-a-24v-led-system-vs-12v

Pros and cons of a 12V LED system https://www.waveformlighting.com/home-residential/12v-led-system

We are happy to confirm that the CENTRIC HOME™ LED Strip Lights for Home & Residential could be a great option for your kitchen lighting. We generally recommend 2700K for living rooms and bedrooms, or 3000K for kitchens and dining areas. 

I am going to place an order for the Centric Home LED and TRIAD power supplies along with some aluminum track and have a couple more questions. What is your expected shipping time for these products and accessories? Would you be able to provide any promo or coupon code for trying this product out?

Based on my review, it appears that both items are available to be shipped without delay. Further, we unfortunately do not have any special promotional pricing available at the moment, and we do apologize for any inconvenience this might cause.

Regarding accessories, you might find value in the below links from our website. These pages contains illustrated, interactive guides that describe the common product layouts and link to the accessories that we recommend for them.

Film Grade LED Panels for Photographic Printing

Film Grade LED Panels for Photographic Printing

I am a professional photographic printmaker and require High CRI High R9 value print view lighting to just prints. I print using 5000K print view lighting but many times also view the print with 3200K lighting which is closer to the gallery and museum lighting. It looks like your Film Grade 9.5" x 18.9" flexible LED dimmable panel would work well for my needs. My print viewing area is 36" high by 60" wide. I want to determine if I need 1 Film Grade Flexible panel or 2 Film Grade Flexible panels to cover my print viewing area with even illumination. I will also want to be able to select 5000K precisely using the dimmer device. 

Our FilmGrade LED panels would certainly meet your color point needs, but unfortunately, we currently do not have any dimming solutions that would meet your requirements. (We currently support DMX only, for use in TV studio / theatrical installations).

​We do apologize for the inconvenience!

​As an alternative, we would perhaps build a panel using our single-color LED strip lights which can be used with our in-line dimmer. For example, please see below for an example layout:

https://www.waveformlighting.com/layoutmaps/3002_3E

Color Critical Lighting for Cultural Heritage Field

I would like to know if you have a product using the Toshiba TRI-R LEDs. We are involved in the Cultural Heritage field and need a better solution for lighting than currently available products. I am looking for a lighting solution similar to your flexible panels with the lighting spectral quality of the TRI-R-led specifications for proof of product assembly. 

We are not affiliated with Toshiba but we do have a line of 99 CRI products that may closely approximate the color rendition performance you are looking for.

​Below is our product page showcasing our ABSOLUTE SERIES 99 CRI products - please let us know if this is something that may work for your needs, and we would be more than happy to assist with any additional questions or concerns!

https://www.waveformlighting.com/absolute-series

From your link, I think we would need the equivalent of 52 strips to make 2 panels approximately 22”x 11” with full coverage over the area. Is there a connector solution that would work for that? Or do you have an option for the absolute series in an already-made panel about that size?

I would also need a power supply/driver to power 2 panels about that size. As well as a dimming module to work with to set output.

​Unfortunately, we do not have any panel-type products, although I completely agree that this would be an ideal use case for such a product.

​As such, the best alternative would be to use an array of LED strip lights as you suggest. In back-calculating from the suggested quantity, it appears that you would be looking at 26 rows of 22-inch length LED strip sections per panel.

This works out to approximately 48 feet or three reels of 16.4 feet each.

The general limitation for LED strip wiring is 16.4 feet (one reel) per power supply and dimmer connection. This is due to the current carrying capacity limitations in the LED strip as well as those of the power supply.

​As such, your single panel will require three separate sets of power supplies and dimmers, which may or may not be an issue for you from a feasibility perspective.

Each LED strip reel can be cut into as many shorter sections as needed; so each 16.4 ft reel, for example, can be cut into 9 separate sections of 22 inches each, and then re-joined using our solderless connector accessory PN 3071.

(For a visual overview of the components, here is an example layout for a similar configuration using our 24 volt / 95 CRI product which operates nearly identically from an electrical perspective: https://www.waveformlighting.com/layoutmaps/3002_3E)

LED Lights in Overhead Soffit to Reflect Off the Ceiling

I generally sit in that recliner at the far end to read. Want to put sufficient light in the overhead soffit to reflect off the ceiling and illuminate the read. The table lamp shown is decorative the task light, barely visible by the chair, is what I use now. Has an LED bulb in it. Glares for the wife seated on the couch. It works well if I bring it down close to the read (magazine or newspaper) bulb is white.

It sounds like we have a few lighting fixtures in your space. To start, are you able to confirm what type of lamps or bulbs your fixtures can accommodate?

​For example, the soffit looks like it may accommodate fluorescent fixtures, but it's a bit difficult to tell from the photo.

​Similarly, are the table lamp and task light standard fixtures that use medium-screw Edison bases (E26)? (E26 is the most commonly seen, traditional screw-in lamp type with a base that is approximately 1 inch in diameter).

Once you can let us know what types of lamps may be compatible with your existing fixtures, we'll have a better idea of what options we have available for you. 

​Additionally, can you let us know what challenges you're facing with your existing lighting - is it the color, clarity, brightness, or a combination of these factors?

​The soffit has a string of incandescent mini lights, circa 1992. We do not use the table lamp but it and the task light use standard e26 screw-in bulbs, the problem is insufficient illumination. The task light if I bring it close to the reading material will work but is ungainly and if it is set higher is not quite enough light but glares at anyone sitting on the couch. I had thought that linear LEDs in both soffits above the chair reflecting off the ceiling might work but leave that to your expertise. Using dimmers they could also provide illumination for the room. The soffit runs on three sides of the room.

We are in full agreement that improving the brightness from your soffit lighting fixture would be the best approach here to simultaneously increase brightness without causing additional glare issues.

​Unfortunately, despite their ubiquity, standard light bulbs induce significant amounts of glare due to their high brightness levels from a relatively small size.

Our first thought here would be to recommend our CENTRIC HOME LED strip lights in 3000K. These LED strip lights emit approximately 450 lumens per foot, which is approximately equal in brightness to a 40-watt incandescent bulb. 

It's a bit difficult to determine from your photo, but my best guess would be that your soffit is approximately 10 feet long. If you were to install the LED strip lights across the entire soffit, this would provide you with approximately 4500 lumens, or 400 watts worth of incandescent bulb brightness.

The LED strip lights could of course extend and span multiple soffits across the three sides of the room as you suggest.

The LED strip lights do require some in-wall wiring and assembly work, but I do believe that this would be an excellent option for you. Below is an example wiring diagram that shows how the LED strips can be wired to a wall dimmer:

https://www.waveformlighting.com/layoutmaps/3001_1A

Sometimes sitting on the end of the couch to utilize the halogen Torch which almost does the job but could be better. The new light needs to be dimmable, and maybe the color change? 

Each one of the curtains is approx 6 ft across giving us approx 12 ft of the strip light. Approx 5500 lumens per your calculations. You mentioned 3000 Kelvin. Is that overly yellow for reading? Are your strip lights disabled and what dimmer do you suggest for the best performance? 

Is there an approved dimmer for 3-circuit control? I note that LeGrand makes a couple although I am partial to Lutron. 

I personally do not believe that 3000K is "too yellow" although that would certainly be within the realm of personal preference. Do you know what the color temperature of the lamps in your current space is, and what your thoughts on those might be? (Incandescent bulbs are typically 2700K and lower).

To cover the distances you quoted, you will likely need three sets of 16.4 ft LED strip reels, each with its own dimmable power supply. The cost estimate is as follows:

CENTRIC HOME™ LED Strip Lights for Home & Residential: $99 ea

TRIAC Dimmable Power Supply for LED Strip: $139 ea

​We do not have any three-circuit control suggestions, but we do have a list of tested dimmers which are available here:

https://www.waveformlighting.com/files/DC_3093.pdf

The reading lamp has a 790-lumen GE REVEAL built therein. It is I think overly bright white. If I bring it clues to the reading material it works but is glary with poor contrast and if further away not bright enough but not heavy. The soffit has a string of very old very small incandescent. I think we might try one set in the two soffits over the Chair to see how this indirect lighting works. 

We believe the GE Reveal lamps use a modified 3000K spectrum. If you find the incandescent lights in the soffit to be acceptable from a color perspective (i.e. not too yellow), then 2700K could also be a good option for you.

Below is an article that might help choose between the two options:

LED Strips for Space Lighting Upgrade

I'm trying to decide what I need to set up your product in my space. Currently, I have fluorescent tubes in a 500 ft. workspace. I would like to replace these with your 99 CRI LED strips and hardwire them to my existing wiring and use a dimmer. I'm not sure if I need 12 or 24, or if I need the Junction box on my power source. 

Our 99 CRI ABSOLUTE SERIES sounds like a great option for upgrading your space's lighting! The flexible LED strip version is available in 12 volts only, so you will want to use the 12 volt TRIAC dimmable power supply to power the LED strip.

​Below is the direct link to the dimmable power supply:

If you intend to install the power supply unit directly inside the fixture, I do not believe that there will be a need for the junction box; typically the junction box is used when the power supply is mounted in an interior wall location.

If you are comfortable with and able to solder your own wires, that would perhaps provide you with the most flexibility and cleanest wiring installation, however, if not, our PN 3070 and PN 3071 connectors may be convenient options for you.

I am replacing five T12 tubes in this space (2500 lumens each), and it seems to be about 60% as bright, even though the lumens should be very close. 

The strip that is wired to the power source is brighter than the second strip, which is wired to the first strip. 

The brighter strip also seems very noticeably brighter closer to the connection that goes to the power source. The channel is also quite hot close to the connection, and warm at the other end. The second strip channel is not warm. 

The brightness drop you are observing may be caused by voltage drop, which can occur during longer LED strip installations. Can you provide some additional detail on how the two LED strip reels are connected?

For voltage drop and safety reasons, the maximum run length specification for any LED strip section is 16.4 ft. Therefore, if you are attempting to connect multiple reels to a single LED power supply, this would likely cause the voltage drop and reduction in brightness you are observing in the second reel.

​As such, we generally recommend connecting each 16.4 ft reel to a separate power supply unit to ensure that the maximum run length is not exceeded.

Can you point me to where in your documentation you recommend using a separate power supply for each 16 ft strip? 

Please see below for the datasheet which indicates the "max run" specification of 16.4 ft.

​https://www.waveformlighting.com/datasheets/CS_7101.pdf

How much LED Lights are needed for Office Lighting

I have a 12x12 home office. I’m wanting to run your LED lights (power supply, connectors) around the perimeter of the office, but I’m unsure of how many complete systems (LED lights, power supplies, connectors, etc) I need to order. From what I see the strips come in 16’ sections, and if I need to go around the entire perimeter I’d need 3, of your complete systems, but I need to how bright the three systems would be would it be better to split one or two up? The LED lights need to be dimmable. 

I've plugged the 12 x 12 foot dimensions into our lumen estimation calculator (https://www.waveformlighting.com/lumen-calculator), which suggests a total brightness of 5850 lumens for an office space (approximately 40 footcandles).

​Our LED strip lights emit 450 lumens per foot, so 14 feet would be sufficient (just short of 1 reel) to meet this brightness level.

If you plan on installing a dimmer, however, there is no such thing as being "too bright" since this can always be dialed down if needed, and having the LED strip lights installed along the entire perimeter of your office space on each side might be a nice way to provide even and well distributed lighting.

One more thing, just so I understand what I need to do to get this operational, could you please provide me with a simple diagram from power in to the LED the entire diagram of this project. Would you suggest breaking the 16' strip into 4 equal parts or even 8 equal parts and place around the perimeter. Also, can you tell me how soon you can ship once we know exactly what is needed?

Below is a simplified wiring diagram showing two 16-ft reel circuits connected to a single dimmer. In your setup, you will want to replicate this a third time for the third circuit.

​https://www.waveformlighting.com/layoutmaps/3001_1C

​I would recommend installing the LED strips as three equal parts at 16 ft each. The reason is that if we do four equal parts (or more), that would potentially require installing four separate power supplies (or more) as each power supply is limited to powering a maximum of 16.4 ft for any given connection.

​Given the dimensions of your space, turning the corners at each 12 ft mark may be a bit of a challenge depending on the configuration of your interior. An additional diagram link below shows how the LED strip sections can be cut into shorter segments and rejoined using our various accessory items. I suspect that PN 3071 may be helpful for you when turning the corners of space.

​https://www.waveformlighting.com/layoutmaps/3001_1B

​Below is an preliminary shopping cart I've put together for you which includes the three sets of LED strip reels and corresponding power supplies. I've also included a 10-pack of the aforementioned PN 3071 accessory.

https://store.waveformlighting.com/27932316/invoices/96f20fd5f0df2415844ff452f475d2dd

​Our order turnaround time is typically 1-2 business days, and we do offer complimentary standard shipping which is typically delivered within a 5-10 business day timeframe. We also offer expedited shipping options for an additional charge; expedited shipping times and costs are calculated at checkout, but I would be more than happy to assist in calculating those for you if you can confirm your shipping address and cart contents.

Are the ABSOLUTE SERIES™ LED Flexible Strip 5000k version flicker-free?

Are the 5000k version of this series flicker-free?

We are happy to confirm that the 5000K ABSOLUTE SERIES™ LED Flexible Strip operates with flicker-free performance when paired with a power supply such as our 12V FilmGrade™ DC Power Supply for LED Strip.

As can be noted on the Photometric Data sheet for the product, the flicker percentage when tested with the FilmGrade™ DC Power Supply for LED Strip is 0.01%.

Are the grounds on the in/outs of the LED dimmer isolated or coupled?

I just placed an order for a large lighting array I'm building, including 18 dimmers. I'm hoping to get electrical details of the dimmers, to hopefully make the wiring as efficient as possible. Are the grounds on the in/outs isolated or coupled? I'm hoping they're coupled, so I can combine some of the ground wirings and bypass the dimmer on the return wiring from the LED strips. 

I don't have the schematic for the product on hand, but I do not believe that the input and output ground are coupled, so you will likely need to wire the LED strip ground back through the same dimmer's output ground.

​

Layout Design for Tape Light Installation

If I provide you with a sketch of my planned tape light installation, can you provide information regarding the appropriate transformer and all other parts? 

​In the meantime, I've linked to our layout maps page which shows several sample installation configurations and may be a helpful starting point for you:

​https://www.waveformlighting.com/layoutmaps

Attached is a draft of my layout. I plan on hard-wiring the power supply to a wall dimmer switch. I'm sure you will have questions. If you do let me know.

​Your layout looks great, and I do not see any issues apart from a potential power capacity limitation.

​From your drawing, I see five sections of 46 inches each. If I've done the math correctly, this works out to approximately 19.2 ft in total.

​Each foot of our LED strip light draws approximately 5.5 watts. This equates to a power capacity requirement of approximately 106 watts.

The drawing does not indicate the voltage (12 or 24 volts), but this will likely determine what is permissible here. While the 12-volt version of our TRIAC dimmable power supply will be able to support up to 120 watts per connection, our 24-volt version is limited to 96 watts. As such, the 12-volt version would be the only way to connect the entire circuit to a single power supply.

The only downside to the 12-volt version is greater susceptibility to voltage drop and the fact that the circuit would not comply with NEC Class 2 power limitations, making electrical code compliance potentially a bit more challenging (if that is a concern).

Based on the LED length per segment being less than 4 feet and the feeds being relatively short (max 72 inches) I do not foresee any voltage drop issues even with the 12-volt version.

Finally, we do not have any in-house products/adapters to join all five segments near the power supply, so you may need to create your wire junction or utilize third-party products for this connection point.

Please elaborate on what you meant by the fact that the circuit would not meet NEC Class 2 power limitations making the electric code compliance potentially a bit more challenging.

Would this cause a problem with house inspections, hard wire connections to a wall dimmer, etc?

If so, how could the design be changed?

When it comes to building inspections (typically subject to NEC standards), our LED strip lights themselves are rated for use in Class 2 circuits only. As such, the use of our LED strips on a Class 1 circuit would technically be a violation of the NEC rules and regulations. We would therefore recommend staying with a Class 2 installation.

At a basic level, our 24-volt TRIAC dimmable power supply (96-watt capacity) is a Class 2 power supply that can power up to 16.4 ft of LED strip lights. As such, as per my calculations, you would be able to connect up to four segments of 46" each, as that would total 15.3 ft, which would be below the 16.4 ft limit.

Can I purchase a separate power supplies with dimmers to connect the cut LED strips?

I'm excited about your products and I want to purchase FilmGrade™ WHITE LED Strip Lights. I need a 16ft LED strip but I need to cut it into small pieces, and separately control the lights by dimming them. Can I purchase separate power supplies with dimmers, so I can connect the parts that I cut? 

We are happy to confirm that the LED strip light segments can be individually powered and connected with dimmer products. 

Below are some product configurations from our website, which could be useful for your planning purposes.

Are the FilmGrade White LED Strip Lights dimmable?

I just ordered film grade white led strip lights 5600K and 3200K. My question is are these dimmable? 

Yes, our FilmGrade LED strip lights are indeed dimmable when connected to a dimmer. Please see below for an example layout:

https://www.waveformlighting.com/layoutmaps/3002_3D

Here is a direct link to the dimmer product:

What I was looking for was a Hybrid version that had both 3200K and 5600K LEDs on the same strip. Do you have anything along those lines?

The closest option we currently have would be our hybrid LED strip at 3200K/6500K - please see below and let me know if this will work for your needs.

The controller setup will be a bit difficult without a dedicated DMX control system, however, so if you do not have that we would perhaps recommend staying with the two separate LED strip reels controlled individually.

LED Dimmer and Installation Questions

I am installing the CENTRIC HOME™ 3000K / 12V DC with a TRIAC Dimmable Power Supply. Can you suggest the best dimmer to use? In terms of this installation, I plan to reuse the existing wiring from my old under-cabinet fixtures. I think that I may need to attach leads to the old wiring so that the wire is stepped down to a size small enough to solder on the LED strips - any advice/tips/tricks for a neat(er) install? This install will have 7 discrete lamp sections ranging from 8" to 32" in length - altogether it's under 12' - all lamps will be housed inside the channel that I purchased from you too. Is the power supply I selected capable of driving this load? Lastly, the track comes with 5 end cap pairs - can you provide an additional 5 pairs so that I have a few extra for the installation? 

First of all, with respect to dimmer compatibility, our TRIAC dimmable power supplies are designed to work with virtually all phase dimmers so you should not have any significant issues with compatibility.

That being said, below is a list of the dimmers we have tested and their dimming range results:

https://www.waveformlighting.com/files/DC_3093.pdf

We do see that the Lutron DVCL series is a popular choice among our customers and we have not received any reports of flickering or other compatibility issues.

Second, for soldering, I do not believe there should be any significant challenges regardless of the incoming wire type or size. Since the solder pads are quite large, they should take solder quite readily without any issues.

One recommendation, however, would be to consider using our PN 3070 solderless connectors. The two wire ends can be joined together using standard twist-on wire connectors (aka "wire nuts")

As long as the total connection length is at 16.4 feet or less (you mentioned 12 feet), you will be fine with the single power supply unit.

We, unfortunately, do not have any additional mounting hardware on hand for the aluminum channels, but I'll be more than happy to see if we have any extras available to send to you!

I’d prefer solderless connectors but I think I read in your literature that they don’t fit inside the tracks. can you clarify this - or perhaps send a photo of an install so I can plan for it?

You are correct that the solderless connectors are too wide for the aluminum channels, unfortunately. I'm sorry for the oversight here as I had not realized that the LEDs would be installed in the aluminum channels (I should have reviewed your order in greater detail!)

​The "workaround" would be to have the LED strip protrude from the end of the aluminum channel by about half an inch, thereby allowing the connector part of the solderless connector to connect outside of the aluminum channel. I would imagine that this would not be ideal from an aesthetics perspective in most cases, but at a practical level, this would technically work.

Otherwise, the alternative solution would be soldering the wires directly onto the copper pads, as was originally proposed.

Dimmable Power Supply Compatible with Centric Home LED Strip Lights

I'm building a light fixture for my dining room, which is roughly 10' x 10' x 15' high (it's an open space). I've calculated that I need 1,673 lumens and that 3' of your CENTRIC HOME™ LED Strip Lights for Home & Residential will provide that. What dimmable power supply do I need (assuming I use a Lutron or Leviton wall dimmer)? 

You are correct that the 3-foot section will provide approximately 1650 lumens, which should be sufficient for your needs. Do keep in mind, however, that depending on the design of your fixture, you may want a bit more brightness depending on the orientation of the LED strip lights as well as the fixture.

​As far as connecting the LED strip lights to a dimmer switch, you will want to use our TRIAC dimmable power supply product. we've included the product link below for your reference.

Additionally, our layout map for the product may be helpful in understanding how the product can be wired to your dimmer circuit: 

https://www.waveformlighting.com/layoutmaps/3001_1A

Can you specify one or two specific Leviton or Lutron wall dimmer switches that are compatible with my order? 

We've tested a wide range of Lutron and Leviton wall dimmers for compatibility. Some of the most popular include the Lutron DVCL-153 series, which we have linked to below:

How do you change the colors on the RGB LED Light Strip?

The color space RGB color changing LED strip because I don’t know if you provide a remote or use an in-app controller

We're happy to confirm that the ColorSpace™ RGB Color Changing LED Strip Lights product can be controlled using several third-party apps and Bluetooth controller systems, such as the Lutron Caseta system.

However, we, unfortunately, do not have any guides which describe these configurations in detail available at this time.

Is it best to be using the 95 CRI products for Art Lighting?

We are wrapping up a project with an art wall for a special piece of art and need to light it with even light intensity and would like to learn more about your products. 

To light art, it is best to be using your 95 CRI products right?

Yes, the higher the CRI, the better the appearance of the colors in your artwork.

What is the difference between a Centric Home 3000K strip (3003.27) vs. a film grade 3200K tungsten strip (3001.32)?

The primary difference between the CENTRIC HOME and FilmGrade LED strip lights is the color temperature. The former is offered in 3000K, compared to the latter, which is offered in 3200K. The CENTRIC HOME at 3000K will be a closer match to halogen lighting used in art galleries, whereas the FilmGrade at 3200K is closer to tungsten lighting used in TV and movie sets.

It would seem all the strips have a max light intensity of 450 lumens per foot, are there higher lumen strips in the 3000K - 3200K color temp range?

Unfortunately we do not have any brighter LED strips. If more light is needed, we would recommend "doubling up" the number of rows.

How much lumen can be expected to be lost if used behind the lens of the corner aluminum channel?

We generally observe light loss of 10-15% when the diffuser cover is applied over the LED strip light.

Safe to assume all the strips are dimmable?

Yes, all LED strip lights are dimmable as long as they are connected to a dimmable power supply unit. (See below)

For about 13.5’ of stip lighting, what’s the best power supply to get and do you guys offer a hard wire remote transformer product to power the lights?

Please see below for the product link for our dimmable power supply which can be hard-wired to a dimmer circuit. One popular solution for controlling this power supply is using the Lutron Caseta dimmer system.

Below is some additional guidance on using the Lutron Caseta system with our LED strip lights:

For dimming of the light strip, what’s the best wall mount switch type dimmer to get that won’t cause flicker?

As long as you use our dimmable power supplies, you will be able to achieve flicker-free output regardless of the wall dimmer model or manufacturer.

LED Strip Lights for Photographing Artworks

I'm looking to create a lighting setup for digitally photographing artworks (mainly paintings) and then printing the files. 

I intended to make 4 panels around 40x50cm from 2-3 5m led rolls cut to lengths and attached to a backboard. I would like to be able to dim these panels also.

​This sounds like a great approach and excellent use case for the ABSOLUTE SERIES LED strip lights. The LED strip lights include double-sided adhesive and should allow for quick installation onto the backboard.

​For dimming, we recommend our FilmGrade flicker-free LED dimmer, which can be installed in between the LED strip lights and the power supply. Please see below for the product link:

​I am looking at the 99% absolute series and would like advice on how much light I may need (how close to space led strips on the panels?) and which driver I may need for say 7.5-meter strip cut to lengths.

​The amount of light needed would depend on the brightness needed for your photography (perhaps determined by your shutter speed, aperture, and ISO settings) as well as the distance away from the artwork. As a general ballpark estimate, each meter emits approximately 1250 lumens, which is equivalent to a 75-100 watt incandescent bulb.

​The maximum run length for the product is 5.0 meters. If connecting 7.5 meters per panel, you will need two separate power supplies (and perhaps, unfortunately, you will also require two separate dimmers for the separate circuits). The link to the power supply is shown below:

​Our general recommendation for spacing is to space the LED strip lights no farther apart than the distance from the illumination surface. In other words, if the panel is to be placed 20 cm from the illumination surface, the LED strips should not be spaced farther than 20 cm apart.

​Also, would the absolute series be good to record digital colors from paintings? I may install a linear polarizing sheet across the front of the panels also. They will likely be set at 45 degrees to paint.

​Yes, the ABSOLUTE SERIES is a great option for digital image capture! The 99 CRI rating is the highest that is currently available in the industry and informs us that the color accuracy as captured by your camera would be nearly perfect.

​The polarizing sheet, as well as perhaps a diffuser sheet, can help ensure even and smooth light distribution across the paintings.

​I notice a beam angle referenced in preassembled lighting panels - can you briefly explain this? and is it possible to recreate it with the strip LEDs?

The beam angle refers to the angle at which the light is dispersed. Our LED strip lights have a beam angle of 120 degrees, which you can think of as being a very wide conical light dispersion angle.

An led strip shows a lumen output of 6250. What would be a comparison in Lux at 1m or 3m? I suspect I am a little underpowered at 6250 lumens / 416 watts approx.

​A single row of LED strip lights will provide approximately 300 lux at 1 meter, and 25 lux at 3 meters. If using multiple rows, however, you would be able to add these lux values up in a linear fashion to determine the illuminance on that particular surface.

​You mentioned a space of 20cm between strips at a 20cm distance. I had guessed placing led strips at around an 8cm gap (mainly for estimated panel size using a 1x 5m reel, but I think I may need the strips much closer. 

Closer together than the 20 cm distance I had somewhat arbitrarily suggested is not an issue at all.

​I think I may need 4 panels of 5m strips cut to lengths (with a driver and dimmer for each panel) although this becomes pricy. Would you concur that with your products a 5m strip is the maximum for the drivers and dimmer?

Unfortunately, the maximum run length would indeed be 5 meters due to the power supply capacity as well as the limitations of the LED strip circuitry.

I generally understand CRI and the wavelengths of color and your absolute series seems to be as good as a "roto light" or "Gemini lite panel" and possibly as good as it gets. I see another figure being used for color perception and described as TICI. Do you have a rating for the Absolute series and what is TICI? (can't find it on google)

TLCI is the Television Lighting Consistency Index, frequently used in TV and broadcast environments in Europe. Similar to CRI, the TLCI determines color accuracy in the context of cameras and photography. Our ABSOLUTE SERIES has been tested to 99 TLCI (please see attached).

Are your LEDs flicker-free? I presume 4x 5m reels could all be exactly the same intensity and color? And the best color accuracy would be from a fixed-temperature LED. I note the preassembled panels from others have control over temperature, intensity, and hue in some cases.

Our LEDs are flicker-free when used with a flicker-free power source. All reels are calibrated to the same brightness and color point and are not adjustable, unfortunately.

​Would you happen to know what the import charges would be?

Unfortunately, import charges are quite variable and it is difficult to provide estimates up front, as these can depend on the specific port of import as well as customs officer discretion.

​If you would like to inquire with local customs authorities in advance, you might want to check on the estimated costs for products with HTS code 8539.50.0090, which is what is typically used for LED strip lights.

Compatible Dimmer & Power Supply for 24V LED Strip Lights

I am putting an order together for two of your 5m 24v 4000k 95 CRI LED light strips and need your help choosing a MeanWell 24V 150W Power Supply to drive an 18.5-foot segment. I am considering the MeanWell ELG-150-24AB and Lutron Caseta Wireless ELV. Will this work with these strips? Is there a better 150W power supply?

We've reviewed the product literature for the Meanwell product model numbers supplied, and all of them appear to be compatible with an 18-ft installation of our CENTRIC DAYLIGHT 24-volt 4000K LED strip lights. The primary electrical requirements for this installation would be 24 volts DC constant voltage output and a power capacity of at least 120 watts (5.5 watts x 18 ft = 99 watts, 20% overhead added).

​All three of the Meanwell products you mentioned appear to have the ability to provide this output, so they should be compatible; for further differences and recommendations between those options, we would recommend reaching out to Meanwell to better determine the best fit.

We did notice that you're looking to use a Lutron Caseta dimmer, which uses a phase-cut dimming signal. From what we understand, Meanwell products are NOT compatible with phase-cut dimmers and therefore may present some compatibility issues, so we would recommend reviewing this as well.

Choosing between T8 LED Tube and LED Strips for an Existing Electrical Boxes

I'm trying to choose between tube and strip lights and I need info on how I can hook it into my existing ceiling outlet box. 

While each installation can differ, we generally recommend using our LED tube lights if there is an existing 4-ft fixture already in place. Our LED tube lights can be used without a ballast and therefore can be used without any additional electronic components.

LED strip lights, on the other hand, can provide you with some additional versatility and installation options. This approach, however, will require additional wiring and configuration, including power supply units and LED strip assembly.

I have six separate track lights on separate dimmer switches. The reasons they interest me are that they look to be very low profile and you have a 99 CRI strip light but only 95 CRI tube lights. Are there any other advantages or disadvantages I should be aware of for strips vs ubes? If I go with the strip light option, what do I need to do? How does it connect to the end feed and will the extra transformer fit inside the end feed? Will I need new dimmer switches? I currently use these(Lutron CTELV-303P-WH Skylark Contour 300W Electronic Low Voltage Single Pole / 3-Way).

Since you don't have a fluorescent fixture at all, the LED strip light option is definitely worth considering.

The challenge with installing an LED strip light in a location like this is that the existing track systems operate at a completely different voltage type and level. Typically, they are 120 volts or 12 volts AC, while the LED strip lights require 12 volts DC.

As such, the electrical wiring and systems inside the track lights will not be useful here and will need to be bypassed completely.

Below is a configuration diagram for a simple LED strip setup:

https://www.waveformlighting.com/layoutmaps/3001_1A

You will see the TRIAC dimmable power supply, which is the key component here that you will want to determine where you can fit this in your current installation. It is a somewhat bulky device and you will want to ensure it is installed in a location compliant to local electrical code. (Most frequently, it is installed inside of a junction box mounted inside of the wall).

The TRIAC power supply appears to be 9 inches, so it won't fit in the current electrical box in the ceiling. Could I just purchase your junction box and attach it to the ceiling? Do you sell it in white? Alternatively, I could install the TRIAC in the attic near the switches, but then it would need to feed into the current wires that run to the ceiling position. I'm thinking that those standard wires must be different than the ones needed for the DC, is that right? If so, I guess the TRIAC has to go right next to the strip lights. 

We are not sure about the electrical code requirements and considerations of mounting the junction box on the ceiling, so that is something you will want to confirm before going down that path. The junction box is unfortunately not available in any other colors.

The concern with installing the TRIAC dimmable power supply far from the LED strip lights is that large distances between the power supply and LED strip lights can result in voltage drop, whereby the brightness of the LED strips become diminished by the reduction in voltage supply. Generally, we recommend keeping the LED strip sections within 32 feet of the power supply unit to reduce the impact of voltage drop.

My understanding is that your tube lights are not dimmable, is that correct? 

That is correct. We agree that the LED strips would be the best option for a dimmable + flicker-free lighting solution.

​Do you sell L pieces for the aluminum channel so I can turn corners with the flex strips?

Unfortunately we do not sell any "L" shaped corner pieces. The best way to accomplish this would be to solder wires directly between the LED strip segments that meet at the corner. The aluminum channels can also be cut at 45-degree angles to create a gapless 90-degree turn.

​Do I need the centric series power supply rather than the triac to get flicker free? 

​The most recent batch of TRIAC dimmable power supplies is also now rated flicker-free. Therefore, you will be able to use the TRIAC dimmable power supply and achieve flicker-free and dimmable light output.

​Do you sell a junction box that covers the centric? 

​We do not sell a junction box for the CENTRIC SERIES power supply. We would recommend going with the TRIAC dimmable power supply since it also provides flicker-free light output.

Can I connect two separate 8 foot strips to one power supply? 

Yes, they can be connected "in parallel" - please see the blog post below:

https://www.waveformlighting.com/home-residential/connecting-led-strips-in-series-vs-parallel

I'm just about ready to order the absolute strip. I'm still trying to decide on whether to go with 6500k or 5000k. What connector will I need for that? 

Both the 5000K and 6500K should be good options for you. Here is an article, in case you haven't had a chance to yet see it, that might help you make a more informed decision one way or another:

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

Once the LED strip is cut, it cannot be re-joined using the pre-mounted female DC cables. They can be re-joined using the PN 3071 accessory that you have correctly identified.

Does High CRI LED Strip Light Flicker-free?

Does high CRI LED strip flicker-free? In that, if we use the dimmer, it will be flicker-free or not? We need to use your LEDs for our test equipment and we need to control the lux level with your diffuser, will it be recommended that any other products be available with you? 

We're happy to confirm that our LED Strip Lights are flicker-free when paired with a flicker-free power supply, such as our FilmGrade™ DC Power Supply for LED Strip, as well as our FilmGrade™ Flicker-Free LED Dimmer.

Please note that as our LED Strip Light products are available in both 12V and 24V versions, it will be important to select a compatible 12V or 24V power supply. 

LED Strip Lighting Layout

I am only putting the best into this place, so that means quality lighting. I am in a 19 x 16' space with 10' high ceilings and am curious as to what layout would be best. I plan on installing both the 4000k LED strip lighting alongside the red LED strip lighting for nighttime sessions. I will likely have both on during the day to put some Red back into the spectrum. When I install them, what is the recommended spacing between the two? Or have them right next to each other? I want what looks best and most balanced. 

Based on the measurements provided, we calculate that the space would be sufficiently illuminated by 14,960 lumens. As such, we might recommend utilizing 34 feet of LED Strip Lights in your studio space, which is just about two 16.4 ft reels of the LED strip lighting products, which emit 450 lumens per foot.

It might also be helpful to know that our 12V and 24V LED strip light products have maximum run lengths that can be powered by a single power supply. The maximum length for 12V is 16.4 ft, whereas the 24V maximum length is 32.8 ft.

As such, depending on the product selected, you will require a dedicated power supply of the matching product voltage. Further, each dedicated length and power supply will require a dedicated dimmer unit, in the event that you would like to dim the connected lengths of strip light products.

​We have attached a link below, which illustrates a common LED strip light configuration that utilizes multiple connected segments.

LayoutMaps™ - LED Strip Light Layout 3001-1B: https://www.waveformlighting.com/layoutmaps/3001_1B?px=-2201.5&py=-2227.5&pw=1403&ph=1455&s=0.1

Regarding light configuration, you may find that the ideal distance between the red and 4000K white LED strip lights may come down to personal preference and layout. As such, there is unfortunately not a precise alignment recommendation that we could make.

That being said, it might be helpful to know that many customers choose to install these lights along the ceiling perimeter to wash the walls in light.

While these LED strip lights can be installed in multiple ways, we also sell the Aluminum Channel for LED Flex Strip product which can be used for mounting the lights within corners or flat surfaces.

Can the power supplies/drivers be remotely mounted?

My question is regarding both dimmable and non-dimmable drivers for Waveform’s strip lights. Can these be remotely mounted? How far can the driver be from the light strip (Film Grade 5600k)? I will need 4 drivers for my installation. How much space is required between drivers?

The difficulty with the remote mounting of the LED strip power supplies is that they operate on low voltage DC, so we do want to be careful about the distance between the power supply and the LED strip light, as they can be susceptible to voltage drop.

​While we do not have an official specification, our recommendation would be to keep the distance between the power supply and the LED strip run to within 32 feet, as this will keep voltage drop to within 0.5 volts. This assumes that the system uses 24-volt DC and 16 AWG wires.

In terms of spacing, the LED power supplies should be provided with ample space around the units to provide sufficient ventilation and cooling. For additional reliability and safety, we would recommend using the junction box accessory.

LED Strip, Power and Control for Under Cabinet Lighting

I wanted a tunable light under the cabinet. My preference would be if could dim the lights at the switch, but control the "color" of the light with an app. Is this possible? We have three individual cabinet areas: 1) 80" span with a 30" gap over the stop and then continues for another 18" (we would not need to light under the stove) 2) 52" span (nothing special here) 3) 74" counter span (nothing special here, either) What products do we need to accomplish this? 

Our FilmGrade Hybrid LED strip lights are designed for cinematography applications, but they could certainly be repurposed for an under-cabinet installation.

A very nice feature of the FilmGrade Hybrid LED strip lights is the ability to change the color temperature of the lights between 3200K (warm white) and 6500K (cool white). This will, however, require some additional third-party controllers to achieve, and would not be compatible with a wall-dimmer installation.

For under-cabinet installations, most of our customers utilize a single-color LED strip light installation using our CENTRIC HOME LED strip lights. While this product is fixed at a single color temperature, this product may be better suited for an under-cabinet installation as the color temperature options of 2700K or 3000K are better suited for residential installations. Additionally, it can be hard-wired to a wall switch, and also includes UL safety ratings for permanent residential installations.

Below is a link to an example installation diagram along with a parts list, which you may find helpful:

https://www.waveformlighting.com/layoutmaps/3001_1A

Based on the cabinet dimensions we have approximately 18' linear feet of cabinets in three unique areas that will need lighting. Do we need three reels and three power supplies or could we do two reels and three power supplies?

The LED strip reels can be cut into shorter lengths, so the two reels with three power supplies sound like a better option for you!

​The two reels will provide you with sufficient length to cover 32.8 ft, which is more than the 18 feet required for your cabinet dimensions.

​In fact, a single reel will provide you with 16.4 ft, so if you are OK with shortening the LED strip lights for some of your cabinets (the LED strip lights most likely do not need to go all the way from one end of the cabinet to the other), that might also save some of your cost as you would be able to use just a single reel instead of two.

Here is an example layout diagram that you may find helpful:

https://www.waveformlighting.com/layoutmaps/3001_1B

We're not sure if we need the 12V or 24V, and also do we need a junction box with the power supply?

I also want to confirm our dimmer switches will be compatible with this. Below are two different dimmer switches I'm planning to purchase:

Lutron MACL-153M-TP Maestro

Lutron MRF2-10D-120-TP Maestro 

Both the 12-volt and 24-volt versions will work OK for your installation, but generally, we recommend our 24-volt versions as they perform slightly more efficiently than their 12-volt counterparts. For additional details, you may find our article below helpful:

https://www.waveformlighting.com/home-residential/advantages-of-a-24v-led-system-vs-12v

The junction box is an optional accessory for the power supply but can be useful for mounting the power supply safely and securely.

In terms of dimmer compatibility, our dimmable power supplies are designed to work with the majority of Lutron and Leviton dimmers. Below is a list of all dimmers we have tested for compatibility:

https://www.waveformlighting.com/files/DC_3093.pdf

We do see both the MACL and MRF2 series dimmers on our tested list (I believe the letters and digits that follow are designators for non-electrical variations such as color, etc), so I do believe that either of those options should work well for your installation!

I don't believe we have any further guidance or recommendations, but you may want to review the following layout map for a visual preview of what you have in mind for the installation configuration:

https://www.waveformlighting.com/layoutmaps/3001_1B

Do you have a flicker-free controllers for the RGB LED strip lights?

I have epilepsy so I’m very interested in these flicker free LED’s. I want the RGB color changing LED strip. Do I have to get the FilmGrade one to get the flicker free or does the ColorSpace give me flicker free as well? 

Unfortunately we do not offer any flicker-free controllers for the RGB LED strip lights, so that this will be much more challenging to accomplish a flicker-free LED strip set up.

​On the other hand, the FilmGrade White LED strip lights can be controlled with our FilmGrade power supply and FilmGrade LED dimmer, providing for completely flicker-free light output. Please see below for a installation diagram for your reference:

​https://www.waveformlighting.com/layoutmaps/3002_3D

LED Strip Lighting for Floating Shelves

I want to use strip lighting on 4 individual shelves, 2x2ft, and 2x3ft. Two shelves are mounted on either side of the TV. I want to use the existing wall switch for on/off and feed power from the attic down as I’m on the slab. Ideally, I would like to have voltage conversion in the attic and feed 12v/24v wiring out a hidden hole behind each shelf to led strips. Can you provide suggestions and equipment list? 

Based on the details provided, it appears that your installation can be accomplished using one unit of the 16.4 ft reel of LED strip lighting product divided into the 2 and 3 ft segments, as well as one unit of the TRIAC dimmable power supply in order to connect the LED strip lights to the wall switch and wall wiring. 

​It might also be helpful to note that our LED strip light products are available in both 12V and 24V. As such, it will be important to select the appropriate power supply voltage option.

​You may also find value in the below wiring products, which can be utilized for connecting the power supply to the LED strip lights, as well as connecting the LED strip segments together.

LED Strips and Accessories for Under Cabinet Lighting

For under cabinet lights, I believe I have everything needed. Please check this and make sure I have everything needed and recommend any additional items or different items that would be better. The kitchen lights would have two zones, each turned on and off individually. Off of one power supply and one dimmer, there would be two parallel light loops each with its own on/off switch. 

PN 3003.27 (16 ft), PN 3092 , PN 3081 , PN 7094 , PN 3060 

We've reviewed the proposed purchase list and confirmed that the items are sufficient for your installation. During checkout, please be sure to select the correct 24-volt LED strip light option (PN 3004.27) to pair with the 24-volt power supply (PN 3092).

​In terms of the required components and parts, it appears that our installation diagram shown in the link below would be the closest representation of the proposed installation:

https://www.waveformlighting.com/layoutmaps/3002_2D?px=-2154&py=-2089&pw=1308&ph=1178&s=0.1

​The main difference, of course, is the single LED strip run as opposed to the two separate runs you have in your proposal.

​With respect to the two parallel runs that are to be switched separately:

I plan on using a 110V AC wall switch as with a shallow box it tucks up underneath the cabinet, is hardly visible, and works very well. I don't see any switches like this on your website so if this switch won't work could you suggest a switch (with a mount if necessary) that will fit under the cabinet?

Would the power supply be harmed if the output is an open circuit?

As for the power supply, FilmGrade™ DC Power Supply for LED Strip 3092, can it mount in the cabinet above the microwave?

Can extra end caps and mounting brackets be purchased?

From an electricity perspective, I do not see any concerns and agree with you that the switch should be able to handle 24 volts and 5 amps. If there are electrical code compliance concerns, however, I would be sure to double-check as I know there tend to be some strict requirements in terms of product fit, even if it may be deemed safe from an electrical and fire safety perspective.

We, unfortunately, do not sell and switch products, but I would perhaps recommend searching for a third-party supplier for a dedicated DC switch. I do recall seeing a few "DC inline style" switches that could be used, for example, this product here (please check for max current limitations).

Next, if we have understood your question about the open circuit correctly, there will be no issues in terms of power supply damage or reliability. The open circuit would be electrically equivalent to powering the power supply without plugging it in anywhere (as is common with laptop chargers, etc).

Generally speaking, the power supply does require open airflow for sufficient cooling. However, if running the LED strips at 48 watts, the heat generated will be limited and should not be a concern for the suggested installation.

Yes. We do sell extra mounting brackets and end caps as separate items. Please see the product page below:

Do you have different product variants that allow the LED strips to lower brightness? 

We are interested in purchasing an LED strip we previously bought an LED strip with 9W 24V and 3000K. But after fitting it inside the LED profile and fixing it inside a kitchen cabinet it's still too bright that we have to cover it with silicon inside. Kindly advise if you have something suitable for our needs.

​Unfortunately, we do not have any different product variants that would allow for lower brightness. We would recommend one of two options:

Dimmable Power Supply for the Centric Home LED Strips

We have a wall dimmer and will be using the 3000K Centric LED strips. I'm wondering about power supplies. Does it seem your Centric flicker-free ones don't have an option for a junction box being included? And your Triac dimmable ones don't seem to be flicker-free but do have a junction box? But you don't have a flicker-free with junction box?

First of all, you are correct that only the "TRIAC dimmable power supply" product includes a junction box option. Our most recent production batch of this product, however, incorporates flicker-free performance, and you will see the same level of flicker performance as the CENTRIC SERIES power supplies. As such, should you require both flicker-free performance and a corresponding junction box, the TRIAC dimmable power supply should be a perfect option for you.

​

Dimmable LED Lights for Kitchen Cabinet Installation

I have an electrician coming after the first of the year to install uplighting above my kitchen cabinets. Any suggestions? Would like it hardwired. Dimmable too? 

Our LED strip lights have been a very popular option for under and above cabinet lighting installations. Please see below for the product link.

This installation can indeed be hard-wired and dimmable. Please see below for an installation diagram that shows the components and configuration needed:

https://www.waveformlighting.com/layoutmaps/3001_1B

LED Dimmer Compatible with Centric Daylight LED Strips

I have one Centric Daylight Strip that I would like to be able to dim without flickering. There is a possibility that I may add more strips later and I would want to be able to dim all of the strips at the same time. Can film grade dimming be accomplished using a standard wall dimmer or is there a way to gang the Film Grade Dimmers?

The FilmGrade dimmer is a standalone dimmer unit, so it would not be well-suited for use in an installation where synchronized dimming is required.

​As an alternative, we would perhaps recommend our TRIAC dimmable power supply units, which can be wired in parallel and synchronously controlled from a single dimmer switch. The product provides the flicker-free output and you should see comparable flicker performance. Please see below for an example layout of how this can be accomplished:

https://www.waveformlighting.com/layoutmaps/3001_1C

Is it possible to use a single knob to transition from RGB to white tunable?

If I bought a 5 in 1 LED light with the DMX Dimmer and the power supply, Would it be possible to use a single knob to transition from RGB to white tunable?

While our DMX decoder would be a great option for our 5-in-1 LED strip lights, the controls are accomplished via digital signals only, so there would unfortunately not be any knobs or dials that could accomplish this.

​That being said, there may be some third-party DMX controllers which incorporate analog inputs that can be programmed to achieve the functionality you are looking for.

LED Strip Lights for Stair Lighting Installation

I have a staircase with 16 steps. Each step is 32" in length. They need to be hardwired to 120V. I want to have a timer so that they come on in the evening (7:00 pm) and off in the morning (6:00 am). Single color with blue being prefer, but white will also work. I'm having a difficult time putting this package together. Can you help by recommending the items that I would need for this project? 

To start off, our SimpleColor Blue LED strip lights sound like a great option for you. These LED strip lights feature just a single color light output and should provide you with the simplest lighting installation. Below is the product link for your reference:

In terms of spanning each of the 16 staircase steps, the configuration will require a bit of careful planning due to some limitations in the "maximum run length" per LED strip light.

​For the SimpleColor Blue LED strip lights, the maximum run length is 16.4 ft. If I have done the math correctly, this means that each run can cover 6 steps at a time (6 steps x 32 inches / step = 16 ft). In order to cover all 16 steps, you will require three separate runs, each powered with an independent power supply.

Depending on the distance between each of the stairs, you will likely want to use PN 3071, or a combination of PN 3070 + PN 7098.

​The power supply we would recommend in this installation would be our TRIAC dimmable power supply, which is designed to be hard-wired to the wires in your wall. To control the lights on a timer, you may want to consider using a "smart home" type dimmer switch such as the third-party Lutron Caseta, which can be programmed to turn on and off at certain times during the day.

​Below is a configuration diagram for our CENTRIC HOME LED strip lights, which uses the same 12 volt low voltage architecture and may be useful for better visualizing the wiring needed to complete the installation:

https://www.waveformlighting.com/layoutmaps/3001_1C

Please note that you may want to consider using PN 7095 to connect the power supply output wires to the LED strip DC input jacks:

Finally, should you prefer a plug-in approach, our FilmGrade LED power supply can also be a nice alternative that can also be programmed using a third-party electrical timer similar to those used for Christmas tree lights.

Will the CRI change when the LED Strips are dimmed?

If I reduce the brightness of a LED strip (dimming) will be the CRI the same as before? Or the CRI is a constant value, like a feature or how to define, a "passive skill" so does not matter that I reduce a 20W LED strip consumption to 10W and reduce the brightness highly, the CRI will stay constant, and the same as before? 

When LED strip lights are dimmed via PWM, the LEDs are pulsed "on" and "off" at a very rapid rate. During the "on" phase, the LEDs will exhibit the same color and spectral properties as when the LEDs are at full power. During the "off" phase, the LEDs are completely turned off.

(Here is some additional information on the PWM frequency as it relates to flicker-free dimming).

​With PWM, various brightness levels are achieved by adjusting the ratio of the time between the "on" and "off" phases (aka PWM duty cycle). Since the quality of the light during the "on" cycle remains the same regardless of the PWM duty cycle, we also see that the CRI value will remain constant across the dimming curve.

What if I use another dimming way, like resistance with a potentiometer? So when we control the current or voltage they will get, then what does happen with CRI? If so, then the only good way is PWM, but does PWM work only with a PWM receiver or can it work without a receiver? 

If you are looking to implement your own dimming solution, using a potentiometer or voltage splitter can be an option. With high-power LED strip light installations, however, this is known to be tricky due to the high amounts of energy that must be dissipated. (This is why PWM is usually the preferred method for dimming in high-power LED installations).

For an example of a PWM dimmer, please see our inline dimmer product below:

If you were to reduce the brightness of the LED using current or voltage reduction, you may see some changes to CRI. Based on the data I have seen, however, the changes are typically in the 1-2 point range and are not significant.

Is your PhotonPanel™ 100W Grow Light Panel and Dimmer UL listed?

We are planning a growth area and would like to daisy chain 3 panels to be on three separate shelf levels but to have them be dimmable -- and were looking at your PhotonPanel™ 100W Grow Light Panel and the FilmGrade DC Power Supply and FilmGradeTM Flicker-Free LED Dimmer. 

We must have UL-listed components. I have purchased some LED panels to test out with plants, but sometimes it is too bright and so I believe dimmable would be useful. Is there a way to do this with your products? 

Unfortunately, apart from our power supplies, the grow light panel and dimmers are NOT UL listed at this time.

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

LED Tape Lights and Controller for Channel Lighting

I'm interested in installing LED tape light / channels into a few rooms. I would like to use the tape lights that feature both a warm and cool mix of LED's so the warmth can be adjusted. How can I drive and control such an install? I currently use networked Lutron Dimmers on conventional 120V fixtures.

It's currently quite difficult to achieve the color tuning functionality using traditional wall dimmers such as those offered by Lutron and Leviton, as these dimmers are only capable of adjusting brightness, and unfortunately not color.

Another option would be to search for third-party controllers which can wirelessly control the output (brightness and color) using a remote control. Below is an example of a product which would achieve this:

Are you aware of any dimmable DC power supplies that could be controlled from a conventional Casetta dimmer / remote?

Our TRIAC dimmable power supply units have been tested with Lutron Caseta, and should meet the requirements you outlined in the most recent email. For more information, please see our article below:

https://www.waveformlighting.com/home-residential/dimming-led-strip-lights-and-led-bulbs-using-smart-lighting-systems

Does the TRIAC dimmable power supply referenced produce a ripple free clean DC signal, or is it a rectified / modified 120Hz pulse?

The TRIAC dimmable power supply's output is flicker-free by virtue of its very high PWM frequency. The frequency is > 20,000 Hz, which makes any stroboscopic flicker virtually undetectable.​Strictly speaking, however, since it is a PWM signal, it is not a flat DC current flow.

What tape light would you recommend that has the LEAST amount of green in the spectrum, and the most (Far) red?

​We would suggest the 2700K as it has the most amount of red phosphor, and therefore, by extension, the most amount of far-red energy as well.

The amount of green across the various color temperature options is likely to be similar.

LED Lights Recommendations for Digital Photo Studio

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

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

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

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

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

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

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

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

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

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

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

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

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

Anything else you would advise or suggest that I consider?

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

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

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

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

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

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

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

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

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

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

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

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

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

How to control the color temperature of FilmGrade™ HYBRID LED Strip Lights?

What is needed to control the color temperature of FilmGrade™ HYBRID LED Strip Lights? 

The first method would require the use of a DMX or controller solution. Below is an example of a third-party controller available on Amazon: https://www.amazon.com/LEDUPDATES-Controller-remote-Temperature-Changing/dp/B07DVHXGTD/

​Alternatively, you can also use a combination of two inline dimmers to control each color channel independently. The product link is below: https://store.waveformlighting.com/products/filmgrade-flicker-free-dimmer-for-led-strip

Additional accessories and components are needed for this approach, which is outlined in the connection diagrams shown in the article here. 

FilmGrade™ HYBRID LED Flex Panel - Transformer & Dimmers

Our architect specified your product - FilmGrade™ HYBRID LED Flex Panel. We have already purchased one panel and would need to order 7 more. We are also looking for a transformer that would be able to power 8 panels at the same time and two dimmers - one regular and one for switching the colors. 

Can you please advise on the product that would be suitable for this project? 

Our LED flex panel requires 50 watts per color to operate. If both colors are to be operated simultaneously, each panel will require up to 100 watts.​As such, 8 panels will require 800 watts to operate. This is a very high power capacity level and we, unfortunately, do not have any products which can support this configuration. Instead, we would recommend operating each panel with an independent power supply unit.

If we follow your recommendation and operate each panel with an independent power supply unit, would you be able to provide this unit?

Can you please advise on the quantity we would need and a price per one? 

Each power supply unit costs $49, and the link to the product can be located below.

Each of these power supplies would be sufficient for one panel. Therefore, for 8 panels, you will require 8 power supply units. You will also need a third-party controller to vary the color and output of the panel. (The sample setup you have from the one panel should simply be replicated by a factor of 8).

Can you please also advise if this power supply unit will work for dimming and color-changing? If not, will it be compatible with Lutron Caseta dimmer? 

Unfortunately, our product will not achieve the color-changing features you are seeking.​Do you have information on how you had the single-panel sample unit set up? Please let me know and I can assist in replicating that setup for you.

You mentioned earlier, that we would need a third-party controller to vary the color and output of the panel. Can you please advise if this device from your website can be used for dimming and color-changing? 

If not, can you recommend a different product? 

We want to be able to dim 8 panels from one dimmer at the same time, and also change the colors on all 8 panels from one device at the same time. 

We would recommend daisy-chaining eight of our DMX decoder units, controlled from a single DMX controller. Below is the product link:

LED Lighting and Dimmers for Laundry Room Lighting

I'm hoping you can help me a little with my laundry room lighting. Here are the specs: basement location - 1 small window in a well (almost no natural light). Room is 7.5' by 11.8', ceilings is 7.5' high (currently lit by a 4 t8 tube troffer fluorescent light in a drop ceiling). Block wall is off white -all wiring is surface wiring in conduit. 

Our high CRI LED products sound like a great fit for your retrofit installation, and the use of our LED strip lights in your fluorescent fixtures sounds like a great idea.​I don't foresee any issues from a performance perspective, but if there are any electrical code or inspection concerns, we would recommend confirming that this is a permissible installation method as regulations can differ depending on the specific inspectors as well as authorities having jurisdiction.

One alternative option would be to keep the fluorescent fixtures in place and utilize our T8 retrofit lamps, which offer the same level of color quality.

Should I use 2 strips or 4 by my calculations 4 would be giving me almost 8000 lumens, and this is not a baseball field. Will 2 strips look like 2 long blobs up there? or will I have even light over the troffer? 

I inputted the provided room dimensions into the lumen estimation calculator (https://www.waveformlighting.com/lumen-calculator). Based on a target of 60 footcandles (which should provide you with a very nice level of brightness for most laundry-related tasks without being overly bright), the recommended lumen output for the lights would be approximately 6000 lumens.

​Your calculations are correct that four 4-ft rows of the LED strips would provide you with approximately 7200 lumens (450 lumens per foot * 16 feet). I do not think this is an unreasonable amount of light, especially if you have a troffer diffuser that will reduce the light output a bit.

I'm a little confused about dimmer options...I see that you have a triac dimmer compatible power supply. Are all wall dimmers triac? or just the standard incandescent ones. Do I still need to get an LED or other specialty dimmer from Lutron etc...i.e. low voltage electronic dimmer?

Most wall dimmers utilize TRIAC phase dimming, and our TRIAC dimmable power supply is compatible with most standard residential wall dimmers. Some of the most commonly seen wall dimmer brands include Lutron and Leviton. Please see below for a list of dimmers which we have tested compatibility for: https://www.waveformlighting.com/files/DC_3093.pdf

 I was thinking I would use the 24 v option since I might like to run some of the strips in the hallway outside the laundry room and that would require a little more distance between the power supply and strip light. Does that make sense? I will be having an electrician do the actual installation.

Generally, 24 volts is almost always a better option when running longer wire connections. This is because a higher voltage option requires lower amperage, which is typically what causes voltage drop issues. For additional information on voltage drop, please see our article below: https://www.waveformlighting.com/home-residential/what-is-led-strip-voltage-drop

In order to connect my troffer strip to the next strip out in the hallway, I would use your 16 gauge wire that you sell by the spool, I believe. Would I be using the strip to wire pigtail connector that you sell? If so, how do I join the two wires? wire nuts in a junction box? or is there a way to solder the wire to the strip at either end and add a cover for protection?

The best way to accomplish this connection would be to use our PN 3070 solderless connector, joined to the 16 AWG wire using wire nuts. Please see the screenshot below, taken from the layout maps found at this link: https://www.waveformlighting.com/layoutmaps/3001_1B

You may of course also forgo the PN 3070 component and solder the 16 AWG wires directly onto the LED strip copper pads as needed.

Also, is it possible to buy smaller quantities of the various connectors? I don't want to buy 10 if I only need two.

Unfortunately the connectors are pre-packaged packs of 10 and we would have no way to offer just two of them. Sorry for the inconvenience!

Does your power supply require a neutral wire for dimming?

Your webpage shows a nice diagram using a Lutron dimmer. The Lutron dimmer I wish to use is the Caseta plug-in dimmer, P-PKG1P. It has two output plugs. Both plugs are two-wire, not three-wire plugs. Does your power supply require a neutral wire for dimming? If so, I could rig one.

If your dimmer does not have a neutral wire connection (it should just have two black wires), ​the TRIAC dimmable power supply's neutral wire can be connected directly to the neutral wire in the wall.

Which power dimmer switch should I order to work with your 220v power supply?

I am writing from Europe and planning to your LED stripes and dimmable power supplies for my new large bathroom project for barrisol ceiling (smth like this - https://youtu.be/QeMlIcZOlO0) As long as voltage here is 220v I am looking for proper dimmer switch (lutron for ex.) When I go to Lutron webpage every switch states it is meant for 120v. Can you please advise which switch should I order with your system to work with 220v? 

We currently do not have any specific compatibility test data for non-USA models of dimmers that can be used with our TRIAC dimmable power supply.​The dimmable power supply is designed to be compatible with phase dimmers in general, however, so you should find that most dimmer models available locally (including at 220 volts) should work with our product, without any issues.

realUV LED Strip Lights for Cabinet with Uranium Glass

I have 5 shelves that are 3' by 2' with uranium glass that I want to 'glow'. Planning on purchasing a 5m 365nm realUV LED strip and cutting it into 5 pieces. Question: based on your Watt estimator, 3' of LED strip is a lot of coverage for 6 sq ft of the shelf. Will I want a dimmer? Side note: I wish you had longer connector wires. Shelves are 1.5' ft apart. I can kludge together with extra connectors/wire/wire-nuts, but will not be a real clean look. 

While we have not done any tests in-house, we do believe that our realUV LED strip lights will work very well for uranium glass, and have had several customers report success with similar projects.

You are correct that our UV LED strip lights do offer quite a bit of output per foot, so you may not need as much power to achieve the fluorescence effects you are after. In general, however, having too much UV intensity is not necessarily a bad thing, as the fluorescence effects will tend to hit a "ceiling" once a certain UV intensity level is reached.

That being said, we do offer an inline dimmer that could very well be used for your installation should you prefer to have control over the UV intensity. The connection diagram can be found at the link below:

https://www.waveformlighting.com/layoutmaps/7021_4D

Finally, we sincerely appreciate your feedback on the solderless connector cable length. I'll definitey have our team consider a longer cable product for future product development.

In the meantime, our PN 7098 cable product will likely be your best workaround. For a cleaner installation, if you are comfortable, directly soldering the wires onto the copper pads may also be an option for you.

When you say ‘solder onto the copper pad’, are you suggesting that I could remove the wire from PN 3070 and solder in the new, longer length of wire? I’m very comfortable with soldering and that would be a great option! 

The LED strip lights, once they are cut, will have solder pads exposed and accessible. The photo below shows the copper semi-circles right along the cut-line:

​From there, the PN 7098 wires can be tinned, and then directly soldered onto the copper semi-circles. This assembly will essentially replace and negate the need for PN 3070 / 3071 altogether.

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.

Power Supply Recommended for a Goal Zero Solar Setup

I want to run a 12V LED filmstrip with a dimmer from a Goal Zero solar setup that has USB and cigarette lighter plug (or direct battery terminal) connection options. Will the dimmer work in this scenario, and do you offer any of the power supply options, or do you have product recommendations? I don't know much about wiring so prefer no soldering or splicing, or at least having product-specific recommendations. 

While we have not tested the Goal Zero product, based on a quick review of their product specifications, it does appear that the 12-volt output provided via the cigarette lighter port would be able to power our LED strip lights and dimmer.

​To connect the cigarette lighter plug to the dimmer, you may want to consider a third-party product such as the one below:

​From there, you may benefit from referencing our Layout Maps which show the connectivity of the dimmer and LED strip lights. In your case, you would want to ignore the DC power supply unit, since the Goal Zero unit already outputs 12 volts DC.

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

Why are there two 12-24vdc+ and two 12-24 VDC - inputs?

The FilmGrade DMX decoder has two sets of 12-24 volt input ports to allow for more than one power supply input. This may be advantageous if the DMX decoder is used at higher amperage levels, as this can help mitigate power supply capacity and input wire voltage drop issues.

Compatible Power Supply for Lutron Caseta dimmer

I purchased some high-quality LED light strips (60 ft in total) and I am looking for a power supply that would work with a Lutron Caseta dimmer. Your 24V PSU is rated 96W/4A but it states it can only work for 16 ft light strips. My LED strip requires 96W at full power. Would your PSU work for this?

Our TRIAC dimmable power supply is indeed compatible with the Lutron Caseta dimming system, and can safely operate LED strip loads up to 96 watts. If the load exceeds 96 watts, the system will automatically shut off to protect itself from being over-driven.​We generally recommend leaving a 10-20% headroom above the LED strip power rating as an extra safety margin. The reason we recommend this safety margin is due to the variability of actual power draw performance of LED strip products. Your LED strip light product with a 96 watt rating, for example, is likely specified at 96 watts +/- 10%, which would suggest that the actual power draw can be anywhere between 86 and 106 watts.

One workaround would be to reduce the total length of LED strip connected, to ensure that the LED strip power draw remains well below the 96 watt level. This would, of course, require that you can accept a shorter run length than you currently have planned for.

Do you have a model above 96W? I wanted to stick to Class 2 rating but that's hard to do that with my setup.

Unfortunately we do not have any thing that is simultaneously dimmable and higher power than 96 watts.

One alternative would be to split your LED strip run, and use two of the 96 watt dimmable power supplies connected to the same Lutron dimmer. Please see below for a connection diagram showing how this would look:

https://www.waveformlighting.com/layoutmaps/3001_1C

I ordered a Magnitude driver but, I want to test it because I saw reviews saying they flicker.

Now, you Centric series are rated flicker free. What about the regular Triac driver? Does it have flickering issues? 

The TRIAC dimmable power supply is also flicker free and you should not see any of the issues you are seeing with the Magnitude products.

I purchased a 60 ft strip like this one: Super Length 20 meters Constant Current DC24V 120leds/m SMD2835 LED Strip Light (coxotech.com). It is a high quality LED strip that uses integrated ICs to convert constant voltage to constant current (if my understanding is correct). Do you know if you LED drivers have PWM output or constant output?

Our TRIAC dimmable power supply units use high-frequency PWM (> 20,000 Hz) to achieve what is effectively flicker-free light output. (Typical flicker issues occur at or 2x line frequency, in the 50-60 Hz or 100-120 Hz range).

If the supplier of the LED strip lights you have in mind are certain that PWM is incompatible, that would unfortunately suggest that our TRIAC dimmable power supply would not be a suitable product pairing.

LED Lights to Stimulate Daylight for Winter Depression

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Difference between FilmGrade and ABSOLUTE SERIES™ 99 CRI 5000K (D50) / 6500K (D65)

What is the difference between Film Grade vs. ABSOLUTE SERIES™ 99 CRI 5000K (D50) / 6500K (D65)?

The primary difference between the FilmGrade and ABSOLUTE SERIES LED product lines is the color rendering index. The FilmGrade product line has a CRI rating of 95, while the ABSOLUTE SERIES LED products have a CRI rating of 99.

Furthermore, the FilmGrade product line is offered in 5600K and 6500K, while the ABSOLUTE SERIES LEDs are offered in 5000K and 6500K.

Are these lights DC powered?

Yes, our LED strip lights and LED modules are powered via 12 volts or 24 volts DC. They will require a dedicated power supply to operate.

Do either of these lights flicker? 

If the LED strips and/or modules are powered via our power supply units, they will not produce any flicker.

Can I wire these lights in parallel (2 1-foot strips side by side)?

Yes, they can be wired in parallel, as long as the total connected length does not exceed the maximum power capacity of the power supply (e.g. do not exceed 16.4 ft for LED strips, in total). For additional information, please see our article below:

https://www.waveformlighting.com/home-residential/connecting-led-strips-in-series-vs-parallel

Or must I have a power supply for each strip of lights?

As long as the total power draw remains below the power capacity of the power supply unit, you should not see any issues. Below is a calculator which you may find helpful:

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

How can I order a sample 6-inch strip plus a power supply?

Please see below for the direct link to the 6-inch LED strip sample pack, which includes a power supply unit:

How can I link separate strips together? Do you have a picture of this showing the connector? I want to link 4 l foot strips side by side.

You may find our Layout Maps helpful. Specifically, see below for an illustration showing how multiple sections can be connected:

https://www.waveformlighting.com/layoutmaps/3002_3E?px=-2183&py=-2023&pw=1366&ph=1046&s=0.1

Do the link connectors come in the 16-foot reel kit? 

The LED strip reel includes DC power ports pre-installed on both ends, so you will be able to connect the power supply directly to the DC port without any issues.​The PN 3071 solderless connectors can come in handy if you're looking to cut the LED strip reel into shorter segments and are looking to reconnect them.​Finally, the 6-inch sample pack also includes all of the components to set up a short 6-inch demo circuit.

Does Waveform make housings for these lights? Can these be cut?

Please see below for our aluminum channels which would be a great option for housing the ABSOLUTE SERIES LED strip lights:

Cuttability is not an officially supported feature of the aluminum channels, but I have had customers report that this can be done quite readily using a hacksaw.

TRIAC Dimmable Power Supply Compatible with Centric Home LED Strips

Can I use the TRIAC dimmable power supply with Centric LED strips?

Yes. We're happy to confirm that the TRIAC Dimmable Power Supply for LED Strip products is compatible with our CENTRIC HOME™ LED Strip Lights for Home & Residential and CENTRIC DAYLIGHT™ LED Strip Lights for Commercial & Retail products.

Below is the layout guide, which illustrates the configuration of these products.

LayoutMaps™ LED Strip Light Layout 3001-1A: https://www.waveformlighting.com/layoutmaps/3001_1A?px=-4896&py=-3269.5&pw=1464&ph=1491&s=0.125

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.

Does your TRIAC Dimmable Power Supply use high-frequency PWM?

I would like to ask if your TRIAC Dimmable Power Supply for LED Strip (3093.120) uses high-frequency PWM to dim the actual LED strip on the output side or uses PWM at the mains frequency.

I read your very good article which suggests that flicker-free PWM dimming needs to be at 25kHz or so. I live in New Zealand & we use 230VAC at 50Hz. I wish to adapt the existing 230V wiring to accommodate a dimmable LED strip. 

Our TRIAC dimmable power supply does indeed use high-frequency PWM on the output side to dim the LEDs. The PWM frequency is 25 kHz, which should be high enough for even the most sensitive or demanding of applications.

​On the AC input side, the power supply "interprets" a phase-dimming signal (commonly called TRIAC) which is produced by traditional wall dimmers in residential installations.

If you have a standard AC 230-volt mains voltage dimmer installed, our dimmable power supplier would be a great fit for the installation.

For additional guidance on installation, please see our layout map below:

https://www.waveformlighting.com/layoutmaps/3001_1A

How do I know if the LED sign is compatible with Flicker Free LED Dimmer?

I just recently purchased an LED sign. It flickers on video when dimming. How do I know if that LED sign is compatible with your dimmer?

We can confirm that our FilmGrade™ Flicker-Free LED Dimmer is compatible with LED systems at any voltage level between 6 and 60V DC and < 10 Amps of current draw. If your LED sign exceeds this voltage, we expect that the dimmer would be incompatible.

However, if there are compatibility issues between the dimmer and your LED sign, we would be more than happy to issue a return label to have the item sent back to us for a refund.

Reducing the Visible Light Output of realUV LED Light

I was hoping the 365nm realUV product would be somewhat invisible to the human eye considering the extra expense. It casts less visible light than some other products I've purchased in the past, but it is still bright enough to cast shadows in a dark room. Can I dim the LEDs somehow or is there a product with less spread into the visible spectrum?

Unfortunately, we currently do not have a way of reducing the visible light output as this is a part of the small residual amount of visible wavelength energy that "leaks" beyond the threshold of UV wavelengths.​A LED strip dimmer may significantly help reduce the amount of overall brightness. While this will certainly help reduce the amount of visible light, this will also unfortunately reduce the amount of UV output as well. If, however, you are seeing that you can accept a lower amount of UV energy, this may indeed be a great workaround solution for your situation.

LED Lighting and Dimmers for Entertainment Center

The plan is to recess the LED strips behind the face boards. The part that I am finding most difficult is the dimmer (or maybe I’m just screwed up on everything). The LED lights need to have the ability to select a color including white. I need the width of the LED strips to be 10mm or less and the height to be as low as possible. We want a remote-controlled dimmer that can be used to change the colors and brightness of the LED lights. Can you please review and provide me with an itemized list of the materials that I need to complete this project?

Unfortunately, we currently do not have any remote-controlled dimmers or power supplies available which would be capable of changing the color and brightness of the LED strip lights. Most of our customers that utilize our color-changing LED strip lights are in the entertainment or theatrical industries, where DMX systems are commonly used.

​For a more consumer-friendly remote-control solution, we would recommend searching for third-party providers of such products.

In terms of our LED strip options, our ColorSpace RGB LED strip light may be a good fit for your needs. The product features an 8 mm width, high brightness, and very narrow wavelength tolerances to ensure consistency within and among LED strip runs.

Furthermore, you may also find that our FilmGrade™ FiveSpect 5-in-1 LED strip lights may be of interest to you. This product is designed to have a high level of customized light spectrum output with the inclusion of a warm white and daylight white channel, in addition to the standard RGB channels.

To connect the LED strip lights to the power supply, we recommend our Solderless Connector Cable for a 5-in-1 LED Strip product.

Regarding the mounting of the lights within the structure, we currently do not offer mounting channels which would accommodate the 12mm width of the FiveSpect 5-in-1 LED Strip Lights. That being said, there may be third-party options available that could diffuse the light.

LED Strip Lights Compatible with Lutron Caseta Dimmer

I have a Lutron Caseta dimmer connected to rope lighting in a tray ceiling. I am having trouble finding LED strip lights to replace the rope lighting. Do you know if your LED strip lighting will be compatible and fully dim with the Lutron Caseta dimmer switches?

We are happy to confirm that our LED strip light products are compatible with the Lutron Caseta system.

To integrate our LED strip lights with the Lutron Caseta system, they will need to be connected to a dimmable power supply, such as our TRIAC Dimmable Power Supply for LED Strip. The dimmable power supply will then need to be connected to a dimmer, such as your pre-existing Lutron Caseta dimmer switch. During our testing of this configuration, we found that the dimming range was 0.2%-100%. 

​However, there are certain limitations to consider. For instance, not all dimmable power supplies are compatible with the Lutron Caseta system. Further, the Lutron Caseta system only works with single-color LED strip lights, and can only provide brightness control.

For more information regarding the integration options, we recommend the below article from our website.

Dimming LED Strip Lights and LED Bulbs using Smart Lighting Systems: https://www.waveformlighting.com/home-residential/dimming-led-strip-lights-and-LED-bulbs-using-smart-lighting-systems

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.

Flicker Free LED Strip Lights

Do you offer LED strip lights that are flicker-free? I'm considering Filmgrade White LED and Absolute Series LED strips. Are these flicker-free? Am I correct in assuming that the benefits of the Filmgrade flicker-free dimmer apply only when the light is dimmed and not at 100% output?

When any of our LED strip light products are paired with the FilmGrade™ DC Power Supply for LED Strip product, they gain the ability to be flicker-free.

When the LED strip light products are paired with both the FilmGrade™ DC Power Supply for LED Strip as well as the Flicker-Free LED Dimmer, they gain the ability to be both flicker-free as well as dimmable.

In this configuration, the LED strip lights will remain flicker-free at any level of dimming, from 0% to 100%.

Color Tunable Recommendations

Would it be possible to send me a lecture about wiring your product to a lighting control system as a Lutron homeworks with dimming and color-tunable?

Unfortunately we do not have any support for color tuning of our products using Lutron systems. If you have any additional information on the specific Lutron product you are interested in, we would be more than happy to provide further information on our color tunable products to see if they would be a good fit.

For standard single-color dimming, our layout diagram below may be of help for you:

https://www.waveformlighting.com/layoutmaps/3001_1B?px=-2395&py=-2315.5&pw=1790&ph=1631&s=0.1

We want to use the Filmgrade Hybrid Led Flex Panel 3004 HY. We can use Lutron Caseta with GRX-tvi to have ability to dim 0-10V.

A few comments:

As such, it does not seem that our hybrid LED flex panel would be compatible with this system as it requires a low voltage DC system (i.e. 24 volts DC) with dimming control over channels (warm white and cool white). 

Dimmable 3000K (>90) CRI 3000K Strip Lights with Triac Dimmer Switches for an Open Staircase Installation

I wish to put Strip Lights on an open staircase under each tread. I need help in determining the correct method to instruct the fabricators to install wires and what combination of power supplies/dimmers to use. I have 17 treads, each will have 48" of illumination - for a total of 21M. 

I intend to have each tread individually drop wires to the basement so that I can wire them all independently (would you recommend this?). I would like to do white, dimmable strip lights with high (>90) CRI, and so I’m looking at the centric home, 3000K strip lights. What’s the best way to do this? The Triac Dimmer switches indicate 150W only – so how would I use multiple power supplies (each at ~120W) with a single dimmer?

Our CENTRIC HOME LED strip lights sound like a great fit for your staircase installation. The 3000K and 95 CRI colors will be sure to add some excellent lighting to your space while highlighting your staircase.

There are several ways the proposed installation can be accomplished. The constraint, however, will be in the power capacity limitations of our TRIAC dimmable power supplies, which are 120 watts and 96 watts, for the 12-volt and 24-volt versions, respectively. Converting that into the number of stair treads, it looks like each power supply will have enough power to cover approximately 4 stair treads (5.5 watts x 4 ft x 4 stair treads = 88 watts).

As such, you will likely need 4 or more separate LED strip runs to be able to cover the entire staircase, with each run being powered by its own TRIAC dimmable power supply. The good news is that the 4 TRIAC dimmable power supplies can be connected to a single dimmer switch so that all of the LED strip runs can be dimmed in unison. For a connectivity diagram, please see our layout diagram below:

https://www.waveformlighting.com/layoutmaps/3001_1C?px=-2395&py=-2315.5&pw=1790&ph=1631&s=0.1

Additionally, in connecting the separate 48" sections between the stair treads, we do offer a variety of connectors that you may find helpful. Please see below for a similar diagram but with separate LED strip segments being rejoined using our various accessories:

https://www.waveformlighting.com/layoutmaps/3001_1B?px=-2395&py=-2315.5&pw=1790&ph=1631&s=0.1

It's mentioned that I can use a single Triac Dimmer to control 4 dimmable power supplies. However the dimmer indicates only ~100W for LED - and each of the power supplies would be ~100W x 4 =400W total.

Your calculation and interpretation there is correct. If the dimmer manufacturer recommends only a minimum of 100 watts, we certainly would not recommend exceeding that level.

We have generally seen that many dimmers support up to 600 watts, with a list of supported dimmers located here:

https://www.waveformlighting.com/files/DC_3093.pdf

We have found that dimmer manufacturers have been providing two different wattage levels for incandescent / halogen and LED / CFL systems. We are not sure what their reasoning for this is, as we believe that our dimmable LED power supplies behave similarly to dimmable incandescent loads and therefore should not be significantly different.

​To ensure safe operation, however, we would recommend following the guidance of the dimmer manufacturers as they may have their reasons for the maximum ratings.

Absolute Series LED modules for a color matching to a Pantone swatch book and small item product photography.

I am interested in the Absolute series LED modules, I just realized the modules won't fit into the aluminum channels you offer, so I'm not certain what to mount them on or use as a diffuser. Do you have any recommendations? Is the type of diffuser material likely to affect the CRI at all? 

I was also wondering about the brightness - each module produces 800 lumens. 

I am also thinking about getting one of your dimmers, is the panel with 2 modules likely to be too bright to use at full strength? 

I was also thinking about trying the North Lux light bulbs, but wasn't sure about the socket type - I'm in the UK. I noticed the Centric Daylight bulbs have an E27 European option though, are those actually the same bulbs as the North Lux? What is the actual CRI for either of these bulbs? The item page says they have a CRI of 95+, and an R9 of 80+, but the photometric report seems to suggest both of these are much higher. Am I reading it wrong? 

I was planning on getting the D65 modules as I'm used to working with natural daylight color temperatures. The Pantone color bridge I'm using says to use D50 for color matching, is the D65 fine for this? Pantone has further confused me by using M1 lighting for the color bridge guide, but M2 lighting without UV for the online color finder - do the Absolute series modules qualify as M1 lighting (the D50 version anyway)? 

First of all, our ABSOLUTE SERIES LED modules sound like a great option to give you an excellent "building block" for building your own light panel. The 99 CRI is an excellent fit for many color viewing and color-critical applications.

​Whether or not you will need a diffuser will depend on whether there will be any potential for glare. If, for example, you plan on shining the modules directly at the illumination subject, there should not be any issues. For more information, we would recommend our blog article here: https://www.waveformlighting.com/home-residential/aluminum-channels-for-led-strip-lights-are-they-worth-it-an-in-depth-look

​If you do decide that the aluminum channels and diffusers are indeed necessary, you may want to consider our flexible LED strip version of the ABSOLUTE SERIES as they will fit inside the aluminum channels without any issues.

Each module produces 800 lumens. It's a bit difficult to provide any recommendations as to whether this is sufficient or excessive for your needs, but you may want to take a look at our lumen estimation calculator, which you can find here:

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

​Alternatively, a useful rule of thumb is to remember that 800 lumens are approximately equal in brightness to a 60-watt incandescent bulb.

​Transitioning to our household lamp form factors, the NorthLux is not available in an E27 socket variant, so we would recommend our CENTRIC DAYLIGHT versions instead. For more information on E26 vs E27, you may want to reference our article here:

https://www.waveformlighting.com/home-residential/e26-vs-e27-bulbs-are-they-interchangeable

The CENTRIC DAYLIGHT versions also offer an excellent 95 CRI color rendering at 5000K and 6500K, either of which should work well for you. The only minor difference (as noted by their part number including or not including the letter "D") is that the NorthLux is calibrated to D50 and D65 color standards, which may be of interest to you.

The actual color rendering values will depend on the specific bulb. Our guaranteed values are 95+ and 80+ for CRI, respectively, but depending on the specific bulb, these values may fluctuate. CRI, for example, can be anywhere between 95 and 98.

Since you'll be using the lamps for digital arts (rather than printing and visual assessments) with monitors calibrated to D65, our 6500K or D65 product options sound like the best option for you.

Is there a recommended type of material for this, or will any type of translucent plastic do? Are there any materials that look appropriate but I should actively avoid them due to them compromising the CRI too much? If I use completely transparent clear plastic just for a protective 'lid' over the module, will this affect the color temperature or CRI at all? My gut says no on this last one, but thought it was worth checking in case there's something I'm not aware of.

Unfortunately, all materials will absorb and reflect a small portion of the light energy across the spectrum in slightly different ways. We generally recommend using polycarbonate, acrylic, or glass, as these materials generally alter the spectrum to the smallest extent. Some anecdotal testing on our end indicates that polycarbonate diffusers can affect the color temperature by 200-300K. CRI is generally not affected.

I was hoping you might be able to give me some quick advice on setting up the modules - I've made a basic diagram of my plan, but I don't have much experience with this sort of thing, so I was hoping you could take a quick look and see if it makes sense.

I've reviewed the drawing you kindly provided, and everything looks good and reasonable.

Hopefully, this makes sense, if not, let me know! I will most likely put 3 modules on one panel and 2 on a separate one, but I am making the basic assumption that even if I put all 5 on the same panel using the same power supply, it should be ok, as the power supply is 24v, 60W, 2.5A, which seems to cover the minimum requirements for 5 modules, plus a bit extra - is it ok?  

Yes, the power capacity appears to be perfectly fine for this installation. The only thing to be careful of would be to make sure that the wires used to connect the modules have sufficient thickness. Generally, if you're just connecting a single module, you should be fine with 20 AWG or thicker.

Is it okay to use an inline switch sold as a 12V switch, as long as the amp rating is high enough? I found some that say 2 amp max at 12VDC, and one that says suitable for 5-24V but doesn't mention amps... They're all very basic barrel jack connected on/off switches that look identical, but I've read conflicting information online about this issue, mostly regarding the possibility of arcing with higher voltage, so I thought I'd better ask even though most people say it's ok. I'm guessing the current that will go through the switch will only be the 420mA / 10W for a single module though, given how it will be set up.  

There should not be any significant safety issues here, but we would recommend checking with the switch manufacturer to ensure that operation at 24 volts would be permissible. I believe that both the arc voltage, as well as current ratings, would both be of concern here.

Not too bothered about having to replace the switches if they break, but I don't want anything bad to happen to the LED modules. And I'm assuming that connecting and disconnecting the modules via just unplugging any of the connecting wires between the individual module and PSU while it's all switched on is a bad idea? This sort of thing is generally frowned upon, hence my idea about adding inline switches for each module for some brightness control... Sorry if any of these are silly questions, I'm learning this on the fly! 

There should be no issues with the modules, as long as they are not suddenly flooded with voltage or current.

As for the A19 style bulbs, does the article you linked basically mean it's always unsafe to use E26 bulbs in an E27 socket, even when they are compatible with 240V AC?

That is our assessment based on the dimensions and input voltage levels.

Would it be safe to use a NorthLux E26 bulb with a B22 (bayonet socket) to an E26 adapter at 240V? (E27 to E26 doesn't seem to be a thing...) Given that the product page says it's compatible with 240V AC, I assume I wouldn't have to use a step-down transformer or anything?  

Yes, the product is compatible with global input voltages and will operate with 240 volts AC despite having an E26 base.

Do you know if NorthLux bulbs (the D50 version anyway) conform to the M1 lighting standard at all? 

Unfortunately, our D50 products do not conform to the MIUV metamerism requirement for UV fluorescence. As such, you will see our conformance is limited to ISO 3664:2000 and not any of the later standards.

Do the lights emit anything into the UV range at all, or are they closer to the M2 UV-excluded type lights in that respect? Doesn't help either that the bridge guide uses M1 standards and photoshop uses M2 when the paper the guides printed on is full of OBAs.

All of our products do not emit any UV (defined as < 400nm) except for our realUV products.

Except for our ABSOLUTE SERIES LED products, the LEDs are based on a royal blue 460 nm emitter with phosphor downconversion, so virtually no energy is emitted below 430 nm or so.

I saw the section about white rendering on the Absolute series product page, does this mean they can activate the OBAs in paper and textiles, at least somewhat? 

You are correct that the ABSOLUTE SERIES LED products do have some potential to excite OBAs to improve white rendering. This is due to the underlying emitter being based on a violet emitter which peaks at 420 nm. You'll notice, though, that this is still well within the visible range of the spectrum and does not produce enough ultraviolet energy to provide meaningful improvements to MIUV rendering.

One thing you may want to look into is the realUV LED strip or floodlights​ in combination with our existing visible wavelength range products to improve UV rendering. Unfortunately, we don't have any test data or full solutions here, but this may be worth experimenting with on your end.

Flicker-Free LED Vanity with Dimmer for 60fps Video

If I purchase and install 18 FilmGrade™ Flicker-Free A19 LED Bulb with a FilmGrade™ Flicker-Free LED Dimmer, will I have a Flicker-Free video filming experience? Can I use my existing bulbs and just replace the existing cheap dimmer I installed with your Flicker-Free LED Dimmer for any semblance of success, or do I need to buy the bulbs as well?

Our FilmGrade™ Flicker-Free LED Dimmer product is only designed to be used with low-voltage LED lighting, such as our LED light strips.

As such, we do not recommend using it with products such as the FilmGrade™ Flicker-Free A19 LED bulbs.

Further, the FilmGrade™ Flicker-Free A19 LED Bulb is not dimmable. Therefore, we discourage using this item with any dimmer products.

That being said, our LED light strip products could be an alternative for your space. These products, such as our FilmGrade™ WHITE LED Strip Lights, are dimmable, pair with the FilmGrade™ Flicker-Free LED Dimmer, and are available in many different color temperatures.

Do you have recommended dimmers that will cause LED lights to flicker at 40 hertz?

I am looking for something to plug LED lights into that will cause them to flicker at 40 hertz. Will any of your devices, such as adjustable LED dimmers, do that?

Unfortunately, we do not have any products that allow you to adjust the flicker frequency. You will likely want to consider a microcontroller solution such as an Arduino setup.

FilmGrade Flicker-Free LED Dimmer Specs and Wiring

1) What is the switching frequency? Your info suggests 25 kHz, but you have no spec for that on your product page.

2) Is +, -, or neither common to input and output? I am installing it in a fixed installation, where the number of available conductors is limited. Do I need to run both +/- output wires to the load, or can I run the switched output wire to the load, and tap off one of the input wires (whichever is common) as the other conductor?

To answer your questions:

1) The switching frequency for the product is 25 kHz.

2) The output uses a common positive, and the switching occurs on the ground channel. The article and graphic below may provide you with some additional insights on this:

How to wire and power a long LED strip run (100 ft+)

I am looking to install LED strip lights across a 100 ft section. How many power supplies do I need, and should I use 12 volts or 24 volts?

Our recommendation is to set up six separate LED strip runs of 16.4 ft each. We would recommend our 24 volt LED strip lights, and each of the 16.4 ft runs should be powered by a TRIAC dimmable power supply. All of the power supplies can be connected to a single wall-dimmer so that the entire 100 ft section can be controlled from a single dimmer switch.

If you're wondering why we need a separate power supply for each 16.4 ft run, see our article below which should provide some additional insights, as well as some third-party options:

Operating a TRIAC-dimmable LED power supply from wall outlet

Can a Triac-dimmable power supply such as the CENTRIC SERIES LED power supply be connected to a wall outlet and controlled by a wall-dimmer?

Electrically speaking, this could be accomplished. However, this would not be an advisable configuration from an electrical safety standpoint. This is because, in general, a wall dimmer should never be connected to a wall outlet.

Wall outlets are used for a wide range of non-lighting related electrical appliances. If a non-lighting product is inadvertently plugged in and "dimmed" from the wall-dimmer, there may be some catastrophic failures and/or safety issues that arise. For example, a microwave oven is most certainly not designed to be "dimmed" from a wall-dimmer, and could potentially lead to some serious issues.

As an alternative, we would recommend using an in-line PWM dimmer in conjunction with a plug-in power supply.
