How Can We Help?

UV-A LED Light Irradiance and Black Panel Temperature

I have a customer that wants to run a UV test on their product. Their requirements are 1) Black Panel: 60C 2) Air Temperature 38C 3) Humidity: 50% 4) Irradiance: 0.6W/m2. Do you have a product that will give me the irradiance and black panel temp I need?

Our 20-watt UV flood light may be a good fit for you here. The product has a measured irradiance of 650 µW/cm² or 6.5 W/m² at a distance of 12 inches. 

Please see below for additional information:

https://www.waveformlighting.com/photometrics/BP_7022.pdf

​We do not have any data on black panel temperature but believe that the product will remain well within the 60-degree C requirement. The product is rated for humid environments and the 50% rating should not be an issue.

UV-A LED Light for Curing Glue-On Metal to Glass

Which UV light is best for curing glue-on metal to glass? Should I use 365nm or 395 nm? 

While we do not have any specific data on cure rates including the glue-on product, our 365 nm wavelength is generally better suited for curing applications and should be a good option for you.

The product I am using is CRL UV adhesive, UV KLEBSTOFF, high viscosity. I am attaching metal jewels to glass containers and need to know if this is the correct UV light before I order additional lamps?

We did a quick search online but was unable to locate any specific UV requirements for the UV Klebstoff product. However, we do believe that our UV-A lamps are in the general range of wavelengths required for most curing applications and should work sufficiently for your needs.

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

Do you make UV-B lights that are 300-400 nm?

Do you guys happen to make UV-B lights that are 300-400 nm?

We do make several lights that are at the 365 nm wavelength, which falls within the wavelength range you specified below (300-400 nm). Please note, however, that these lamps are typically considered "UV-A" and not "UV-B".

​Please see below for one of our most popular UV-A lamps:

​

LED Bulb to cover the UV-A Light Spectrum

I need a bulb that can cover the UV-A light spectrum. I need it for my enlarger so it needs to be bulb size. Ideally, it would be the 365nm realUV but I don’t see that there are E26 bulbs or E26 LEDs for that. I think this bulb at 6500K may be as close as I’ll get but was wondering about the light spectrum it covered. 

While I completely understand the reason for the need for UV-A in a standard E26 bulb format, we do not have any products that would meet those requirements.

The 6500K bulb you linked to does not contain any ultraviolet energy.

​The closest option would be our UV flood light, which I have linked to below:

Black Light with Fluorescent and Blue Visible Light for Pool Setting

I want both a strong "black light" color pop with fluorescents, but also some nice "blue visible light" to accent a pool setting. The product likely needs to be waterproof or water-resistant at least as it will be mounted outside for about a week. Some illumination of the area would actually be nice but still want some good black light effect. Also, do you have a submersible pool light option?

Based on the details provided, we might recommend the 395nm realUV™ LED Flood Light product, as it would emit more visible light than the 365nm version while still offering fluorescence effects.

For more information regarding the differences between the two options, the below article from our website might prove to be useful.

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

However, please note that while these products have an IP65 rating, they are not designed to be submerged.

Do you have an RGB+W led light strip that is suitable for outdoor use?

While we do offer products such as the ColorSpace™ RGB Color Changing LED Strip Lights, these products are unfortunately not designed for outdoor use, or for installations where they may come into contact with water or moisture.

UV-A LED Light for Aging

I'm interested in an LED strip which can be used for accelerated life testing, preferably something that is close to the UVA-340 florescent lamps. 

While we do not have any specific guidance or test data, our UV-A LED strip lights could certainly be considered for ultraviolet exposure in simulating accelerated aging under certain lighting conditions.

Our 365 nm and 395 nm LED strip lights may be a good starting point for providing UV-A radiation output. I've provided the product link below.

​

Outdoor UV LED Blacklight Sign Lighting

I'm working on lighting up a music venue sign with blacklight LED strips. The strips will be under a metal awning. Do you have a UV blacklight, weatherproof, LED strip?

Although our UV LED strip lights would be a great fit for a backlight sign, they are unfortunately not waterproof so even for use under an awning, they would not be a good option for outdoor use.

​Our UV flood lights, however, are IP65 rated and can be used outdoors. I'm wondering if this might be a viable alternative product that you may want to consider.

​We've included the product link below for your reference:

Flicker-free Bulb for Color Rendition and Artwork

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

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

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

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

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

Are there any flicker-free floodlights?

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

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

Is your realUV Flood Light Sealed and NFPA33 Compliant?

I'd like to know more about your 395 nm flood light for a curing application. I need to install paint booths, and I'm interested in knowing if your lights are sealed and compliant with NFPA33. 

Our 395 nm UV flood lights are sealed and IP65 rated, but do not have an official NFPA33 test rating or data at this time.

UV LED Light for Cyanotype Printing Application

I have read several of your helpful articles but still have no idea which would be the best light for working with cyanotypes. (Cyanotypes are a type of cameraless photography where you contact print images and expose them either under the Sun or a UV light) I assume people have purchased these lights for this purpose before. Can you let me know if both NM types work or if one is superior for this particular use? 

While we have not done any internal tests or gathered any data to verify, we have indeed have numerous customers reach out regarding this application.

​We believe that the 365 nm wavelength works best for cyanotype printing applications. The 365 nm UV LED flood light is certainly a popular option. Please see below for the product link:

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

Can a UV Flood Light be made available with a VIS-blocking filter?

Can this be made available with a VIS-blocking filter per your UV flashlight?

We do have a new UV flood light model at 50 watts with the Blackout filter that is used on our flashlight.

Does the filter have an IR leak? (As do the Wratten 18A and the equivalents)?

We do believe that the filter does allow IR to pass through.

Therefore, depending on the sensitivity of your equipment, incorporating an additional IR filter may be required.

​We would imagine, however, that the infrared produced by the UV LED would be limited to the thermal radiation component only (as the LED chip itself heats up), as all of the radiometric output would be confined to the UV-A band.

UV Lights for Invisible UV Activated Paints

I am looking for the UV light that will activate invisible paints made by wildfire. Modern masters. What would you recommend for that and do you have a diagram of the angle for the lights? I am trying to calculate how to hide it in millwork. 

While we do not have any exact data or measurements for the Wildfire fluorescent paint products, our 365 nm UV LED lights will likely be a great fit for your needs.

I've included a link to our 365 nm UV LED flood lights, which I believe will be a nice option:

I've also included the irradiance pattern below, which can provide additional information on coverage at various mounting heights:

https://www.waveformlighting.com/photometrics/BP_7022.pdf

365 nm UV Lighting for Imaging Failure/Cracks

I'm looking to know if you might have any 365 nm UV lighting that could be of assistance for the detection of cracks/failures when imaging (using a Canon camera set for UV conditions). 

We, unfortunately, do not have any test data or literature for the application you mention, but we do expect that our UV LED products are well suited for installations that require the use of UV to visually inspect and fluorescence effects. In particular, we would recommend our 365 nm version over the 395 nm version, as this provides additional visual contrast of fluorescence effects without as much visible, purple light.

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

realUV™ LED Flood Light for a Music Studio Installation

I'm trying to find a way to incorporate a black light in a music studio, since the walls and ceilings are upholstered in a sound-absorbing fabric I cannot fix anything to these surfaces. I am looking for a pure black light to highlight a piece of art - a painting with fluorescent paints- and this is going to be placed inside a music studio. As there are live recordings taking place here, the light must be silent. For that reason, I would prefer that it is as small as possible- for aesthetic reasons! 

It’s also important that the light doesn’t omit blue light, it needs to be pure. Do you have any suggestions/advice for me? Looking at the website “realUV LED flood light seems to be the best option.

Based on the information provided, it does seem that our 365nm realUV™ LED Flood Light product could be a great option for your studio.

We can recommend the realUV™ LED Flood Light product, which should not emit any noise while operating.

I also wonder if it gets quite hot when in use. I would like to build a cubic wooden box and have the light placed inside so that it is not so visible. It could be A) a box with only walls or B) a box with walls and a base so that all sides are encased except the side omitting the light. Would this be possible?

This product would require a moderate amount of airflow so that the small amount of heat generated by the light can escape. Without the ability to dissipate heat, the components within the product can encounter issues. 

What is the irradiance of UV-A fluorescent bulbs versus distance?

I enjoyed reading through your webpage "Understanding UV-A Irradiance, and Requirements for Various Applications."I'm trying to figure out the (approximate) irradiance values at different distances. I've been given two values for a 365nm fluorescent bulb fixture: 1,700 uW/cm2 @ 5 inches and 800 uW/cm2 @ 12 inches. I've tried applying the Inverse Square Law but this isn't working for me. 

We would expect that the inverse square law would indeed apply for a fluorescent lamp as well, but there may of course be some variations depending on the lamp length or other factors.

I would recommend reaching out to the manufacturer of the lamp for additional details, or purchase a UV meter to empirically determine irradiance values.

LED Light Recommendation for Cyanotype Exposure

I am looking for a light source for a photographic enlarger that will work to expose cyanotype prints. Hopefully it would be able to fit a normal sized light bulb socket and be the size of a standard light bulb to fit inside the enlarger housing. What light might work for this application?

While we do not have any official support for cyanotype applications, our understanding is that a 365 nm wavelength UV blacklight would work best.

​While we don't have a screw-in solution, our UV flood light will likely be a great, straightforward product that can be mounted almost anywhere, and simply plugs in without assembly required. Below is the product link:

LED Lighting for Finding Pet Stains

I'm looking for a good light to find pet stains in the basement apartment that I rent out. Which level of light, 365 or 395, would I need? And would the flood light work well for that? Or is there a better product option?

We generally recommend 365 nm for this application, as this wavelength provides stronger fluorescence and therefore more visible contrast of the stains. For additional insights on comparing 365 nm with 395 nm, the following article may be helpful:

https://www.waveformlighting.com/tech/what-is-the-difference-between-365-nm-and-395-nm-uv-led-lights

​The flood light can be a nice option, but for a portable option, our UV flashlight may be an even better option​. Please see below for the product link:

Does your realUV LED Floodlight properly expose a standard size silkscreen?

Could you tell me if your 20W 395nm UV-led flood light will properly expose a standard size 20"x24" silkscreen? If so, could you tell me what brand of emulsion is for solvent-based or plastisol-type inks? I can't find any info on your site that says it will work or won't work. Are the 395nm UV-led strips effective in the same application? Approximately how far apart should the strips be and approximately how far away from the screen?

Unfortunately, we do not have any test or reference data for silkscreen exposure applications. Several customers who have used our products have reported success using the 365 nm wavelength variant of our LED strip lights. The exact requirements are likely to depend on the emulsion product and variations among manufacturers and formulations. If you have any additional information on peak wavelength sensitivities or irradiance requirements, we may be able to provide some additional guidance here.

​For your reference, below is an example of a customer who successfully used the 365 nm UV LED strips to produce a similar solution:

We do apologize that we do not have any readily available literature or data on silkscreen UV applications. As we enter the new year we do hope to be able to provide additional information for this specific application as we have seen quite a bit of interest in this area.

In the meantime, we would perhaps recommend testing and taking advantage of our free returns policy. If for whatever reason you find that the LED strips are not going to work for your project, we would be more than happy to pay for return shipping and offer a full refund. All we ask is for you to keep the LED strips in their original condition, meaning that the adhesive liner must not be removed and that the LED strips must not be cut into any shorter sections or otherwise altered.

Do you have a high CRI dimmable R20 Flood Lights?

I'm an artist replacing my incandescents with LED in my studio. An artist friend recommended Waveform. My track lights are R20 size. I'd like high CRI floods, and I'm thinking that 4000K would be a good balance between the warmth of the 2700K and the coolness of 5000K. They need to be dimmable. I'm hoping you have something, but I wasn't able to find this on your website.

While we currently do not offer R20 bulb sizes at this time, we would be glad to let my product team know about your interest in the product for future consideration.

365 nm vs 395 nm UV LED Strip Lights

Our business is platinum photographic printing. I have 10 meters of 395nm strip. I am building an exposure unit with those. I believe the sensitive area for a pt. print is around 300 to 400 nm and glass is about 300 nm cut off. The glass is needed. Is there an advantage to using 365 nm UV strips? How much, if any, can voltage boost output -- considering air cooling? is there an advantage to using UV floods? 

We don't have any official support for exposure unit installations, but other customers have reported much success using our UV LED strip lights for screen printing applications.

​We believe that the 365 nm may be a more effective wavelength given that this wavelength level is a "deeper" UV-A wavelength that may be a closer overlap with the sensitivity range of various emulsion materials. We do not believe that the 300 nm cut-off glass will be an issue.

​The products are rated at 12 volts only, and over-drive is not supported and will likely lead to premature failure, even with sufficient cooling.

​The UV floods can also be an option, though achieving uniformity may be a bit more challenging. For example, please see our irradiance charts for the UV flood light below:

https://www.waveformlighting.com/photometrics/BP_7022.pdf

UV floodlights or LEDS for Fluorescent Wood Pieces?

I've got a 12-foot-tall cedar log standing in my garage. I've inlaid several pieces of very fluorescent wood into it. I don't know which would highlight this the best, the LEDs or the floodlights. 

Our realUV LED lights sound like a great option to bring out the fluorescence effects from your fluorescent wood pieces. We would generally recommend the 365 nm option, as this version would produce less visible light but stronger fluorescence effects, which would produce a nice level of contrast for your installation.

​Please see below for the product link:

Do you have a UV 365 nm flood light that will meet a 1000 mW/cm2 minimum of 14 inches?

Do you have a UV 365 nm flood light that will meet a 1000 mW/cm2 minimum of 14 inches? Can I achieve this using multiple LED UV 365nm strip rows? 

I've just reviewed our UV irradiance pattern for our UV flood light, and it looks like we are at approximately 0.65 mW/cm2 at 12 inches away. As such, we are more than 3 orders of magnitude below your required 1000 mW/cm2 and we would therefore recommend a different solution for your needs.

​

Our UV LED strip lights are at similar irradiance levels (0.23 mW/cm2) so even if you were to use multiple rows, you will, unfortunately, fall well short of the requirements.

365nm UV LED light for Outdoor Applications

We are working on a project that requires 365nm wavelength in an outdoor application. We have tried other lights that have failed after a short time exposed to our environments. 

Our 365 nm UV floodlights sound like they may be the perfect fit for your application. The product has an IP65 rating and is suitable for outdoor use:

The product has a 15,000-lifetime rating and we also offer a 3-year product warranty, so should there be any reliability issues during this time, we will gladly send a replacement unit.

UV Flood Lighting for Indoor Stadium

I have a 5300 sq ft area that I’m looking to conduct parties, and games (UV soccer, etc.) in UV flood light. Could you advise on what type of systems I might need and whether you are in a position to ship them to India?

It sounds like our realUV LED lamps would be a great fit for your party and game space.

Our UV flood lamps might be a good starting point, with each lamp capable of covering approximately 100 square feet. Please see below for the product page:

We do ship our products to India via UPS / DHL, although import taxes, documentation and procedures would need to be handled on your end.

realUV LED Lights and Bird Anti-Collision Glass

Last year I built a new modern design house for myself and my wife which has many 10 ft tall by 5 ft wide windows. Bird collisions are now a problem and I do care about our feathered friends. I am trying to find bird anti-collision applications that have a vetted high degree of efficiency but yet are relatively unnoticeable. I have applied clear UV liquid in 2 x 4 patterns on the exterior of the glass, however I am still witnessing bird strikes and the UV liquid washes off in a few spots of rain and must be re-applied. So please, a few questions; 

Do you know of a realUV LED application as a shadow caster on large insulated residential windows specifically for bird anti-collision? The “UV shadow caster” illustration has the 385 NM UV LEDs in a canted (45-degree?) wood trim at the interior window glass frame. 

Do you think that a realUV Flood Light might work if it was aimed from the exterior on a large window? If the realUV 365 nm flood is invisible to the human eye, it might possibly be an economical solution. 

I read your cautionary note on exposure of the human eye to UV light. So in the end, realUV light might work to invisibly illuminate window glass so that birds will avoid it, but at what cost to the vision health of the human occupants?

We have checked on our end, but this is the first time we have worked with any customers on a solution for bird collisions using our UV LED products. As such, our support will likely be limited to product-related technical information as well as practical guidance, but we would nonetheless be more than happy to assist to the best of our ability.

It looks like our realUV LED strip lights would be a great option that would replicate the 385 nm UV LED strip lights used in the shadow caster installation. We do believe that the 365 nm wavelength option would perform just as well, if not better than, the the 385 nm wavelength. (For further reference, please see our article comparing 365 nm to 395 nm).

We must admit that we're still not clear on the mechanism of the UV shadow caster. Specifically, what is the "shadow" being cast and how does the UV interact with the glazing to create such shadows? What is the glazing material and what is the desired effect in terms of making it visible (or visible exclusively to birds) under the UV?

Most birds have twice the UV vision perception of the human eye. The concept is that flooding the surface of the glass with UV light will appear to birds as a virtual, near solid barrier. 

I have been in touch with an eye doctor regarding her opinion about being substantially exposed to UVA light in the 365 NM and 405 NM spectrum on a daily basis. The doctor’s opinion is that UVA exposure is not harmless.  

Regarding the “UV caster” with the above said, I am now inclined to explore utilizing the UVA 365 NM flood lights aimed at the window glass in combination with UV filtering applied window film to block the UV light from entering the interior.

While we can't speak to the efficacy of the specific UV caster product, we do now understand that taking advantage of the differences between birds and humans in terms of their wavelength sensitivities, there may be an opportunity to develop a solution that benefits birds without creating a significant hindrance to humans.

As far as UV safety is concerned, it’s a bit difficult for us to provide assurances and guarantees regarding the safe use of ultraviolet LED products, as each installation and application can vary significantly, so we recommend consulting a UV safety expert if you have any further concerns.

Both the 365 nm and 395 nm wavelengths fall under the UV-A wavelength range, which is a weaker form of ultraviolet radiation that is found in natural daylight so there are fewer concerns than other ultraviolet products that fall under the UV-B or UV-C wavelength ranges, for example.

That being said, below are some general safety guidelines that we would recommend following:

UV-A realUV LED Blacklights for Body Paint Application

I am a professional artist that works in multiple medians. I recently started looking into UV body paint and will use Krylon day glow UV body paint. Will your black lights work for this right now? 

We're happy to confirm that our UV-A realUV™ LED products, such as the realUV™ LED Strip Lights and realUV™ LED Flood Light products, work well with fluorescent paints.

If it proves to be useful, here is a link to a blog post from our website, which explains the ultraviolet blacklight products in further detail: https://www.waveformlighting.com/tech/top-4-things-to-consider-before-buying-uv-blacklights

realUV LED Flood Lights for (20x44ft) Pickleball Court Installation

What should I get to light up a pickleball court? Do they have solar? We do have four light poles. Will the flood light work? We want the balls to light up at night.

Our realUV LED flood lights sound like they may be a good fit for your installation!​Each flood light should be sufficient to cover an approximately 10 x 10 ft area, so you may need to strategically place up to 8 of these lamps across the court to ensure full coverage. Perhaps each of the four light poles could have two lamps mounted on them, pointed in perpendicular directions to cover the court fully.

Our lamps are not designed to connect directly to any solar systems, as they operate on 120 volts AC through a standard socket.

We don't have any test data on the fluorescence effects for pickleball balls in particular, so we would perhaps recommend performing a quick test before moving forward with any installations. We do offer a 30 day free returns policy, so that could definitely be something worth taking advantage of.

UV Light Bulbs in E26 Base to Restore Yellow Plastic to Clear

I know this sounds weird but I have been scouring the www to find ways to restore yellowed plastic sections of a tube-style bird feeder that is no longer made. It seems like soaking in hydrogen peroxide or slathering the plastic with a beauty salon product containing peroxide and then exposed to UV light will do the trick. Sun is at a premium these days here so I am wondering if I can find the right UV bulb (standard base) I can use in a small, otherwise dark room. Can you suggest something?

Unfortunately, we do not have any UV bulbs in a standard E26 base. The easiest alternative option would be our flood lights, which can plug into a standard wall outlet. Please see below:

Do you have BR30 bulbs in 2700K Color Temperature?

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

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

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

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

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

UV LED black lights with 500 µW/cm²

I am searching for LED UV Black lights with a 365 nm UV intensity of > 500 µW/cm² at a distance of 12". Which products of yours should I use?

Based on your UV irradiance requirements, we believe that our 365 nm 20W UV flood lights might be a great solution for you.

Our measurements (see irradiance charts here) indicate that at a 12" distance from the lamp, we have an irradiance value of 650 µW/cm². This will allow you to reach the UV intensity requirement of > 500 uW/cm2.

Do keep in mind that the 650 µW/cm² value represents the highest intensity point, directly center and perpendicular to the lamp. As you move away from this center point, the UV intensity will begin to diminish. The irradiance charts should help with additional information on the extent of this attenuation.

Depending on the total surface area you need to cover with > 500 µW/cm², you may want to install multiple lamps. The irradiance values for a given point can be directly summed across the multiple lamps' individual irradiance values.

realUV LED strip lights for screen printing

I’m making my own DIY exposure unit using your LED strip lights to cure the emulsion on my screens for printing onto clothing material. 395 nm seems to be the most recommended for this application, but I'm wondering if your 365 nm version would be a better alternative?

At this time, we, unfortunately, do not have any definitive answers as to whether 365 nm or 395 nm is the more effective wavelength option for screen printing applications. Our customers have actually reported success with both wavelengths, but we aren't able to say with confidence whether one works better than the other.

Variations in emulsion materials between manufacturers and products can result in different sensitivities to different wavelengths. We do hope to conduct some tests internally for specific products in the near future, as we do indeed have numerous customers who are also interested in using our products for this application.

Our suggestion would be to perhaps consider the 395 nm first as it is at a lower price point. On the other hand, the 365 nm is generally a wavelength that is better suited for chemical curing processes, so that can also be a potential option for you to consider as well.

Finally, for assembly, this illustration below may be helpful in showing you how the sections can be joined together:

Do you sell the UV COB that is in the flood light?

I was wondering if you just sell the UV COB that is in the flood light? Also, do you sell the driver as well? I’m mainly looking for the UV LED COB.

Unfortunately, we do not offer the individual lamp components separately.
