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. 

365nm Blacklight for Ascertaining the Age Period of American Brilliant Cut Glass

I am looking for a 365nm black light to be used in ascertaining the age period of American Brilliant Cut Glass.

This was produced in America circa 1870-1920. The preponderance of American-made lead crystal included manganese, in contrast to European-made glass. Manganese will fluoresce under 365nm black light.

The light source should not produce other wavelengths that would interfere with observing fluorescence.

If the sample fluoresces, it will be a strong indicator that the glass is genuine from the period. Do you have any items to suggest? I am thinking the 365nm flood might be good.

Based on the details provided, it appears that the 365nm realUV™ LED Flood Light could be a great fit for your installation purposes. We have attached a link to the product's photometric report and UV irradiance patterns below, in the hopes that they prove to be helpful. 

Photometric Report

UV Irradiance Pattern

If you would like to try out this product for your fluorescent testing, please feel free to take advantage of our 30-day return policy. We will gladly provide prepaid return labels for any unneeded items from domestic orders. 

realUV™ LED Flood Light for Burning Screens

I'm interested in buying a UV LED flood light for burning smaller than 8.5 x 11 screens in screen printing. Is 395nm good for this purpose? Where is it made? 

Generally speaking, we like to recommend the 365nm option for any installations where stronger fluorescence effects are desired such as black light paints or other displays as the output is much further from the visible spectrum of light than the 395nm option. 

​That being said, some printing methods which utilize ultraviolet light, such as cyanotypes, often require a specific nanometer range for optimal effect. If your installation requires an ultraviolet light source closer to the 395nm point, we would recommend utilizing that option. 

As a further note, please feel free to try both options and take advantage of our 30-day return policy. We will gladly provide prepaid return labels for any unneeded items from domestic orders within that window upon request. As a final note, we can confirm that our realUV™ LED Flood Lights are manufactured in China. 

realUV Floodlight for UVIVF Photography

I was reading about the 365nm floodlight option that you guys have. My objective is to use it for UV-IVF photography, but the description says it spills some visible light. Is that visible light spill to 

overwhelming for it to render UVIVF useless? I saw that it required an additional visible light filter to be added in order to make some decent UVIVF photography. So my question is, will my ZWB1 UG11 filter be enough to make this kind of UVIVF photography possible?

As we have not utilized the ZWB1 UG11 in our internal testing of the realUV products, it is unfortunately difficult to say whether the visible light would spill into the frame. That being said, so long as the filter is able to block the transmission of the visible spectrum from 400nm upward, we would imagine that no visible light would be able to pass through the filter. 

In the hopes that it proves to be helpful for your installation and purchase planning, we have provided a link for the photometric report below:

395 nm Photometric Report

365 nm Photometric Report

UV-A Light to Replicate Sun Bleaching and Polymerization Effects

Linseed oil for artists' oils is often left outside for bleaching and pre-polymerization effects. I'm curious if a UV-A lamp would do the same in a clear container inside. A "curing lamp" for linseed paint is sold by a company whose "Light output is filtered to minimize hazards from short and medium wave UV and bright visible light." It's called a UV400 curing lamp. I'm assuming it's a wide spectrum UV lamp with a filter to block B and C and allow A. Correct? 

I'm trying to find a way to replicate the sun bleaching and polymerization effects in a container, either glass or clear plastic, with quantities of 5–50 gallons. Shot in the dark reaching out, but perhaps you have some recommendations for UV-appropriate bulbs. 

As our expertise is primarily limited to our own catalog, we unfortunately do not have any information regarding the ultraviolet filtering methods used by the third-party manufacturer. We do sincerely apologize for any impact this may have on your installation planning. 

That being said, based on the details provided, you may also be interested in our 365nm realUV™ LED Strip Lights and 365nm realUV™ LED Flood Lights. We find that the 365nm option provides the greatest fluorescent effect against targets compared to the 395nm option. As can be noted within the photometric reports, our products emit a narrow band of ultraviolet output without requiring filtering. 

As a final note, it might be helpful to know that our LED Strip Light products are not IP rated for protection against the elements, such as contact with moisture or condensation. As such, any contact will cause electrical hazards and void the product warranty. 

Does the realUV LED Flood Light emit any visible light when turned on?

I work in a lab that will require UV lights for our next trials. My PI is interested in this product: realUV™ LED Flood Light and has the following questions: 1) When turned on, does it emit any visible light? We need something that doesn't emit any visible light (not even mild violet); (2) Do they have any products with lower UV wavelengths (ie. 340 nm) 

Though it is further from the visible wavelength than the 395nm option, we can confirm that a minute quantity of visible light is emitted by the 365nm version during operation. 

Beyond the 365nm and 395nm options, we also offer the 270nm cleanUV™ UV-C LED Strip Light. Unfortunately, we do not currently offer an ultraviolet option in the 340nm range. 

Can I remove the hex bolts of the mounting bracket of the LED floodlight and screw them back in after attaching the mounting bracket?

I bought 2 of your 20W UV floodlights. Can I remove the hex bolts of the mounting bracket and screw them back in after attaching the mounting bracket? Do these bolts screw into the threaded metal rather than hex nuts that will fall after I unscrew hex bolts?

As the hex bolts on the realUV™ LED Flood Light mounting bracket is not intended for removal, please note that doing so would be a non-supported product modification. 

That being said, as we believe that the metal holes used by the hex bolts on the bracket are threaded, the proposed installation should be feasible. 

UV LED Light for Rally Car Lighting

I build and race rally cars where we often have night stages where the codriver needs to read notes during the race. I thought blacklight would be a good way to illuminate the notes while not flooding the cockpit with light that would distract the driver. A little advice on our specific needs would be much appreciated and we'd love to use your lights in both our car as well as our customers cars. 

As a starting point, it might be helpful to know that the 365nm and 395nm versions of our ultraviolet products offer different benefits. 

Where the 395nm is closer to the 400nm visible spectrum cutoff point, it will offer a moderate amount of visible purple illumination. Contrastingly, as the 365nm option is further from the visible spectrum it will offer a greater fluorescent effect upon targets that react to ultraviolet light. 

UV LED lights for Finding Dog and Cat Urine on the Floor

Can you tell me which of your UV LED lights would be the best for finding Dog or cat urine on Floor. No carpet in home. 

Based on the details provided, we would likely recommend the 365nm realUV™ LED Flashlight with BLACKOUT™ Filter Technology. 

As alternative options, you may be interested in the realUV™ LED Flood Lights and realUV™ LED Strip Lights products.

The LED Strip Lights would require an additional power supply for operation, such as our FilmGrade™ DC Power Supply for LED Strip or in-wall TRIAC Dimmable Power Supply, and can also be paired with in-line or in-wall dimmers. 

I do like the price of the Strip much more than the very first option you gave me, however, the power supply is more expensive than the strip. Is that power supply the only option to power the strip? If so, I understand and will order it, but just wondering if it takes batteries?

Although we do not have any batteries that we could recommend at this time, there may be third-party plug-in power supplies available elsewhere that would be compatible with the realUV™ LED Strip Lights. 

In the hopes that it proves to be helpful, we have attached a link to the product specification report which lists the power requirements. So long as the power supply (or battery) is able to afford 4.5 watts per foot of 12V power at 400 mA per foot, the products should be compatible. 

LED Lighting to Illuminate a Space of 10,000 sq ft in Black Light.

I'm looking to illuminate a space of 10,000 sq ft in black light. We have black light-reactive inflatables that I am trying to light throughout this space. 

Based on the details provided, we would likely recommend our realUV™ LED Flood Light product. 

If you have a specific illumination target for your installation, please let us know and we would be happy to recommend an order quantity that could meet the target. As you will note, the ultraviolet output decreases the further the targets are from the light source. 

With the hope that it proves to be helpful in the interim, I have attached a link to the product UV Irradiance Pattern, which charts the mw/cm2 output of the realUV™ LED Flood Light. 

We might also recommend ordering a single realUV™ LED Flood Light for your installation before submitting your full order so that tests can be performed to determine whether the output is sufficient for providing a fluorescent effect upon the targets below. 

Why the tree branch lit up when exposed to UV light?

I had an old tree branch that was on the table, a party UV light was on, and the cuts of the branch lit up like a day-glow poster only white. Why is that?

Many materials such as minerals, marine life, and terrestrial life are naturally fluorescent. These naturally fluorescent products will respond to ultraviolet light differently than non-fluorescent items would​.

For example, some of our customers utilize our realUV™ LED Flashlight with BLACKOUT™ Filter Technology for nighttime scorpion photography or yooper-light stone hunting, which are both naturally fluorescent. 

What is the expected life of 365nm realUV™ LED Flood Light?

I am interested if you have any info on the expected life and also in our application if we will need to turn in on/off roughly every 30 seconds. Will the light be able to handle this?

Based on the details provided, it seems possible that routinely oscillated power states might put undue strain on the internal power supply. 

If you would like to place a small order containing the realUV™ LED Flood Light to test in your installation, we would be happy to receive any information regarding how well the product operated. 

In the interim, we can confirm that the realUV™ LED Flood Light has a 3-year warranty for typical operation. 

395 nm UV LED recommendation for 54” x 84” surface area

I have some questions regarding UV LED and what products would be best suited to accommodate some specific parameters.

I would like to know what your recommendation would be to cover a 54” x 84” surface area with 395nm LED UV light with around 17-18 mW/cm2 light intensity. Is that something you could help with?

Based on my review of the UV Irradiance Pattern for the 395nm realUV™ LED Strip Lights, it appears that targets as far as 8 feet away from the light source would receive 16-18μW/cm2. This document lists 365nm, though the measured output is identical across both 365nm and 395nm. 

This product can also be paired with a dimmer such as our FilmGrade™ Flicker-Free LED Dimmer or a 12V TRIAC Dimmable Power Supply, if more granular control of the output is required. 

While we offer both the realUV™ LED Strip Lights and realUV™ LED Flood Light, we would likely recommend the former for evenly dispersed illumination across the entire work surface.​

It might also be useful to know that polycarbonate materials often found in diffusion panels of light strip channels will naturally filter ultraviolet output. As such, we would not recommend using those products if the ultraviolet output is desired unless the diffusion panel is removed. 

UV LED Lights for Glowing Pickleball Event on Tennis Courts

We are glowing in the dark Pickleball event on 2 tennis courts. I plan on having some cheaper led 390-400 nm lights to promise some purple light because the goal is Pickleball and not just glow-in-the-dark. Have to be able to see other players and obstacles. I want to use your lights to assist with the glow. This area is fairly large. Do you have one that will work with a 30-foot throw?

Based on the details provided, it appears that the 365nm realUV™ LED Flood Light would be the best fit for your installation among the items in our catalog. Though our LED strip lights are also available in the 365nm and 395nm versions, they are not suitable for outdoor installations where they may come in contact with the elements. 

That said, based on my review of the product floodlight UV Irradiance Pattern, it appears that there would be a fairly large output drop beyond a 9 ft distance, which may mean that it is unfortunately not the best fit for your pickleball courts.

As such, we might encourage you to purchase a single unit to test that the output is able to fill the 30-foot distance required. We would be happy to provide you with a prepaid return label within 30 days of purchase if the floodlights wind up not being the right fit. 

UV LED Light Option for Reactive Collectibles

I have an 8-wide by 6-foot tall shelving unit full of “black light” reactive collectibles, and I want to illuminate every possible inch of this with the “brightest” UV Light so that all of my collectibles have the strongest glow possible. Could you recommend the proper type of lighting fixture? I’m torn between a wall washer and a flood light.

Based on the details provided, we would likely recommend the 365nm realUV™ LED Flood Light, as the focused output may allow for a superior effect upon the targets than the downward-cast and dispersed wall washing method, depending on the orientation.

For visualizing the difference in output between the realUV™ LED Flood Light and the realUV™ LED Strip Lights, we have attached links to each product’s UV Irradiance Patterns below. 

By reviewing these documents, you will note both the comparative scope of the output as well as the gradual reduction of microwatts per square centimeter. Hopefully, this helps visualize the effect that each would have on your collectibles.

realUV™ LED Flood Light - UV Irradiance Pattern 

realUV™ LED Strip Lights - UV Irradiance Pattern 

When considering the 395nm and 365nm options it might be helpful to know that the 365nm option can provide a greater fluorescent effect on targets, as the output is further from the visible spectrum than the 395nm option.

How far away would you suggest mounting the light? As well as from what direction?

Based on our review of the LED Floor Light UV Irradiance Pattern, we would suspect that the light would function best at 2-3 feet from the target to avoid reduced output that further distances may result in.

To wash the shelf contents evenly, we would recommend installing the food light in front of and angled towards the shelf. This could be accomplished by installing the light on the ceiling using the metal mounting bracket. 

​If you would prefer evenly-distributed light using in-shelf lighting, then you may want to consider the realUV™ LED Strip Lights and aluminum channels as an option for installing lighting within your shelf. We have attached a LayoutMap below for an installation that utilizes connected segments of the ultraviolet LED Strip Light products, if that is helpful for visualizing the installation.

UV lighting to Illuminate the Target

I am developing a product that needs to illuminate the target. The target must glow in the dark. Can you help?

For installations where the optimal fluorescent effect is desired, we usually recommend the 365nm version of our realUV™ ultraviolet products. We have attached a link to a blog post regarding the topic below, which we hope is helpful for your installation planning. 

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

I have a couple of questions.

-What is the distance of the radiation of the 365 nm strip of light?

-We want to paint a narrow strip in the vertical direction and illuminate a fluorescent paint. Can we mask the signal as we would visibly light to produce a vertical column of UV irradiation?

-I assume not of this will work in sunlight conditions correct? How about overcast weather? Rain?

We have attached a link to the product’s UV Irradiance Chart below, which we hope is helpful for your installation planning. 

realUV™ LED Strip Lights - UV Irradiance Pattern

We unfortunately do not have any materials available which could be used to limit the transmission of product output, though it might be helpful to know that the 365nm version of the product will only produce a very minute amount of visible light. 

If you would alternatively like to physically block some portion of the ultraviolet light, we can confirm that most polycarbonate and other materials will naturally block ultraviolet output. 

As a final note, the fluorescence effect may be difficult or impossible to perceive due to the lack of contrast between it and the natural sunlight.

Does your UV Flood Light generate extreme heat during operation?

I am trying to get information to be able to accurately purchase lighting for our Puppet Ministry. I need 365nm so looking at the floodlights. They will be permanently mounted to our ceiling. Do they get hot? I may need 2 but think of trying 1 first to see if the "throw" & effects are appropriate. 

For installations where the optimal fluorescent effect is preferred, we recommend the 365nm option that you have referenced. We can further confirm that these products are not expected to generate an inordinate amount of heat during operation, and have attached a link to the realUV™ LED Flood Light UV Irradiance Pattern document which we hope is helpful. 

​It might be helpful to know that we recommend safety precautions with any installations that utilize our ultraviolet products, such as the realUV™ LED Flood Light. 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:

What frequency of light do your UV LED Flood lights operate at?

I am running a UV crayon grade mark reader. It is an enclosed cabinet with a video camera feed that reads fluorescent crayon marks that are manually put on the boards to determine lumber grade and trim marks. I am currently using 2 "UV" LED flood lights, but they emit far too much visible violet light. My software needs to pick up only the fluorescence of the crayon marks so this is an ongoing problem. What frequency of light do your LED lights operate at? I have control over the shutter speed of my video feed but have noticed in the past that the wrong frequency will cause the fluorescent brightness to fade in and out. 

While we can confirm that our realUV™ LED Flood Lights operate at 50-60Hz, it would be helpful for our troubleshooting to know whether your installation utilizes the 395nm or 365nm version of the product. 

For reference, the 365nm version will not emit nearly as much visible output as the 395nm, as it is further from the visible spectrum. This version of the product is able to produce the greatest fluorescent effect upon targeted subjects, which is why we would likely recommend changing to the 365nm option if not already in use. We have attached a blog post regarding the topic below: 

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

BlackLights for Research and Oil Paintings

Wonder what are good black lights - to use to study and research oil paintings? And where to purchase one? 

We can confirm that we sell many ultraviolet products that could be a match for your oil painting research. 

While most of our ultraviolet products are available in two versions, (395nm and 365nm), we find that the 365nm versions are able to produce the greatest fluorescent effect upon targets. This is due to the fact that the output falls almost entirely outside of the visible spectrum. 

For your installation, we might recommend either the 365nm realUV™ LED Flashlight with BLACKOUT™ Filter Technology, or the 365nm realUV™ LED Flood Light. 

While the realUV flashlight can be valuable for quick ultraviolet output or spot-checking, the realUV floodlights can be securely installed using the mounting bracket and powered via DC power. 

365nm UV LED Light for Curio Cabinet

I’m lighting a curio cabinet that is 6’ tall 28” wide and 12” deep for a uranium glass collection. Would I be better suited to use two one-meter strips of your LED product or your 20w flood light down firing into the case?

Given the dimensions of the curio cabinet, we might recommend installing several strips of the realUV™ LED Strip Lights within (or underneath) the individual shelves, to provide uniform distribution of ultraviolet output. 

While the realUV™ LED Flood Light could also be a good option, the output might be reduced when transmitting through each shelf and each item upon the shelves, which may result in providing only minimal fluorescent effect to the items on the lowest shelf. 

While both products are available in 365nm and 395nm, we typically recommend the 365nm option for the greatest fluorescent effect upon targeted subjects. 

We have also attached a LayoutMap below for installations using segmented realUV™ LED Strip Lights connected to a single power supply, which we do hope proves to be helpful. 

LayoutMaps™ - LED Strip Light Layout 7021_4C

Can I buy a filter or shield for the 365 nm realUV LED light?

I'm using this light I bought from you to show off my glow-in-the-dark artwork at live art shows, and I want to make sure little children or nobody gets hurt from the radiation or from the light in any way. I thought there was a "filter" of some sort on the light itself. but is there a way I can make this light safer so it doesn't hurt anyone's eyes or skin at these shows? The last thing I want to do is have anyone be hurt at my art show.

Generally speaking, 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 than 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:

As an additional note, we can confirm that while the realUV™ LED Flood Lights uses a clear polycarbonate lens, this lens is not designed to block the transmission of ultraviolet output. You may be able to locate a filter from B&H Photo, though please note that any ultraviolet-blocking filters will likely affect the fluorescent effect upon the subjects.

What is the warm up time of the BR30 bulb?

We have a set of BR30 lights that we use for important experiments. We would like to know the warm-up time for these lights after which the light intensity is stable. Please reply as soon as you can. 

Unlike traditional incandescent lightbulbs or fluorescent tube lights, our LED lightbulbs are not expected to have any warmup time and should provide optimal output without delay. 

We are also using your UV floodlights at 395 nm. Do they also not have any warm-up time? It’ll be great if they don’t.

We can confirm that our realUV™ LED Flood Lights are not expected to display any warm-up time delays and should emit full output upon startup. 

LED Strip Lights for PickerBall, lines, and nets.

We are making lighted PICKLEBALLS and need glow strips to light up the lines & nets. Can you help us? Also, we need small U. V. flashlights with 21 or more LEDs to light up our newly lit golf balls. 

​We currently offer LED strip lights, flood lights, and a flashlight that all feature 365 nm UV wavelength output. We've included product links below:

Depending on which of these form factors and lamp types will be practical for your installation location (please also advise if waterproofing is necessary) our product options would also correspondingly need to be adjusted.

How long does the strips stay lit? 

The LED strip lights have a 3-year warranty and an expected lifetime of 54k hours.

Will the adhesive be strong enough to adhere to the court? 

The LED strips utilize 3M VHB industrial-grade adhesive so there should not be any issues with reliability over time. (This is the same material used to mount glass panels in skyscrapers!)

Do keep in mind that the LED strips are not waterproof - I am assuming that these courts are strictly indoors.

UV LED Replacement Bulb for Screen Printing Machine

I have a screen printing machine that I need to get a replacement bulb for. The original is JP120V1KW it also has FCM on the label. Would you guys be able to reproduce the light bulb with the real UV LED technology? I bought the LED strips from you in the past and they are amazing at curing my screens. They cut my time almost in 1/3 of what it was. It takes at most a minute and this machine is closer to 3-5 exposure time. 

We did a bit of searching and was able to identify the model number as a 1000 watt halogen lamp in a T4 form factor. Unfortunately, we don't have the ability to produce anything in this shape, but we would certainly recommend looking into several of our UV light options.

Our first recommendation is our 20-watt UV flood lamp in 365 nm, which should provide light output in a similar manner as the fixture currently used for the T4 lamp. We've included the link below:

Another option would be our newly launched realUV LED flex panel, which works similarly to the LED strip lights you purchased, but in a multi-row array. Below is the product link:

Both product options are offered in 365 nm wavelengths, which effectively and efficiently target the wavelengths needed for photochemical processes such as screen printing.

Do your 365nm UV-A products offer true ultraviolet output?

Is it a true 365 nm? No blue light showing. Might order one to see if it will work for our manufacturing company. If so, will be ordering many. 

We can confirm that our 365nm ultraviolet products offer true ultraviolet output without utilizing purple-colored LEDs as other products often do. 

As can be noted within the product photometric report, the output for these products is beyond the 400nm visible spectrum, which results in an extremely minute quantity of visible light. 

If you would like to try out these products for direct comparison, please feel free to take advantage of our 30-day return policy. 

So long as the LED Strip Lights have not been cut or altered, such as having the adhesive backing removed, we would be able to accept them as a return. 

I will be using them to light up the bottoms of swimming pools. I had considered flood lights. What do you suggest? I have tried strips before and did not work. Not enough output.

We can confirm that the 365nm realUV™ LED Flood Light has a UV energy output of 8W, whereas our 365nm realUV™ LED Strip Lights have a UV output of 0.7 watts per foot. 

As the LED Strip Lights are not IP rated for protection against water, we do not encourage use in installations where they may become exposed to moisture or water, as this will cause electrical hazards and void the product warranty. 

Further, it might be helpful to know that third-party waterproof channels are typically made from polycarbonate materials that are known to fully block the transmission of ultraviolet light. 

As such, we would likely recommend the 365nm realUV™ LED Flood Light, as it is IP 65 rated for wet location use. Finally, please note that this IP rating does not mean that the product is suitable for submersion in water. 

Shortwave LED Strip Lights

Do you have shortwave UV strip lights rated for outdoor use?

While we do not have any ultraviolet LED strip lights that are compatible with outdoor installations, you might alternatively be interested in our IP65-rated realUV™ LED Flood Light. 

I am concerned with the floodlight. I think that kind of light is not good to have pointed where people can look into it. This is going to light up a low wall about 18” high made from Franklinite. My concern is it could damage people’s eyesight being uplit instead of Downlit.

Generally speaking, 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:

The ultraviolet emitters have a very high intensity when used at a very short distance, but less so at longer distances. Therefore, ensuring that people or animals do not come close to the UV source can help reduce the risk of any eye safety issues.

Ultraviolet energy is mostly invisible to the naked eye. It can be difficult for the vision system to recognize a high level of UV “brightness” and produce a natural response to squint or look away, in the way that natural white light would.

Do you have a black light for an industrial setting inspection table?

I am struggling to find retail or whole sellers who can help me with black/UV lights. I am looking for a black light for an industrial setting for an inspection table. Do you ship to Australia or can you recommend someone in Australia who could help? Or do you have a product that could help? 

You might be interested in our realUV™ LED Strip Lights and realUV™ LED Flood Lights, which are available in both 365nm and 395nm. 

UV LED Strip for Outdoor Lighting

I'm trying to find an LED strip like your realUV but I need them to be outdoor rated. Do you have a recommendation for that, or know of someone who may? 

Unfortunately, our LED Strip Lights are not IP rated for exposure to the elements such as outdoor installations, and I do apologize for any impact this might have on your purchase planning. 

As an alternative, you might be interested in our IP65-rated realUV™ LED Flood Light, which is available in the same 365nm and 395nm options as our realUV LED Strip Lights. 

365 nm vs 395 nm UV LED Strip for Halloween Decorations Blacklight

I would like to buy a blacklight for my Halloween decorations. I have read the article on your site and I am still having a hard time choosing which to get. I know the 395nm has more visible purple/blue light and I am wondering if getting the 365nm is worth it. I can get 4 of the 395nm for less than 2 of the 365nm. I have an open-concept kitchen/Living room and want the whole area lit up in UV. Would it be better to get 2 of the 365nm or 4 of the 395nm? I would like to use them outside too when not in use for the party. 

As each floodlight is able to cover a 10x10 ft area, you may find that utilizing several units of the 395nm option to be a more cost-effective solution. 

The being said, we can confirm that the 365nm option will offer the superior fluorescent effect between the two, as the output is further from the 400nm visible spectrum. 

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. 

What is the difference between 395nm and 365nm realUV LED Light?

I need a trustworthy ultraviolet light for an art project (exposing cyanotypes on paper) I was wondering if the realUV flood light would work for my needs. I noticed there are two options: one is 395nm and the other is 365. What is the difference?

We have attached an informative blog post below regarding the topic, which we hope proves to be useful for your purchase and installation planning. 

In short, as the output of the 365nm version is well beyond the 400nm visible spectrum of light, the fluorescent effect will be greater than the 395nm version. 

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

Is the UV-A light from your LED strips invisible to the naked eye?

I am looking at purchasing your UVA LED Strips. Based on my understanding of UVA light, it should be invisible to the human eye, but we see it coming from the bulb due to a coating that is put on the bulb. Is the light coming from your strips invisible to the naked eye, or do you have a coating that makes it glow purple? I only want the lights for my boat to make my fluorescent fishing line glow. I don't want a purple glow coming from my boat that may scare the fish.

As our 365nm realUV™ LED Strip Lights emit light beyond the visible light spectrum, we can confirm that only a very faint amount of illumination is emitted from the product during operation. 

We can also confirm that we do not coat these products with any type of glass or material that would increase the purple visible output. 

Do you guys make a waterproof UV light? I would like to use the light in my boat.

Unfortunately, our LED strip light products are not waterproof, and I do apologize for any impact this might have on your purchase planning. 

While some of our customers have been able to locate insulated waterproof channels to install these lights on their boats, it might be helpful to know that polycarbonate materials often used in channel products are known to block the ultraviolet output, which would likely negate any benefit for your installation.

That being said, you might also be interested in our realUV™ LED Flood Light, which is IP65 rated for wet location use if a compatible power outlet was available aboard your vessel. 

High-powered UV LED Flood Light for Outdoor Installation

I found your site and I need help finding a high-powered UV LED flood light. It needs to be a wet location. We have a large area outside we are trying to light up. We have interactive displays with UV paint, and we need to make that glow. 

Though our LED Strip Lights are not waterproof, you may be interested in our IP 65 rated realUV™ LED Flood Lights, which can be installed and used in wet locations. 

How big of an area will the realUV 365nm cover? We are mounting it outside on a pole between 10 and 12’ off the object we are trying to light. About a 25’x 35’ area with obstacle courses painted with UV paint. So maybe 4 to 6 fixtures? 

Generally speaking, the realUV™ LED Flood Light will illuminate an area that is roughly 10x10 feet. For installations where the strongest fluorescent effect is desired, we would recommend the 365nm version of the product. 

In case it proves to be helpful for your installation planning, we have attached a link to the product’s UV Irradiance Chart below.

UV Irradiance Pattern 

At the bottom of this document, you will see the measured microwatts per meter squared output that will land on a target nine feet from the light source. ​​

How far does your flood light illumination reach?

I would like to purchase a UV light with the longest distance capabilities. Ultimately, I need to illuminate 100 meters in length. Can you recommend a product or several products? How far does your flood light reach?

We have provided links to the UV irradiance patterns for both our realUV™ LED Flood Lights, as well as the realUV™ LED Strip Lights below, which we hope prove to be useful for your installation planning. 

These documents chart the microwatts per square centimeter ultraviolet output based on the distance between light and target. Generally speaking, LED floodlights can illuminate a target that is roughly 10x10 square feet.

365nm realUV™ LED for Photography Studio Black Lights

I'm disappointed that it seems the old F40 black light bulbs seem to be dead. No more cheap fun black light bulbs. I was going to build an array of four to six f40s for a black light body painting shoot. I know LED is different but as you guys are the 365 nm experts. Would you recommend the flood light style or strip style LEDs for this application? Do you think one LED flood will compare? Wattage seems kind a low compared to 240 watts of florescent.

Based on my review of the details provided, it appears that either the strip lights or flood light products could be a great match for your installation, depending on the preferred configuration. That said, the floodlights would likely be easier to install and adjust than the strip lights. 

​As such, our primary recommendation would be to compare the UV output of the previously used F40 light sources against that of our 365nm realUV™ LED Strip Lights and 365nm realUV™ LED Flood Light products.

Though the wattage may be significantly less, there is a chance that the measured ultraviolet output of our products is greater than the previously used items F40 lights. To help with the product comparison, we have attached links to the irradiance patterns of both products below for your reference.

Do you have an IP-rated 365 nm UV LED Strip Light?

I need an IP rated 365 nm UV rope for use in a pool. I would like to discuss this if you offer it.

As our LED strip light products are not IP rated for protection against water or the elements, we unfortunately may not have the ideal product available at this time. We apologize!

As an alternative, you may also be interested in the realUV™ LED Flood Light product, which is rated IP65 for wet location use. 

How many flood lights needed to properly cover a 4x4 area for plant growth?

How many flood lights would I need to properly cover a 4x4 area to help with plant growth?

Generally speaking, each realUV™ LED Flood Lights are able to illuminate an area that is roughly 10x10 feet. In order to calculate the appropriate ultraviolet output for your plants, you may find value in the below irradiance pattern resource document. 

Depending on the μW/cm2 light requirements of the plants being grown, one floodlight might be sufficient for your 4x4 area. That said, you may find that adjusting the distance between light and the target, or potentially utilizing multiple floodlights in order to reach a preferred μW/cm2 output, to be beneficial for the growth of the plants.

365nm realUV™ LED Flood Light Spectrum Test Report

Do you have an LED strip light that emits no wavelength visible to humans?

Is it possible to get an LED strip light that emits no wavelength visible to humans (strictly near UV, say 375 nm)? We have your 365 nm and it appears to emit some light above 400 nm that is visible to humans.

At the moment, we currently do not have any other specific ultraviolet nanometer wavelength options beyond 395nm and 365nm. We apologize!

That said, there may be filters available from third-party providers such as Lee Filters that could potentially block the transmission of the small amount of visible wavelengths. 

Is there an outdoor-rated UV LED strip light?

Though our LED strip lights are not IP-rated against contact with the elements, such as moisture or condensation, we heard from those installing the lights on boats that waterproof channels appear to be available from some third-party manufacturers that insulate them against rain. 

​Unfortunately, we are not aware of the exact manufacturers or products used. That said, please keep in mind that any contact with liquid may cause an electrical hazard and will void the product warranty.

Alternatively, you may also be interested in our realUV™ LED Flood Light, which is IP-65 rated, and is therefore suitable for outdoor installations where it may come into contact with rain or other natural elements.

Does the realUV LED floodlight have a protective cover that prevents touching the LED?

I have a couple of questions about the realUV LED floodlights, 365nm: Does the light have a protective cover that prevents touching the LED? Your spec sheet does not address this. What are the microwatt/cm^2 at 16in the output of these lights? Do you offer a handle for use vs the mounting bracket?

We can confirm that the LED floodlight utilizes a pre-installed protective cover over the lamp. The covering assists in the IP rating against contact with moisture or condensation.

We have also attached a link below for the UV irradiance pattern for the product below, which displays the irradiance pattern for several present distances from the subject. I do hope that this is helpful in your irradiance calculations!

realUV 365nm 20W LED Flood Light Irradiance Pattern: https://www.waveformlighting.com/photometrics/BP_7022.pdf

Additionally, we currently do not offer handles over the mounting brackets. We apologize!

Are your RGB LED strip lights waterproof?

I have two tall (20' or so tall ) walls that I'd like to light up. Are your led color-changing lights waterproof? Also I can use any 120 to 12 v power correct? Do you have any exterior sign lighting ideas/recommendations?

Unfortunately, our RGB LED strip light products are not weatherproof or IP-rated. As such, they may not be the right product for your installation, and we do apologize for any impact this might have on your planning or installation purposes.

Currently, the only IP-rated product in our catalog is the realUV™ LED Flood Light product, though this item would not be able to output the preferred RGB spectrum.

Can the 365nm UV LED Strips be used in a growing tent?

Can the 365nm UV strips be used in a growing tent or do your T8 LED bulbs have UV in the full spectrum? 

We can confirm that our UV strips are usable in horticulture installations, though please be advised that the LED strip lights are not IP rated.

As such, any installation utilizing them would necessitate a waterproof channel to protect the product against moisture or electricity, as any contact could cause an electrical hazard and void the warranty. That being said, you may alternatively be interested in the realUV™ LED Flood Light, as it is IP65 rated and available with 365nm output.

Unfortunately, our T8 LED tube light products currently do not offer UV output. We apologize!

How could I operate your UV Floodlight as a camera flash?

Any idea how I could operate your UV Floodlight as a camera flash during acquisition?

As the product is only able to be turned on and off by being connected or disconnected to wall power, the primary solution that we have would be connecting the product to a power supply that could be controlled remotely. However, there might be a delay in illumination that would need to be calculated, so that the control can allow for the preferred illumination at the right time.

Alternatively, the product could remain illuminated during camera capture and unplugged when no longer needed. ​

Unfortunately, we do not currently have any additional resources or instructions for how the product could be configured for camera flash purposes. We apologize!

UV LED Flood Inspection Light for Rewind Section on Slitters

I am looking for a recommendation on which flood light to order for material inspection on the rewind section of one of our slitters. The light will be used for very basic visual inspection. The material being rewound have a coating which is visible under UV light. The operator will use the light at low speed to check for uniform coating. The light or lights will illuminate the rewind section of the machine and will be pointed away from the operator towards the material. 

Our experience in this specific industrial process is a bit limited, so while we do not have any immediate recommendations.

If you have any technical data on the coating, that would help us determine the UV requirements.

Generally, however, the 365 nm would be the best wavelength for visual fluorescence UV applications. As such, this may be a good starting point for running tests if you would like to take an empirical approach.

Please see below for a direct link to the 365 nm UV LED flood light:

realUV LED Strip vs Floodlight for Small Display Cabinet

Looking to light a small display cabinet with 365 nm. Would you recommend the LED strips as a better way. How is the floodlight mostly used?

For installations such as displays, many of our customers prefer to utilize the 365nm realUV™ LED Strip Lights product due to the low profile within the displays and flexible installation options.

Alternatively, some customers prefer to utilize the floodlight for directed spotlight illumination. Often, the floodlight is installed on ceilings for artwork ultraviolet illumination using the pre-installed bracket. Other customers prefer to floodlight for outdoor installations, as the product is IP rated for protection against the elements.

UV LED Light for Tennis Court At Twilight

I want to be able to play tennis starting at sunset, for an hour. I think that maybe using 2 UV flood lights, one on either end of the court, or possibly 2 UV flood lights, at the net, back to back, each facing towards one side of the court, would be good. What would you recommend? Have you seen this done before? I want the setup to be easily portable - I don't have anywhere to put big lighting rigs/standup poles. What are your recommendations? 

Unfortunately, the realUV™ LED Flood Light might not be the best product for illuminating a tennis court.

This is because these ultraviolet products are not designed with an output that is visible to the naked eye. I do apologize for any impact this might have on your installation plans.

Further, we, unfortunately, do not currently have any other floodlight products at this time that I could recommend.

If we pretend that this line of thinking could maybe work, and all I needed to see was the tennis ball, the dimensions I would need to be able to see the tennis ball are an area of 80 ft x 30 ft --> 2400 sq. ft. This is slightly bigger than the dimensions of a court. How would I illuminate an area of this size using your blacklights? 

Generally speaking, the realUV™ LED Flood Light can illuminate an area that is roughly 10x10 feet with UV-A output. Further, the irradiation pattern is such that distances and objects at 6 feet from the light source will receive about 47% of the maximum UV-A output.

Evenly distributed, 23 units of the floodlight would optimally wash the area in ultraviolet light, though you could also mount 10-14 units on the courtside boundary facing inward towards the court, though you would likely encounter more limitations of the irradiance pattern on the inner court. In case they prove to be helpful, the product page has several irradiance patterns for reference. 

Can we block all visible light in the 365nm UV LED Light?

Can we block all visible light in the UV LED 365? Also, do you sell a UV pass filter as a thin film?

Though I can confirm that the 365nm products will emit a very slight amount of UV, some customers have utilized UV bandpass filters to limit the visible output of these products. Though we currently do not sell any similar UV bandpass items at this time, some options should be available from other third-party manufacturers.

UV LED to Lighten Color-Anodized Aluminum Pieces

I'm planning to make an enclosed UV light exposure box for white "yellowed" sneaker soles and to lighten color-anodized aluminum pieces. Are your UV LED lights capable of handling these tasks? If so, which UV wavelength would be best to use: 365nm or 395nm? 

Unfortunately we do not have any data or testing on the applications you mention. Based on a basic understanding of polymer and plastic science, exposure to UV radiation will generally cause the material to degrade and yellow further, rather than return to the original white color.

​If you have any further technical information on the materials you are interested in working with, I would be more than happy to take a look and offer my suggestions.

365 nm is generally considered to be a "truer" ultraviolet wavelength, so this would be the best option if you are after a UV lighting solution that best represents your needs for UV-A.

I had forgot to mention that, for whitening sneaker soles, a product is used that when the sole is coated and then exposed to UV light for a long period of time, the old yellow sole is restored to white. I have used this product called "Sole Bright" with good results.

I got great results using sunlight, but the exposure sessions are long, especially when there are cloudy days and I would have to wait for the sun to return.

Others have used enclosed UV light boxes to speed up exposure time without depending on sunny weather. Only issue is that they dont provide specific info on what UV light source they use. 

Unfortunately, I was not able to glean any further insights as far as wavelength sensitivities are concerned. Sunlight includes a very wide spectrum of ultraviolet wavelengths, so it's hard to know which of those wavelengths are the ones doing the "heavy lifting" in terms of the restoration process as all I see on the product page are instructions for sun exposure.

​As mentioned prior, 365 nm is a "truer" UV wavelength so if I had to guess, that would be the most effective wavelength choice between that and 395 nm, but without seeing technical documentation regarding wavelengths from the Sole Bright manufacturer, I don't know that I'll be able to provide any additional assurances.

I would perhaps recommend reaching out to Angelus to see if the 365 nm wavelength is a match for their product and go from there.

Do your UV lights have energy to reach the bottom of the swimming pools to charge glow products?

We are a manufacturer that produces glow artistic products. We service commercial builders and pool builders. I plan to possibly use your 395 or 365nm floods or strip LEDs to charge them up throughout the night hours. They will be on a timer that will turn them on and off at different intervals. My question is, do you think your UV lights have enough energy to reach down about 6 feet to the bottom of swimming pools to charge our glow products? Please see attach drawing that has attached for you to better understand the process. 

Based on the diagram provided, we would likely recommend our IP65-rated 365nm realUV™ LED Flood Light product, as our realUV™ LED Strip Lights are unfortunately not suitable for installations where they might come in contact with water or condensation.

Though the realUV Flood Light is designed to output ultraviolet output for an area that is roughly 10x10 feet, we have not performed internal tests regarding how water depth can affect or scatter the UV output.

As such, it is difficult to say whether or not the ultraviolet wavelengths could successfully reach the glow oxides. In this instance, we might recommend trying them out and taking advantage of our 30-day return policy. If the products don’t work out, simply reach out and we will gladly provide you with a prepaid return label.

Recommended Installation for UV Reactive Tapestry

I have a room that is roughly 130 square feet. There are 3 walls and where the 4th wall normally would be is just a transfer into my kitchen. I have a UV reactive tapestry on all sides of the room besides obviously the entrance to the kitchen where there is no wall. What setup would you recommend to effectively light all of my tapestries with good UV light? Also, would you suggest 356nm over 396nm in this situation? 

For an installation that would benefit from the most UV effect, we would recommend the 365nm version of our ultraviolet products.

Though the realUV™ LED Flood Light product is easy to install, it can take up more room than the alternative, which may not be ideal for all installations. Generally speaking, one 365nm floodlight should illuminate an area that is roughly 10x10 ft with 8.0W of UV output.

Alternatively, the realUV™ LED Strip Lights can be installed in many different ways, though it will require a dedicated power supply. Based on my estimates, I believe that one full 16.4 ft reel should be more than enough for the dimensions, as it outputs .75W of UV output per foot.

I have attached a few links below for our realUV LED Strip Light LayoutMaps, which provide detailed installation instructions, as well as links to the recommended accessories.

Waveform Lighting LayoutMaps™: https://www.waveformlighting.com/layoutmaps/

LayoutMaps™ - LED Strip Light Layout 7021_4A

LayoutMaps™ - LED Strip Light Layout 7021_4B

LayoutMaps™ - LED Strip Light Layout 7021_4D

If I used the flood light would I have to place the light in the center of the room on the ceiling? or could I put it on a wall facing the room to illuminate my art in a 10x10 room

We're happy to confirm that the floodlight should be easily installable in either method, thanks in part to the adjustable bracket.

It might also be helpful to know that the irradiance pattern will have the most concentrated output directly in front of the light. As such, you may decide to position the light such that the most important artwork is best illuminated.

Do you have LED lights for Pool Lighting

Do you have lights I can put around my pool on the outside under the ledge? They might get splashed.

With the exception of the realUV™ LED Flood Light product, the other items in our catalog are unfortunately not rated for contact with water or moisture. Generally speaking, any contact that these products have with moisture could cause a safety hazard and void the product warranties.

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:

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.
