Everbeam 365Nm 50W UV LED Black Light - High Performance LED Bulbs, IP66 Waterproof - Ultraviolet Flood Lighting For Aquarium, Indoor Or Outdoor Parties, Stage - Party Supplies, Halloween Decorations Review

After much research about the length of ultraviolet wavelengths, I found Nicole Small's videos. Cyanotype and Ultraviolet light. I bought this one. I tested the light and it make great cyanotypes. Look for 365 nm instead of 395 - 410 nm. 410 is too invisible. As seen in Nicole's video, I placed the cyanotype 9 inches away from the light source and after 7 minutes, I got great results. 10 minutes may have been better. and may need more if using negatives.

I realized the UV flashlights I ordered wouldn't arrive in time for the experiment. I flash ordered the floodlight and it arrived in 3 days. (Thank you.) The quality far exceeded my expectations. It included a 6-ft cord, 3-prong plug and inline switch (not mentioned in the description). The lumen output was phenomenal. I have no instruments to measure it but we performed the experiment in a darkened room rather that the black-out space reserved. Buying this light was one of the best experiences

Works well and flawlessly but just remember it's just 10 watts so it's not that bright outside or inside. just for some really close illumination.Gave it 5 stars because it works. Caveat is the use case as don't expect to see much if it's not totally dark.

This light was great, when it worked. It would cure a thick clear coat on fishing lures in under 5 minutes. Now, three leds are inoperable, the light output is greatly diminished and it does not effectively cure the resin. The light is less than three months old and not used often. Everbright has a two year product warranty. I will update my review if they respond in a reasonable amount of time and honor their warranty.

Perfect spectrum to show off my Uranium glass. Decent output of light. Good for the price but I left it on for 3 minutes and the back was hot enough to burn my fingers. I'll not be using often, afraid of leaving it on for extended periods of time.

Very bright flourescent effect with just a bit of deep blue fill. Got hot after 15 minutes but I could still place my hand on the heat sink.was uncomfortable though. Significantly brighter flourescent effect to visible light ratio compared to a 30 watt led blacklight bar that is 385-400nm (claimed). Probably overkill for for my 15x7 porch (perfect).

I bought this after seeing other resin printer guys were using it to cure their prints. Definitely gets the job done quick. I've seen some people post that the lamp does it get very hot as soon as you turn it on and I can confirm that it does. I don't think something like this is good keeping on for extended periods of time. For resin prints though, I'd give it 4/5. 3/5 for anything else

We made an Oogie Boogie Lair for Halloween and these lights were amazing. I bought Both the 100 watt and 50 watt just in case I needed and I'm glad I did. We have a really bright street lamp in front of our garage and I these lights worked perfectly.The I was hesitant on the price of the 100 watt, but I'm glad I pulled the trigger. I searched all over for 365nm 100 watt UV lamps, but nothing came close to these. 365nm will really make neons/fluorescents glow (way better than 395nm) and the…

I needed a bright black light for a Halloween ghost effect and everything else was too dim and too much in the visible spectrum. This provides a great black light effect, although it is certainly not invisible in the visible light spectrum. I was concerned with the heat from the back like some of the other reviewers but it's not bad. According to a laser thermometer, the 100W went from 60 F to 170 in fifteen minutes and 190 in an hour, so not nearly hot enough to cause a fire. Paper catches…

Great black light/UV effect, but this thing gets INSANELY HOT! I feel like the heatsink doesn't get the job done. After about 10min it is too hot to touch, I don't see how people could be using this thing for an extended period of time without additional cooling. After noticing the heat I started using a fan blowing directly on the heatsink to cool it and it still gets pretty hot.

These are small and inexpensive which is what I was look for for vacation bible school.Using them for recovery of Paul’s sight after blinding should get the kid’s attention, they all get a set of glow in the dark sunglasses 😎

Very unhappy with lights, did not create atmosphere as advertised. Didn’t react to fluorescent paint very well. The distance of coverage was not as advertised. I had a $6 black light pen from Harbor Freight that outperformed the spot light for reacting much brighter and not with any background purple light.

It seems to work but it gets super hot! I've just had it going about 5 minutes and it's already nearly too hot to touch. I'm wary of having it on unsupervised in case something ignites! I'm using it to cure uv resin but it's inconvenient to have to sit nearby and make sure nothing happens.

These lights worked great for a glow party, but I'm not sure the more expensive 365nm was worth it.I ordered 2 of both wattage sizes, along with a different cheaper brand that was not 365nm.These lights were cheaply built.One light had the (metal) corner broken off in its packaging during shipping, but still worked. They are made of that cheap pot metal that snaps into pieces.Another light had a bad row of leds that never worked, but the rest of the LED's worked fine and it wasn't immediately…

Very good product. Would recommend to anyone. Make sure you read description for dimensions. Smaller than expected. Thanks for attention!

The light appears solidly constructed with a strong cord. The cord has an on off switch. The light is really bright and nicely highlights fluorescent paint on objects

The light was great until a week after the return window. I noticed it was running hotter from the get-go than the 80w unbranded version that I purchased. It has a few less LED's than the 80w but the housing is much smaller which doesn't promote heat dissipation. Two diodes failed a week after the return period then three more a week later. The diodes have an inconsistent wavelength as shown in the picture, I am guessing they were bulbs left in the trash bin because they didn't pass factory…

It is for sure A bright uv light everything flows crazy bright, but the problem is it also is very purple. I would buy again but would Research more into other options at similar cost. (which is a fantastic price for this anyway).

Was nearly as bright as I was hoping but more so I don't believe this is 365nm. If it is, it's also got a whole lot of visible light that comes through and it bleeds out any of the uv spectrum. Granted it works but this feel a whole hell of a lot more like 395nm

The lamp emits a surprising amount of light from such a small unit. It is very solidly built. Great design! The product may not be as bright as claimed.
