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

I don’t normally write reviews, but this time I had to!! If anyone else has UV reactive glass like selenium, uranium and cadmium, THIS IS THE LIGHT!!! I’ve been struggling to find a light that makes my selenium and cadmium POP but this light finally did it! Even my manganese wine glasses are glowing!!

This thing is the real deal, not just a purple light. Lit up my tapestry like crazy! Well worth spending a few extra bucks to get the 365nm 50W This size light is good for one average size wall.

This is a decently powerful light for the price and meets all my requirements, but users should be made aware that this is absolutely hazardous to eyesight! Cheap filterless UV LED's like this will blast a wide range of wavelengths and only emit the most at 365nm in this case. 365nm alone is known to cause skin cancer from prolonged exposure. Doing something like holding your hand right in front of the light for a minute or two can cause instant sunburn. Your eyes are much more sensitive, and that includes reflections! You don't have to look directly into the light to receive permanent retina degredation, an illuminated room by this can hurt your eyesight (especially if there are lots of white surfaces). It's a great lamp, but you must look into the safety precautions necessary for something like this. I use it for curing UV reactive resins and cyanoacrylate. UV filtering safety glasses are absolutely mandatory if you are using this repeatedly. Do NOT use this for curing gel nail polish on fingernails! You will seriously hurt yourself!

Works well, ran for 8hours straight no issues

It works, it works a little too good lol it hurts your eyes and blind you. If it's facing towards you i bought it for inside to really light up a room like we used to back in the day.And that way my glow in the dark posters and stuff.But this is not for that, because it hurts your eyes, and you just can't do it. If it's for outside up against a house or something, it would be perfect. I mean, you can use it inside, but you'd have to face it up against a wall or something.Not anywhere where you can look at it.

I ordered the Everbeam 365nm 50W UV LED Black Light for Cyanotype Projects. Used in conjunction with a handmade ‘light box’. Takes about 6 minutes for dry cyanotypes, 9 plus minutes for wet cyanotypes. Works great. Provides a consistent light source.

I've been using this UV lamp for processing my cyanotype prints. I love it! I use a large cardboard box, cut a square hole in the top just a bit smaller than the lamp and line the box with foil. This gives me consistent results with my cyanotype developing. I highly recommend.

I've only used this a handful of times and all of a sudden, I turned it on and the light was SUPER dim, hardly putting any light out. I use it with a homemade light box for cyanotypes and I'm so sad I have to research to find another light. I do know that I set it down on the counter, face down for literally a couple minutes before I realized the light was still on. I guess thats all it took to fry the thing. Really bummed. Wish there were more of a warning. Only reason I can think of why it has failed.

It meets the expectations for a 45 m2 room. Despite the obvious fact it should be used at night, keep in mind that the room itself better have a darkish interior design to get the most out of it.

Arrivo nei tempi previsti. Oggetto integro e funzionante.

je viens enfin de pouvoir la tester - suffisante pour le cyanotype - 8/10 minutes de temps de pause pour un format 24x32 - j'ai fait des tests en laissant la lampe allumée 35 minutes - elle chauffe mais rien de dramatique - elle n'a pas du tout marqué la boite carton sur laquelle je la pose -

I had to chose between two wave length, 365nm or 395nm. Both gives good result with some difference. The 395 appear stronger because it flood the area with some amount of visible light. It’s a deep blue color. The 395nm will not illuminate stuff that are manufactured to “glow in the dark”. The 365nm will project some amount of visible light but much less. On the other hand, the spider web in the left corner will “glow” and it is a “glow in the dark object” that would not reflect any light under 395nm. For me, the 395 was to strong in the visible light spectrum. Many mentioned it overheat and become really hot, for me it's not an issue, after 8 hours it was warm but not hot. It's a good product, solid, well designed and worth buying at 50w. I used Crayola Neon Chalk for drawings.

Cumple su cometido y no se calienta mucho, lo esperable. Los he tenido encendidos varios dias encendidos permanentemente sin problema
