DARKDAWN UV Flashlight 395nm Black Light Mini USB Rechargeable Ultraviolet LED Blacklight Woods Lamp Powerful Fluorescent Portable Detector for Pet Urine Stains, Scorpions, Resin Curing

It functions as a black light. I tested this on some gemstone jewelry and it lit them up.

FABULOUS!! I was looking for a portable blacklight to use when out and about looking for uranium glass in the wild. This does not disappoint!! Very bright! Works even in daylight situations, which as anyone perusing yard sales, thrift shops, flea markets & even the odd antique store are more often than not saturated with light. This is portable, feels solid in my hand and what a great price! Love that it is easily chargable. So pleased with this flashlight, and I'm sure if I wanted to use it for scorpion hunting it would work for that as well. Buy one you'll be happy too!!!

Works like I needed it to. Great uranium light.

Cures my UV epoxy nice and quick, and I can adjust the beam size if I need a larger area covered. Mind you, the larger the beam, the less intensity it has, thus the curing time will be proportionally longer. WITH THAT SAID, the ONLY negative I see here, is that you will get to a focal distance where you'll see the LED array projected, meaning the light isn't being defused enough and is concentrated on that spot and outside of it, you're not getting much curing done. For me, it seemed to be around half-extension point. But outside of that small window, this is great. It's so great, I bought my friend one, who was using a dinky button cell push UV light for his field work in Exotics Veterinary. He uses UV resin/glues for shell and beak repairs all the time. This cures faster, doesn't get hot, and holds a charge for a lot longer. I also love the fact that you can open this guy up, pop out the 18650 cell, and put a new one in, if anything should happen to the cell. Meaning reduction in E-WASTE since the LED should long outlast the battery. It does charge a bit slow, but is to be expected from these devices, they all seem to be plagued with terrible charging circuitry. In conclusion, 100% would recommend, the focusing gimmick works great, easy to manipulate, hard metal shell, perfectly sized to be not too big or too small, replaceable battery, so if you do need this for prolonged field use, you can just chuck a few extra 18650 cells in your bag. Loved it so much, bought one for a friend who has gotten a lot of use out of it, already. Veterinarian and hobbyist approved.

Great for what it is used for, like thrifting and looking for uranium glass, and other glass that glows. Also works for finding the spots on carpet that your pup may have had an accident. It’s a pretty strong light compared to the little pen lights. And I like being able to recharge it.

This is the perfect black light flashlight. It very night and the area it covers is huge.

Nice application of the rechargeable flashlight design applied to UV instead. This unit is powerful enough, I swear it feels like it'll sunburn me if I shine it at my face for a good 5 minutes, a standard measure of power I use.

I use it to check money for work. It works great. It zooms in and out. Charging port is great, usb c port with cable included.
