ALONEFIRESV18 12W 365nm UV Flashlight Powerful USB C Rechargeable Woods Lamp Black Light for Pet Urine Detection, Resin Curing, Minerals, Fishing,Scorpion, Bed Bug with UV Protective Glasses,Battery

Works great. Shows fluorescence nicely. Doesn’t get too warm, especially if you use it intermittently. It’s sturdy and handles dirt well. Overall solid for the price!

Light is super bright! It illuminates all my uranium, cadmium, and manganese glass very well. It’s a little bigger than I was expecting but I didn’t check the size so that’s on me. Seems sturdy and well made, the battery compartment in the back screws in and out to hold the battery (I should mention, battery is included! Woo hoo!)

I already had a UV pen light, but wanted something bigger. Then, I bought this. This thing will light up an entire back yard full of whatever could possibly glow when UV light hits it. I have a large back yard. Do not under any circumstance aim this thing at anyone's eyes! There is a warning label on the head of this flashlight for that reason. Don't get it too close to skin either. It will burn. The head of this light will even make for a hand warmer during the cold of winter. Another bonus is that you can remove the 21700 battery, and replace it if it goes bad. Or, put it on an external charger, prolonging the battery life.

It works great! and decent quality

Received with broken UV glasses, kind of a bummer. The light is a nice machined metal construction unit consisting of battery tube, base and head. Feels good in the hand and has a lanyard for safety.Doesn't come with any instructions and amazingly I haven't seen any posted so I'll note that after a full charge 1 press of the button is full power, press again after 3 seconds and get low power, again and it's off. Or, pressing it twice in quick succession turns it to strobe.It seems fairly powerful, low power is what I'll use for indoors. Only had it a day so can't speak of it's longevity..

I bought this as a replacement to an old fluorescent blacklight for detecting cat urine stains on carpet. It is vastly more powerful; while the fluorescent needed to be an inch or so away from the stain, this will light things up at a distance of a foot or more even during the daytime (afternoon shuttered light in the house during full sun, low enough that you'd probably want a reading lamp to read but which would be fine for reading labels or just being at home). The problem is (which has nothing to do with the product), it lights up ALL organic type compounds so by itself you can't differentiate between old/treated and new stains unless the cleanser had no organics that would also fluoresce under UV light.I wanted a bright light (preferably from a reputable company but not overly expensive) that would easily pick up cat urine stains, and this was perfect. If I ever lose it, I will buy another. I haven't used it enough to comment on battery life, though.The UV glasses are a nice touch.

This is amazing very bright works better than the ones I have bought in the past. Nice quality. And good price.

First off, I'll start with a SAFETY Warning: make sure everyone within range or in the same room of this UV light is wearing UV guard glasses, and I mean everyone! This light can ruin a person's eyes if proper precaution is not taken. And DO NOT look directly into the lens to see if its working.Now, I've had this thing for a while now and it works awesomely and will light up any bacteria you missed in your household cleaning regiment. It also works great for identifying florescent compounds in rocks and makes spider and scorpion eyes glow in the dark. They make a more powerful version of this light but I feel this one is plenty powerful enough. I would recommend purchasing better quality UV Glasses. This is a great buy.
