Best quality ever? No but certainly serviceable for occasional use and the price is right. Can’t ask for more! ### ⭐⭐⭐⭐⭐ Works me and my uranium glass wars. *by on Reviewed in the United States February 8, 2026* Works great for me to find uranium glass at the thrift stores. I have been hunting for about a month now and have attached a photo of the current collection.This thing fits in the pen pocket of my chore coat (snug fit, but fits), easy to hold in had and quickly click on and off check the glass without looking too weird. It takes 2 triple A batteries which are cheap and easy to find.I haven’t tested the difference between this light wavelength (395) and the other (365) but I will get some of those to try out as well.For the price, worth it. Get at least two so you can lose or give one away to another hunter you meet along the way….as long as you understand they will be your nemesis from that point forward. On second thought, keep the other and use both when they are looking so they know they have been defeated by a superior being with superior technology. No kindness in the thrifting uranium glass wars. No mercy. Find them all. Hoard them. Don’t let THEM have any! Don’t read this. Don’t buy a light and stay away from my thrift stores!!!! ### ⭐⭐⭐⭐⭐ COSOOS 2 UV Black Light Flashlight, 2 Pack 395nm Mini Pen Light with Clip, Waterproof Ultraviolet *by on Reviewed in the United States April 20, 2025* I recently got the COSOOS 2 UV Black Light Flashlight 2-pack, and I’m really impressed with their performance and convenience.
