Keenstone Rechargeable Flashlight Morpilot 2 IN 1 UV & LED Torch (White Light and UV Light) with Pocket Clip, 500 Lumens and 4 Light Modes Flashlight Zoom OUT/IN Waterproof IPX 4. This black light is perfectly powerful for a flashlight. I honestly just bought it to have fun.This black light is much more powerful than I thought it was going to be. Not only is it small, it feels well made. Nothing I can complain about, it works well. Would recommend it.
