Best UV flashlight
This is a metal (aluminum) UV flashlight is small, takes 3 x AAA batteries, that really throws out a lot of UV light with its 21 UV LEDS. It's a pretty rugged construction. As for uses; there's so many. For me, it's been great for testing what things look like with UV, such as UV reactive paint, fabrics, plastics, etc. Useful when you go shopping for materials for your haunt or looking around the house.
