Review on UV Flashlight Ultraviolet LED Light Blacklight Portable 395Nm Detector For Pet Stains, Anti-Counterfeiting, And Resin Curing - Pack Of 2 by Anthony Cayton

These UV flashlights are the best! Especially if you pair them with 14500 lithium ion rechargeable batteries! They really give it an extra kick of brightness, and allow the light to last for ages on a single battery!It's also incredibly easy to take these apart for cleaning the lens and LED module if pocket lint happens to get in.There are gaskets that appear that they would offer some water resistance, but I haven't taken the risk with plunging mine into the water so I cannot vouch for it.The flashlight itself can get a bit warm if you leave it on for extended times, but I never felt that it got to too high of a temperature.A somewhat big problem I do have with them is that the metal edges on mine (especially those at the very front of the light) were pretty sharp out of the box. One of these lights have made plenty a hole in my pockets as I've carried it over the years. At this point, most of the sharpness has dulled from the many pockets they've worn through. I do suggest if yours have sharp edges and you plan to carry it in your pocket, that you sand down or otherwise dull them to save you plenty of mending or replacing pants!I highly suggest these lights if you have a use for a small (but bright) UV flashlight!
