A UV flashlight might look identical to a traditional flashlight. But UV flashlights are entirely different — they won’t light your way in darkness, and they don’t provide light you can see. Instead, UV flashlights emit ultraviolet energy, which isn’t visible to the human eye. However, that distinctive light can help certain items stand out or become fluorescent. A UV flashlight can illuminate objects and substances, like paints, dyes, fluids, or even some animals and reptiles, that you can see only when UV light shines on them. UV flashlights rely on LED technology to light up fluorescence and fluorescent items, giving you visibility when nothing is visible to your naked eyes. If you’re in need of a UV flashlight, there are plenty to choose from. And you can make the search simpler with the following top options.
