21 LED 395nm UV Flashlight

Descriptions:
A UV flashlight emits ultraviolet radiation - a type of light energy - that is not visible to the human eye. When ultraviolet light hits certain objects, they can fluoresce - a phenomenon similar to a bright glow. Many objects and substances such as paints, dyes, minerals, animals and body fluids exhibit fluorescence, which means that the presence of these things can be detected only when a UV light source shines on them.
The beam light which it gave out is bright and wide and this bright beam can be seen miles away in the dark, that you can use it to guide your ways. It is a really wonderful tool for household using! This flashlight is featuring a high-quality material that is sturdy and durable enough for long time daily use.
A UV flashlight takes the same shape and format as a standard white light flashlight, but instead of emitting white light, emits ultraviolet light. Virtually all UV flashlights use LED technology.
