>>Keychain Black Light
UV Fluorescence - small, and one of the brightest ultraviolet lights available. You can detect counterfeits, check UV fluorescent hand stamps & much more. Our UV / Ultraviolet light ("Blacklight") LED flashlight is perfect for activating fluorescent ink, strips & fibers used in bank notes, credit cards, casino chips, passports, checks and more. This is just an amazing light, useful in so many situations. This is the one to have in your pocket, car glove box and desk drawer, and it certainly is the right size. You just ever know when you will need another. This little beauty will be a constant companion on your keychain. The body of this mini-UV flashlight is metal, made for years of use.
The UV LED beam has a fairly narrow focus and unlike a traditional blacklight, most of the light produced by the UV pocket light is just outside the visible spectrum (395 nm). In full darkness it will cause objects to fluoresce at distances of 6 feet or more. In bright daylight the effectiveness is greatly reduced, but is still usable at about 6-12 inches. So good, this uses a lithium battery. This metal mini light is a little over 2 inches long.
The uses of this black light are numerous.
