What makes this violet/near-UV light
different from the rest isn't its cool looks, but it's
beam. This light produces a very wide angle beam, which
some people prefer over the narrow beam for tasks like
checking UV security features in documents and
illuminating vaseline (uranium) glass.
The "Counter-Detect" is a
keychain sized violet LED flashlight. The decidedly *cool*
looking unit is equipped with a wide-angle near-UV LED
emitting at just under 400nm, and is powered by 4 coin
cells. This Portable UV Money Detector, detects
counterfeit currency. Features a UV detection Bulb, in a
compact, lightweight housing doubling as a keychain. It
includes one extra set of 4 batteries. Packaged on an
attractive retail color card!!
