This special-purpose Photon light produces a powerful beam of ultraviolet light, which will activate fluorescent minerals (long wave), fluorescent ink, strips, & fibers that are used as anti-counterfeiting measures in bank notes, credit cards, casino chips, passports, checks, securities, cryptographic papers, etc. These key-chain sized UV lights are also great for checking fluorescent hand stamps at clubs, or curing UV-sensitive glue. The UV Photon features an extended housing to protect your eyes from direct exposure to the UV light.
The beam has a fairly narrow focus and unlike a traditional blacklight, most of the light produced by the UV Photon is just outside the visible spectrum (370 nm). In full darkness it will cause objects to fluoresce at distances of 20 feet or more. In bright daylight the effectiveness is greatly reduced, but is still usable at about 6-12 inches.
CAUTION: Intense UV light can cause eye damage if viewed directly. Keep away from children.
