 Stylus® UV LED Flashlight - Black By: Streamlight Average Rating: 5.0 Total Reviews: 2 More Information UV pen light  On: 2008-02-08I have several different styles of the Stylus pen light products and you cannot buy a better or more rugged flashlight for gem and mineral work. Want to know if that $20 is counterfeit? On: 2007-08-14This is a great little tool, compact and powerful. Its useful anywhere you need a little bit of UV light. I can see stores keeping one behind a register to quickly check currency (US paper currency has markings that flouresce under UV light). Most state IDs and credit cards also have UV markings that are hard to counterfeit. Mechanics can use this to check for leaks in your AC (when phosporescent die si introduced to the system). Forensic document examiners may use this to check for differences in ink. Its inexpensive, highly portable, and works well. If you need a limited UV light, this is the tool for you. |
