Re: Purpose for Different Color (including UV and Infrared) LED\'s
UV lights make excellent fake currency detectors. When shone on REAL currency, usually some sort of hidden marking will 'magically' appear. While everything else is dull purple under UV light, these markings glow somewhat, sometimes very prominently.
Infrared is useful for those using NVG(Night Vision Goggles) as these will enhance their use. I've also tried using an infrared Arc-AAA with my video cameras with teeny-weeny success. In total darkness, one of these will illuminate(to the camera only, not my naked eye) my face up to about a foot away. Very limited use unless you own NVGs or are doing some sort of experiment.
Go for the UVs first - they're fun and practical
