Black light?

[Caferacer]

If any of you are handy with a soldering iron it is easy to buy UV leds from places like radio shack. Then you can just get a cheap LED flashlight and take the old LEDs out and put the new ones in.

Cmon I can't be the only engineer here thinking that Hell you could even get both kinds of LEDS and have a long and shortwave emiting flashlight.

Only problem is I think those LEDs draw less, so you might need to solder in a resistor as well.
