Whenever you're looking for a torch, UV-ED, ... you need to go to the 365nm. When visible light is filtered you hardly can make out the visible light.
The fluorescent effect is much stronger than with 390 - 400nm LEDs. Some minerals and fluorescent colors need to have the shorter wafelength to show this effect at all.
Thre really nice feature is the step up converter in this particular flashlight. It runs from one singe AA battery.
