you could get a surefire a2 aviator and get one of the members here to make you a UV led ring. i would say that would be your best bet, seeing as you need dual light. that way could also chose the corect wavelengh for what you need.
Pila GL series or Wolf Eyes (Raider, Cobra) with Xenon high intensity output main lamp and IR LED tailcap. You won't be disappointed. Great ergonomics. No fussing about pressing buttons getting to proper mode. You have high intensity overhand in your fist a critical moment and guaranteed low intensity or UV underhand with a twist of the tailcap. I can't find a design improvement to this day.
