Walther UV5

This is the first flashlight in the Walther series that emits only ultraviolet light (the 5 W UV hi-power LED has a wavelength of 395 nm). UV light, also called black light, is used for checking the authenticity of bank notes and identification papers, and geocachers use it for detecting invisible marks on caches. The UV5 is supplied with three AAA alkaline batteries (1.5 V), but its multi-battery system (MBS) also allows the use of other power sources such as rechargeable batteries. Comes with battery box (3 x AAA), battery magazine for 1 x 18650 or 2x CR123, holster, lanyard and replacement seals.
