Compact penlight with both white light and UV light. UV-LED enables extended functions, e.g. leak detection, banknote or document checking. The UV light can either be on permanently or blink slowly so that fluorescent areas stand out better against the rest of the background. Lamp body made of aircraft aluminum. Detachable metal clip for easy attachment to belt or pocket. Light effect in three brightness levels. Additional UV LED with a wavelength of 365 nm for continuous light or 5 Hz flashing. Can either be used with two AAA alkaline batteries or two AAA NiMH rechargeable batteries.
