Convoy C8 UVC Flashlight 255nm Shortwave with Extension Tube

The Convoy C8 UVC flashlight emits 255nm shortwave ultraviolet light, the classic wavelength for mineral fluorescence. Many minerals that stay dull under a 365nm longwave light glow brightly under shortwave, such as scheelite (bluish white), willemite (green) and many calcites. It uses the same grey C8 body as our other Convoy lights, with a large head and an extension tube so you can run it on one or two 18650 batteries. Convoy's own LED test report for this model shows a peak at 256nm with about 112mW of UV output, which is a real shortwave source in a handheld size. Features: Wavelength: 255nm UVC (shortwave), measured peak 256nm UV output: about 112mW radiant flux (manufacturer's LED test) Filter: ZWB3 glass, lets the UV through and holds back most visible light Material: anodized aluminium alloy, grey finish Extension tube included: runs on 1x or 2x 18650 batteries (not included) Large reflector head for a wide UV spot Tail lanyard holes for a wrist strap Ideal for: Shortwave fluorescence of minerals such as scheelite, willemite and calcite Mineral prospecting and sorting specimens at night Comparing a specimen under longwave and shortwave UV Not sure which UV flashlight is right for you?
