New R6 version: This item replaces our R5 version 365nm flashlight: 1030mW UV output from the latest Nichia UV emitter -- previous R5 version was 780mW! This light produces 1000uW/cm2 at 15" of output with a smooth diffuse beam, now with high quality quartz diffuser (compared to glass used in the R5).
Powered by 2xCR123A cells (included) also operates with 1x18650 rechargeable LiIon cell, as do many of our other flashlights.
Tailcap switch, o-ring sealed, glass lens, latest Nichia 365nm emitter. Kit includes 2xCR123A batteries, U50 yellow viewing glasses, and case. U50 viewing glasses are superior to the economy yellow viewing glasses, and are made in USA.
Compared to the discontinued 8-LED flashlight and R5 models, wavelength is the same (365nm) and spectral width is the same (10nm FWHM). Intensity and beam width have been improved.
