This compact rechargeable multi-function polymer Xtreme Lumens™ tactical flashlight uses an LED rated at 800 lumens that works in conjunction with a high-efficiency deep parabolic reflector to create a usable beam rated at 205 meters. The tail-cap switch provides momentary or constant-on functionality, a set of user-selectable high, medium or low-brightness settings as well as a disorienting strobe. The housing is made from glass-filled nylon polymer. Power comes from a rechargeable Lithium-ion battery and includes the ability to run from a pair of CR123 batteries (batteries not included) thanks to the optional CR123 Battery Carrier. Not compatible with CR123-style rechargeable batteries.
