This compact rechargeable 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. 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.
