This compact rechargeable multi-function metal 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 m. 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 and tail-cap are made from aircraft grade 6061-T6 aluminum and have a type III hard anodized finish. 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 CR123 battery carrier (included).
