Surefire AZ2-S CombatLight Dual-Output All-Aluminum LED Flashlight w/ Strobe provides two distinct beams of light at different output levels, and features a high-output tactical strobe designed to disorient an aggressor or to be used as an emergency beacon. And it all comes packaged in the rugged SureFire CombatGrip body. The dual-setting Surefire A-Z2 Flashlight uses virtually indestructible power-regulated LED emitters and a precision micro-textured reflector to produce both spot and flood beams. LED Flashlights are virtually immune to failure since there's no filament to burn out or break.This tough little Surefire Flashlight meets the requirements of a primary light (when used with a V85A holster, sold separately), but is ideal for anyone who wants to carry a powerful, versatile flashlight. The Surefire AZ2S Tactical Light has a two-stage pushbutton tailcap switch that lets you instantly select an output level: press for a momentary-on 35-lumen long-runtime flood beam; press further for a momentary-on 150-lumen tactical spot beam-over seven times the light output of a big two-D-cell flashlight; twist for constant-on low, twist further for constant-on high. To activate the strobe, press the tailcap three times rapidly. The Sure Fire AZ2 CombatLite Flashlight has a patented CombatGrip body which improves performance with various flashlight/handgun techniques, such as the Rogers/Sure Fire technique, and provides a secure hold in wet or cold conditions or while wearing gloves.
