The Z2 LED is a compact high-output flashlight featuring a CombatGrip body. It uses a virtually indestructible power-regulated LED and a precision micro-textured reflector to produce a smooth 120-lumen beam—six times the light of a big two-D-cell flashlight, and more than enough to temporarily blind and disorient an aggressor by impairing his night-adapted vision. The tactically-correct pushbutton tailcap switch provides secure, ergonomic activation control: press for momentary-on, twist for constant-on. The Z2 LED's patented CombatGrip body improves performance with various flashlight/handgun techniques, such as the Rogers/SureFire technique, and provides a secure hold in wet or cold conditions or while wearing gloves. Features Virtually indestructible LED emitter regulated to maximize output and runtime Precision micro-textured reflector creates smooth, optimized beam Coated tempered window resists impact, maximizes light CombatGrip for secure hold in all conditions High-strength aerospace aluminum body, anodized for durability Tactical tailcap switch—press for momentary-on, twist for constant-on Weatherproof O-ring and gasket sealing Includes high-energy 123A batteries with 10-year shelf life
