The single-output G2ZX CombatLight by SureFire was designed and built specifically for tactical use. The high-performance LED produces 320 lumens of brilliant white light, and the micro-textured polycarbonate reflector creates a smooth beam with optimal light distribution. The tough Nitrolon polymer body provides superior scratch, corrosion, and abrasion resistance. The CombatGrip design, with a reduced-diameter mid-section and rubber grip ring, is perfect for flashlight/handgun techniques and provides a secure hold even with wet, cold, or gloved hands. The tactical tailcap switch can be pressed for momentary-on or twisted for constant-on, and the G2ZX CombatLight is O-ring and gasket-sealed for weatherproofing.
