The Surefire G2ZX Tactical Flashlight is a compact yet powerful, polymer-body flashlight designed specifically for tactical use. Providing simplicity of operation and tremendous illuminating power in a small package, the G2ZX uses a high-efficiency LED that is virtually immune to failure since there's no filament to burn out or break. This light generates a brilliant, penetrating, perfectly pre-focused 600-lumen beam. The G2ZX is activated by the classic Surefire tactical tailcap switch; press for momentary-on, twist for constant-on. The tough Nitrolon polymer body is smoothly sculpted for a comfortable, secure grip and features a reduced diameter section with a rubber grip ring for additional light/handgun techniques while still providing excellent retention, even with gloved hands. The heavy duty Nitrolon body resists scratches, abrasion, and corrosion. A polycarbonate micro-textured reflector delivers a comparatively wider beam with generous peripheral light.
