Features and benefits: virtually indestructible led emitter regulated to maximize light output and runtime precision micro-textured reflector creates smooth, optimized beam tactical tailcap switch-press for momentary-on, twist for constant-on tough nitrolon body, anodized aluminum bezel includes high-energy 123a batteries with 10-year shelf life the g2x tactical, a polymer-body version of our 6px tactical, is designed specifically for tactical use. Providing simplicity of operation and tremendous illuminating power in a small package, it uses a high-efficiency led-virtually immune to failure since there's no filament to burn out or break-to generate a brilliant, penetrating, perfectly pre-focused 200-lumen beam. The g2x is activated by our classic 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 resists scratches, abrasion, and corrosion. A polycarbonate micro-textured reflector delivers a comparatively wider beam with generous peripheral light.
