Press the tailcap switch for momentary-on low, press further to click constant-on low, return to off and press or click on again within two seconds for high. 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. We also make an aerospace aluminum-body version of this light, the 6PX Pro, and a single-output version with a tactical tailcap switch, the G2X Tactical. Features Virtually indestructible LED emitter regulated to maximize light output and runtime Two output levels—high for maximum light, low for extended runtime Precision micro-textured reflector creates smooth, optimized beam Tough polycarbonate window resists impact Tough Nitrolon® body, anodized aluminum bezel Dual-output tailcap click switch—press for momentary-on low, click for constant-on low, return to off then press or click again for high Weatherproof—O-ring and gasket sealed Includes high-energy 123A batteries with 10-year shelf life
