The SureFire 6PX Pro Dual-Output Tactical LED Flashlight’s high-efficiency LED, virtually immune to failure since there’s no filament to burn out or break, provides two light output levels - a brilliant, penetrating, perfectly pre-focused 200 lumen beam, and a 15 lumen low-output setting that lets you greatly extend the runtime per set of batteries, an invaluable option when you find yourself miles from civilization. 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 high strength aerospace aluminum body is smoothly sculpted for a comfortable, secure grip and is hard anodized to military specifications for extreme resistance to scratches, abrasions and corrosion. A polycarbonate micro-textured reflector delivers a comparatively wider beam with generous peripheral light. •High-strength Aerospace Aluminum body •MIL-SPEC hard anodized for extreme durability •Virtually indestructible LED emitter regulated to maximize light output and runtime •Precision micro-textured reflector creates smooth, optimized beam •Tough Polycarbonate window resists impact •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 •Requires two "123A" battery (Included) •MAXIMUM OUTPUT: 200 lumens •MINIMUM OUTPUT: 15 lumens •TACTICAL RUNTIME: 2 hours •LOW OUTPUT RUNTIME: 45 hours •BEZEL DIAMETER: 1.25" •LENGTH: 5.2" •WEIGHT w/BATTERIES: 5.2 oz. •Imported
