Go With The Game Changer. The 6PX Pro traces its origins directly to the SureFire 6P that introduced the compact, high-efficiency flashlight in 1988. Its LED provides two light output levels: a brilliant, penetrating, perfectly pre-focused 600-lumen beam and a 15-lumen low-output setting that lets you greatly extend the runtime per set of batteries. Its tail cap offers momentary-on low, constant-on low and constant-on high. Its high-strength aerospace aluminum body is sculpted for a secure grip and Mil-Spec hard anodized for scratch, abrasion and corrosion resistance. Its polycarbonate micro-textured reflector delivers a comparatively wider beam with generous peripheral light. The 6PX Pro does the family proud.Specifications, key features, and additional product informationFeatures 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 High-strength aerospace aluminum body, Mil-Spec hard-anodized for extreme durability 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 O-ring and gasket sealed for waterproof, weatherproof reliability Includes high-energy 123A batteries with 10-year shelf life Key Attributes HIGH OUTPUT 600 lumens HIGH RUNTIME 1.5 hours PEAK BEAM DISTANCE 8,700 candela BATTERIES Two 123A (incl,) SWITCHING Click tailcap Output LOW OUTPUT 15 lumens LOW RUNTIME 52 hours DISTANCE 187 meters Body CONSTRUCTION Aluminum FINISH Mil-Spec Hard Anodized LENGTH 5.2 in (13.2 cm) WEIGHT WITH BATTERIES 5.2 oz (147 g) BEZEL DIAMETER 1.25 in (3.175 cm) LIQUID INGRESS PROTECTION IPX7 California Proposition 65 WARNING: This product can expose you to chemical(s) known to the State of California to cause cancer, birth defects or other reproductive harm.
