Surefire's 6PX Pro Flashlight is a tough solid flashlight at an affordable price. Its high-efficiency LED is virtually immune to failure since there's no filament to burn out or break and 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 one 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, abrasion, and corrosion. A polycarbonate micro-textured reflector delivers a comparatively wider beam with generous peripheral light. The mid size 6 PX Pro will be a companion for your outdoor adventures as well as emergency preparedness and everyday use.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.Max Output: 200.0 Lumens.Low Output / Runtime: 15.0 Lumens/ 45 hours.Tactical Runtime: 2.0 hours.Bezel Diameter: 1.25 in..Batteries: Two 123A.Length: 5.20".Weight w/Batteries: 5.2 oz.Made in USA..
