The Surefire G2X Pro Flashlight is a compact yet powerful polymer-body flashlight that can crank out 320 lumens on demand. This tactical light uses a high-efficiency LED bulb and has 2 light output levels: a brilliant, penetrating, perfectly pre-focused 320-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. A polycarbonate micro-textured reflector delivers a comparatively wider beam with generous peripheral light. The Surefire G2X Pro Tactical Flashlight is built with a tough Nitrolon polymer body, smoothly sculpted for a comfortable, secure grip, and highly resistant to scratches, abrasion and corrosion.
