The G2X Pro is a compact yet powerful polymer-body flashlight that features a high-efficiency LED - virtually immune to failure since it has no filament to burn out or break. It provides two light output levels: a bright, penetrating, perfectly focused 600-lumen beam, and a 15-lumen low-output setting that significantly extends runtime per set of batteries. This is an essential option when you're far from civilization. Press the tail cap switch for momentary low, press further to turn on constant low, return to off, and press or click again within two seconds for high. The durable Nitrolon polymer body is smoothly designed for a comfortable, secure grip and resists scratches, abrasion, and corrosion. A polycarbonate micro-textured reflector delivers a wider beam with ample peripheral light.
