The SureFire G2X Pro flashlight is a compact yet powerful polymer-body flashlight that uses a high-efficiency LED to provide two light output levels: a brilliant, penetrating, perfectly pre-focused 600lumen beam and a 15-lumen low-output setting that allows for extension of runtime per set of batteries. The polycarbonate microtextured reflector delivers a comparatively wider beam with generous peripheral light. The tough Nitrolon polymer body is smoothly sculpted for a comfortable, secure grip, and it resists scratches, abrasions, and corrosion. The tailcap switch is pressed for momentary-on low and clicked for constant-on low. After returning to off, the switch can be pressed or clicked again within 2 seconds for high.
