SureFire's 6PX Tactical LED flashlight is designed specifically for tactical use, and it uses a high-efficiency LED to generate a brilliant, penetrating, perfectly pre-focused 320-lumen beam. The polycarbonate micro-textured reflector delivers a comparatively wider beam with generous peripheral light. The high-strength aerospace aluminum body is smoothly sculpted for a secure grip, and it is hard-anodized to military specifications for extreme resistance to scratches, abrasion, and corrosion. The tactical tailcap switch can be pressed for momentary-on or twisted for constant-on, and the 6PX Tactical is O-ring and gasket-sealed for weatherproofing.
