Go With The Game Changer. The 6PX Pro traces its origins directly to the SureFire 6P that introduced the compact, high-efficiency flashlight in 1988. Its LED provides two light output levels: a brilliant, penetrating, perfectly pre-focused 600-lumen beam and a 15-lumen low-output setting that lets you greatly extend the runtime per set of batteries. Its tail cap offers momentary-on low, constant-on low and constant-on high. Its high-strength aerospace aluminum body is sculpted for a secure grip and Mil-Spec hard anodized for scratch, abrasion and corrosion resistance. Its polycarbonate micro-textured reflector delivers a comparatively wider beam with generous peripheral light. The 6PX Pro does the family proud.
