Providing simplicity of operation and tremendous illuminating power in a small package, it uses a high-efficiency LED--virtually immune to failure since there's no filament to burn out or break--to generate a brilliant, penetrating, perfectly pre-focused 200-lumen beam. The 6PX is activated by our classic tactical tailcap switch--press for momentary-on, twist for constant-on. The high-strength aerospace aluminum body is smoothly sculpted for a secure grip and is hard anodized to military specifications for extreme resistance to scratches, abrasion, and corrosion. A polycarbonate micro-textured reflector delivers a comparatively wider beam with generous peripheral light.
