The Surefire P2X Fury flashlight uses a high-efficiency, virtually failure-proof LED to deliver your choice of either 15 or 600 lumens of perfectly focused light, the latter qualifying the Fury as a pocket-sized searchlight. The 15-lumen level is excellent for general work at close-to-medium distances, and also lets you greatly extend the runtime per set of batteries, a valuable option when you're miles from civilization. At either setting the high-strength polymer micro-textured reflector delivers a smooth, comparatively wide beam with a brighter central area and generous peripheral light. The Fury is activated with a click-type tailcap switch: press for momentary-on low, press further to click constant-on low; return to off and press or click on again within two seconds for high. The high-strength aerospace aluminum body is knurled for a comfortable, secure grip and is hard anodized to military specifications for extreme resistance to scratches, abrasion, and corrosion.
