Smith & Wesson Powertech 5 Watt CREE LED Tactical Flashlight SW733LX is most notable for its exceptional brightness. The Luxeon LED Rebel 80 bulb provides the long-lasting bulb life of an LED with the brightness (100 lumens) and intensity of a conventional high powered bulb (brighter than most 5 D-Cell Flashlights!). With over 10,000 hours of bulb life, this Power Tech Luxeon LED flashlight by S&W is built to last a lifetime and uses only two CR123 batteries to operate. The constant current circuitry in this flashlight will not fail to give you light whenever or wherever you need it. This Smith & Wesson Flashlight is constructed of precision 6061 anodized aluminum for superior corrosion resistance, 'O-ring' sealed, and with a shatterproof, polycarbonate lens, this flash light is fire, water, scratch, and impact resistant. Its limited lifetime warranty guarantees that its buyers will find the quality and durability they have come to expect from Smith & Wesson.
