Building off the success of our acclaimed Expedition series, the Expedition Star introduces the latest in LED technology—the Luxeon Star LED. Military tested tough. The same model as supplied to the military. This Luxeon Star LED flashlight utilizes specialized optics to produce an ultra-tight 10-degree beam pattern, with a light output equivalent to more than 20 regular LEDs. This "spot" beam pattern enables the Expedition Star to cut through fog and smoke. Burn time is 15+ hours at full power with an additional 50 hours of usable light. Double O-ring seals give this waterproof light an underwater depth rating of 500 feet. Comes with an adjustable, cushioned wrist lanyard and rubber glare guard
