No need to click a button or twist a bezel—with the SureFire Fury IntelliBeam Dual-Fuel LED Flashlight, you'll always have the light you need for the task at hand. The flashlight evaluates the scene and adjust light output accordingly, from a low of 15 to a peak of 1500 lumens. You have the option of overriding the auto-adjust, going straight to peak output with two clicks of the tailcap push-button switch. Power is supplied by the included 3.6V 18650 battery, fitted with a micro-USB recharging port.The light can also run on two CR123A batteries, with a peak output of 1100 lumens. Maximum runtime is 40 hours.

The Fury-IB-DF uses a precision micro-textured reflector for a smooth beam with a bright central area and enough surround light for situational awareness. Its O-ring-sealed, hard-anodized aluminum body is knurled for a comfortable grip, and the lens is crafted from tempered glass.
