The Fury IntelliBeam is in a class by itself, a versatile pocket searchlight that can adapt to meet your lighting needs on the fly. It takes the 1,500-lumen capability of the Fury DFT and adds SureFire's proprietary IntelliBeam circuitry. IntelliBeam automatically and seamlessly adjusts output to the optimal setting — between 15 and 1,500 lumens — based on your environment. Or you can simply double click the tailcap to override the auto-adjustment function. No hesitation. No fumbling to manually set the output. Count on the Fury Intellibeam to keep you calm in tense circumstances.
