This innovative, automatically adjusting version of the original P2X Fury takes full advantage of the variable-output capability of one of SureFire’s brightest and most popular LED flashlights. Our proprietary IntelliBeam™ Technology—an intelligent sensor and microprocessor-based system—continuously evaluates your environment and seamlessly adjusts light output, from 15 up to 600 lumens, based on the scope of your surroundings. Just press or click its tailcap switch to access this auto-adjusting mode, which delivers just the right amount of light output. Return to off and press or click again within one second to activate max-output/tactical mode, which locks in all 600 lumens—ideal when maximum output is what you need. The P2X Fury with IntelliBeam Technology—like all other Fury models—uses a high-performance LED to deliver its perfect light that’s focused by a parabolic reflector into a smooth, comparatively wide beam with a bright central area and generous peripheral light.
