The ultra-compact, dual-output Aviator reinvents a classic SureFire design to provide a primary white LED and secondary colored LED in one sealed head, both focused into a useful beam with ample reach and surround light by a proprietary Total Internal Reflection (TIR) lens. Pull and twist Aviator’s self-locking selector ring to set it to white or colored light, no filter required-there’s even a system-disable setting to prevent accidental activation. The primary LED generates 250 lumens of smooth, intense white light on high and a user-friendly 5 lumens on low. Just press or click the shrouded tailcap switch to activate low output of the selected spectrum at momentary- or constant-on; immediately repeat to activate high output. Red improves contrast and aids in reading red-light-readable topographic maps.
