The SR51 Intimidator is a search and rescue flashlight designed to provide strong reach and illumination in a compact package.  Its CREE XM-L U2 LED throws an impressive 900 lumens to almost 1,600 ft. The hard-anodized aircraft-grade aluminum body houses 6 x CR123A batteries. Batteries not included.  Yet the incredibly tough SR51 still remains handy and portable with long run time for search and rescue or even tactical missions.  The side switch selects between two brightness levels, a strobe mode, and a lock-out function to prevent accidental activation.  It remembers your last brightness setting and offers quick access to the strobe mode.  The SR51 simply does it all. The product comes with beautiful aluminium carry case.
