This 1 AA Mini-TAC Pro light uses a deep parabolic reflector creating a tight, long-throw beam for distance illumination. With a waterproof design, it is constructed from aircraft-grade 6061-T6 aluminum with a Type III hard-anodized finish. The tail switch provides momentary or constant-on functionality, a set of user-selectable high, medium, or low-brightness settings as well as a disorienting strobe. The light comes with a removable pocket clip and is powered by an included AA battery.
