Compact (pocket sized), high-intensity incandescent flashlight for self-defense and general use. Produces a smooth, brilliant, pre-focused tactical-level beam with three times the light of a big two-D-cell flashlightâbright enough to temporarily blind and disorient a person by impairing his night-adapted vision. Small size and high output make it a perfect everyday-carry light. SureFire's incandescent pocket powerhouse.
