The Nightstick TAC-300 is a non-rechargeable LED Tactical Polymer Flashlight that outperforms most other lights that cost twice as much. With a CREE LED rated at 180 lumens and its high-efficiency deep parabolic reflector, the TAC-300s beam has an effective range of 190 meters over 620 feet . Its waterproof design in combination with its impact and chemical resistant glass-filled nylon polymer housing, make the TAC-300 one of the toughest tactical lights around. The large tail-cap switch provides momentary or constant-on light operations. Running on a pair of included CR-123 Lithium batteries, the TAC-300 is rated at 3 hours of run-time.
