The Nightstick TAC-400 is a rechargeable LED Tactical Polymer Flashlight that outperforms most other lights that cost twice as much. With an LED rated at 200 lumens and its high-efficiency deep parabolic reflector, the TAC-400s beam has an effective range of 210 meters (over 688 feet). Its waterproof design in combination with its impact and chemical resistant glass-filled nylon polymer housing, make the TAC-400 one of the toughest tactical lights around. The large tail-cap switch provides momentary or constant-on light operations. Running on a Lithium-ion rechargeable battery, the TAC-400 is rated at 3 hours of run-time.
