The Nightstick TAC-300 Series is a set of non-rechargeable polymer or metal LED tactical flashlights that outperforms most other lights that cost twice as much. Four models are included in the series...the TAC-300 (B, T & Y) and the TAC-350B. With a CREE® LED rated at 180 lumens, combined with a high-efficiency deep parabolic reflector, the TAC-300 Series' beam has an effective range of 190 meters (over 620 feet). A waterproof design in combination with an impact and chemical resistant glass-filled nylon polymer housing (300s) or an aircraft-grade 6061-T6 aluminum housing (350), make the TAC-300 Series one of the toughest set of 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 Series lights are rated at 3 hours of run-time.
