Streamlight ProTac 2.0 Rail Mount Long Gun Light Weapon Light 2000 Lumens Black

The Streamlight ProTac 2.0 Rail Mount Long Gun Light Weapon Light delivers 2000 lumens of tactical illumination without sacrificing runtime on extended operations. Powered by the proprietary SL-B50 protected lithium-ion USB-rechargeable battery pack, this rail-mounted weapon light is engineered for law enforcement, military, and serious shooters who demand consistent performance across high-round-count training sessions and duty scenarios. The included battery charges via USB-C directly in the light—no removal required—ensuring operators stay mobile and ready.

Tactical lighting performance hinges on both raw output and selectable functionality. The ProTac 2.0's 2000-lumen peak intensity provides identification and target engagement capability across indoor and outdoor environments typical of patrol, breaching, and range work. The TEN-TAP programming system offers three user-selectable modes: high/strobe, high only, or low. This flexibility allows operators to dial in appropriate light levels for threat assessment while preserving situational awareness, and the strobe mode serves defensive purposes when needed. The SL-B50 battery pack's protected circuitry and USB-C charging ecosystem represent modern power management—a shift away from proprietary chargers that slows field operations.

This weapon light is purpose-built for long guns mounted via Picatinny rail systems. Duty-oriented users—tactical teams, patrol officers, and precision rifle shooters—rely on rail-mounted illumination to maintain sight picture and control without hand-held light management. The compact footprint (4.1 x 2.85 x 8.1 inches, 0.92 lbs) preserves balance and handling characteristics while mounting forward or rear on the receiver. For shooters running accessory-heavy platforms or transitioning between equipment setups, the Streamlight ProTac 2.0 delivers the output and reliability required for mission-critical work without unnecessary bulk.
