The Streamlight ProTac 2.0 Rail Mount delivers 2,000 lumens of output while maintaining practical runtime, thanks to the new SL-B50 battery pack that charges via USB-C. The battery charges outside the light or while mounted on your weapon—no removal required. On high, this tactical weapon light produces 2,000 lumens with a 2.5-hour runtime and 266-meter beam distance. Low mode provides 250 lumens for 11 hours of extended runtime, and strobe capability is included. The tactical tail cap switch enables momentary or constant on operation, and three user-selectable programs are available.
This light mounts directly to 1913 Picatinny rails, ensuring compatibility across a wide range of weapons. Construction uses 6000 series machined aircraft aluminum finished with type II Mil-Spec anodized coating. The glass lens features anti-reflective coating, and the unit has been extensively live fire tested. IP67-rated protection makes it dust-tight and waterproof to 1 meter for 30 minutes. An included M-LOK mount provides alternative mounting to M-LOK and M-LOK compatible rail systems. The TEN-TAP programmable tail switch offers three selectable programs: high/strobe (factory default), high only, or low/high.
