Streamlight ProTac Rail Mount 1L-X Pro USB 850 Lumens Weapon Light

The Streamlight ProTac Rail Mount 1L-X Pro USB is a compact, high-output weapon-mounted tactical light engineered for short-barreled rifles, carbines, and submachine guns. Built around a ruggedized rail-mount housing, this light delivers 850 lumens of intense white LED output on high when powered by the included SL-B9 USB-rechargeable Li-ion battery pack, throwing a focused beam out to 346 meters with a peak intensity of 30,000 candela.

Engineered around Streamlight's multi-fuel platform, the ProTac 1L-X Pro USB accepts either the SL-B9 rechargeable battery pack or a single CR123A lithium cell. With the SL-B9 installed, the light produces 850 lumens for 0.5 hours of runtime; with a CR123A cell, output is set to 500 lumens at 18,000 candela with a 268-meter beam for 1.75 hours. The low setting delivers 100 lumens at 3,400 candela with a 117-meter beam and up to 4.5 hours of runtime, ideal for navigation, map reading, and administrative tasks.

The black anodized housing measures just 4.64" long by 1.37" wide and 1.72" tall, giving the ProTac 1L-X Pro USB a compact footprint on the host weapon. The integrated rail-clamp system provides a secure mounting solution. The 89025 ships with the SL-B9 USB-rechargeable battery pack.
