The Streamlight ProTac Rail Mount HL-X Pro USB is a compact, long-range light designed to deliver dependable white light on your rifle or carbine. Producing up to 1,000 lumens with a focused 50,000 candela beam, it reaches out to 447 meters while still providing generous spill for situational awareness. Multi-fuel capability lets you run the included SL-B26 USB rechargeable battery pack or swap to CR123A lithium cells, and the Ten-Tap programmable interface tailors the light’s output to your preferred mode sequence.

This model’s low-profile body mounts directly to Picatinny or M-LOK rails and includes both a push-button tailcap and remote pressure switch for flexible activation. With high, low, and strobe modes plus long runtimes up to 24 hours on low, it is well suited for home protection setups, range training, and general-purpose rifle use. Streamlight’s proven engineering and durable aluminum construction make the ProTac Rail Mount HL-X Pro USB a reliable lighting solution for demanding users.
