Streamlight Protac Rail Mount HL-X Laser with 18650 USB Battery

The Streamlight Protac Rail Mount HL-X Laser with 18650 USB Battery is a low-profile weapon-mounted tactical light engineered for operators who demand integrated illumination and targeting capability in a single compact unit. This hybrid system combines a 1000-lumen white LED illuminator with an integrated IR LED illuminator and visible laser, delivering multi-spectrum target engagement and identification across operational conditions from close-quarters to extended standoff ranges.

At maximum output, the white LED produces a 270-meter beam suitable for precision target work and threat assessment. The system offers dual battery compatibility: CR123A batteries deliver 45-minute runtime at high output, while the included 18650 USB rechargeable battery extends runtime to 75 minutes per charge, eliminating field battery swaps during extended operations. The USB charging standard simplifies logistics and reduces dependence on single-chemistry battery supplies. The laser and IR illuminator enable covert target marking and enhanced low-light identification without compromising white light capability, allowing operators to switch targeting modes based on tactical context.

Purpose-built for duty rifles, carbines, and short-stroke platforms, this rail-mounted configuration keeps the light system parallel to the bore while maintaining a compact 4.1-inch length and 1.14-pound weight—critical for shot dynamics on accurate fire platforms. Law enforcement patrol units, military marksmen, and serious shooters use this class of light-laser combination for target verification, positive ID in mixed lighting, and rapid threat assessment. The Protac HL-X is equally suited for training environments where integrated sighting systems help develop consistent target engagement technique.

Streamlight's modular rail-mount design accepts standard Picatinny or Weaver interfaces found on AR platforms, AK variants, precision rifle builds, and patrol carbines. The combination of white illumination, IR capability, and visible laser positioning this unit at the intersection of close-quarters work and standoff precision—a capability profile that appeals to operators managing variable-distance engagement scenarios where a single tool must span tactical distance bands.
