Streamlight ProTac Rail Mount HL-X Pro | 1,000 Lumens | 50,000 Candela | Multi-Fuel Tactical Long Gun Light

Powerful Illumination. Extended Beam Distance. Trusted Streamlight Durability.

The Streamlight ProTac Rail Mount HL-X Pro combines powerful LED illumination, long-range beam performance, and rugged construction in a compact, low-profile weapon-mounted lighting system. Designed for compatible long gun platforms, this tactical light delivers an impressive 1,000 lumens and 50,000 candela, producing a concentrated beam with a maximum rated distance of 447 meters.

Built for versatility, the ProTac Rail Mount HL-X Pro features Streamlight's innovative Jack-Cap dual-function tail cap, allowing operation through either the integrated push-button switch or a compatible remote pressure switch. This redundant switching system provides flexible control options without sacrificing the light's streamlined design.

The HL-X Pro features Multi-Fuel technology, operating on either one Streamlight SL-B26 USB-rechargeable lithium-ion battery pack or two CR123A lithium batteries. With the SL-B26 rechargeable battery, the light delivers up to 1.75 hours of runtime on high and an impressive 24 hours on low.

Streamlight's TEN-TAP Programming provides three selectable operating modes: High/Strobe, High Only, and Low/High. This programmable interface allows users to select the lighting configuration that best fits their needs.

Constructed from durable anodized aluminum with an impact-resistant tempered glass lens, the ProTac Rail Mount HL-X Pro is engineered for demanding environments. Its IP67 waterproof rating provides protection against dust and temporary water immersion when the remote pressure switch is not installed. With the remote switch installed, the light carries an IP54 water-resistance rating.

An integrated rail clamp provides secure attachment to compatible MIL-STD-1913 Picatinny rails, while the available complete system package includes additional mounting and switching accessories.

Backed by Streamlight's Limited Lifetime Warranty, the ProTac Rail Mount HL-X Pro offers a combination of high-intensity illumination, flexible power options, and dependable construction.
