Overview

The Streamlight ProTac Rail Mount HL-X represents exceptional value in the weapon light category, delivering 1,000 lumens with 50,000 candela and 447-meter beam distance at a fraction of the cost of premium alternatives. This dual-fuel light accepts either a Streamlight SL-B26 rechargeable battery (1,300 lumens) or two CR123A batteries (1,000 lumens), providing operational flexibility without sacrificing performance. The TEN-TAP programming allows users to select between three operating modes: high/strobe, high only, or low/high.

Constructed from 6000 series aluminum with a black anodized finish, the ProTac HL-X features an integrated rail clamp that makes it easy to attach to Picatinny and M-LOK rail systems. The included M-LOK adapter and pressure switch make this a complete package ready for installation—no additional purchases required. While not dive-rated, the light's IPX rating makes it capable for outdoor use, and user reports confirm reliable operation after exposure to muzzle residue, mud, and temperature extremes.

At approximately $100-130 street price, the ProTac HL-X competes directly with lights costing two to three times more. Users consistently praise its brightness, durability, and included accessories. For those seeking a reliable weapon light without the premium price tag, the ProTac HL-X delivers professional-grade performance that punches well above its weight class.
