Streamlight ProTac Rail Mount HP-X Pro Features The Streamlight ProTac Rail Mount HP-X Pro is built for extreme beam reach delivering 105 000 candela and a maximum beam distance of 648 meters letting shooters identify targets and obstacles well beyond typical weapon light range. The light is multi-fuel accepting either a Streamlight SL-B26 protected lithium ion rechargeable battery pack or two CR123A lithium batteries giving users flexibility based on what power source is available. TEN-TAP programming allows selection between three different operating modes high and strobe high only or low and high letting the user match the light s behavior to the mission at hand. The Jack-Cap tail switch features both a push button switch and a port for a remote pressure switch giving operational redundancy if one switch method fails or is inconvenient to reach. Constructed from 6000 series machined aircraft aluminum with an anodized finish the ProTac Rail Mount HP-X Pro is built to handle the recoil and rough handling of long gun use over years of service. The light carries an IPX7 waterproof rating with the standard push button switch installed and an IPX4 water resistant rating when the remote pressure switch is in use along with 2 meter impact resistance testing for added durability. An included M-LOK mount allows direct attachment to MIL-STD-1913 rail equipped long guns or M-LOK handguards without needing a separate adapter purchased. For long gun owners who need a light capable of throwing a far reaching bright beam in low light or nighttime conditions the Streamlight ProTac Rail Mount HP-X Pro delivers that performance.
