The Streamlight ProTac Rail Mount HP-X Pro USB Long Gun Light Kit delivers an impressive 800 lumens and 105,000 candela along with multi-fuel versatility and multiple mounting options. The HP-X Light is capable of throwing its beam out to 648 meters, illuminating the darkest corners and penetrating fog, smoke, and photonic barriers. Made from 6000-series aluminum, it mounts to both MIL-STD-1913 Picatinny rails and M-LOK sections, giving you plenty of versatility in mounting. The multi-fuel system operates on either the included SL-B26 rechargeable battery or two CR123A batteries (not included). The Jack-Cap tail switch gives you additional redundancy with push-button operation on top of the pressure switch. TEN-TAP programming lets you customize your operation modes. The HP-X is 100% waterproof to IPX-7 standards on its own and water-resistant to IPX-4 standards with the remote switch installed.
