The Streamlight ProTac Rail Mount HL-X is a high-value long-gun weapon light with serious reach — 1000 lumens and 50,000 candela for a 447m beam, plus a 60-lumen low. It ships complete with both a remote pressure switch and a push-button tail cap, with TEN-TAP programming (high/strobe, high only, or low/high).
It's dual fuel — one SL-B26 rechargeable or two CR123As — and mounts to Picatinny rails with an M-LOK mount included. Anodised aluminium, tempered-glass lens, IP67 with the push-button fitted.
