Streamlight ProTac Rail Mount 1L-X USB Pro Weapon Light

The Streamlight ProTac Rail Mount 1L-X USB Pro is the rechargeable member of the new 1L-X Pro pair. It produces 850 lumens and 30,000 candela from a compact black body intended for 1913 Picatinny rails. Compared with the CR123A version, this model raises both output and beam intensity while moving to the included SL-B9 rechargeable pack.

The package includes a USB charger, jack cap, M-LOK kit, momentary switch, hardware kit, and 2.5mm Allen wrench. That gives the buyer the power, switching, and mounting pieces needed for the listed setup without building the package one accessory at a time. Because Streamlight describes the light as multi-fuel, the rechargeable pack is the supplied power option rather than the only reason to choose the model.

Model 89025 is the better fit when USB rechargeable power is preferred and the extra 350 lumens over the 89024 model are useful. The host still needs a compatible rail or handguard, so the included mounting pieces should be checked against the firearm before installation.
