Streamlight TLR-3X USB 500-Lumen LED Weapon Light - 1913 Rail

The Streamlight TLR-3X USB is a compact rail-mounted weapon light purpose-built for subcompact and compact handguns equipped with a MIL-STD-1913 (Picatinny) rail. Built around a rugged polymer housing in a low-profile black finish, the TLR-3X USB delivers 500 lumens of white LED output with a peak intensity of 6,500 candela and a 161-meter beam distance, providing plenty of throw for positive threat identification at typical defensive ranges.

At the heart of the light is a high-output white LED rated for a 50,000-hour lifetime, paired with a reflector that produces a bright central spot with usable spill for close-quarters navigation. The TLR-3X USB is a true multi-fuel design: it ships with the SL-B9 USB-C rechargeable Li-Ion battery pack for everyday convenience, and it also accepts a standard CR123A lithium primary cell for backup or field use without the rechargeable pack.

On the included SL-B9 USB rechargeable pack, the TLR-3X USB runs for up to 1.5 hours of regulated output. The light clamps securely to the host handgun's 1913 rail, keeping the activation controls within easy reach of the support-hand thumb. Total weight is just 2.15 ounces with a battery installed, so the TLR-3X USB adds minimal bulk to a carry pistol while improving low-light capability.

The TLR-3X USB represents a modern direct upgrade to the original TLR-3 platform, combining significantly higher output, a rechargeable power option, and proven rail-mounted durability into one compact, lightweight package.
