The Streamlight TLR-1S LED weapon light is a compact, hard-use mounted light built for pistol and rifle shooters who need reliable illumination without unnecessary bulk. Whether you run a Glock-pattern handgun, AR platform, or any gun equipped with Picatinny rails, the TLR-1S attaches tool-free in seconds and delivers serious output: up to 300 lumens with 12,000 candela peak intensity. That's enough to light up a room or a shooting range, with a deep-dish parabolic reflector that creates a concentrated beam plus usable peripheral illumination for close-quarters work.
Built on Streamlight's proven C4 LED technology, the TLR-1S is designed to handle the recoil and shock of live fire without dimming or degrading. Two CR123A lithium batteries power the light for up to 2.5 hours of regulated runtime, and the solid-state current regulation keeps brightness consistent throughout that entire window. The batteries themselves are rated for 10-year storage life, so your light won't be dead when you need it. At just over 4 ounces and finished in durable anodized aluminum, the TLR-1S sits low and tight on the rail, minimizing snag risk and maintaining sight picture repeatability shot after shot.
The paddle switch is ambidextrous and gives you momentary or steady-on control. Double-tap the momentary button in 0.4 seconds to activate strobe mode—a proven tactic for disorienting threats or cutting through darkness and dust. The housing is sealed to IPX7 standards, meaning it'll survive a dunking to 1 meter for half a minute. This is a light built for duty, training, and serious sport shooting, backed by Streamlight's reputation for simplicity and reliability.
