Streamlight TLR-1s 300 Lumen Strobe Weapon Light

The Streamlight TLR-1s is a black rail-mounted weapon light that produces 300 lumens, 12,000 candela, and a 219 m beam. It runs for up to 2.5 hours on two CR123A lithium batteries and adds a user-programmable strobe to the standard TLR-1 switching system. A weapon light in this output class is intended to combine target-area illumination with quick access to controls from the mounted position.

The machined aluminum body mounts to supported Glock-style and 1913 Picatinny rails with the included locating keys. Ambidextrous controls provide momentary or constant operation, and the IPX7-rated housing is waterproof to 1 m for 30 minutes. A sealed aluminum housing and purpose-built controls are practical features for equipment that may see regular range, field, or duty use.

Battery type and runtime are worth considering alongside maximum output because they determine how the light fits the user's maintenance routine. The finish on this version also gives buyers a way to coordinate the light with the rest of the host equipment without changing the basic operating platform. For a permanent mounted setup, keeping spare batteries and verifying mounting hardware periodically are sensible parts of routine equipment care. The TLR-1s version adds a selectable strobe function while staying within the familiar TLR-1 rail-mounted platform. Browse more weapon lights.
