Streamlight TLR-1 — Rail-Mounted Weapon Light

Streamlight TLR-1 Weapon Light - 300 Lumens

Get the gold standard in duty-grade illumination with the Streamlight TLR-1 — an intensely bright, virtually indestructible rail-mounted tactical light that attaches to almost any handgun or long gun in seconds, no tools required.

C4 LED technology delivers up to 300 lumens and 12,000 candela of peak beam intensity, with a deep-dish parabolic reflector producing a concentrated beam and optimum peripheral illumination — genuinely useful for both threat identification and navigating low-light environments. Powered by two 3-volt CR123 lithium batteries with a 10-year storage life, this light delivers 2.5 hours of solid-state regulated run time, keeping illumination consistent from the moment you activate it until the battery is genuinely spent, rather than gradually dimming.

The rail grip clamp system securely attaches and detaches quickly and safely without tools, and without putting your hands in front of the muzzle — a real safety consideration during mounting or removal. It mounts directly to firearms with Glock-style rails as well as all MIL-STD-1913 (Picatinny) rails, giving you broad compatibility across handguns and long guns alike. The machined aircraft aluminum housing is genuinely built to be shock-resistant and rugged, backed by Streamlight's "No Excuses" Limited Lifetime Warranty.

Whether you're equipping a home-defense handgun, outfitting a duty weapon, or need dependable weapon-mounted illumination for low-light hunting or field use, the Streamlight TLR-1 delivers the trusted, duty-proven performance that's made it one of the most widely adopted weapon lights on the market.
