Streamlight TLR-1 Weapon Light - White LED, Fits Picatinny & Glock-Style Rails, Aluminum Matte Finish

The Streamlight TLR-1 weapon light is a rail-mounted tactical flashlight built for handgun and rifle platforms that demand serious illumination without compromise. Whether you're running a duty pistol, home-defense carbine, or precision rifle setup, the TLR-1 attaches directly to Picatinny rails and Glock-style frames—no gunsmith required. Its compact aluminum body, matte finish, and bombproof construction make it equally at home on a nightstand gun or a serious range rig.

Brightness matters when seconds count. The TLR-1 pushes 300 lumens with a peak beam intensity of 12,000 candela, driven by Streamlight's proven C4 LED technology rated for 50,000 hours of service life. That's a concentrated beam with useful peripheral spread, courtesy of a deep-dish parabolic reflector. The light runs for 2.5 hours on a pair of CR123 lithium batteries—standard off-the-shelf power that you can stock without worry. Solid-state regulation keeps output consistent across the battery's charge cycle, so you get the same brightness whether you're 10 minutes or two hours into a mission.

Ergonomics and reliability are built in. An ambidextrous momentary/steady switch lets you manipulate the light from either side without changing your grip. The rail-grip clamp system locks down in seconds and repeats zero every time you remount it—critical if you're swapping the light between platforms or removing it for holstering. It's sealed to IPX7 spec, meaning it'll survive a dunk in water up to a meter deep for half an hour. At 4.18 ounces, it adds minimal weight and is light-bearing-holster compatible, so your carry setup doesn't need rebuilding.

This is a US-assembled tool designed by shooters for shooters. No plasma hype, no battery anxiety—just a light that works on the guns that matter.

Frequently Asked Questions

Will the TLR-1 fit my handgun?

The TLR-1 mounts directly to handguns with Glock-style rails and to any firearm equipped with Picatinny (MIL-STD-1913) rails. It includes mounting keys for Glock-style, Picatinny, Beretta 90two, S&W 99, and S&W TSW platforms. Verify your handgun has one of these rail types before ordering.

What batteries does it use, and how long do they last?

The TLR-1 runs on two standard CR123 lithium batteries, which provide 2.5 hours of regulated runtime. CR123 batteries are widely available and have a 10-year shelf life, so you can keep spares on hand without worry about degradation.

Can I use a remote switch with the TLR-1?

Yes, remote switches are available as optional accessories. They must be used with the 69130 remote door switch (sold separately). See the TLR Accessories Brochure in the documentation for compatibility details and ordering information.

Is the TLR-1 waterproof?

The TLR-1 is rated IPX7, meaning it is waterproof to 1 meter of depth for 30 minutes. It will survive incidental water exposure and normal weather, but should not be submerged intentionally beyond those limits.
