The Streamlight TLR-3 LED weapon light is a compact, rail-mounted option for shooters running pistols with Picatinny or Glock-style rails. Built from impact-resistant polymer with a durable anodized aluminum facecap, this light delivers 170 lumens of white LED output—enough to positively identify targets and threats in low-light scenarios without adding unnecessary bulk to your carry gun or duty weapon. At just 2.32 ounces with battery included, it won't throw off your pistol's balance or handling characteristics.

The TLR-3 uses a textured parabolic reflector to generate a concentrated beam with useful peripheral illumination, and its regulated electronics maintain consistent brightness throughout the battery's life. You get roughly 1.5 hours of continuous runtime at full output before the light drops to 10% intensity. The ambidextrous momentary and steady-on switch lets you operate the light from either side of the gun, and the one-handed snap-and-tighten rail clamp mounts and removes quickly while keeping your hands away from the muzzle—a serious safety feature when mounting or dismounting on a loaded firearm.

Runtime reliability matters in real-world use: the TLR-3 runs on a single included 3V CR2 lithium battery and operates reliably from -40°F to +120°F. The lens is borofloat glass, and the whole unit is rated IPX7 waterproof to 1 meter for 30 minutes, so you're covered in rain, snow, and splashes. A key kit is included for mounting to a variety of firearms (note: H&K USP models don't include the key kit). Assembled in the USA and backed by Streamlight's limited lifetime warranty.
