The Streamlight TLR-4 Weapons Light with Red Laser is a lightweight and compact rail-mounted light designed to fit compact and sub-compact handguns as well as full-sized handguns. The Streamlight TLR-4 is made from impact-resistant polymer to ensure durability.

The Streamlight TLR-4 is powered by C4 LED technology which delivers 5,300 candela peak beam intensity up to 125 lumens. One 3V CR2 lithium battery ensures 1.5 hours of runtime for LED only or LED laser with 11 hours of runtime for the laser only. This tactical light also includes a textured parabolic reflector which produces a concentrated beam for optimal peripheral illumination.
