Description
The Streamlight TLR-4 is an ultra-compact, lightweight weapon-mounted light with an integrated red aiming laser designed for compact pistols such as the HK USP Compact. It uses Streamlight’s C4 LED technology to deliver a bright, focused white light rated at 170 lumens and pairs that illumination with a visible red laser for fast target acquisition. The unit provides approximately 1.5 hours of continuous runtime when used in dual mode with the high-power visible laser. A spring-loaded rail clamp enables rapid attachment and detachment from the side of the weapon.
