Streamlight's compact ProTac HL USB is a lightweight, programmable tactical light that emits a high-power 1000-lumen beam, visible at 200 meters. It incorporates intuitive Ten-Tap programming to adjust between three settings, each of which produces a different level of light. The high setting emits the 1000-lumen heavy-duty beam, but the flashlight can be set to an 80-lumen low setting, which has a 12-hour runtime. C4 LED technology provides maximum illumination for any situation, and is shock-resistant as well. This compact model also features a push-button switch at the tail and an anti-roll head, making one-handed operation simple. The aluminum construction and O-ring sealed tempered glass lens are ultra-durable, and come with a removable pocket clip and nylon holster for easy carry.
