Streamlight's compact ProTac 1L Professional Tactical light is a compact, multi-functional flashlight designed with Ten-Tap programming for quick adjustment between high, low and strobe settings. The high setting emits a 275-lumen heavy-duty beam, and the low setting operates at a lower battery consumption rate producing a 22-lumen beam, which has an impressive 24-hour runtime. C4 LED technology allows for precise beam concentration that can illuminate a large room or alley with ease, and stays waterproof up to one meter for 30 minutes. This compact model features a push-activated switch on the tailcap for quick, ambidextrous use, as well as an anti-roll head to prevent accidental falls. The stress-resistant pocket clip and nylon holster make for easy carry and convenient concealment.
