Streamlight's Super-Tac flashlight offers C4 LED technology, which delivers up to 160 lumens of intense white light for up to 3.5 hours. Perfect for illuminating repairs in hard-to-reach places, the Super-Tac's proprietary deep-dish parabolic reflector optics provide a superior long-range targeting beam as well as ample peripheral light. Powered by two, 3V CR123A Lithium batteries, Super-Tac offers one-handed operation with a tail-cap switch and comes with a holster. The upgraded Super-Tac X version also features a strobing function.
