The ProTac 1AAA hand-held light uses one easily sourced AAA alkaline battery and delivers up to 70 lumens measured system output and 550 candela peak beam intensity. Compact and versatile, the ProTac 1AAA also offers high- and low-intensity modes, a strobe feature, and the latest in C4® LED technology. Its Ten-Tap® programmable switch allows users to select one of three programs: high/low/strobe (the factory default), high only, or low/high. The light delivers 30 minutes of continuous run time on high over a beam distance of 47 meters, 11 hours on low and 1.2 hours in strobe mode using an alkaline battery. For an extended run time, a lithium-AAA battery can be used. The light uses a C4 LED with a 50,000-hour lifetime, which is impervious to shock. It features 6000 Series machined, aircraft-aluminum construction with an anodized finish and includes a convenient multifunction, push-button, tactical tail-cap switch for easy, one-handed operation of the momentary, variable-intensity, or strobe modes.
