This intrepid tactical light source is discreet and stealthy until you need it, thanks to the matte black finish on its anti-roll aircraft aluminum housing. And then, when it's time to light things up, you enjoy the full force of a 3-Watt L.E.D. that uses 51 lumens of light to punch a 150-foot hole in the darkness. Complete with a black sheath and three AA batteries, the TX3.0 projects a professional attitude as well as a commanding beam of light. Use either of the two modes: locked on for constant illumination, or intermittent for signaling. And in situations when accidental light would give away your position, you can lock the TX3.0 in the off position.
