The TMT A2 flashlight features a Momentary-On switch, with High-Beam, Low-Beam, and Strobe options on the same tailcap switch! Made from aircraft-grade aluminum, with advanced regulated circuits for maximum output, this light uses two AA batteries (included). With just this pair of AA batteries, though, the light puts out 220 lumens on high beam and strobe modes, and a low-beam output of 15 lumens. You can still read a map on low-beam, and the light will last up to 75 hours on low! This light has a spring-metal pocket clip, anti-roll ring, breakaway lanyard, and this light is tested to ANSI FL1 standard. This light clips on to the Belt Clip/Holster model 53144.
