The TMT L1 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 one lithium battery (included). With just the single battery, though, the light puts out 212 lumens on high beam and strobe modes, and a low-beam output of only 14 lumens. You can still read a map on low-beam, and the light will last up to 24 hours on low! The tail cap features a momentary-on mode, it has a spring-metal pocket clip, anti-roll ring, breakaway lanyard, and this light is tested to ANSI FL1 standard. This light is compatible with the item 53144 Belt Clip/Holster as well.
