Powered by a 10A battery, the Nitecore MH40 Pro Rechargeable LED Flashlight can produce a blazing 3500 lumens and a throw estimated at over half a mile. Along with four brightness levels, the MH40 Pro features a disorienting strobe, an SOS mode, and a location beacon. The on/off switch is located on the tailcap and the mode selector switch is just below the head. The light can also be controlled by a wireless remote switch that comes with hook-and-loop straps as well as Picatinny rail mounts.
