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.
The long handle houses a 10,000mAh Nitecore NBP100R battery that recharges via USB-C, but the MH40 Pro can also run on two 21700 batteries with modestly lower output. A Nitecore UHi 40 Max LED and Precision Digital Optics Technology reflector account for the long beam distance. Waterproof and impact resistant, the light is equipped with a battery level indicator LED in the mode switch and will vibrate if remaining battery power drops below 10 percent.
