The Nitecore MH40 Pro flashlight has a maximum output of 3500 lumens from the NiteLab UHi 40 max LED and is powered by a dedicated Nitecore NBP100R 10,000mAh li-ion battery pack with a built-in USB-C charging port. Alternatively, the torch can use 2 x 21700 batteries with a discharge current over 8A, such as the Nitecore NL2153HP (sold separately).

The torch is operated by a dual switch interface, made up of a tail switch to turn the light on and off, either fully or in the momentary-on state, and a side switch to cycle through the brightness levels.

A wireless remote switch is included for wireless control and quick response. Featuring 2 buttons, button A turns the light on and accesses strobe and button B is for momentary-on. In addition to the intuitive switch, the MH40 Pro also comes with a hook-and-loop fastener and hook-and-loop straps to attach the remote switch to a convenient place, plus picatinny rail mounts for tactical use.

The flashlight features a randomly changing strobe mode for emergency use, an intelligent memory function, a low power vibration indicator to alert you when the remaining power is below 10% and an intuitive power indication beneath the mode button:

• Flashing 3 times = ≥50%
• Flashing 2 times = <50%
• Flashing 1 time = <25%

With a rugged, durable design, the MH40 Pro is constructed from aero grade aluminium alloy. It has 5 cooling fins for effectively reducing overheating and a slide-proof texture for comfortable grip.

Brightness Levels:
Using Nitecore NBP100R li-ion battery pack:
Turbo: 3500 lumens – 45 mins runtime*
High: 1300 lumens – 4 hrs 15 mins runtime
Mid: 400 lumens – 13 hrs runtime
Low: 80 lumens – 62 hrs runtime
Plus strobe, beacon and SOS - 3500 lumens

Using 2 x 21700 li-ion batteries:
Turbo: 2000 lumens – 1 hr runtime*
High: 1200 lumens – 4 hrs 15 mins runtime
Mid: 400 lumens – 15 hrs runtime
Low: 80 lumens – 65 hrs runtime
Plus strobe, beacon and SOS – 2000 lumens

*Turbo runtime is tested without the temperature regulation.

Advanced temperature regulation (ATR) regulates the output of the MH40 Pro according to the working and ambient temperature to maintain optimal performance while preventing the LED from overheating. The outputs are measured in total of runtime, including output at reduced levels due to temperature or protection mechanisms in the design, causing the brightness level to drop down.

Maximum beam distance 1300 meters, waterproof to IP68 and resistance to impacts up to 1 meter.

Includes: Nitecore NBP100R li-ion battery pack, wireless remote switch, hook-and-loop fastener, 2 x hook-and-loop strap, 2 x picatinny rail mount, USB-C charging cable, spare o-ring, holster, lanyard.
