Nitecore MH40 PRO 3500 Lumens - Long Throw Flashlight - Wireless Switch

The Nitecore MH40 PRO flashlight offers a maximum output of 3500 lumens with a reach of 1300 meters, ideal for hunting, tactical operations and search and rescue missions. Equipped with the NiteLab UHi 40 MAX LED and a revolutionary wireless remote switch, it combines extreme power and remote control up to 1 meter distance. Versatile and rugged, this 9.52oz flashlight certified IP68 combines performance and practicality for all your professional tactical lighting needs.

NiteLab UHi 40 MAX LED and Wireless Switch

The NiteLab UHi 40 MAX LED system with SMO reflector and 50,000 hours lifespan offers 3500 lumens of power with an exceptional reach of 1300 meters, ideal for illuminating targets at very long distances during night hunting, tactical operations and surveillance missions. The revolutionary wireless remote switch allows you to control the flashlight up to 1 meter distance without cables, greatly facilitating weapon mounting with the 2 included Picatinny mounts. Two power options offer maximum versatility: the included NBP100R 10,000mAh battery delivers 3500 lumens for 45 minutes with 62 hours maximum runtime, while 2 x 21700 batteries offer 2000 lumens for 1 hour with 65 hours runtime. The wireless switch powered by CR1632 battery allows approximately 4000 presses with 12 months standby time, while the intelligent memory function memorizes the last brightness level or Strobe mode used (SOS and Beacon excluded). Rapid charging completes in 3h40 via USB-C port with red indicator (5V/3A charger), and the 5V/3A USB output transforms the NBP100R battery into a powerbank to charge your external devices.

Professional Tactical Construction and Durability

Designed to withstand the most demanding tactical and hunting environments, the MH40 PRO combines aero-grade aluminum alloy with anti-scratch Type III hard-anodized finish in a robust format of 10.08 inches. Night hunting, rescue operations, extended surveillance missions — this flashlight takes everything thanks to its IP68 certification with submersion up to 6 feet and its impact resistance from 3 feet. The ergonomic controls (power switch at the base and mode button) combined with the 2-button wireless remote switch allow you total control adapted to each situation, while ATR technology (Advanced Temperature Regulation) automatically regulates power according to working conditions and ambient environment to maintain optimal performance. With 62 hours maximum runtime in LOW mode with NBP100R battery and only 9.52oz, it becomes that essential tactical companion — always performing, never bulky. The vibration indication every 10 seconds alerts you when remaining power is below 10%, while the 3 charge indication levels (≥50%, <50%, <25%) allow precise runtime tracking.

Operating Instructions

Power switch at base + mode button + wireless remote switch (2 buttons A and B) for complete control

Momentary Tactical Activation: When the light is off, press and hold the switch at the base halfway to turn on momentarily. Release to turn off.

Main LED ON/OFF: ON: When the light is off, briefly press the power switch until you hear a click to turn it on. OFF: When the light is on, briefly press the power switch until you hear a click to turn it off. The MH40 PRO has a memory function. When reactivated, it automatically accesses the previously memorized brightness level or Strobe mode (SOS and Beacon excluded).

Brightness Levels: When the light is on, briefly press the mode button to cycle through LOW - MID - HIGH - TURBO.

Special Modes (Strobe / SOS / Beacon): When the light is on, press and hold the mode button to cycle through STROBE - BEACON - SOS. Release the button to select the desired mode. Briefly press the mode button to return to previous state, or briefly press the power switch to turn off.

Wireless Remote Switch: The MH40 PRO is equipped with a wireless remote switch for wireless control. After pairing (factory preset), the buttons have the same functions as those on the flashlight. Powered by CR1632 3V button battery allowing approximately 4000 presses with 12 months standby time. Maximum signal range: 1 meter without obstacles. To replace the battery: remove the cover using a fingernail or key.

ON/OFF Remote Switch: The MH40 PRO can only be controlled using the remote switch when it is on. ON: When the light is off, press button A fully to turn it on. OFF: When the light is on, press button A fully to turn it off. When the flashlight is off, the power indicator under the mode button flashes every 5 seconds to indicate the remote switch is paired. If no operation is performed within 2 hours, the remote switch automatically disconnects.

Brightness Levels Remote Switch: When the light is on, half-press button A to cycle through LOW - MID - HIGH - TURBO.

Direct Access to Turbo Mode Remote Switch: When the light is on, press and hold button B to access TURBO mode. Release to return to previous state.

Access to Special Modes Remote Switch: When the light is on, half-press and hold button A to access STROBE mode. Then half-press button A to cycle through STROBE - BEACON - SOS. Half-press and hold button A again to exit special mode.

Charging Function: Use the USB-C cable to connect an external power source to the charging port. Charging time: approximately 3h40 (5V/3A adapter). During charging, the red indicator flashes. When the battery is fully charged, the red indicator lights up continuously.

Charging External Devices: Equipped with a USB output, the NBP100R can charge external devices. When the battery is discharging, the green indicator remains on. Output: 5V/3A. If the battery voltage is too low during discharge, the NBP100R automatically turns off the output to extend battery life.

Power Indication: When the light is off, press the power switch while holding the mode button, then quickly release both buttons to access the power indicator. The indicator under the mode button flashes to indicate remaining charge: 3 flashes (≥50%), 2 flashes (<50%), 1 flash (<25%). Once flashing stops, the flashlight turns on.

Low Power Vibration Indication: When the light is on and remaining power is below 10%, the MH40 PRO vibrates every 10 seconds to inform the user.

ATR Regulation (Advanced Temperature Regulation): The integrated ATR technology automatically regulates power according to working conditions and ambient environment to maintain optimal performance.
