Hand flashlight Nitecore MH40 PRO — LED 3500 lm, USB rechargeable, 10000 mAh, IP68 waterproof, black

The Nitecore MH40 PRO is a handheld LED flashlight delivering up to 3,500 lumens from a single UHi 40 MAX LED and a maximum beam throw of 1,300 metres. Designed for demanding outdoor, tactical and work environments, this compact metal-bodied torch integrates a built-in 10,000 mAh rechargeable battery (NBP100R) with USB‑C charging and also accepts two 21700 cells. The body weighs approximately 270 g, with a head diameter of 6.5 cm and a length of 256 mm. The MH40 PRO features precision optics, durable aero-grade aluminium construction with HA III hard-anodized finish, and an IP68 rating for submersion to 2 m.

Advantages

The MH40 PRO combines high light output and long-range performance with flexible power options: use the included rechargeable Li‑ion battery or two 21700 cells. Its precision Digital Optics Technology (PDOT) and double-sided coated lenses focus a powerful, stable beam while the Advanced Temperature Regulation (ATR) maintains consistent performance under load. Practical details such as a power indicator, low-power vibration alert, wireless remote switch and a tactical tail switch make operation intuitive in field conditions. The flashlight is impact resistant to 1 m and rated IP68 for water and dust protection.

Suitable for

• Search and rescue operations and long-range signalling
• Tactical use and law enforcement tasks
• Professional outdoor work and inspection jobs
• Camping, hiking and night navigation
• Emergency preparedness and roadside assistance

How to use

Charge the included NBP100R battery via the built-in USB‑C port until the power indicator shows full. Install either the internal rechargeable pack or two 21700 cells according to polarity marks. Turn the flashlight on or off using the tactical tail switch; change brightness levels and special modes with the mode button. Use the wireless remote switch for hands-free or weapon-mounted activation where applicable. Monitor the power indicator and low-power vibration alert to plan recharging or battery replacement.

Usage recommendations

For longest service life and reliable performance, use the supplied NBP100R rechargeable pack for routine use and ensure the charging port is dry before connecting a cable. Avoid prolonged continuous use at maximum output to reduce thermal stress; the ATR system will regulate temperature but intermittent operation extends runtime and component life. Rinse and dry the exterior after saltwater exposure and store the torch in a cool, dry place when not in use.
