The Nitecore NU50 headlamp has a maximum output of 1400 lumens from the high performance LED and is powered by a built-in 21700 li-ion battery, which is rechargeable via a USB-C port on the side of the light.

The NU50 has five white brightness levels, SOS and beacon outputs and a red mode. With both a constant-on and flashing red setting, the headlamp is ideal for map reading, emergency use, night photography and more.

The light is operated by a dual switch user interface; a power button to turn the light on and off, plus a mode button to switching between the outputs. The headlamp has a built-in sensor protection function which automatically lowers the brightness level when an obstruction is detected.

Designed with a combined structure, the NU50 is lightweight, rigid and durable making it suitable for complex environments. The overall weight of 146g includes the bracket, battery and headband and is equivalent to a conventional 18650 metal headlamp on the market.

The headband features a hollow design for lightweight and comfort and the reflective strips alert pedestrians and vehicles when out at night.

Brightness Levels:
White light
Turbo: 1400 lumens
High: 600 lumens - 13 hrs runtime
Mid: 300 lumens - 20 hrs runtime
Low: 100 lumens - 38 hrs runtime
Ultralow: 8 lumens - 200 hrs runtime

Red light
Constant-on: 5 lumens - 120 hrs runtime
Flashing: 10 lumens - 120 hrs runtime

Plus SOS and Beacon modes (1400 lumens).

Advanced temperature regulation (ATR) regulates the output of the NU50 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 130 meters, waterproof to IP68 and resistant to impacts up to 2 meters.

Includes: headband, USB-C charging cable.
