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.
