Lightweight headlamp for outdoor use

The Nitecore NU31 is a rechargeable headlamp weighing 3.3 oz and delivering a maximum output of 550 lumen with a beam distance of 158 yards. It is designed for night running, camping and general outdoor activities where low weight and hands-free illumination are priorities.

Upgrade from disposable-battery lights

This model replaces headlamps that rely on replaceable cells by integrating a USB-C rechargeable battery. The jump is worth it when you want fast 1.5 hour charging, runtimes up to 147 hours on the lowest setting and the convenience of topping up from any USB power source.

Check headband fit and charging access

Before ordering, verify that the included headband suits your head size and helmet compatibility needs. Ensure you have a USB-C cable and power source available for recharging, and confirm that IP66 water resistance meets the exposure level of your intended use.

Questions about this item

What headband is included for mounting the NU31?

The package includes a headband designed for the 3.3 oz unibody so the light sits securely on your head during night running or camping.

How do I charge the built-in battery and what mistake should I avoid?

Plug the supplied USB-C cable into the integrated port; a full charge takes 1.5 hours, but remember to disengage the lockout mode first or the headlamp will not accept a charge.

When will the rechargeable battery need replacement and how do I know?

The power indicator shows remaining capacity; when runtimes drop well below the rated 147 hours on extra-low or 5 hours on high, the internal cell is nearing end of life.
