Ultralight 360-Lumen Headlamp

The Nitecore NU21 is a rechargeable headlamp that delivers up to 360 lumens of white light and weighs only 1.55 oz. It uses a unibody optical lens to produce a uniform, soft beam reaching 63 yards. A built-in USB-C port recharges the unit fully in 1.5 hours for a maximum runtime of 37 hours.

For Runners and Backpackers

This headlamp suits trail runners, joggers and backpackers who want a lightweight, hands-free light with long endurance and fast charging. The reflective, glow-in-the-dark headband adds visibility at night. Buyers who need replaceable cells or a non-rechargeable power source should consider a different design.

USB-C Rechargeable in 1.5 Hours

The integrated USB-C interface is the single specification that determines whether this headlamp fits your kit. It reaches full charge in 1.5 hours and runs up to 37 hours on a single charge. If your trips require swappable batteries or no USB power access, this model will not meet that need.
