Nitecore NU21 360 Lumen Headlamp White

Ultralight headlamp for night activity

The Nitecore NU21 is a rechargeable headlamp that delivers up to 360 lumens from a primary white LED and weighs only 1.55 oz. It includes dual red LEDs, SOS and beacon modes, plus a reflective headband that glows in the dark. The hollow bracket design keeps the fit secure and nearly weightless during trail running, jogging, backpacking or trekking.

Replaces heavier or disposable-battery lights

This headlamp upgrades from bulkier headlamps or models that rely on replaceable cells by offering USB-C charging that reaches full in 1.5 hours and a maximum runtime of 37 hours. The jump is worth it when you need a low-profile light with emergency signalling and night-vision preserving red output for extended outdoor use.

Check headband fit and charge routine

Verify that the single included headband suits your preferred wearing style and that the reflective glow feature meets your visibility needs. Confirm you can charge via USB-C with the supplied cable and that the IP66 water resistance and 1 meter impact rating match the conditions you expect on the trail.
