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.

Questions about this item

How much head clearance does the 1.55 oz NU21 headlamp need?

The unibody optical lens and hollow bracket sit close to the forehead, so only a few millimetres of clearance above the band are required; the 1.55 oz weight adds no noticeable bulk.

What is the common mistake when charging the integrated USB-C port?

Users often plug the cable in before the port cover is fully flipped open, which can bend the cover hinge; always open the cover completely first.

When should the headband be replaced on the IP66-rated NU21?

Replace the reflective, glow-in-the-dark headband when the elastic no longer holds the lamp securely or the reflective strip stops glowing after dark exposure.
