The Nitecore NU21 in white is a lightweight rechargeable headlamp for walking, running and keeping your hands free around camp. At 44 g including its bracket and headband, it is easy to add to a small kit. The white beam delivers up to 360 lumens with a maximum beam distance of 58 m.

A built-in 500mAh Li-ion battery recharges through USB-C, avoiding loose batteries for everyday use. High output steps down during extended operation, so select a lower brightness for longer outings. Nitecore publishes eight hours at the 60-lumen setting; actual runtime depends on conditions.

  • Full charging takes about 1.5 hours with a 5V/0.5A supply; the battery is not user-swappable.
  • Direct red-light access from off, plus steady and slow-flashing red modes.
  • IP66 protection covers dust and powerful water jets, not immersion. Keep the headlamp out of water.

Frequently asked questions

Can I replace the NU21 battery on the trail?

No user-swappable battery is provided: the NU21 has a built-in 500mAh cell. Recharge it through USB-C; a full charge takes about 1.5 hours with 5V/0.5A.

How much does it weigh with the headband?

The NU21 weighs 44 g including its bracket and headband. That figure is for the complete rechargeable lamp, not an empty battery housing.

How long will it run between charges?

Published runtimes include 3.5 hours at 170 lumens, eight hours at 60 lumens and 37 hours at 6 lumens. The 360-lumen High setting steps down during extended use, and conditions affect runtime.

Can I access red light without turning on white light first?

Yes. With the lamp off, hold MODE for one second to start red light. It has a steady red setting and a slow-flashing option.

Can the NU21 be submerged?

No: its IP66 rating covers dust and powerful water jets, not immersion. It is for weather exposure rather than underwater use.

Are all products authentic and genuine?

Yes—all items are factory-original units sourced through trusted channels. We never sell replicas or knockoffs.

How do I verify a product’s authenticity?

Genuine items include authenticity markers—scratch-off codes, serial numbers, official packaging. Verify codes on the manufacturer’s site. We only list authentic gear.

Do your products come with warranty coverage?

As these products are shipped globally and sourced through various channels, manufacturer warranties may vary by region. However, we stand behind everything we sell—if an item arrives defective or develops an issue shortly after delivery, we’ll work with you to resolve it quickly and fairly. Our goal is to ensure you receive fully functional, authentic products—no compromises.

How long does shipping take?

Estimated total delivery time, including order processing, is generally 10–17 working days, depending on the product, supplier, shipping method and destination.
