Nitecore NU21 Ultra Lightweight Headlamp

The NU21 is a new addition of NITECORE’s NU Series with extreme simplicity design. Upgraded on the output, light beam, charging port and operation, it weighs only 44g (1.55 oz), providing a lighter and better experience for users.

Utilizing a unibody optical lens system with a light transmission of over 94% and high performance LEDs, the NU21 delivers 360 lumens of blazing white light. It is specially designed for reflecting a uniform and soft light ideal for night running and route finding.

The NU21 uses an ultra lightweight headband, featuring reflective and glow-in-the-dark performance for alerting pedestrians and vehicles, guarding your safety at night. The red light is ideal for map viewing, emergency response, stargazing, and more.

With a built-in 500mAh Li-ion battery, the NU21 is available with USB-C input and cycle charging, which can reduce the discard of 700+ AAA batteries over a battery life cycle. Apart from the Lockout Mode to prevent accidental activation, it is one-hand operable to control the beam and show the remaining battery power. The NU21 is IP66 rated with 1 meter impact resistance, making it more durable in extreme environments.
