Triple Output Headlamp

The NU25 is back lighter and more powerful than before with a dual beam spotlight and floodlight for a combined 400-lumen max that can reach out to 70 yards. Equipped with an upgraded unibody optical lens system switch freely between a primary spot LED, offering three brightness settings, to the flood LED for even wide illumination, ideal for close-up tasks and reading. Alternatively, switch to the dual red auxiliary LEDs and protect your night vision or long-lasting signal light. The NU25 is rated IP66 water resistant, features a bold new aerodynamic unibody design that efficiently dissipates heat, and looks stylish to boot.

USB-C Fast Charging

The NU25 has a built-in 650mAh rechargeable battery that can achieve a maximum runtime of 45 hours on its lowest setting. Now with an integrated USB-C port the NU25 fast charges to full in only one and a half hours. A power indicator tells you when it's time to charge while lockout mode prevents accidental activation. The intuitive dual-button interface puts the controls right at your fingertips so you have more time to enjoy the surroundings.


The NU25 is a hybrid band and cord set up newly designed by Nitecore to be even lighter and more comfortable for outdoor users and enthusiasts. The rear plate of the NU25 has two latches that snap down on the headband allowing for easy detachment for cleaning and maintenance. The headband portion is lightweight, elastic, and comfortable with the thick silicone band for enhanced grip.

5 of 5 Not just for your head! November 10, 2022
Reviewer: Patrick Smith from Claremont, CA United States  
I clipped this to my backpack strap, and it did great. I hike with at least 3 light sources. On this first trip out with the NU25, the flashlight switch got finicky, the E-Lite 150 fell off, and I nursed this little guy through 12 hours (2 hours pre-dawn, and 1 hour of sunset walking). Very happy with it.
