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 Quality and Lightweight May 11, 2024
Reviewer: Cody Breeden from Atoka, OK United States  
I got this headlamp for around the campsite. So far it has been excellent. I like the unique strap that it has, it holds good and hasn’t loosened on me yet. The only issue I have had with the light is the ui. Several times I have locked out the light trying to get to the instant red light. I feel like that more on me and not the light. All in all I would say it one of the top out there in the $30-$40 price range.

1 of 5 Removed low red setting… December 9, 2023
Reviewer: Anonymous Person from Maryland  
Another “upgrade” that is a downgrade because the product developers are ignorant of how to use their own products properly.  The original NU25 360 had a low red setting (0.9 lumen) that was still a bit too bright for preserving dark adapted vision, but it was workable.  Now the new version eliminates that leaving only a blazing 10 lumen red option.  Total non starter.  Red light is not magic, it must still be very low lumen to have a hope of maintaining dark adaptation.  Thanks Nitecore for utterly ruining what was formerly a useful product!

5 of 5 Light and Bright October 29, 2023
Reviewer: Steven Gustafson from Port Orchard, WA United States  
Very light weight. Have had it out for a two-night trip in the rain and it performed perfectly. Plenty of charge left after two nights. I won't be going back to non-rechargable  headlamps.  In spite of the directions, it takes a while to figure out all the button combinations that produce different lighting options. That's just a matter of practice.  If it holds up, I'll definitely buy one again.
