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 Nice Headlamp! January 30, 2023
Reviewer: James Frazier from OverlanOd Park, KS United States  
I had to bend a band clamp to get it to fasten - no problem. Great lightweight lamp with intuitive buttons.  I really like a separate button for red light on/off!  USB-C charging is also a plus.

4 of 5 NU-25 January 25, 2023
Reviewer: Mi from Ft Collins, CO United States  
I can't provide an honest review yes since I haven't used it.  I can say it is much lighter than my BD Storm and seems to be easier to scroll through the settings. It will be plenty bright for early morning or night hiking but that time is a few months away.

5 of 5 Convenient! January 3, 2023
Reviewer: Gerry L. from Kihei , HI United States  
I don’t know why I waited so long to purchase this headlamp as I am now able to easily walk my dog at night hands free without holding a flashlight.  However, the big advantage is that this is the newer version. The headband is extremely comfortable and the adjustments to your size are flawless.  Additionally the dual LED lights are sufficiently bright in all three settings with the combined spot and floodlights. The accessibility of the power indicator lights completely removes the guess work as to when you need to recharge the battery.  The USB-C charging capability makes it a definite advantageous as well.

5 of 5 Light and LONG battery 🔋 November 13, 2022
Reviewer: Wes Piatt  
I’m a flashlight junkie, When I found nitecore it was like “these guys get the obsession “ lights, batteries, gadgets, and hilarious videos. This is my 3rd light from them and it exceeded my expectations. Light weight: all my other headlamps use AAA batteries,
The nu25 is half the weight of my Black Diamond equivalent.
Battery life: I was out repairing equipment the other night and I didn’t realize I had both beams on high for over an hour. Convenient battery gauge showed full charge after running it like that. My other headlamps would have been at 2/3 easily.
Comfortable: details in the headband, high quality materials, very easy to adjust.
Beam spread: light choice makes choosing your beam spread easy and it throws plenty of light down. Critical for me is the option for the red light as well.
Con: my only wish would be the ability to dim it further on any setting.
Other than that it is my new go to headlamp, Thx Nitecore
