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 UL is the lightest headlamp, at only 1.59 ounces, optimized for the most dedicated outdoor enthusiast that takes carrying weight very seriously. The dual-band design evenly distributes the weight with a very simple cinching mechanism to control the tightness for user comfort. The multithreaded cord has highly reflective bands for enhanced visibility, as well as glow-in-the-dark bands for visibility without ambient light.

5 of 5 Love this Headlamp March 11, 2024
Reviewer: SG from Dahlonega, GA United States  
We have been searching for a comfortable headlamp to use around the house, primarily for reading and not tripping over the cat at night in those areas that don't have lights. After doing some research, we decided on the NU25 UL. It's exactly what we wanted! From ordering to receiving, the process was fast and easy. And the headlamp itself is lightweight and comfortable. We both hightly recommend it!

5 of 5 Lightweight, minimalist, and comfortable February 21, 2024
Reviewer: AReynolds from Gardiner, NY United States  
Even though the padding on this headlamp is minimal, it is surprisingly comfortable. Its light weight helps a lot. I can use this as my primary headlamp or keep it in my pack as an emergency backup. It's easy to use and seems to maintain a decent charge when kept on its lowest setting.

4 of 5 NU25 UL 400 February 17, 2024
Reviewer: Shawn Nichols from Greenwood, IN United States  
This headlamp is extremely light and has a great range of lighting options.  The reason I only given it 4 stars is i haven't had the opportunity to put it into real world use. I plan to give it a thorough test next month. I will update my review afte that.
Very satisfied so far,  stay tuned.

5 of 5 Excellent Light February 13, 2024
Reviewer: William Brandon from Hoover, AL United States  
I love how easy the light is to use. It is so intuitive !  Plus it is the lightest headlight I've ever used.  Hardly know you're wearing it.  The 400 Lumne is plenty bright for hiking and backpacking.
