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.
