Nitecore NU25 MCT UL 400 Lumen | USB-C Rechargeable

The Nitecore NU25 MCT UL is one of the lightest full-performance headlamps in the ultralight world, weighing just 1.66 oz (47g) including the headband and bracket. Built for backpackers, trail runners, and thru-hikers, it delivers a powerful 400-lumen output in an incredibly compact, barely-there design.

What sets the NU25 MCT UL apart is its Multi-Color Temperature (MCT) lighting system, allowing you to switch between warm (3000K), neutral (4500K), and cool (6500K) white light. This lets you match lighting conditions for fog, rain, technical trail navigation, or long-distance visibility without sacrificing output.

Powered by a built-in 700mAh USB-C rechargeable battery, the NU25 MCT UL delivers up to 45 hours of runtime on ultralow mode and charges quickly from any power bank—perfect for multi-day trips like the JMT, PCT, or weekend alpine missions.

It also includes a red light mode for preserving night vision, a lockout function to prevent accidental activation in your pack, and an IP66-rated body designed to handle rain, dust, and rugged use in the backcountry.

At just 1.66 oz (47g), this is a top-tier choice for anyone trying to cut weight without giving up reliable nighttime performance.
