NITECORE NU31 Full-Metal Rechargeable Headlamp

The NITECORE NU31 is a versatile rechargeable headlamp that combines high output, a durable metal construction, and multiple light sources in a compact design. Delivering up to 550 lumens with a maximum beam distance of 145 meters, the NU31 is designed for a wide range of applications including night running, hiking, camping, trekking, and emergency lighting.

The NU31 features three light sources: a white main light, a white auxiliary light, and a red auxiliary light. The main light delivers up to 550 lumens with a beam spread of over 100°, providing a balance of wide-area illumination and long-distance visibility. The CRI 90 white auxiliary light offers more natural color rendering, making it suitable for reading, checking maps, organizing gear, and other close-range tasks. It also features a gentle 6-lumen Moonlight Mode for low-level illumination in tents or other situations where minimal light is preferred. The red auxiliary light provides both constant-on and slow-flashing modes for nighttime use and emergency signaling.

The front of the NU31 is constructed with an integrated aluminum housing, providing improved heat dissipation and durability compared with conventional plastic designs. The metal construction helps reduce heat buildup during extended high-output operation while offering enhanced resistance to wear and impacts. Despite its durable construction and built-in 1,800mAh battery, the NU31 weighs only approximately 95.5g, making it easy to carry and comfortable for extended use.

A built-in 1,800mAh polymer lithium battery provides reliable power and supports direct USB-C charging, allowing convenient recharging from a power bank or other compatible power source. Ultra-low-power standby technology enables up to 365 days of standby time, making the NU31 a practical choice for both everyday use and emergency backup.

The differentiated dual-button design allows intuitive one-handed operation for switching between light sources and brightness levels. An electronic lockout function prevents accidental activation while the headlamp is stored or carried in a backpack. Four LED battery indicators provide a quick and clear view of the remaining power.

With an IP66 rating for dust and water resistance and 1-meter impact resistance, the NU31 is built to handle demanding outdoor environments. The included full-reflective headband also enhances visibility during nighttime activities.

Combining high output, versatile lighting options, durable construction, and a lightweight 95.5g design, the NITECORE NU31 is a reliable all-around headlamp for runners, hikers, campers, and outdoor enthusiasts.
