The NITECORE NU31 rechargeable headlamp is the perfect companion for any outdoor activity, whether it's a casual adventure or a thrilling escapade. Its unibody optical lens system ensures optimal performance by emitting a bright 550 lumen beam that can reach distances of up to 158 yards on Turbo mode. The NU31 offers versatility with its primary white LED that provides three brightness settings, as well as an emergency SOS and beacon. The high CRI auxiliary LED delivers smooth flood illumination, making it ideal for close-up tasks and reading. Alternatively, switch to the red auxiliary LED to protect your night vision or for a long-lasting signal light.
USB-C Fast Charging
The NU31, weighing at only 3.3 oz, is the perfect lightweight headlamp for night running, outdoor adventures, or camping. With a built-in high-capacity rechargeable battery, it can achieve a maximum runtime of 147 hours on its lowest setting. It also has an integrated USB-C port for fast charging, taking only 1.5 hours to reach full power. A power indicator lets you know when it's time to recharge, and lockout mode prevents accidental activation.
Durable and Stylish for Outdoor
The NU31 is rated IP66 water-resistant and features a bold new aerodynamic unibody design that efficiently dissipates heat. The aero-grade aluminum housing offers impact resistance and comes in 3 vibrant colors: slate gray, chill blue, or tangelo orange, adding a splash of style to your gear.
