Triple LED Headlamp
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.

A power indicator lets you know when it's time to recharge, and lockout mode prevents accidental activation.
