Overview
Nitecore built this headlamp around a unibody polycarbonate and aluminum shell with three separate LEDs: a main white beam, a high CRI auxiliary light and a red light. It charges over USB-C and straps on with the included headband.
Three light types on one band cover reading, night vision and long throw without swapping lamps. Fast USB-C charging suits phone power banks. Weight is not stated, and the sealed battery means no quick swap of cells on the trail.
Who it's for
Campers, hikers and night runners who already carry a USB power bank. Those who prefer swapping disposable batteries in remote country should choose a lamp that takes AAA cells.
Pros and cons
- Separate red and high CRI LEDs
- Long beam reach on high
- SOS and beacon modes
- Quick USB-C recharge
- Battery cannot be swapped in the field
- Weight not listed
- Top output runtime not stated
Performance notes
Runtime falls as output rises, so the long figure applies to the lowest setting rather than full brightness. The unibody shell pulls heat away from the main LED, which helps it hold higher output. The high CRI light shows true colors for map reading and first aid.
