Overview
A built-in USB-C port charges the Nitecore NU27, a headlamp with warm, neutral and cool white LEDs and a separate auxiliary red light. The body is made from durable PC material and ships with a headband and a clip.
Three color temperatures let you match the light to the task, from a gentle warm tone to a cool tone for visibility outdoors. The limitation is size information: the listing gives no weight and no dimensions, so head comfort is not documented.
Who it's for
Hikers, runners and campers who like choosing a color temperature and charging over USB-C will find the specs lined up. People with strict weight limits, or those who need to swap cells in the field, should look at other lights.
Pros and cons
- Three white color temperatures
- Auxiliary red light
- Diffusing stuff sack included
- Weight not listed
- Dimensions not given
- Battery must be recharged, not swapped
- PC body, not metal
Performance notes
Maximum output and beam distance drop as you step down the output modes, and runtime rises. Warm white is described as easy on the eyes in fog and rain, while cool white lifts visibility outdoors. The red light has its own outputs for tasks where night vision matters.
