UT27 2025 headtorch

The Nitecore UT27 headtorch (2025 version) is designed for trail running and hiking, delivering up to 800 lumens at 74 g. Its hybrid design runs on the supplied HLB1500 rechargeable battery or 3 AAA batteries, readily available anywhere: a real advantage on multi-day trips.

Powerful light with accurate colour rendering

Its two MCT LEDs offer three colour temperatures: cool (6500 K), neutral (4500 K) and warm (3000 K). This 2025 version focuses on colour rendering (CRI 97 in warm light), making trail contours, roots and stones easier to distinguish. Warm light also penetrates rain, snow and fog more effectively.

In Turbo mode, the beam reaches up to 168 m, helping you anticipate technical descents. The wide beam (over 100°) also illuminates the edges of the path. A steady or flashing red light completes the features.
