The Nitecore UT27 is a trail running headlamp that delivers 800 lumens and 168 meters of throw in a lightweight 74-gram package specifically designed for the demands of nighttime trail and ultra running. The high-CRI LED with three selectable color temperatures lets runners choose the beam tint that provides the best contrast and depth perception on their specific terrain — cool white for reflective trail markers, neutral for balanced visibility, or warm for reduced eye strain on long night sections. Dual power options give you flexibility to run with the built-in battery for short races or attach an external pack for ultramarathon distances. USB-C charging keeps you topped up at aid stations.
At 74 grams the UT27 stays put on your head during aggressive downhill running and technical scrambles without the bounce and discomfort of heavier headlamps. The three color temperature options are more than a gimmick — experienced trail runners know that warm tones reduce eye fatigue during all-night efforts while cool tones maximize contrast for technical rock gardens and root-laced singletrack. The 168-meter throw illuminates the trail far enough ahead for confident route-finding at speed, and the dual power system means you can scale your battery capacity to match the event distance. Whether you are running a nighttime 50K or navigating a pre-dawn summit bid, the UT27 delivers purpose-built performance that generic headlamps simply cannot match.
