Description
Bright Headlamp for Running and Outdoor
Refined from the popular UT27, the Nitecore UT27 MCT introduces multiple color temperatures and upgraded features, delivering a bright yet lightweight headlamp designed for running and outdoor adventures in any condition. Developed with insights from professional trail runners, it outputs a powerful 800 lumens with a beam reaching 183 yards, making it ideal for trail running, hiking, camping, and night walks.
3 Color Temperatures and Red Lights
The UT27 MCT offers three selectable color temperatures: 3000K warm light for better visibility in rain, fog, and snow; 4500K neutral white for clarity on steep slopes, streams, and muddy terrain; and 6500K cool white for maximum brightness and contrast during camping or urban night running. It also includes a red light mode, with steady or flashing options, to preserve night vision and enhance situational awareness. Dual switches allow fast, intuitive control for cycling between modes and adjusting brightness on the go.
Flexible Power and Rugged Design
For power, the UT27 MCT includes a USB-C rechargeable HLB1500 battery pack and is also compatible with 3×AAA batteries for backup flexibility. A built-in power indicator shows charging status, while lockout mode prevents accidental activation. With ultra-low standby power, it stays ready year-round, and a glow-in-the-dark battery compartment makes replacements easy in the dark. Weighing just 2.61 ounces (with battery and headband), the UT27 MCT is an excellent running companion. The breathable headband features a silicone strip that keeps the lamp secure and channels sweat away from the eyes, while reflective decals boost nighttime visibility. Rugged and reliable, the UT27 MCT withstands 1-meter drops and carries an IP66 rating, protecting against heavy rain and splashes.
