Nitecore UT27 MB 800 Lumen Trail Running Headlamp with Red Running Light

Available In-Store Only.

Built for moving fast after dark, the Nitecore UT27 MB is a lightweight, high-performance headlamp designed for trail running, hiking, backpacking, camping, and other nighttime adventures. With up to 800 lumens, a beam distance of 183 yards, and a weight of just 2.61 oz, it delivers serious illumination without weighing you down.

The UT27 MB uses Multiple Color Temperature (MCT) LEDs so you can choose the right light for the conditions. Switch between 3000K warm light for better visibility through fog, rain, and snow, 4500K neutral white for balanced everyday illumination, or 6500K cool white for maximum brightness and long-range visibility. The result is a versatile headlamp that works just as well on a predawn trail run as it does around camp after a long day in the mountains.

Powerful Red Light for Nighttime Use

The UT27 MB's three-level red light is far more powerful than the basic red LEDs found on many headlamps. The high setting produces 150 lumens with up to 76 yards of throw, making it useful for spotting trail markers, navigating camp, locating gear, or emergency signaling. Drop to the mid or low setting when you want comfortable close-range illumination while preserving your night vision for reading maps, preparing gear, or moving around camp.

Lightweight, Flexible & Trail-Ready

At only 2.61 oz, the UT27 MB is easy to wear for hours during long trail runs, overnight backpacking trips, or extended hikes. The 90° adjustable bracket lets you direct the beam where you need it, while dedicated white and warm-light controls and instant-access red light make changing modes quick and intuitive.

Power the headlamp with the included Nitecore HLB1500 rechargeable battery pack, or switch to 3 AAA batteries when you need a readily available backup power source. An integrated battery level indicator helps you keep track of remaining power, while the IP66 water resistance and 1-meter impact resistance make the UT27 MB ready for rough weather and everyday trail abuse.
