Dual Beam 800 Lumens Headlamp
The Nitecore UT27 stands out as a bright lightweight headlamp designed for running, with insights from professional trail runners across the globe. It features both white and warm light options. The white light spans an impressive 160 meters and yields an output of 500 lumens, ideal for outdoor pursuits like trail running, hiking, and nocturnal strolls. Conversely, the warm light extends up to 136 meters with the same 500-lumen output making it excellent for penetrating challenging weather conditions like rain, snow, or fog. By combining both lights on Turbo mode, an astounding 800 lumens of brightness emerges, casting a seamlessly uniform beam that reaches 160 meters. The UT27 further offers a red light mode, switchable between a steady glow and a flashing signal, facilitating awareness of your surroundings. Effortless toggling between light options and brightness adjustments is enabled through the user-friendly dual switches.
Multiple Ways to Power
Accommodating various power options, the UT27 comes with HLB1300 USB-C rechargeable battery pack while is compatible with 3x AAA batteries. A power indicator signals when it is time to recharge, and the lockout mode prevents accidental activations. Its ultra-low standby power consumption ensures a ready state throughout the year. For those navigating the night, a glow-in-the-dark battery compartment simplifies battery replacement.
