Nitecore UT6 1600 Lumens - Trail Running Headlamp MCT 3 Color Temperatures

The Nitecore UT6 is a high-performance trail running headlamp, designed for demanding runners facing technical terrain, fast descents and overnight races. It delivers up to 1600 lumens for a 213yd / 195m beam distance, with an ultra-lightweight magnesium alloy construction weighing only 4.59oz / 130g. Its unique MCT (Multiple Color Temperatures) technology allows you to instantly switch between three color temperatures to adapt to every race condition. The UT6 is the essential ultra-distance headlamp to push your limits with full confidence.

MCT Technology and Ultra-Distance Endurance

The MCT technology offers three dedicated color temperatures: warm 3000K (CRI98), neutral white 4500K (CRI85), cool white 6500K (CRI73), each accessible via three direct buttons without menu navigation. Unlike traditional multi-color headlamps, the UT6 maintains full output and throw across all three color temperatures, with zero compromise. Its rechargeable NL1840R 4000mAh battery delivers up to 31h of runtime and recharges via USB-C, with quick battery swap available for extended races. Two dedicated modes: Long-Runtime Mode stretches every charge for prolonged useful illumination, High-Performance Mode maintains a higher average brightness for technical terrain and demanding conditions.

Lightweight Build and Race-Ready Reliability

Beyond its power, the UT6 stands out for its ultra-lightweight design: magnesium alloy and polycarbonate ensure ruggedness without compromising weight. Its unibody optical system with TrueVision+ technology delivers a wide-angle floodlight with smooth, even beam transitions. The Rapid Reel™ headband allows fast one-handed adjustments for a secure fit on the move. IP68 certification guarantees 2m submersion, 2m impact resistance ensures reliability from start line to finish line. At 3.15" × 1.69" × 1.50" / 80mm × 43mm × 38mm for 130g (bracket included), the UT6 is designed for the most demanding 100-mile ultra races.
