The Nitecore NU25 MCT UL is a lightweight, rechargeable headlamp built for camping, hiking, trail running, and everyday outdoor use. Its ultra-high efficiency LEDs deliver up to 400 lumens with a beam distance of 144 yards. Multiple Color Temperature (MCT) LEDs let you switch between warm (3000K) for fog and rain, neutral (4500K) for natural everyday lighting, and cool (6500K) for maximum outdoor visibility. Choose from four brightness levels in any color temperature, or switch to red light mode to preserve night vision, with low, high, and slow-flashing options. SOS and Beacon modes provide added safety in emergency situations.
