The NU25 MCT is equipped with the MCT UHE LEDs featuring three color temperatures and high luminous efficiency and a built-in battery with higher capacity. The three color temperatures in both primary lights include the 3,000K warm light with excellent penetrating ability in fog, rain and snow, 4,500K neutral white light suitable for various outdoor activities, and the striking and refreshing 6,500K cool white light. The NU25 MCT is undoubtedly the latest iteration with the longest runtime ever.
