The HA23 UHE utilizes MCT Self-Developed Lighting System with Multiple Color Temperatures in All Primary Lights. Each primary light is available in 3000K warm light (offering excellent penetrating ability in fog and rain while avoiding glare and reflection in snow), 4500K neutral white light (suitable for various outdoor activities), and 6500K cool white light (providing a striking and refreshing beam during long hikes or runs). Additionally, all primary lights, regardless of color temperature, deliver a max output of 600 lumens and a max throw of 132 meters.
