The Supernova M99 DY PRO is the first dynamo LED headlight with high beam functionality from Supernova. Thanks to its innovative control electronics, the headlight achieves light output of over 1000 lumens and 200 lux with its matrix of 11 power LEDs. Once installed, the headlight is completely maintenance-free and illuminates the path ahead for years with an illumination strength optimally adjusted to your speed. During the day, the light sensor switches to a special 1W energy-saving mode, ensuring you remain well visible while riding during daylight. The LEDs for high beam and low beam are automatically mixed from the LED matrix, providing perfect safety lighting during the day. When passing through a tunnel, the headlight automatically switches to the bright, wide low beam with over 600 lumens of light output in a fraction of a second.
