Supernova E3 E-Bike Headlight V521S


We are constantly improving and this headlamp is a good example. The model is based on the popular V6s housing, which was equipped with a completely newly developed electronics, which can now handle voltages up to 21 volts. As a special feature, a "soft start" has been implemented, which makes the headlight compatible with systems that are sensitive to high starting currents. This measure also improves the service life and brightness stability of the LED light source.
