A "soft start" has been implemented as a special feature, which makes the headlight compatible even with systems that react sensitively to high starting currents. This measure also improves the service life and brightness stability of the LED illuminant.

Technology

TERRAFLUXE LINSE
The TERRAFLUX lens is a milestone in optical engineering. No other lens produces such a bright and smooth beam on the road while at the same time illuminating the immediate surroundings above the light-dark boundary. With the TERRAFLUX lens, you are noticed by traffic without dazzling oncoming riders. The clever beam shape of the TERRAFLUX lens throws 90% of the light onto the ground, exactly where you need it. It spreads out as a smooth, wide carpet of light that starts right in front of the wheel and reaches far into the distance. The permanent daytime running light engineered in the lens greatly increases the visibility of the rider in traffic. At night, this same part of the beam illuminates the surroundings exceptionally well and warns the rider of low-hanging branches on the trail. For years now, we have been driving forward the development of the TERRAFLUX to make the lens even more efficient and the light beam produced even brighter. In some of our latest products, the fourth version of the TERRAFLUX is already being installed. This recording breaking generation now has a high beam!
