Lupine SL SF E-Bike Headlight Bosch

"F" stands for high beam - the SL F for e-bikes
The sensor-controlled "daytime running light" and glare-free 1000 lumen dipped beam light bring you safely through road traffic at any time of day. At the touch of a button, you unleash the 1300 lumen high beam and fire your bike over challenging trails.
  
The dipped beam of the SL F is designed after the model of a car headlight and absolutely glare-free for oncoming road users. The 1300 lumen high beam of the SL F is not just a stronger dipped beam. At the touch of a button, the entire light image changes and illuminates an additional area far above the glare-free cut-off line: perfect for fast journeys and demanding trails. In contrast to other StVZO-approved bicycle lighting systems, the SL F's light image is not limited to a small strip but conjures up a wide and homogeneous carpet of light directly in front of your front wheel.

At the heart of the Lupine SL are 18 Osram Compact CL Automotive LEDs and the world's first Dual Aspheric Lens System for bicycle lamps. The material used for the lenses is extremely weather-resistant and is also used, for example, in aviation and medical technology. The extremely robust and high-quality aluminium body reliably protects the SL AF from shocks, dust and water.
