The IQ-X from Busch & Müller. Its newly developed lighting technology makes it possible for the first time to crack the 100-Lux mark with a dynamo headlamp - and that with very wide, wide and homogeneous large-area illumination of the road. The housing, which also serves as a cooling system, is made of high-quality aluminium. The slots in the holder ring, which radiate brightly to the side, set visibility accents, while the ergonomic push-button is embedded in a ring that glows blue. Brightness: 100 Lux.
