Busch + Müller Lumotec IQ-X E Type LED Front Light E-Bike

The Busch + Müller Lumotec IQ-X uses a high-tech illumination and is one of the first dynamo powered lights with 150 Lux. It has got an extensive light field and a great close range illumination. The eye-catching casing is made of aluminum. A lateral light emission increases the side-visibility. The power switch is bordered by a blue glowing ring. Furthermore the IQ-X features a sensor controlled daytime running light, a stand light function, a screw-on reflector and a flexible bracket with integrated cable channel which can also be mounted overhead. With German mark of law approval.

On e-bikes, the light system is powered by the vehicle’s battery. Therefore, e-bikes require special headlights and rear lights – this goes for both pedelecs and speed e-bikes. Until 2013, it was not permitted to power the light from the battery, that is why older e-bikes have a dynamo and a regular bicycle headlight.

HE DECIDING FACTOR There is one major technical difference: dynamos supply 6 V AC power, but e-bike batterys supply DC voltage – depending on build and drive system 6 to 42 V or even higher. Our headlights are compatible with almost every system they flexibly operate with a multitude of different voltages. A separate, capacitor-powered standlight function is not required, because the e-bike battery constantly supplies power so that standlight is always ensured.
