IQ Technology
The revolutionary light from Busch & Müller: a special reflector with an optimised cooling system uses a high-performance LED as an indirect light source. The LED is not visible any longer in the middle of the reflector. This creates a light field that is extremely evenly illuminated and can be twice as wide as conventional technology. Light effects can be positioned more precisely - for example, the near field in front of the front wheel can be additionally brightened.

Standing Light
This innovation by busch+müller from the nineties has become the safety standard. The additional " plus" indicates that standing lights are integrated into the equipment. Neither batteries nor rechargeable batteries are required for the standing light. This is how it works: As soon as the bike is stationary, an LED standing light is supplied with power by a maintenance-free capacitor. The capacitor charged itself during the journey.

By the way: The standing light of the Lumotec headlights can run for many minutes. This is why the standing lights on Lumotec IQ models can also be switched off manually - so that no thief is tempted when the bicycle is parked.

Landstraßen nachts im Wald verlieren viel Schrecken mit diesem Scheinwerfer.
Die früher bemängelte Undichtigkeit konnte ich bislang nicht feststellen trotz heftigen Regens in letzter Zeit.

Das Licht ist sehr gut im Vergleich mit allen anderen (STVZO) Lampen die ich bisher gefahren habe.
Allerdings bin ich von der Wetterfestigkeit nicht so überzeugt. Nach einer 2 1/2 Stündigen Regenfahrt hatte ich Wasser im Scheinwerfer (von Innen an der Scheibe).
Dabei kam das Wasser "nur" von oben, weil von unten ein Schutzblech drunter war.
Bei einem Produkt in dieser Preislage hätte ich mehr Erwartet.

Es werde Licht!!!
Gigantisch, wie viel Licht sich aus 3W herausholen läßt. Ohne STVO würde der Radler mehr sehen.
