Product Details

Busch & Mueller Lumotec IQ-X dynamo headlight

Busch & Mueller have outdone their top-of-the-line Luxos headlights with the 100 lux IQ-X. This is the most powerful dynamo headlight we know of.

The IQ-X's new optical system produces a smoother distribution of light on the road than any other headlight. You can set the light to the power that you want, ranging from 10 to 100 lux in 10-lux increments. How does 100 lux translate into lumens? From a cyclist's perspective, there is no translation. Lumens describes the amount of light produced, whereas lux describes the amount or intensity of light thrown upon a given area at a given distance. From a cyclist's perspective, lux is a much more meaningful indicator of a light's usefulness.

The housing is anodized aluminum and acts as the heat sink for the LED.

The IQ-X has a standing light (like all the B&M lights we carry), as well as daytime running lights. A senso automatically switches to either daytime or nighttime mode. It does not have a blinking mode, and that's good, because a blinking light this powerful would be extremely annoying, not to mention dangerous, to oncoming traffic. Mounting: compatible with other Busch & Müller headlight mounts. The included mount will work on most bikes. As with other B&M headlights, it includes wiring for a tail light.

The sleek appearance of the IQ-X is also a big step forward for Busch & Mueller.

We hope B&M will offer a USB port version of the IQ-X that, like the Luxos U, lets you charge phones, cameras, and other devices while you pedal.
