Busch und Muller IQ-X 100 lux hub dynamo headlight

Busch und Muller's IQ-X headlight is designed especialy for hub dynamos. With a 100 lux output this is the brightest dynamo headlight ever to be made. Some light is purposefully emitted to the side to enhance visibility, but the majority is directed in a shaped beam so that it lights the road for you to see where you are going without wasting light upwards by blinding oncoming cyclists.

The body of this light is made of CNC Alloy. One switch on the rear toggles off / senso. In senso mode, the light automatically switched to daylight mode in the day and automatically switches to a standlight mode when you stop cycling (i.e. it remains lit for a period of time).

Can be used with a dynamo rear light, a battery rear light or on its own. Comes with an optional reflector. See additional photos.

Warning: This light works only with a hub dynamo (AC)
