This is the brightest dynamo powered bicycle headlight at 100 lux. The new optical system produces a smoother distribution of light on the road than any other headlight. The housing is anodized aluminum and acts as the heat sink for the LED.
Available in either silver anodized or black anodized finish. The IQ-X has a standlight, as well as daytime running lights. Automatic switching between daytime and nighttime modes. The Senso/Off pushbutton switch is at the back of the IQ-X, surrounded by a glowing blue ring. The IQ-X always provides the ideal headlight beam; straight ahead in daylight so that oncoming car drivers are alerted to your presence, changing over at dusk to a beam optimized for illuminating the road surface ahead, but still providing high visibility to oncoming drivers.
The IQ-X ships with its own highly adjustable mount, and is compatible with other Busch & Müller headlight mounts. For most applications the included mount will work. For bikes with limited clearance under the bottom headset cup or with cantilever brakes, use either the CYO or Thorn mount listed below.
The IQ-X is reversible and can be used in "upright" or "upside-down"(i.e. hanging from the mounting point, as it might be on a front rack) orientation.
