New for 2013, the Luxos headlights have a new optical system, IQ2, which provides an even wider beam than the IQ system, and it's brighter too, at 70 or 90 lux. Luxos lights also have B+M's "Licht 24" system of daytime running lights.
The Luxos U is the "deluxe" version. It has innovative new technology that senses rider speed and adjusts light output accordingly, always providing an optimal beam pattern for a given speed. No other light available that is this "intelligent".
The Luxos U incorporates a handlebar mounted switch incorporating a USB outlet for charging USB devices. It also has a cache battery for those devices that might switch off if the dynamo's voltage drops, like when standing at a stop light.
Luxos U Features:
Wiring for the headlight to the hub is included. Tail light wiring is not. See related items below.
