The mighty quad k2 Generator light. It might not be pretty but man o man does it light up the road nicely. The two bottom lenses are 3 degree spots aimed to throw light doen the road, Left top is to throw light a little closer in and the one right top has a 4X14 degree lens to provide some "be seen" light to oncoming cars.
Below is the mighty Quad K2 Generator Light!As you can see there is a lot more light thrown out by the K2 at a feed of 8 volts. The Shimano Dynohub is capable of outputing 12v (as does the schmidt) at higher speeds so the beamshot at left is actually not as bright as it could be.
