So true. My dual cree xml light is $50, outshines my DIY dynamo lights by far (and my DIY dynamo lights are already brighter and floodier than the best commercial dynamo lights available). Plus the $50 is movable from bikes to bikes, and is helmet mountable, also can be used as a headlamp for non-bike duties. That said, I'm still gonna use my dynamo lights (and I have 4 bikes equipped with dynamos and dynamo lights, cheapest being an Shimano LX dynamo).
