if you want a 1W dynamo powered light output, it's going to require at least a 1W input from the rider. friction, or the losses incurred by the dynamo in converting kinetic energy of the wheel into light, will require even more input.

friction isn't really the right term to describe energy input for a dynamo light. there will be some friction, such as in the dynamo bearing/bush.

Low-drag is a more appropriate term, and maybe very low drag for the Reelight.
