The Freeplay alternator rather crudely attached to a bike, powering a cluster of 7 LED's - capable of 16 watts,efficiency 50% twice that of standard cycle dynamos.
The nearest rival is the Busch & Muller S12, that sells for an astonishing $600 US)

wow, actually twice as efficient as the next best model - and so cheap.
it's amazing that they aren't supplying alternators to the bike dynamo market. That's a rich business opportunity sitting idle right there.
