I'm happy with my B+M ixon iq light on my recumbent bicycle but some people need more light, for example when cycling through the woods in Finland: Jukan put together a 24-watt 1680 lumen led light monster.
Found via Unreasonably bright bike light apparently hunts deer - Hack a Day (although the deer that seems to be in the resized picture is some bushes in the original picture).
