I'm cheap and lazy----That Edelux light cost more than my bike!....Shimano Alfine hub with a Cree 3 watt MR16 and a Planet Bike 5 led blinky in back.....more than enough light for me on the road.

Anybody that would pay $300 for a $6 led and some plastic......

Avenier makes a pretty nice shaped beam 3 watt light for about $35 if you can find one in the U.S..I've only seen them on EU sites.Has a standlight and all.
