I'm about to build several single emitter 3 watt bicycle headlights, and am wondering what the current standard is for power LEDs. It used to be Luxeon years ago, and I have been hearing about Cree a lot. Is Cree the current baddest and brightest? ...or is somebody else the Candella King?
Also, who has the best optics? I'm wanting a 15x5 degree (somewhere about) eliptical spot.
