This is the Cree XR-E led that many people are talking about. I read that the current generation are even more efficient now at 80 lumens/watt. The controllers are listed under "High Power LED Drivers" on the left hand side colume. They will still have a "cool white" fluorescent light type color.

Those prices look pretty good and I'm sure those regulators would allow for dimmability. I think 80lumens/watt is maybe a tad optimistic but surely possible if you have enough heat sinking. I would think most users would want to avoid the heat and just use extra LEDs. The new generations of LEDs color shift a bit as you change drive current starting at green and eventually shifting to blue. Somewhere in the middle you get white, that's why they bin them.
