Worth,
We had similar problem in our house in WI. Originally we had just a ceiling fan in the cathedral ceiling of the living room. When we added a light fixture on the fan we added also a remote control, which allowed controlling the light and the fan and its speed.
Thanks posting those links lefolly. There is a lot to read and try to understand.
I believe I have to study this thing much more before spending more money on different color LEDs. There are so many opinions on different forums on the net that it is hard to find the real data on the issue. I just thought that the pure white LEDs could be good after reading a test made by one Finnish chilehead. He got much better results with pure white LED lamp compared to red/blue lamp, which had much more red than blue.
