You might be more happy if all the lamps put out the same color light. What brand and model full spectrum cfls are you using?
I have Home Depot GE chroma 50 (sunshine) 4′ tubes in my kitchen, and some screw in cfl’s in other fixtures, like in the bathroom. I like the light after using it for awhile, and bought some 90 CRI cfl’s for video use. No complaints about heat and they balance better with light coming in via the windows.
