So far I have found CFL's good for only one thing.  My wife sells 
vintage jewelry on the internet. The 6000 degree color temperature CFL's 
are excellent for use in a white box to photograph her jewelry.  I use 4 
of the 40W equivalent bulbs to illuminate the white box.  The jewelry 
stands out against a completely white background.
