We switched to compacts fluorescent (the swirled kind) years ago, but we did find
out fast that to get the BEST "true" lighting from the CF's that you needed to get
the 6500k DAYLIGHT kind (they have a brighter white), otherwise your lighting has
a yellowish haze.
We haven't purchased any incandescent bulbs since we switched everything over.
I have to say we are VERY happy with the CF's.
