very little difference especially if you change some of your normal incandescent house lights with cfl I run 8 26 watt cfls and 12 40 watt 4 ft flouros and hardly notice much difference so i doubt 6 cfls alone would be noticable .
My bill went down.
I could not believe it.
I guess it was from when we had to run the heat some the month before last.
Yeah 8 26w cfl's might be like 3 dollars or something really insignificant.
The fluro's in general do not use much power at all.
