Are you sure about that?  Those old magnetic ballasts weren't very good and
there are still a lot of them around.  Their power consumption doesn't
usually get included in the fixture rating; while the CFL does.

Also had lousy power factor, which means the loss in the wires is higher
than it would be otherwise.

Or by "classic fixture", did you mean one with a modern, electronic ballast
and high efficiency bulbs?

I'm slowly changing out the magnetic ballasts in my garage/shop, and it's
not unusual to find discolored paint from the ballast getting hot.
