This comment applies to strip florescent fixtures and not the screw-in compact bulbs. Be aware that they are not all the same. There is a ballast buried in the fixture and they can be magnetic or electronic. The magnetic ballasts are a lot cheaper but they less efficient, which is why things are shifting to electronic.
If you have florescent strip lighting don't think you are done. If they are over 10 years old, they probably have magnetic ballasts. One manufacturer claims a 40% efficiency improvement with electronic. All you have to do is touch it after it has been running for a while to realize a lot of power is going as heat.
