Given, CFL's are thought to be more energy efficient than incandescent

What if it is in a room that is used infrequently, a closet or guest
room for instance. In other words a room in which you would go in and
out of pretty quickly.

How long would a CFL have to be left on to realize the net energy
savings.

thanks for your input,

Mythbusters did a segment on that. The break-even point was something
like 6/10ths of a second.

The better question is, is this really a question considering that you
aren't going to be able to buy incandescent lights next year.
