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

out of pretty quickly.

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

thanks for your input,

There is no Thought on if cfls are more efficent, they are in fact
75-80 % more. Replace them first where you save the most.
