[Cicero]

I use energy saving light bulbs throughout the house. It's one practical and very simple thing you can do to save power. They use around a quarter of the power that a regular bulb uses for the same amount of light. The price is now fairly reasonable, especially since they last much longer than incandescent bulbs.

Ditto here. The only drawback is those bulbs don't work for ceiling sockets. I may buy a led bulb and see how it works for a hallway. I don't think the led ones are bright enough for general purpose room lighting.
