I'm interested in energy efficiency, which is why I have been gradually replacing the incandescent light bulbs in our house with compact fluorescents, or CF's. We had already been using fluorescents where possible, usually tubes or circular shapes, but now that CF's have gone mainstream, almost any incandescent bulb is a candidate for replacement. The difference in energy usage is phenomenal. I have been replacing 40W bulbs with 9W ones; 60W with 13W and 100W with 23W. I'm amazed that the light output of the new bulbs is just as good as the old ones. It really shows how much energy is wastefully and undesirably used to make heat in an incandescent bulb.
