I'm sorry, I thought this discussion was about whether florescent bulbs consumed less energy than incandescent.....My bad!.....:$
No, actually this discussion is about an australian ban on incandsecent bulbs. Nobody is saying they don't save energy, but no, they don't save much.

Your math is skewed, ZmOz.
Not at all.
JB said:
First of all, the flourescent replacement for a 60 watt IC is 10 watts, not 20, so they use half of the energy you state.
False. The fluorescent equivalent of a 60 watt incandescent is 15-20 watts. 10 watts is
NOT a comparable replacement. A typical 60w bulb is 900 lumens. A typical 20w CFL is around 1000-1200 lumens. A 10 watt CFL is around 500 lumens. All the compact fluorescents you find at the store labeled "60 watt replacement" are either 14, 15, or 20 watts.

Second, you state that the FL life is shorter than an IC. Not in my house, it isn't. My original reason for switching was that ICs were lasting about 6 months. The FLs have lasted 8 years, and the last time I bought some they were $3.69.
So your house is representative of all fluorescent bulbs in the world? I believe you live alone, do you not? That will have a huge effect on how often the bulbs are turned on and off, thus increasing thier life. Premature failure is a very common complaint with CFL bulbs. As I said, I have a huge box of them, all different brands, at least 20, that have failed LONG before the 5-10 years/5-10,000 hours printed on the packaging. If they lasted as long as they claim I would have never had one burn out, ever.
