In order for a CFL bulb to generate as much light as its incandescent counterpart is to use the same amount of electricity as the regular bulb. You can't get more light out of less electricity with these things.
I don't know what you are basing that on other than someone's internet ramblings about conspiracy theories, but it is incorrect. Incandescent bulbs are extremely ineffecient, because much of the energy is converted to heat instead of light. A 22 watt CFL bulb produces approx. the same amount of light as a 100 watt incandescent bulb. They also last about 10 times as long, making them cost effective both in their purchase price and energy usage. There are dimmable CFLs and they are developing low mercury ones as well.
BTW, Ollies sells these at discount prices. I am changing over all my bulbs as they burn out. The 22 watt (100 watt equivilant) bulbs appear to be just as bright as the 100 watt incandescents.
OLDFLAME is correct. We converted over to these about 2 yrs ago and save at LEAST 10 bucks a month on electric. Maybe more. I put (4) 100w equiv bulbs in my basement for the same wattage as (1) of the convential bulbs . SAME light levels. The only difference you see is it takes approx 5-10 seconds to "warm up" until they achieve full brightness. Which is the reason I love them in the bathroom: at oh-dark-thirty when I'm speaking with a man about a horse, my retinas don't get seared . I appreciate the time delay.
And we switched out all the PAR 30 flood bulbs in my outside soffit - very pleased with this as well. I believe those are 10 or 12 w as opposed to the 75w we were using.
Ceiling fans/other light fixtures are 6w or so. Multiply all the above x10 and you have signficant savings. And I'm no commie.
