Nobody seem to have mentioned the very poor power factor that most CFLs operate at – somewhere around 0.5 I believe. While this may not concern individuals who are only paying for kWh the cumulative effect in the supply network means there can be lots of reactive power to provide. The fact that they cannot be dimmed makes them unsuitable in many applications. Fittings designed for CFLs seem to be a long time coming which means more light is often required to achieve similar useability becasue much is wasted by the poor optics of the fitting
As per my knowledge, CFLs consumes lots of power and electricity which can increase our electricity bills. Thats why it would be really a great idea if we use LED lights compared to CFLs.
Hello friends,
CFLs also help to reduce greenhouse gasses, other pollutants associated with electricity production, and landfill waste (because the bulbs last longer), they are clearly the environmental winner when compared to traditional incandescent light bulbs. Switching from traditional light bulbs (called incandescent) to CFLs is an effective, simple change everyone in America can make right now. Making this change will help to use less electricity at home and prevent greenhousegas emissions that lead to global climate change. Lighting accounts for close to 20 percent of the average home’s electric bill. ENERGY STAR qualified CFLs use up to 75 percent less energy (electricity) than incandescent light bulbs, last up to 10 times longer, cost little up front, and provide a quick return on investment.

A CFL will beat an incandescent bulb any day of the week. But we can’t make this a competition between the CFL and its predecessors. There are more efficient solutions available and we do have the technology AND responsibility to topple the CFL with a light that is more energy efficient, non-toxic, and easier to recycle.

Hello, i am glad to read the whole content of this blog and am very excited and happy to say that the webmaster has done a very good job here to put all the information content and information at one place.
Original article & discussions are interesting. But one point appears to have been missed. In the areas of colder climate, the apparent lesser efficacy of the Incandescent Lamp is not a serious drawback as the consumers are using other hear sources for space heating. In fact Incandescent lamps should not be banned in some of the state/countries with a significant low temperature period requiring constant heating.
Very interestig topic, the only abjection about the use of CFL is that as far as I know some of them can not be used in eclosed lamp
