It is inaccurate to say that 95%of the energy generated by a traditional light bulb is wasted, this is heat that is dispersed around your home the same as any other heat source, so if you remove this you have to replace it using more of your oil, gas, etc. in winter.

Also cfl bulbs in my experience do not last nearly as long as the manufacturers claim even under normal working conditions, this should be the focus for debate, the quality of the product and the price not just sweeping statements about energy saving light bulbs, I have a house full of these bulbs but I think we are being conned by the manufacturers.

Editorial Comment:

"cflblues" is assuming you already have calculated in the need for several hundred watts of extra heat from light bulbs into your heat loss calculations. He/She has also conveniently forgotten that in summertime you could do without those extra heat sources. In fact you might be using extra power, by way of air conditioning, to get rid of the surplus heat.

My calculated experience with CFL bulbs is that they last well up to the manufacturers specifications. I date a cfl bulb with a pencil mark on the white plastic base, so when it fails, I have an exact days in use, plus a reasonably accurate calculation of hours in usetime.

I fear that "sweeping statements" without much scientific basis, is exactly what "cflblues" is indulging in him/herself while appearing to blame others for it.

Finally, I have NO DOUBT WHATSOEVER that CFL Bulbs save money, time, and carbon emissions. They also give a superior quality of light, and are safer in use, they will not cause a fire if a curtain should blow over a lighted lamp. I say go for them and save yourself a packet and the environment at the same time.
