A very small thing I have not reconciled in my mind regarding flourescent bulbs saving energy and reducing pollutants, don't they have some sort of other nasty thing in them? I was told it is not wise to dispose of them in a land fill because of the stuff they contain.

Also some do not have the long life they are supposed to have. I've used them for the past 3 years and have already had to replace 2. I sometimes get that long a life, or more, from an incandescent bulb.

Although one gets heat as a supposed by-product of incandescent bulbs, in my house that heat is not wasted, as I derive benefit from that heat in the winter. A heat source is a heat source, is a heat source.
