I use compact fluorescents in those places where access is difficult (ceiling fixtures in hallways and pantry) and in places that Marcia (who hates them) doesn't use, such as my study. (She doesn't like the color, which I find unobjectionable, and she doesn't like the fact that they don't come up to full brightness instantly, which I
do find a bit of a bother, but not much.)
I like them because they last
much longer than incandescents; the 60-W bulbs in our dining room chandelier, for instance, seem to last no more than about six weeks on average. (But that's right: they claim 1000 hours, and we leave them on about 18 hours a day.)
On the other hand, the light in the pantry, a compact fluorescent, hasn't needed replacing in over four years. So even if they cost twenty times as much to buy, their overall replacement cost is lower -- neglecting lost investment earning opportunities, of course.
And they
do save money on electricity; a compact fluorescent with the light output of a 100-W bulb consumes about 26 W, so they save you 74% on power.
