They do last a long long time under the right conditions. :-) @S01: I just replaced two CFLs in two of my bathrooms that were almost 13 years old.

A chinese no-name brand maybe half that. Of course the chinese brands tend to die much earlier, maybe 1-2 years in my experience.

For living rooms use the warm whites for things like desklamps were you work by the light try cold whites(especially if you draw/paint) CFL’s seem to be more resilient to power spikes etc. I haven’t had one blow from a power spike/lightning strike yet, but those event’s did successfully claim the lifes of several incandescent bulbs, nothing but CFL’s in the house now.

I know you were not considering it in your calculation, but CFLs also last 8 or more times longer than incandescents bulbs. So if you just figure on replacement cost alone, not electricity savings, (and excluding inflation, etc etc), you will save money over the lifetime of the CFL (1 CFL=$7.50, 8 incandescents bulbs= $10).

I'm the opposite of you, though. I like the darkness, so my porch light is set on a motion detector. As a result, I'll bet my new CFL porch light will last for close to a thousand years. ;-) Good for you, Sadie! I’m the opposite of you, though.

If not all night - at least 4 -5 hours. We have made the switch in our home and are looking forward to the savings.

It's also a 3-way bulb and just recently moved with me from Virginia to Georgia, and still going strong.
