Long life power efficient light bulbs are worthwhile whatever you think of the collateral political/enviromental issues.

I gree with you. There are lots of reasons for trying these other than "saving" money.
The bulbs all carry a guarantee of longevity, which I've never pursued, but I plan to.
At 25% the energy consumption of incandescents, my (almost) 100% fluorescent lighting home does not "feel" any different than before.

"The bulbs all carry a guarantee of longevity, which I've never pursued, but I plan to."

Don't bother. They do NOT live up to their advertising for long life. The "guarantee of longevity" is probably just "free" replacement when they fail prematurely---which costs more in time and effort than any possible "savings".

I've been SERIOUSLY disappointed in their performance, "life-cycle" wise.
