Compact fluorescent bulbs can last as much as 10 times longer than incadescent ones.
Don't buy the bargain bucket ones because they may not live up to expectations. Don't use them with a dimmer switch - most types will burn out from that - though there are now a few coming onto the market which can take it.
I've had a few of mine now for three or four years. I guess they should last six or seven, given that some incandescents manage over a year.

I imagine it depends upon exactly which light bulbs you are comparing, but in general "ENERGY STAR qualified light bulbs last 6 to10 times longer than standard bulbs, and they use two-thirds less energy."
They say that lighting accounts for about 20% of annual household electricity bills...so it's easy to see how using energy saving light bulbs would be much cheaper in the long run even though the CFLs cost about twice as much as regular incandescent bulbs.

Not too good in 2 years I have had 3 fail. Not too good as the bulbs I bought were supposed to last 5 years.

I have had my in for over a year now and not a 1 has failed.
The other good thing is I put them in my ceiling fans and I haven't lost any there either. With the old bulbs life was about every two months

"Modern CFLs typically have a life span specified between 8,000 and 15,000 hours."
"Typical domestic incandescent bulbs are similarly specified to have a life of 1000 hours."
"CFLs typically save enough money in electricity costs to make up for their higher initial price within about 500 hours of use."

i would think over 8000 hours.
the quality of the bulb matters and i am not sure , but perhaps the number of on / off s you do may affect its life also.

I'm sure I read somewhere that they last 5 years and cost about 55p in electricity each to run per year.
