The life expectancy rating on light bulbs is about as misleading as the mpg rating on cars. If a light bulb is expected to last 10 years that actually means that, in lab tests, 50% failed by that point. So half the time you can expect your bulb to die before 10 years, and half the time you can expect it to die after. The number of on/off cycles does affect CFLs because they have small electrical components that wear out with use. Thanks for reading AskPablo! Thanks for the comments Sam!

Unfortunately, one chink in the armor of the math for CF bulbs is that they don't always last that long. there seem to be some assumptions about longevity that don't measure up in our usage. they seem to do better in places that are left on for long periods of time, rather than the closet with the quick on/off. or perhaps I just got a bad batch at some point along the way. Anyway, out of about twenty five bulbs in our home, I'd guess I've replaced eight to ten in five years. We’ve been using CF bulbs almost exclusively in our home for about five years.
