You're lucky. Our earliest CFLs (Phillips) burned out quickly. Since the mid 90s I date all my CFL and LED bulbs. The next gen after the Phillips CFLs lasted about 2yrs in our kitchen where they get a lot of hours. About the same as the halogens they replaced. But the last (and cheapest) set of CFLs (Feit?) has some bulbs that are going on 5yrs now.
