I just bought a bunch more of those compact fluorescent bulbs yesterday. The package says that they are 5 year bulbs, but we have not had any of them last more than 2 years at the most. We have only lived here for 4 years, and I know there are several that I have changed multiple times. Not that I really care, but it is a little annoying considering that they are so expensive. What are we doing wrong? I think it must be the wiring in our house.
