My CFLs haven't lasted very long since production of most of them shifted to China. They last a year or two, which is a bit longer than the bulbs they replace, but not much. There's no place to dispose of them safely though so they are just stacking up in boxes for now. I found with the warranties that you have to ship the bulbs back at your own expense to an address, which because of the weight of the ceramic base costs more than the bulb did originally. This means in practice they don't really have a warranty, so you did the right thing throwing the warranty packaging out.
