Do you live in a rural area? Is it possible that your power has severe
fluctuations? Frequent lightning strikes? Unfortunately, rural power isn't as
clean as urban (as a crude generalization). That could contribute to your short
bulb life.

I use Phillips and 'Globe Energy Savers' (a brand in a big box hardware store)
and get years out of them. I'd say 4-5 years is typical for me and some last
longer.
