If you're concerned about bulb life, use a compact fluorescent. Most
of them are rated around 10K hours. If you're concerned about cost,
use a C.F. Over the life of the bulb it will pay itself back many
times. I can not see any reason to use incandescents anymore, unless
you are getting free power.
