I've never had a compact florescent light last me more than two years,
and they often fail within six months. Given the amount of stuff in one
of those, which implies a lot of energy expenditure to manufacture, I
question the notion that you'll really save anything over the life cycle
of the bulb by using incandescents.

(and, compact florescent lights use mercury, and become a hazardous waste
issue the instant they enter your door -- assuming free manufacture, I'll
trade off the inefficiency of an incandescent light for it's safety any
day).
