And if a CFL fails early in its life my experience is that one really
resents having to pay so much to replace it.
I don't think that's very accurate, for 3 reasons.
1. CFLs do have early failures, and of course this is made up for by
the ones that last longer than rated life. Ie there isnt really a
problem.
2. A cfl need only function for a short time to pay off its additional
purchase cost.

3. I dont see any reason to resent the fact that some fail early, some
last longer than rated. Its how all types of bulb work.
