Do far my experience with CFL's has been very poor.  I mark the date in 
service on each one as I install it.  6 months is the longest one has 
lasted with a couple a little as 2 weeks.  Overall, I would rate them as 
more expensive than incandescent bulbs.  Reduced power consumption does 
not offset the initial price.  I am going to have to replace two more 
100W equivalent ones this morning.
