I have never had a CFL burn out yet in several years of usage. Many have
broken or came apart from the base and leaked.
Compared to incandescent, CFLs in USA on average reduce mercury
contamination of the environment.
Burning coal is a major source of mercury pollution, to such an extent
that a CFL successfully replacing a 60 watt incandescent and lasting over
5,000 hours, or successfully replacing a 100 watt incandescent and lasting
over 3,000 hours, achieves a reduction of mercury pollution - even if the
CFLs are not disposed of properly.
Meanwhile, they can be. I have heard that Home Depot accepts dead CFLs
for proper disposal. There is also www.lamprecycle.org.

What brand are you buying? I've had a bunch of Sylvania and Feit CFLs
burn out -- but I've had Sylvania incandescents that lasted only a day
or less too.

I have had every brand made, I think. Sylvania,Phillips, GE, Globe, and a
miriad of brands I have never seen before. I am not sure which ones had
problems. I have had some DOA units too in 6-packs. I have had units that
took 5 minutes to brighten so you could tell they were on when I lived on
solar power, on cold days.
I sell old units to Jewish people for weddings. Nobody knows it isn't a
wine glass breaking inside the bag...LOL

Have you actually seen mercury leaked from a CFL? I doubt it - the
quantity is very small.
Meanwhile, I have extensive CFL usage, and never broken or cracked one
unless I dropped it. I have seen one CFL that cracked during use, among
hundreds of burnouts that I have had a chance to see.
I have had a few come apart at the base during handling - like 2,
with one additional having the tubing come loose from tubing end
overheating while approaching burnout, with none of these 3 having
the tubing break, while I have had more burnouts than that in my home
since 1990. Both the ones that had their bases coming apart were dollar
store stool specimens of usual dollar store brands.
