Hey Karlin
I appreciate that your heart is in the right place with regards to environmental integrity.
However it seems you may not be aware of other threads on this site on the subject of mercury toxicity.
Having been made extremely unwell by exposure to emissions from broken cfl bulbs while working in property development I would very strongly advise anyone against using any kind of bulb containing mercury. If left undetected these products can leave buildings contaminated for decades and cause a wide range of severe illnesses.
Bulbs don't often get broken but hey it happens. Any potential saving in energy cost for years would be wiped out by even one breakage. It can cost upwards of 2000 dollars to get your house properly detoxed if it happens. Why take the risk ?
If you have any installed in your house or office remove them and wrap them in very thick layers of newspaper, then several layers of plastic or other airtight container. The trash men don't want to breathe it in either. If you break one in your house you should evacuate the house and get advice from an environmental protection agency of some sort.
Fortunately the industry has already responded by developing low energy LED bulbs and anyone who wants to save money on juice should move straight onto those instead which are mercury free.
