While some may argue over the numbers there clearly will be some issues with
small group(s) with a mandatory FL/CLF world.  It will be interesting to see
if high efficeincy incandesents prove out and are available as a subsitute.
Current rules do not support thier use.

There is a parallel here to asmatics.  New inhalers are all CFC free, and
are clearly not working as well as prior versions.  There is no exception to
the CFC ban, even for demonstrable medical purposes.

FDA approval is not requried for it, but is generally considered effective
by most professionals working in the field.  See the links to the Mayo
Clinic and Columbia Univ. below.
