If the light is going to be off most of the time (as many lights
in an average household are), a C.F. won't save very much electricity
annually.  In this case you can get better interest for your money by
depositing to a bank than by investing to an expensive C.F.

Also, in some areas of the world you have to heat your house anyway
for several months of the year (this is the darkest season, too),
so the extra heat generated by the conventional light bulbs will
not be totally wasted.
