I was going to get regular bulbs at $2-$3 a
piece, but then I saw these flourescent bulbs that sells for $7 for a set of
4.

The cold start isn't much of a problem anymore, most of those type lights are rated
for -20 degrees start (it will list it on the package). But, the bulbs may not fit
into these fixtures. I have similar ones and the compact fluorescents won't go in,
the inner reflector has a hole that is too small for the base of the lamp to fit
through. So try just one to begin with.
