After reading Rick's comment if occurred to me that the base of a CF would
get much warmer when the bulb is upside down which would shorten the life of
the components inside it. Maybe some CF bulbs are made to tolerate a warmer
base, probably not the cheapest ones.

Buy "Cans" built for CF!

Most of the problems with home CFs are actually with the tiny
electronic balast in the screw-in base.

Fixtures whether cans or anything else that are built for the bin-base
CF lamps have larger, better and more reliable balasts built into the
fixtures. All recessed fixtures makes have cans that are designed for
CFs and make the best use of their diferences.

P.S. Also consider putting some light that shines up onto the ceiling
or really covers one wall. Recessed only can make a dark room look
smaller and darker than it really is.
