You are forgiven <g>.

The cost of CF's is about $1/watt. A 20 watt bulb and ballast is about
$20.00 at Home Depot. You can get 4 foot 32 watt T8's flourescents for
$2.17 from Home Depot each plus about 44 dollars for a 4 bulb ballast from
Grainger (Magnetek B432I120RH).

Many of the CF bulbs are permanently attached to the ballasts, hence you
have to replace the whole assembly. CF bulbs without ballast are about
$0.50/watt. Compare that to $0.07/watt for 32T8's.

Add it up! T8's with electronic ballast are cheaper and more efficient. $52
dollars for 128 watts. $9.00 to re-lamp.
