Well, you often need the fan at night down here in Slower Lower
Delaware, and NOT the light! Best bet is one of those Hunter radio
control gadgets that allow you to power up the whole mess, then
separtely control lights and fan with a hand controller. I've found
them especially helpful in "after the fact" fan installations in a
couple of houses over the years when all you have is a single switch
for an overhead light, and want to put both a fan and light in place,
without having to redo the wiring, etc.
