Hmm... Yes, like the old floor lamps that had 3 standard base sockets and
one central mogul base socket. I wish I still had one of the really nice
ones that my parents had. It was a beautiful lamp with marble base and
engraved bronze post. An adapter could be put in the mogul base in order
to use a CFL there, too.
We have several true antique tiffany-style glass and craftsman style lamps
with mica shades that have either 2 or 3 pull chain sockets in them.
However, I still use clear incandescent bulbs in them because the CFLs make
them look extremely dull. I have thumbwheel dimmers on the line cords and
I use slightly higher wattage bulbs than one might want so that when dimmed
they give a much warmer light.
