hi i am a homeowner shopping for light fixtures that i will have installed. i have not yet decided on the installer. i have 3 ceiling light fixtures that i dislike. they are all the same and are in the den, hallway & bathroom; they are 1 lamp units. all of the fixtures that i like have 2 lamps. can i install a 2 lamp fixture in place of a 1-lamp fixture? is it going to cost a lot? will i have to run \"2nd lamp wiring?\" or, can i use existing wiring? OR do you know of any sites that have attractive 1 lamp fixtures? thank you for your time.
