quote:Originally posted by Alan Franzman:I know that some of the members here collect items other than light bulbs, such as electrical plugs, sockets, lamps and related items. Do any of you have, or know if there was ever available, an adapter for a medium-base 3-way bulb to be used in a mogul-base 3-way socket?My mother has an antique lamp with a 3-way mogul base socket, in which she's currently using a mogul-base 3-way incandescent 150 watt bulb. (I'm somewhat surprised these are still available!) Due to the heat and inefficiency, she would like to use a fluorescent bulb. I have a mogul-to-medium adapter but it's not 3-way and I can't seem to find any that are. Though the lamp will work this way with a standard fluorescent bulb, she really would like to keep the 3-way function of the lamp without altering it if possible. I already have both standard and 3-way circular fluorescent bulbs available to use.

A 3-way bulb / socket differs from a normal one by the addition of a 3rd contact, located around the perimeter of the center tit on the bottom of the socket.The outer shell of the bulb is the common electrical connection point for the 2 filaments inside the 3-way lamp. One filament is powered at the 1st "click" of the switch, the seconc "click" turns OFF the first filament and turns on the secondary. The third click turns the 1st filament on again, and the 4th turns all off.
