Home Depot and Lowes have 3 fixture lamps that are shaped like a 3 leged spider. They are about 9 bucks, but you have to buy the little 3 dollar plug to atach, it's only 2 wires, or just cut a plug off a old peace of electronic equipment around your pad and splice the ends and hook it up to the 3 socket fixture. There is realy nothing to it, just make sure you use the black electrical tape so that none of the wires are touching.
