go to any hardware store, buy porcelain lamp sockets ... look for the 'old-style' white porcelain bulb sockets, for sticking up on ceilings ... wire them together yourself, pretty simple ... save lots of $$$ this way, if doing multiple lamps ... the one pictured, is available online for $2.09 apiece, and, handles 250volts, 660watts, just to illustrate it's economy ... :thumbsup:
