a socket on a cord, even better!
the 99p stores or poundland sometimes have a socket on a cord which plugs straight into a uk mains plug thingy (i say sometimes cos their stock varies all the time, and in my part of uk neither had one about a week ago, but again woolvorths saved me as they sell the same light bulb socket on a mains cord but for the dearer price of 3 GBP

they are htese white (HUGE clothes peg) clip things attached to a socket and a wire, if you ask the dudes there if they got a thing to put the bulb in they should show you one.

oh yeah the CFL in the ebay thingy looks okay...
