I hope you are talking about the tube, right?
I went to Lowes and bought a 24" fixture, then bought the cord in order to adapt it to a plug. Most of the fixtures only have the 2 naked wires coming out because they are typically wired into the electrical system for a switch, not a plug.
Even if you technically challeged it is pretty simple to get the wires attached. If you still can do it then you may be able to find a friend or neighbor willing to help out.
