Spring is slowly making its way to my neck of the woods and I'm getting ready to start my seeds for the garden, but I need some lights. At the salvage building supply I've found a few fluorescent light fixtures that have white, black, and red wires coming out of the balast. How can I rewire these to use a plug? Is the red wire a ground? Would I follow what is said in the "How to replace and extension cord plug" article?
