Re: Another thread about fluorescents
It seems to me the ones with yellow wires are used for tubes with two pins on each end.
I don't know much about ballasts so maybe they can be used on both types.
There should be a wiring diagram on the ballast label. If you need to, post a picture of the diagram and perhaps we can help you out with it. Also note the number and colour of wires coming from each of the sockets.
