I am inexperienced with dealing with electricity and wiring. I have wired the old T12 ballasts (8') in and they have worked fine. I recently purchased new ballasts for 4 lamps where the ballast has burnt out. I have heard that the T12 ballast can be converted to the T8 ballast that I now have, i just dont know how. The old ballast had one white, black, blue, and red wire. The new ballast has two blue, one white, black, and red. How should the new ballast be wired in? Sorry if this sounds like a dumb question, I just dont want to short anything out or burn up the new ballast too fast. Thanks.
