    Worked out great. Hooked it up the same way I took out the old one. No problem. Easy to order. I just typed in the numbers on the old one and this new replacement one came right up. Three days later I received it.

    Replacement ballasts

    I put in the type and serial number of the old ballasts and the new replacement ballasts came up. Order them and had them installed by an electrician. They work perfect.

    I had never replaced a ballast before and found that it couldn't have been easier after viewing a demo on YouTube. Worked like a charm!
