    This was the model that we needed. The wiring was updated. A good full sized diagram was provided. We learned we could use T8 instead of the older T12 bulbs. This was a complete success!

    Though now regarded as antiquated technology and hard to find, the product was priced exceptionally low, almost as if a gesture of generosity.

    Very easy to match old ballast with the correct replacement matching numbers and pictures.
