When I built my shop 8 or 10 years ago, I bought used 8 foot fluorescent fixtures that were removed from a store. They use the single pin T12 tube. The lights have worked fine... until a year or so ago. I now have quite a few that are not working. And... it sounds like they are phasing these tubes out.
I need to start repairing or replacing them. I would prefer to upgrade the existing fixtures to a newer electronic ballast and tubes, if possible. Can I upgrade these fixtures to the T8 ballast? Do they make a single pin T8/ 8 foot tube that would work with my existing lamp holders/ or do they need to be replaced as well?
any ideas what my best options are? (cost /light output / etc.) ....btw, I have around 25 fixtures that will eventually need attention.
here is pic I happened to have that shows some of the fixtures when they were all working...
