We replaced a few ballasts for a commerical customer. The customer supplied the ballasts and lamps. About a month or 2 later we were called back for more lights out. The Facility Mgr asked if any of the new failures were the ones we had done on our last visit, I advised him one of them was. He actually asked if we would replace the ballast under warranty and send the failed ballast back to Advance!! I advised him, when the customer supplies the materials the customer is responsible. We offer no warranty of any kind.
