When I first read this I thought it was the black one you got rid of.
Back when dad was still alive, I came home with one of the really old fluorescent round one, with two circular bulbs. and dad said :
What the hell are you going to do with that?
I said put it up, the ballast is good.
He said I was damn glad when the old one burnt out and now you bring that damn thing home.
He had replaced it with a cheap, and I mean cheap, one bulb thing.
That was near forty years ago and it is still going strong.
