Ahh this is the ballast to those old lights? Looks like a newer Advance. Probably from the 80s sometime. Looks like a newer one but I don't think Duro-Test was around in the 90s. they were gone before that IIRC.

It is very old it is the same age as the fixture

Yeah, I believe that's the mid 80s to mid 90s Advance label design. IIRC Duro Test was still around in the 90s but I don't know when did they stop making lamps.

But why would we give it a new ballast and lamps when they got no power to them.. 70s

Here's the thing, 70s and early 80s Advance ballasts had this style label while the ones from the mid 80s to the mid 90s has a label that looks like the one in your pic.

Is there a possibility that when the basement was shrunk, these fixtures were installed and they had reused the lamps from the older fixtures? You had said that they partitioned the basement at one point and maybe these lights were installed and no one ever got around to hooking them up to power?

It is shrunk 27 years ago so It was given a new ballast? the wires in the fixture are not cut this would mean a new kit was put in 1987. I just don't understand why you give a light a new ballast with no power to it.

If there are no cut wires then that means the ballast is original so these fixtures must have been installed and they were never connected. Someone probably forgot to connect the new fixtures since that part isn't used by anyone.

Ballast kits are very popular for us
