One of them is a green wire in the broken pipe, though. If green is supposed to signify the ground...and the red is normally the hot, where's the neutral? I don't see a neutral. [Linked Image]

Also, what's in the grey/white box that that ceiling light (which is what it is) is bolted onto?

I've seen fixtures like that in someone's room (without the concrete block, of course [Linked Image] )
