In my entryway, there is a lighting fixture box that is sticking out of the ceiling drywall. (See attached image below) The box is 4 inch by 4 inch. I assume that it came with some kind of ceiling light that included the box as part of the hanging fixture. I assume this because I can't find any ceiling light in stores today that would fit over it. But I also can't find any ceiling light that comes with a box like this.

When I bought the house, there was no light here, but now that I am selling it, I want to put a light up. If I can find a light that works with the existing box, that would make things easier. Otherwise I guess I have to take that box out and put in something else to put up a new light.

Anyone ever seen lights that use this kind of box for hanging? Is this more of an old style light that is no longer made? All the lights I see now are either recessed or flush/semi-flush which wont work with this box as it sticks out of the ceiling.
