I am putting in an electrical outlet behind a wall and I am looking above the wall by moving a ceiling tile. After moving a ceiling tile, I found that there is a light wired behind the ceiling tiles, a place nobody would be able to see it. I can't see where to turn this on, and it is not a problem, it has just made me curious. I live in a 95+ person fraternity house if that makes any difference.
The light used to be on the finished ceiling when the structure was first built. Later a drop ceiling was added and they just left the old lights up there. They were probably controlled by the switch that you currently use to turn the troffer lights on that are mounted in the ceiling grids.
