Mirror Ball with Platinum Beams

Dance floor lighting is always better from above, but often times you're limited to stand mounted effects coming from the side of the room.  While you can almost certainly not hang heavy lighting overhead, many rooms offer a way to hang a lightweight mirror ball.  Used in conjunction with sharp beam style lighting, you can get the effect from overhead while keeping the lights tight to the walls.  Often they are very inconspicuous until it's time to party.
