My high-ceiling living room has only 3 plug-in lamps, but there are two live, switched electrical boxes on the wall, a few feet apart, just above top of the bookcase in the photo below.
The easiest place to put fixed light fixtures is on the wall immediately over the bookcase.
What type of light fixture might provide the best light for the room, if put on the wall above the bookcase? (By best, I mean general light throughout the room.)
