Danny,
We went a little nuts on lighting, so what we have is way over kill for the size of the cabin. For overhead lighting we used WAC Linear track lighting, with some of their cabinet or cove fixtures. The track itself is only 3/4" wide by 3/8" deep. The light fixtures hang down another 1 1/2" to 2". We also ended up using the same track and fixtures on the inside of the galley hatch for overhead lighting.
For reading lights we got some swiveling lamps from Camping World (which I can not find in their online catalog). These swivel down for reading or up for general lighting. In addition we mounted some small sconces near each door. These are standard household lights with 12V candelabra bulbs.
Here are a couple of pictures that show the lights. The first shows two of the reading lights in the up position, one wall sconce and one of the overhead tracks. The second shows one of the wall sconces turned on and a reading light pointing down for reading. In fact there is so much light when all of these are turned on, that we normally only have one light on in the cabin. That's plenty for reading.
