Today was cool! I decided to buy some 16-2 lamp cord to drop a light in my room that would run off my inverter. Luckily I work for Lowe's and got a great deal. 1000 feet of 16-2 lamp cord for 40 bucks! That's enough to wire every overhead light in my house.
To test it, I also bought a plastic overhead single bulb fixture and an outlet connector. I drilled the holes, ran the wire and wired it all up and so far it works fine. I'm only going to leave it on while I am actually at home until I can feel comfortable knowing it will not burn my house down. It is not grounded but neither are most lamps and I think the inverter would stop any craziness.
