You can make any lamp into a DC lamp to run off of the solar system in your Earthship. You do need to have a DC circuit in place to wire into. I bought this glass and metal lamp at a yard sale six years ago, waaaay before I finihsed my house. If you have DC monkey face outlet you can just snip the plug off any floor or desk lamp and rewire the end with a DC plug, put a DC bulb in the socket and VOILA! you have DC lamp. In this case we wire directly into the ceiling and put a 25W DC bulb inside.
