Does anyone have any thoughts on 12VDC lighting? I have not put in the interior walls yet. We are thinking of light wood paneling. And we have seen some 'sconces' that hold an electric candle. But we have been loosing power about twice a day for the last three weeks. So I am wondering about putting more of the circuits as 12VDC fed from a battery bank. Is there a high efficiency 12VDC light?
