As I said, the decorator used this flat wire and plugged something into the receptacle below the sconce light. ( Excuse me Luminaire )(Did I spell that right?)

Anyway, the website states that it is low voltage but on the TV show it looked like line voltage. Needless to say, IMHO putting wiring on the wall and painting over looks like you could be in for trouble if you want to hang something on the wall right below the new sconce light.
