Restoration Hardware modern picture light sconce in polished nickel. 30 inches long. This is a plug-in. The lamp shade rotates to direct the light as you'd like. The arms retract so you can vary the distance from the wall between 9 and 12 inches. It's in perfect condition. I'm only selling it because I'm redecorating.
Here's a link to the product on the Restoration Hardware website (listed for $400):
