In DC there's Illuminations. They represent more contemporary brands like Artemide, George Kovacs and such.

overstock.com has a lot and you can search sconces with a lot of filters (eg, bronze, 1 light, etc). Here are couple that are similar with a 100 watt bulb (sconce can be hung with either light up or down).

We like this one but 60W bulb does not emit enough light for where they will be placed. Otherwise, the price is right and I'd get them. We're having a tough time finding a wall sconce that works in our hallways. I've scoured lightingdirect.com, circa lighting, annapolis lighting. What am I missing?
