The Electrician-Free Sconce
The first that I've come across is the Hinge Sconce from the old budget modernist standby, CB2. What's more, it's on sale for a scant 50 bones. I like the shape of the lamp, which I'm sure is meant to mimic Arne Jacobsen's AJ series, but the black is pretty clean and I could easily see one on either side of the couch offering the illumination I need.
Another comes from LA-based designer Brendan Ravenhill, and the more time I spend fantasizing about it the more I dig the Cord Lamp. It certainly juts out further into the room (two feet), but I really like how it pivots and has a kind of early modernist, industrial vibe. It goes for $170 but if you buy from Ravenhill's website he gives $20 to Amnesty International.
Finally, for those who want a classic, there's always the good old Tolomeo wall light by Michele di Lucchi and Giancarlo Fassina.You can get them at Design Within Reach for $300, which might be a bit more than I'm up for spending. But if you can't live without a bit of 80s Italian design in your den, this is the jam.
