Visual Comfort & Co. Antonio Adjustable One Arm Wall LampFrom the Thomas O'Brien collection of lighting designs for Visual Comfort & Co., the Antonio Adjustable One Arm Wall Lamp is a handsome fellow with its mix of finishes. The matte black or antique white metal shade hosts a line of perforations along its base as a subtle design element. The brass key on the arm unlocks to allow the shade to be raised or lowered as needed. Try a pair where good lighting and good looks are both important. 4. 5"W x 7" 17.
