The Nelson Bubble Lamps by Herman Miller are beloved pieces of mid-century modern design. Made with a spray-coated plastic originally made for the military, the Nelson Saucer Wall Sconce features a disk-shaped steel frame that is slightly visible through the shade. The shade is attached to a Brushed Nickel Arm and Walnut mount, and is adjustable left-to-right and up-and-down with the help of a long cord and counterweight.
