Originally debuting in 1952, the Nelson Bubble Lamp Collection from Herman Miller was designed by George Nelson and has been in demand ever since. The Bubble Lamps' shades each emit an ethereal, amber glow that lends a soothing atmosphere to your space. The translucent polymer skin is easy to clean and stretches over the Bubble Lamps' trademark steel ribbing. The Nelson Ball Wall Sconce features parallel lines that emphasize the spherical shape. It features a seamless pull chain for easy operation and hangs from an adjustable steel arm supported by a walnut wall mount.
