Architect George Nelson, who was Herman Miller’s design director from 1946 to 1972, said: "Every truly original idea seems to find its most important expression in a chair.” And then he blew the doors off lighting design. When Nelson was outfitting his office, he coveted a silk-covered Swedish hanging lamp but found it prohibitively expensive. He then recalled seeing a photo in the paper of Liberty ships being mothballed "by having the decks covered with netting and then being sprayed with a self-webbing plastic,” said Nelson. "And then, Whammo!” Inspiration struck, and by the next night, Nelson had designed his first Bubble Lamp® (1947), using a spray coating of translucent plastic polymer over a skeleton of steel wire. "When you put a light in it, it glowed.” A wide range of shapes and sizes are now available. UL Listed. Bulb (not included): incandescent 150W/120V/E26/A21 max. Made in U.S.A. The Nelson Triple Bubble Fixture Kit (sold separately) accommodates three Nelson Ball, Cigar, Pear, Saucer or Lantern hanging pendants that are 19" in diameter or smaller.
