Trained as an architect, George Nelson found a fresh solution to lighting design in the organic forms of his "bubble" lamps. The lamps were produced in 1952 by spray coating a skeleton of steel wire with a layer of translucent plastic that allowed light to shine softly through and protected the eye from glare. The tautly stretched plastic emphasizes the simple forms and sculptural qualities of the lamps. UL-listed. Bulb not included: incandescent 150W A19. Made in U.S.A.
