The Ball Bubble Pendant, a 1952 George Nelson design, is a classic "must have" piece of design history that has transcended both time and trends. It features architect George Nelson's fresh solution to lighting design in the organic form. The lamps were first produced by spray-coating a skeleton of steel wire with a layer of translucent plastic that cuts glare but allows light to softly shine through. The tautly stretched White plastic polymer emphasizes the simple form and sculptural qualities of the lamp. The Ball Bubble Pendant is available with a White plastic diffuser, Stainless Steel finish, and the following options: Sizes: Small, Medium (shown) or Large Lighting: The Ball Bubble Pendant provides beautiful diffused lighting.
