The first prototype of the lamp was designed in a matter of two days. Nelson created the spherical frame with perforated rings that were inserted with steel wires, a construction that retained its shape under tension, required minimum tools and no welding costs. It was then sprayed with the resinous lacquer to form a fibrous web, and a final coat of plastic was applied, creating a smooth, translucent skin. And hence Nelson had added lighting installations to his expanding portfolio of work and introduced a beautiful, timeless lighting fixture to consumers at modest prices.
