In 1963, Franco Albini and Franca Helg started experimenting with plastics in lighting for Arteluce. Summoned by Gino Sarfatti to research the possibilities that new technologies and materials were providing, the two designers came up with a suspension lamp that summed up the two souls of the Arteluce brand: the love for glass, which they used for the opal diffuser, and the daring use of methacrylate, a (then new) lighter and more resistant material, perfect to interpret modernity by combining craftmanship and industry.
