Designed by Afra and Tobia Scarpa in 1963 for Flos, Jucker table lamp is made of two hinged spheres, the inner rotating on a vertical axis while the outer over a horizontal one. The result is a lamp that can be adjusted to let through as much light as desired. Jucker lamp has been defined as simple, inexpensive and flexible. While the lamp has been discontinued by Flos in 1995, it is considered a collector item and a very iconic piece from the 60s.
