Joe Colombo’s 1967 KD28 looks like a prop from a Kubrick film but lights a room beautifully — the disc-shaped polypropylene shade repositions to direct light precisely, and units stack vertically into a sculptural column. Kartell revived it with recycled materials and USB charging, so the space-age shape now carries contemporary hardware. The stacking detail means one lamp becomes a floor-to-ceiling installation with just a few more units.
