Balancing Counterweight table lamp from the Italian manufacturer Lamperti. A very simple yet exciting design. The ball and illuminants form an optical and real balance. The weight in the ball can be updated again and again. There are also designs on this principle from Enzo Mari, Cosack and other manufacturers. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution, European Plug (up to 250V).The wiring of this item may be original and might need replacement, if not specified otherwise.
