This rare pendant lamp, with its timelessly modern, 1960s Space Age design, comes from the German manufacturer ERCO, for whom such great designers as Alois Gangkofner, Roger Tallon, and Ettore Sottsass have worked. The smooth-running mechanism with the cylindrical counterweight allows the lampshade to be positioned at any desired height. This is particularly practical for all areas where a variable lighting height is advantageous. There is enough cable that the lamp can be lowered to a height of approximately 2 meters if necessary. 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, Up to 250V (Europe/UK Standard).The wiring of this item may be original and might need replacement, if not specified otherwise.
