This ceiling lamp comes from the Triangolo series produced by Venini circa 1965. It features suspended glass prisms, designed with a surface that creates the largest possible reflections in the glass. The effect was also increased by the free-swinging prisms, which vibrate easily in the draft. 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.
