A striking Italian Space Age pendant lamp featuring an adjustable "saliscendi" (rise-and-fall) coiled cord mechanism, dating from the late 1960s or early 1970s. This dynamic ceiling light is centered around a white lacquered metal dome with a perforated top grille for heat dissipation, surrounded by a frosted white glass ring. The defining feature is its large circular glass disc decorated with a bold, hypnotic black and transparent optical radial pattern that creates beautiful graphic reflections when lit. Supported by a minimalist black three-arm structural frame, this iconic piece perfectly embodies the futuristic, pop-inspired lighting design of the era.
