Achille & Pier Giacomo Castiglioni - Model 4017 Green Acrylic Pendant Lamp

A remarkable and highly sought-after pendant light, model 4017, designed by Achille and Pier Giacomo Castiglioni, made of vibrant green acrylic. This sculptural pendant illustrates the Castiglioni brothers' rigorous yet playful approach to industrial design, where functional clarity meets formal experimentation. The translucent green acrylic shade diffuses light with a unique chromatic warmth, creating ambient lighting and a strong graphic presence. Once illuminated, the material reveals subtle variations in tone and depth, highlighting the purity of its geometric form. The 4017 model reflects the designers' philosophy of reducing objects to their essential elements while introducing unexpected materiality. The suspended acrylic volume appears almost weightless, with clean lines and balanced proportions showcasing the Castiglioni's mastery of visual economy. Its bold colour and minimalist silhouette make this lamp particularly suitable for modernist, postmodern, or contemporary interiors. It fits perfectly above a dining table or as a central element in a space reminiscent of an art gallery. A rare example of mid-20th century Italian design, this Design/One 4017 pendant is both a functional light fixture and a collector's piece. Dimensions: diameter 36 cm, height 24 cm.
