Giuseppe Ostuni 331 floor lamp Oluce Italy 1950

A rare and collectible example of early Italian modernist lighting, this model 331 adjustable reading lamp was designed by Giuseppe Ostuni and manufactured by Oluce in 1950. As one of the lesser-seen models from this formative period of Italian design, it stands as a prized object for collectors and aficionados of mid-century lighting.

The design is highly functional and elegantly engineered, featuring dual articulation points, both at the base and at the shade, allowing for an extraordinary range of directional lighting. The stem is crafted from solid brass, showcasing the distinctive Oluce alloy, a unique brass formulation that sets it apart from contemporaries of the period. Over time, the surface has developed a rich, authentic patina, adding warmth and depth to its material presence.

Balancing the vertical brass structure is a solid white marble base, lending weight, visual contrast, and structural stability. The off-white aluminum shade, complete with original air vents at the top for heat dissipation, retains its original paint with gentle, age-appropriate wear. The shade’s articulation allows for it to function seamlessly as a downlight, sidelight, or uplight, making this an exceptionally versatile piece both in form and function.

This lamp embodies the early design language of Oluce, the storied lighting manufacturer founded by Giuseppe Ostuni in 1945. As the oldest Italian lighting design company still active today, Oluce’s legacy is steeped in innovation and timeless elegance. Its formative years were shaped by collaborations with leading figures of Italian modernism and a commitment to both aesthetic and technical advancement.

This particular model predates Oluce’s widespread international acclaim, offering a rare glimpse into the pioneering spirit of Italian lighting design in the postwar era. Its refined materials, mechanical intelligence, and sculptural poise make it a quintessential example of Ostuni’s vision—where form meets precision in the service of light.
