Jieldé

SI333

The Jieldé SI333 is a defining piece of French industrial design, first introduced in the early 1950s by Jean-Louis Domecq. Designed to meet the rigorous demands of factory work, Domecq’s lamps were engineered with a patented joint system that eliminated the need for internal wiring, making them remarkably durable and flexible. What began as a practical tool for workshops quickly became an icon—admired for its engineering, character, and timeless silhouette.

Today, the Jieldé SI333 remains one of the most recognizable designs in the brand’s Signal collection. Still handmade in Lyon, France, each lamp is individually numbered, underscoring its authenticity and connection to a living design tradition.

French Industrial Design Refined

The SI333 is characterized by its three articulated arms, which can be adjusted with precision thanks to Jieldé’s patented pivoting joints. This innovation allows the lamp to move fluidly into countless positions, making it as functional on a modern desk as it once was on a factory bench.

Constructed from steel and aluminum, the lamp is available in a wide range of hand-applied finishes, from understated matte black to vibrant colors and metallic tones. Its exposed joints, metal shade, and sturdy base reflect its industrial heritage, while its clean proportions and scale make it equally at home in contemporary interiors.
