PH 3/2 Wall

The PH 3/2 Wall Lamp is part of Poul Henningsen’s pioneering three-shade system, originally developed in 1925–1926 in collaboration with Louis Poulsen for an exhibition in Paris. This long-standing partnership continued until Henningsen’s death in 1967 and resulted in one of the most influential lighting systems in design history.
Guided by a scientific approach to light, Henningsen sought to eliminate glare, direct illumination where needed, and create soft, balanced shadows. Using the principles of the logarithmic spiral, he achieved an even distribution of light across each shade, ensuring both visual comfort and functional precision.
The three-shade system evolved into a comprehensive family of designs, with around a thousand variations produced over time, including table, floor, wall, and pendant lamps, as well as chandeliers. The PH 3/2 Wall Lamp is one of the system’s “hybrid” models, combining a top shade of approximately 30 cm with smaller lower shades derived from the 2/2 configuration—designed to suit more flexible placement and proportions.
Crafted with layered opal glass shades, the lamp emits both downward-directed and ambient light, softly illuminating its surroundings. A timeless design, it reflects Henningsen’s enduring vision of merging scientific innovation with refined aesthetics.
