Louis Poulsen PH 3½-2½

Designed in 1928 by Poul Henningsen, the Louis Poulsen PH 3½-2½ collection is a continuation of his celebrated three-shade system, a pioneering design that transformed electric lighting in the early 20th century. Originally developed to eliminate glare and direct light downward, this iconic system diffuses light evenly while creating a calm, comfortable glow. The upper metal shade features a rolled edge for both structure and visual weight, while the lower two shades, made from mouth-blown opal glass, ensure a soft and flattering spread of light. The result is a fixture that is both historically faithful and timelessly elegant.

Whether configured as a table or floor lamp, each version of the PH 3½-2½ remains loyal to Henningsen’s original proportions and materials. With finishes in chrome, black, brass or painted metal, these lamps suit both classic and contemporary interiors, ideal for side tables, workspaces, reading corners, or ambient corners of hospitality settings. The brass stem, painted to evoke the burnished finishes of the era, reinforces the lamp’s period character while maintaining modern environmental standards. With its sculptural profile and atmospheric light quality, the PH 3½-2½ remains a lasting piece of Danish design history.
