PH 3½-2½ Table Lamp

The PH 3½–2½ Glass Table Lamp was designed in 1928. It is one of many progressive projects Poul Henningsen developed alongside his famous three-shade system from 1926. Henningsen dedicated much of his life to mastering electric light. His three-shade design is based on a lituus curve, allowing the light source to be used with maximum efficiency. Throughout his work, he conducted continuous calculations and experiments — the shape of each shade was determined by how it should direct and reflect light.

For Henningsen, glare-free illumination was essential. The first PH table lamp was completed in early 1927 and introduced as an alternative to low-hanging pendant lights. The white opal glass shade gives the lamp a soft, elegant appearance while illuminating its surroundings with perfectly balanced, glare-free light — a quality only the three-shade system can provide.

The mouth-blown, three-layered opal glass is glossy on top and matte sandblasted underneath, creating exceptionally gentle and even light diffusion.
