PH 3.5-2.5 Floor Lamp

The floor lamp provides a soft, harmonious and comfortable light distribution with its mouth-blown three-layer white opal glass that primarily directs the light downwards. Poul Henningsen designed it based on his celebrated three-shade system, which he created in 1925 to shape excellent non-glare lighting.

The first lamp using the multi-shade system was made in collaboration with Louis Poulsen for the Paris exhibition that same year. The ‘Paris Lamp’ won gold.

Henningsen had a distinct scientific approach to light and continued to design numerous luminaires based on the same system. He used the logarithmic spiral as the foundation and accomplished even distribution of light with the three-shade-system, which together with a dispersed reflection through the glass made it possible to curb glare and shadow.

Each PH lamp number refers to the size of its shades. The PH 3½ - 2½ Floor consists of a top shade of approximately 35 cm with lower shades from the 2½ version. PH 3½-2½ Floor in its current form was introduced in 2002.

The fixture is designed based on the principle of a reflective three-shade system, which directs the majority of the light downwards. The shades are made of handblown opal three-layer glass, which is glossy on top and sandblasted matte on the underside, giving a soft and diffused light distribution.
