The fixture is designed based on the principle of a reflective three-shade system, which directs the light downwards. The shades of the PH 4/3 table lamp are made of metal and painted white to ensure diffuse, comfortable light distribution.

Poul Henningsen designed the three-shade system back in 1925-1926. The first lights using the system were designed by PH in cooperation with Louis Poulsen for an exhibition in Paris. This partnership continued up until his death in 1967. Throughout his life, PH sought to create glare-free light, direct light where it was most needed, and create soft shadows, using incandescent bulbs as a light source. PH was the first person to pursue a scientific approach to light and use the logarithmic spiral as a basis. By using a design based on the logarithmic spiral he achieved even distribution of light over the entire curve of the shade.

The PH light model numbers refer to the shade size. PH 4/3 Table consists of an approximately 40 cm top shade, but uses lower shades from the 3/3 model. These ‘hybrid’ models were introduced due to the desire to hang pendants at lower heights. The system was also used for wall, table and floor lamps. PH 4/3 Table in its current form was introduced in 1966.
