Louis Poulsen PH 4/3 Table Lamp

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