Product Description

The PH 5 & PH 50 pendant lights provide 100% glare-free light from above. The design is based on the principle of a reflective three-shade system, which directs majority of the light downwards. The fixture emits both downward and lateral light, thus illuminating itself. In the PH 5 Classic, a warmer tone of light is created by the inside red cone and a small blue reflector.

  • glare free light
  • symmetric light distribution
  • suitable for high and low mounting
  • the fixture illuminates itself and its surroundings
  • suitable for repetitive installations
  • belongs to a family which includes floor and table models

Poul Henningsen developed the PH 5 in 1958 in response to constant changes to the shape and size of incandescent bulbs by bulb manufacturers. At the introduction of the PH 5, Poul Henningsen wrote the following: “After 33 years of basically Christian behaviour I have converted to Islam in my relationship to the manufacture of incandescent bulbs. For a generation I have believed that consideration for the consumer and common sense would prevail, but now I have become a fatalist. I have accepted fate, and with Louis Poulsen´s permission I have designed a PH fixture which can be used with any kind of light source, Christmas lights and 100 W metal-filament bulbs. Although a fluorescent tube would be too much to ask in the existing form!”.

The PH 5 was introduced as a classic new product, and no one knew at the time that it would eventually become synonymous with the PH light. Irrespective of how the light is installed or the light source used, the PH 5 is and remains completely glare-free. The pendant light was christened PH 5 due to the 50 cm diameter of the main shade. Poul Henningsen wanted to improve the colour reproduction characteristics of the light source in the PH 5. Small red and blue shades were therefore inserted to supplement the colour in the part of the spectrum where the eye is least sensitive – the red and blue areas – thereby subduing the light in the middle yellow-green region where the eye is most sensitive. The PH 5 design has been regularly updated as light sources have developed. The PH 5 plus, designed for use with energy-saving bulbs, was introduced in 1994. To achieve higher efficiency, the metal plate was replaced with frosted glass and the light was painted using a purer white colour.
