Poul Henningsen developed the PH 5 in 1958 in response to the constant changes made to the shape and size of incandescent bulbs by bulb manufacturers, naming it after the size of the pendant’s main shade, which is 50 centimeters in diameter.

When the lamp was introduced, he wrote, typically daringly, about how he had lost faith that the manufacturers of incandescent light bulbs would ever learn to consider common sense or have the consumer’s best interests at heart. “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!”

Henningsen wanted to improve the color reproduction characteristics of the light source in the PH 5. Therefore, small red and blue shades were inserted to supplement the color in the parts 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.

At the time, no one knew that the PH 5 would become synonymous with the PH light, which remains 100% glare-free, irrespective of how the light is installed or which light source is used.

However, the red and blue rings are no longer necessary to achieve superior light quality because today’s light sources reproduce daylight far better than in Henningsen’s time.

Nonetheless, PH 5 continues to elevate even the most modern interiors in a range of colors today. In 2020, the PH 5 Monochrome series was introduced to emphasize this striking design for a more contemporary look. The matte-painted metal shades come in black, white, and in ultra blue for the bolder decorator.

The fixture provides 100% glare-free light. Its design is based on the principle of a reflective three-shade system that directs most of the light downward. The fixture emits both downward and lateral light, thus illuminating itself.
