The PH 5 was developed by Poul Henningsen (PH) in 1958. The PH 5 was introduced as a novelty, and no one could have known at the time that the PH 5 would eventually become a synonym for the PH lamp. No matter how the lamp is installed and no matter what light source is used, the PH 5 is completely glare-free. The luminaire was named PH 5 because of the 50 cm diameter of the main shade. Poul Henningsen wanted to improve the colour-rendering properties of the light source in the PH 5. Therefore, small red and blue lampshades were added to provide a colour supplement in the part of the spectrum where the eye is least sensitive - red and blue - and thus weaken the light in the middle area - the yellow-green - where the eye is most sensitive. To mark the 50th anniversary of PH 5 in 2008, PH50 was introduced - a version in 5 new high-gloss colours.
The PH5 Classic Pendant Lamp is a designer lamp developed in 1958 by Poul Henningsen for Louis Poulsen. The ultimate glare-free lamp from the unique lampshade system. Developed and conceived in pure raw unadulterated fury at the myriad of light bulbs in a multitude of sizes, the pendant lamp was designed to handle a wide spectrum of light sources.
The PH 5 Pendant Light is designed on the principle of a reflective multi-shade system based on a logarithmic spiral, where the focal point of the light source is located at the centre of the spiral, emitting a diffuse and glare-free light.
