The PH 5 Mini, with a diameter of 30 cm, is a scaled down version of the iconic PH 5 (50 cm in diameter). Poul Henningsen developed the PH 5 in 1958 in response to constant changes to the shape and size of incandescent bulbs by bulb manufacturers. 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 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. Like the PH 5, the PH 5 Mini is available in the classic white version, a modern white model and in six colour versions, where the colour is darkest at the top and gradually lightens moving down from shade to shade. The struts are purple on the classic model and bronze-coloured on the other seven versions. The reflector ring colour contrasts with the other hues. To celebrate the 60th anniversary in 2018 of this beloved pendant, Louis Poulsen released the PH 5 and PH 5 Mini in an edition that pairs copper shades and white tiers and in 2019 with brass shades. The new metallic-and-white combination highlights Henningsens shade system design and adds new dynamism to one of his most recognised forms, with the mirror-like metal tiers reflecting their surroundings. The metal shades a untreated and will patinate over time.
