Designed by Danish visionary Poul Henningsen and manufactured by Louis Poulsen, the PH series of lamps have withstood the test of time with their elegant design

Peep through the windows of Copenhagen apartments and restaurants, and you’d be able to spot at least one Poul Henningsen-designed pendant lamp hanging from the ceiling. A renowned Danish architect, designer and author, Henningsen—who often went by his acronym PH—is often celebrated as one of the leading figures in Danish modern designs. 

It’s interesting that the design pioneer, renowned for his innovative lighting designs, grew up in an era without electric lighting. Born in a small Danish town in 1894, Henningsen’s world was lit up by gas lamps. As he grew older, however, electricity soon became more widespread during the turn of the century.

Today, the lamps continue to be Louis Poulsen’s most successful designs. In Singapore, the lamps retail at Grafunkt and Xtra.

Gas lamps were replaced by incandescent bulbs, which became the standardised form of lighting in the streets, homes, and stores. Henningsen was notably displeased with the design shift, calling the new bulbs “muffins” and noting that the purpose they served was more utilitarian rather than aesthetic. 

The designer was soon inspired to create one of his greatest designs—the three-shade lamp series—after his mother complained about the harsh, unflattering light of the new bulbs. Henningsen desired to create a lamp system that infuses an interior with 100 percent glare-free illumination.

To achieve this, he designed separate aluminium shades that surrounded the light bulb. These shades were intentionally curved to help disperse the emitting glow in different directions to fully illuminate a space rather than shining directly into people’s eyes. 

In order to neutralise the unflattering yellow glare from the incandescent bulb, Henningsen hid anti-glare rings and reflectors within the heart of the lamp. This clever system offers a warm, natural feel and reduces the harshness of the bulbs.

The designer officially launched the lighting system in 1926 as a series of lamps with Danish lighting manufacturer Louis Poulsen, a company with which Henningsen would build a lifelong working relationship eventually. From then on, the rest is, as they say, history. The lamps quickly garnered popularity for their ability to distribute light evenly for a soft, ambient glow. The beautiful sculptural lamp shade was an additional plus point. Offering both form and function, the minimalist form suits a variety of decor styles and lends a modern expression to any room.

In 1958, Henningsen updated the series with a new development: the five-shade system. Commonly known as the PH 5 series of lamps, it was designed as a response to the constant changes made to the shape and size of incandescent bulbs by bulb manufacturers and is based on similar principles as its predecessor. 

The PH 5 quickly grew to become synonymous with what the public will come to know as ‘the PH light’. The lamps are a constant favourite and can be spotted within the homes of stylish tastemakers like Korean model Jang Yoon-ju, or on film sets such as James Bond’s Quantum of Solace.

In 2017, Louis Poulsen released the new PH 5 Mini—the first-ever resize of the original lamp—in various colour combinations. In 2018, to mark the sixtieth anniversary of the timeless icon, the lighting manufacturer released the original pendant lighting in a similar suite of vibrant colour combinations. 

With their contemporary composition and glare-free glow, the PH lamps imbue a chic, timeless appeal to interiors. As Henningsen once said, “once you have experienced real lighting, life is filled with new values”.
