[H2] About this product

Poul Henningsen endeavoured to create glare-free light, direct light where it was most needed, and create soft shadows, using incandescent bulbs as a light source. Henningsen’s mathematic approach to lighting, using the logarithmic spiral, led to the development of the System PH in 1926, which over the years has included hundreds of different models, ranging from floor lamps to table lamps, pendants, chandeliers, and wall lamps.
The PH 1/1 Portable Lamp is a cordless version of the classic table lamp. The PH 1/1 is the smallest shade set of the System PH and is described as a “whole” sized lamp, characterised by its appealing compact semblance with a top shade of approximately 10 cm, corresponding to the middle and lower shade in the proportions 3:2:1. PH’s “whole” sized lamps are designed to be particularly glare-free, and they are therefore ideally placed high in a room where they integrate high-quality lighting with a warm ambience.
The PH 1/1 Portable Lamp can be used for both indoors and outdoors, particularly in spots where there may not be easy access to mains electricity, such as inside a bookcase or on a table.

[H2] Discover the PH 1/1 portable lamp
The PH 1/1 Portable Lamp is a compact interpretation of Poul Henningsen’s three-shade system, designed to provide soft, glare-free light in a cordless format. Based on the original principles developed in 1926, the layered mouth-blown opal glass shades diffuse light evenly, creating a calm and balanced atmosphere.
Scaled down in size, the lamp is designed for flexible placement across the home and beyond.

[H2] About this product

Danish writer, designer, and architect Poul Henningsen (1894-1967) had a vision – to capture the golden hour. In 1958, he created the PH 5 in response to incandescent bulbs and the constant changes in their shape and size and the consequent risk of glare – something PH wanted to avoid. The result was a striking and versatile lamp that could accommodate any bulb. This soon became the PH lamp in Denmark, used in public buildings and private homes.
Known as the PH lamp, the iconic PH 5 design is based on Henningsen’s renowned three-shade system. The pyramid-like fixture effuses both descending and lateral light to illuminate itself. This ensures the light is soft, rich, and completely glare-free. The PH 5 initially incorporated shades in red and blue to improve the light’s color. However, in the latter designs, these were taken out as modern light sources replicate daylight more successfully than before. The classic PH 5 lamp remains a design favorite today, with several styles, hues, and shapes bringing characteristic lighting to any living space.
A pendant of notable design, the PH 5 is a much-loved and well-known lamp found in many homes worldwide. Different hues offer a dynamic gradient effect, making it the perfect addition to your dining room, hallway, or kitchen. Elevate your home with the PH 5 pendant from one of Louis Poulsen’s most credited designers. A design that transcends time and place – that’s what makes the PH 5 an icon.
