AJ lamp: Arne Jacobsen’s light for a modern hotel
Drawn in 1957 for the SAS Royal Hotel in Copenhagen, Arne Jacobsen’s AJ lamp reduced a reading light to a stem, a slanted shade and a base, and Louis Poulsen has made it ever since.
Most lamps are designed for a room. The AJ lamp was designed for a whole building. Arne Jacobsen drew it in 1957 while he was working on the SAS Royal Hotel in Copenhagen, and when the hotel opened in 1960 the lamp was everywhere: on the walls of the entrance, in the work areas and on the desks of the guest rooms. Louis Poulsen has produced it continuously since the late 1950s.
A hotel designed down to the cutlery
The commission came from Scandinavian Airlines. SAS wanted more than a luxury hotel: the building in central Copenhagen was also to serve as an air terminal where travellers could check in for their flights. When it opened, it was the tallest building in Denmark, a title it held until 1969.
Jacobsen designed far more than the tower. He worked on the interiors, the furniture, the lighting and even the cutlery, treating the hotel as a , the German term for a total work of art in which every part serves one idea. The Egg and the Swan chairs were created for the same project. The hotel is often called the world’s first design hotel, and although later renovations removed most of the original interior, Room 606 has been kept as Jacobsen conceived it.
Straight lines and oblique angles
The AJ lamp did not come from nowhere. Jacobsen had explored a similar figure in earlier lamps, such as the Bellevue lamp of 1929 and a table lamp for Søllerød Town Hall in 1942. For the SAS project he reduced it further, to straight lines and oblique angles: a thin stem, a base and an asymmetric shade cut at a slant.
That slanted shade is the point of the design. It hides the bulb from anyone sitting nearby and throws the light downwards and to one side, onto a desk, a book or the arm of a sofa. The head can be tilted, so you can direct the beam more precisely. In a hotel full of curves, from the Egg to the Swan, the AJ lamp supplied the counterpoint: crisp, linear and quietly technical.
Look at the base of the table lamp and you will find a round hole. It lightens the look of the base, and the story most often told is that it was originally meant to hold an ashtray, a reminder of how different hotel rooms were in 1960.
Table, floor and wall
Jacobsen created three versions, and all three have stayed in production:
- Table lamp: the guest room desk lamp, with the round cut-out in its base.
- Floor lamp: the same slanted shade on a tall stem, made for reading beside a lounge chair or sofa.
- Wall lamp: used at the hotel’s entrance and in its work areas, and today a favourite for reading beside the bed.
Louis Poulsen has since added a smaller AJ Mini table lamp. The lamps are made of steel and zinc and are offered in a range of lacquered colours, so the same outline can read as discreet in white or as a graphic accent in a strong colour.
The SAS Royal Hotel was not the only early home of the lamp. Jacobsen used it in the house he furnished for the Interbau exhibition in Berlin in 1957, at the SAS air terminal that opened in 1959, at St Catherine’s College in Oxford from 1964 and at Rødovre Library in 1969.
The idea of total design
Why does a lamp designed for a hotel still make sense in a private home? Partly because Jacobsen designed it as a tool. It solves one problem, light where you need it without , and it does so with very few parts. Glare is the harsh, uncomfortable brightness you feel when a bare bulb or a very bright surface sits in your field of view.
It solves one problem, light where you need it without glare, and it does so with very few parts.
It also carries the logic of total design into a smaller space. In Jacobsen’s hotel every object answered to the same set of lines and proportions. At home you can borrow that discipline on a modest scale: choose a few pieces that share a language and let the lighting follow it. An AJ floor lamp beside a lounge chair with a similarly slender profile shows how much calmer a room becomes when the objects agree with each other.
Living with an AJ lamp today
The floor lamp is the natural reading companion. Place it beside or slightly behind your chair, with the shade angled so the light falls onto the page and not into your eyes. The table lamp works on a desk or on a console in a hallway, and the wall lamp is excellent beside a bed or above a narrow desk where floor space is limited.
For reading, choose a warm white bulb of about 2,700 to 3,000 (K) with a good . CRI, the colour rendering index, describes how faithfully a light shows colours on a scale up to 100. A value of 90 or more keeps book covers, fabrics and skin looking natural.
More than sixty years on, the AJ lamp still does exactly what it did in 1960: it lights a small area well and looks composed while doing it. That modest ambition is the reason it has outlived so many louder designs.
