Wohlert Pendant: An Opal Globe from Louisiana's Co-Architect

The Wohlert Pendant is about as plain as a pendant can be: one white glass globe on a short steel collar. This piece looks at who designed it, what the glass and fitting actually do, which of the three sizes suits which room, and how it compares with the smaller Toldbod Glass Pendant.

An architect's lamp from 1959

Vilhelm Wohlert was a Danish architect, best known as co-architect, with Jørgen Bo, of the Louisiana Museum of Modern Art north of Copenhagen, which opened in 1958. A year later, in 1959, he designed this pendant for Louis Poulsen. It shares the calm of that building: low-key, carefully proportioned and happy to let the surroundings take the attention.

The late 1950s were a busy time for Danish lighting. Poul Henningsen was refining multi-shade systems that hid the bulb behind layers of curved metal, and Louis Poulsen launched the PH 5 in 1958. Wohlert went the other way. Instead of building a shade from several parts, he reduced the lamp to a single rounded globe that glows evenly in every direction. It is an architect's answer to a lighting problem: make the object quiet, and let the light describe the room.

Opal glass, a steel collar and an open base

The globe is mouth-blown in matt white opal glass. Opal glass is milky rather than clear, so the bulb disappears and the whole surface becomes the light source. The matt finish takes this a step further: there is no glossy highlight on the outside, only an even, moon-like glow. From across a room the lamp looks less like a fitting and more like a pale sphere floating in the air.

At the top, the glass meets a pendant fitting in brushed steel. This collar is small in relation to the globe, and its brushed finish keeps it from flashing or competing with the glass. It is the only metal you see, and it gives the lamp a precise, engineered edge where it could otherwise look soft.

At the bottom, the globe has an opening. This matters more than it seems. It lets a portion of the light fall straight down onto a table, a counter or a floor, so the Wohlert is not only an ambient glow but also a useful task light below it. It also means the bulb can be changed from underneath without taking the lamp apart.

The Wohlert Pendant comes with a 3 m white fabric cord and a canopy. It takes one E27 bulb, max 70 W, and is also available in LED versions (Dim-to-Warm, 41 W, 3000–1800K) that are phase dimmable with standard dimmers. On the LED versions the cord is 4 m and the driver sits in the canopy. The bulb is not included, and the lamp is rated IP20 for indoor use.

Three sizes, and what the numbers mean in a room

The Wohlert Pendant is made in three diameters. These are the measurements Louis Poulsen gives:

• Ø 300: 300 x 320 x 300 mm, 6.4 kg.
• Ø 350: 350 x 370 x 350 mm, 7.8 kg (LED: 10.6 kg).
• Ø 400: 400 x 420 x 400 mm, 7.8 kg (LED: 10.6 kg).

Two things stand out. First, each globe is slightly taller than it is wide, because the steel collar sits on top of the sphere. Second, these are heavy lamps for their size. Mouth-blown opal glass is thick, and even the smallest globe weighs 6.4 kg. Before you hang one, check that the ceiling point is rated for the weight, especially for the LED versions of the two larger sizes.

As a rough guide, the Ø 300 suits bedside use, a small dining table or a narrow hallway. The Ø 350 is the all-rounder: large enough to hold its own over a dining table for four, small enough for a kitchen island run. The Ø 400 has real presence and suits a larger table, a stairwell or a double-height space where a smaller globe would look lost.

Where the Wohlert works: stairwell, kitchen island, bedside

Stairwell. A stairwell is seen from above, from below and from the side, and the Wohlert looks the same from every angle. Because the globe glows all round, it lights the walls and the treads rather than creating a single bright pool. A Ø 400 hung in the open well of a staircase, or two or three smaller globes at staggered heights, give the space a focal point that works from every landing.

Kitchen island. Two or three globes in a line along an island or counter create a gentle rhythm. The open base throws direct light onto the worktop, while the glass fills the kitchen with soft general light. The Ø 300 and Ø 350 are the usual choices here; keep equal spacing between the globes and align them with the centre line of the island.

Bedside. Hanging a Ø 300 low beside the bed, in place of a table lamp, frees the bedside surface entirely. The diffused glow is kind to the eyes at night, and the downward light from the base is enough to read by. The LED versions, with their Dim-to-Warm range down to 1800K, suit this use especially well, as the light grows warmer as it dims.

Wohlert or Toldbod Glass Pendant?

Louis Poulsen's Toldbod Glass Pendant is the natural alternative. Launched in 2002 and named after the Toldbod quarter on Copenhagen's waterfront, it is also mouth-blown opal glass with a brushed stainless steel fitting. The difference is in shape and scale. The Toldbod's shade is mouth-blown in three layers, glossy on the outside, and its reflector geometry, drawn from Poul Henningsen's PH Ellipse studies, directs a comfortable cone of light downward. It is a smaller, lighter lamp that puts more emphasis on the surface beneath it.

Choose the Wohlert when you want the lamp to fill a space with even, all-round light and to register as a clear form in the room. Choose the Toldbod when space is tight or you want several small lights in a row: a Ø 155 weighs 1.8 kg against the Wohlert Ø 300's 6.4 kg, and lines up neatly over a narrow counter. For a warmer, more reflective contrast in metal rather than glass, Vilhelm Lauritzen's VL 56 Pendant directs its light downward from a small polished shade and pairs well with either.

Living with a white globe

The Wohlert's appeal is that it asks very little. The matt opal glass hides the bulb, so there is no glare to manage and no angle from which it looks wrong. It sits comfortably in a plain white room, against timber or brick, and among older furniture. Its plainness is the point: it does one job, even and gentle light, without drawing attention to itself.

Keep the glass free of dust with a soft, dry cloth, and wipe it with a slightly damp cloth when needed, making sure the lamp is switched off and cool.
