Panton's Spiral Pendant: How the Stacked Coils Shape the Light

A Spiral pendant has no shade, no diffuser and no fixed surface for the light to fall on. So what actually shapes its glow, and how long a drop can a room take? This piece looks at how Verner Panton's Spiral lamps are put together, what each part does to the light, and where the long versions belong.

From ceilings of spirals to a single pendant

Verner Panton created the Spiral lamps in 1969, in the most theatrical period of his career. At the time he was designing whole environments rather than individual objects: the Visiona installations and the interiors for the Spiegel publishing house in Hamburg, where ceilings hung with shimmering spirals made the boundary between lighting and architecture hard to locate. Air currents and footsteps set those ceilings in gentle motion, so the room never looked the same twice.

The pendants that VERPAN of Denmark keeps in production today condense that idea into a fixture you can hang from one ceiling point. The principle has not changed. Instead of a shade that blocks and redirects light, the lamp is a cluster of thin coils, each one catching the light source at a slightly different angle and throwing a small reflection back into the room. The collection description calls it Panton's play with colour and form: how an object interacts with its surroundings through reflection, sound and movement.

How the Spiral is built, part by part

Strip the lamp back and there are four elements. The spirals themselves are cast ABS plastic, a stiff, light material that holds the coiled form and takes a mirror-like silver or gold finish. The coils are held in formation and suspended below the ceiling fitting, and the whole assembly hangs from a transparent plastic cord, chosen so the cable almost disappears and the cluster seems to float.

The details differ between models, and they are worth knowing before you choose:

• Spiral Pendant and Spiral Pendant Mini: cast ABS spirals on stainless steel rings, with a chrome-plated metal canopy.
• Spiral Pendant SP1 and Spiral Pendant SP2: cast ABS spirals on nylon string, with a ceiling canopy also cast in ABS plastic.

All four use the transparent cord. The steel-ring versions have a crisper, more mechanical structure at the top; the nylon-strung versions let the coils hang a little more freely. Either way, what you see from across the room is not the construction but the sparkle.

Why stacked spirals filter light the way they do

A conventional pendant controls light by blocking it: an opaque shade hides the bulb and sends light down, and anything that escapes sideways is a by-product. The Spiral works the other way round. Because the coils reflect rather than glow, the light source is broken up into hundreds of small highlights, each one a slightly different angle of the same bulb. Look from below and you see glitter; look from the side and you see a soft, shifting column of silver or gold.

Stacking makes the effect deeper. In the cascading models, the upper coils catch the light first and hand part of it down to the lower ones, so the reflections travel the length of the lamp rather than stopping at a single rim. On the SP2, which stacks two generous clusters into one vertical composition, the upper crown lights the lower one and the pendant reads as a continuous column with the presence of a chandelier, without a single crystal.

Two further effects come from the material. The spirals are light enough to turn slightly as air moves through the room, so the pattern of highlights is never fixed. And because the finish is reflective, the lamp keeps working when it is switched off: hung near a window, the coils pick up daylight and read as bright silver or warm gold through the day.

Sizes, drops and weights compared

The family ranges from a compact cluster to a column more than two metres long. Dimensions below are as VERPAN gives them.

The weights matter as much as the lengths. At 14 kg for the SP2 and 17 kg for the SP3, the long versions need a ceiling fixing that is rated for the load, and it is sensible to have an electrician confirm the anchor point before installation. Even the Mini, at 5 kg, is heavier than it looks, because the effect relies on a dense mass of coils.

Where a 180 cm or 220 cm drop belongs

A pendant close to two metres long only makes sense where there is real vertical space to fill. The natural home is a stairwell. Hung in the open void between flights, an SP2 or SP3 is seen from every level: from below as a glittering underside, from the landing at eye height as a column of reflections, and from above as a crown. People move past it constantly, which keeps the air, and the coils, in motion.

A double-height entrance hall works for the same reason. So does a tall living space with a gallery, or a stair window where daylight reaches the spirals for part of the day. In each case, leave clear air around the lamp. It is a sculpture as much as a light, and it needs to be seen from several angles to make sense.

Avoid the long versions under a standard ceiling height, even over a dining table. There the drop would bring the lower coils down into the line of sight or the path of a head. For a table, the 65 cm Spiral Pendant or SP1 is the right scale; the collection's general guide of roughly 60–70 cm between tabletop and lamp still applies, measured to the bottom of the cluster.

Silver or gold, and living with the Spiral

The Spiral Pendant, SP1 and SP2 each come in silver or gold, and the product descriptions note that mixed silver and gold finishes let cool and warm reflections mingle across the cascade. Silver sits comfortably with white walls, steel and glass, and reads almost like cold light. Gold warms a room with timber, brass or darker walls, and flatters faces at a dinner table. The Mini is offered in silver.

In daily use the Spiral is a soft, glittering source rather than a task light. Pair it with a focused lamp where you read or cook. Its reward is atmosphere: a moving, living point of light that makes a stair or a hall feel inhabited.
