Moon Pendant: Panton's Adjustable Lamella Shade

Most pendants give you one decision to make: which shade, which size, which colour. Verner Panton's Moon asks for a second one after it is hung, because its rings move. This piece looks at how the adjustable lamellae work, how the two metal sizes differ, and when the fixed Moon Opal is the better choice.

A young architect breaks the shade apart

Panton trained as an architect at the Royal Danish Academy of Fine Arts in Copenhagen and worked in Arne Jacobsen's studio in the early 1950s before setting up on his own in 1955. The Moon followed in 1960, part of his first wave of independent lighting. Danish lighting at the time was dominated by the refined single or layered shade, where the designer fixed the geometry once and the lamp did the same thing forever.

Panton went the other way. He took the shade apart into ten concentric rings, graduated in size and hung in a fan formation around the bulb. Seen straight on, the rings close into a sphere. Seen from the side, they open into a stack of thin crescents. The bulb stays hidden from every normal viewing angle, while light escapes in the gaps between the rings. It is an early sign of the experimental streak that later produced the Panthella lamp, the FlowerPot and the Panton Chair. Today the Moon is produced by VERPAN, the Danish company that manufactures Panton's designs to his originals.

How the movable lamellae shape the light

On the Moon Pendant the lamellae are not locked in place. Each ring can be turned on the central axis, so the owner decides how far the fan opens. Close the rings up and the lamp reads as a near-solid white ball: little light leaks sideways, most of it spills down and up through the openings at the poles, and the room around it stays calm. Fan the rings out and every gap widens, so more light escapes to the sides and the walls pick up soft bands of brightness.

That is the practical point of the design. A pendant over a dining table wants its light concentrated on the tabletop and should not glare at the people sitting around it. A pendant in a hallway or a double-height room can afford to throw light outwards and wash the surrounding surfaces. With the Moon, the same fixture can do either, and you can change your mind later without changing the lamp.

Because the rings are lacquered metal, they are opaque. Light never passes through them; it only reflects off their white inner faces and slips out between them. That gives the metal Moon a crisp, graphic quality, with clear lines of light and shadow, rather than a uniform glow.

Small or large: sizes and weight

The metal Moon comes in two sizes, and in both the diameter and height are equal, which is why it reads as a sphere when the rings are closed. The lamellae and canopy are lacquered metal, and the cord length is 250 cm.

• Small: Ø34 cm, H 34 cm, 4.5 kg.
• Large: Ø44.5 cm, H 44.5 cm, 8 kg.

The small size suits a round table for four, a bedroom or a hallway with an ordinary ceiling height. The large size holds its own in open-plan living spaces, above a longer dining table, or in a stairwell where it is seen from below and from the side. At 8 kg, the large version is a substantial fixture, so make sure the ceiling point is solid before it goes up. Over a dining table, a starting point of roughly 60–70 cm between the bottom of the shade and the tabletop keeps the surface lit without blocking the view across the table.

Moon Opal: the fixed, softer version

The Moon Opal Pendant keeps the same ten-ring silhouette but changes its character. The lamellae are made of opal matt acrylic, the canopy is white painted metal, and the rings are fixed rather than adjustable. It comes in a single size, Ø34 cm, and weighs just 1.9 kg, a fraction of the metal small version.

The material makes the difference. Where metal rings block light and only let it out through the gaps, translucent acrylic glows. Light is diffused twice, once through the rings themselves and once between them, so the whole lamp becomes luminous. The result is gentler and more even, with less contrast between ring and gap. You give up the ability to tune the sideways spill, but you gain a lamp that needs no tuning at all.

Living with a Moon

The Moon behaves like kinetic sculpture. Walk around it and the outline shifts from a sphere to a layered fan and back. That makes placement more important than with a conventional shade: it is at its best where it can be seen from several sides, above a dining table, in the middle of a hallway, or in front of a window where daylight catches the rings during the day.

Choose the metal version if you like to adjust light by season or occasion, closing the rings for a quiet dinner and opening them when the room needs more ambient light. Choose the Opal if you want the silhouette with the softest possible light and a lighter fixture overhead. In both, the bulb stays out of sight, which is why the Moon works well in rooms where people sit for a long time.

If you like Panton's idea of hiding the source and letting reflected light do the work, the VP Globe Pendant Ø40 from 1969 takes it in a different direction, with aluminium reflectors suspended inside a clear acrylic sphere. Our piece on the VP Globe's sphere of reflected light covers that design in detail.
