Most floor lamps fix their light the moment they leave the factory: the shade points where it points. Moonsetter, designed by Danish architect Anne Boysen for Louis Poulsen, hands that decision back to you with a single turning disc. This piece looks at how the disc works, what the lamp is made of, and what its 45.2 kg base means for the room you put it in.
From competition entry to numbered edition
Moonsetter began as Anne Boysen's winning entry in the Next Danish Design Classic competition in 2020. It was then refined together with Louis Poulsen and released in 2021. It is made in numbered editions of 100, and each piece is engraved with its edition and sequential number.
The idea is stripped back to three elementary shapes. A cylinder forms the base. A slender frame rises from it. Between the arms of the frame sits a circular disc, and that disc is the whole lamp in the sense that matters: it is the only thing that decides where the light goes. There is no shade in the usual sense, no cone, no globe. Seen in a room, it reads first as a small sculpture of chrome and white, and only second as a light.
How the moving disc shapes the light
The disc is solid cast aluminium. One face is chrome-plated, the other is white, and the disc rotates through a full 360° above a concealed LED. The light itself leaves the lamp through an opal silicone diffuser, so you never look into a bare source. What changes as you turn the disc is the character of the light that reaches the room.
- Mirror face forward. The chrome side catches the light and throws it outward. Angle it towards a wall, a ceiling or across the room and you get a brighter, more directed reflection, with crisp highlights on nearby surfaces.
- White face forward. The matte side scatters the light instead of bouncing it. The result is a soft, even glow, close to the lunar quality the name suggests.
- Anywhere in between. Because the rotation is continuous, you can set the disc at any angle, splitting the effect or aiming a reflection at one particular spot.
In practice this means the lamp never has to give the same light twice. In the early evening the mirror can push light into a corner; later, a quarter turn brings the white face round and the room settles. The LED runs at 3500 K, a warm white, and a rotatable switch on the cylinder dims it steplessly, so brightness and direction are both adjusted by hand on the lamp itself rather than on a cord.
Materials and build
Everything you touch on Moonsetter is metal. The frame is high-lustre, chrome-plated solid cast aluminium, and the disc is solid cast aluminium as well. That is why the lamp feels more like a cast object than an assembled one, and why it photographs with such sharp reflections: the chrome mirrors its surroundings, so the lamp changes colour with the room around it.
The practical details are simple. The cord is 2.5 m of black PVC with a separate LED adapter, and the lamp is rated IP20 for indoor use. There is no bulb to choose or replace, which keeps the geometry clean: nothing interrupts the circle of the disc.
What 45.2 kg means in a room
Moonsetter measures 300 mm wide, 600 mm high and 640 mm long, and it weighs 45.2 kg. Those two facts pull in opposite directions. At 600 mm it is a low lamp, about the height of a sofa arm or a side table, yet it is far heavier than a typical floor lamp.
The weight has clear consequences:
- It does not tip. A pet, a child or a passing bag will not knock it over, and turning the disc never rocks the base.
- It does not travel. This is not a lamp you carry from room to room on a whim. Decide where it goes before it arrives, and plan for two people to set it in place.
- The floor matters. On soft wood or delicate stone, a felt pad or a rug under the base is sensible, since 45.2 kg resting on a small footprint concentrates its load.
The comparison with two other Louis Poulsen floor lamps makes the point. The AJ Floor Lamp, Arne Jacobsen's 1957 reading lamp for the SAS Royal Hotel in Copenhagen, stands 1300 mm high and weighs 7.3–8.3 kg. The Panthella Floor Lamp, Verner Panton's design from 1971, measures 500 x 1290 x 500 mm and weighs 12.7 kg. Moonsetter is less than half their height and several times their weight.

Where Moonsetter works best
Moonsetter is a mood lamp rather than a task lamp. Its low height and reflected light suit places where atmosphere counts more than illuminating a page. Three placements make the most of the disc:
- Beside a sofa. At 600 mm it sits at the level of the seating, so the glow stays low and never shines in anyone's eyes.
- In a bedroom corner. With the white face forward and the dimmer turned down, it becomes a gentle evening light.
- Against a pale wall. This is where the mirror side earns its place. Turn it towards the wall and the reflection becomes part of the room.
If you need to read by a floor lamp, pair Moonsetter with something taller rather than asking it to do both jobs. An AJ Floor Lamp beside an armchair handles the page, while Moonsetter sets the mood at the other end of the sofa. Panthella, with its glare-free opal dome, sits between the two: ambient like Moonsetter, but tall enough to light a seating area from above. Our piece on Panthella's single curve explains how its shade and stem work together.
Moonsetter rewards a decision made once and lived with. Choose the spot, set it down, and from then on the only thing you move is the disc. To see it alongside reading lamps and other sculptural pieces, browse the full Floor Lamps collection.
