Three-Arm
Floor Luminaire · 1952 Design by Mouille
01 Overview A 1952 Silhouette, Standing Freely
A kinetic, sculptural floor lamp — three independently rotating arms, each ending in a quiet, directional diffuser. Sculpture first, light source second.
The Three-Arm Floor Lamp, designed by Mouille in 1952, is a quietly confident response to what he saw as overly complex contemporary Italian lighting: restraint, geometry, and honest hardware in place of ornament. Three angular steel arms rotate independently from a central pivot, allowing each conical diffuser to be aimed exactly where light is needed. The piece is at once a sculpture, a room-anchor, and a precisely adjustable lighting tool — ideal for expansive rooms, generous reading corners, and gallery-like interiors.
02 Signature Details Five Hallmarks
Detail 01
Independently Rotating Arms
Each of the three arms pivots independently from a central joint — aim each conical diffuser at a different corner of the room, a reading chair, or a display wall. The signature functional feature of the floor lamp over its ceiling sibling.
Detail 02
Arm-to-Diffuser Joint
The precisely machined pivot where each steel arm meets its conical diffuser — a signature connection that defines the lamp's reaching, organic geometry and sets each shade at a controlled angle.
Detail 03
Washer & Hexagonal Screw
Fully visible six-sided screw hardware paired with a washer at every junction — an honest, machined detail borrowed directly from the industrial vocabulary of the 1952 original.
Detail 04
Reflector Form
Elongated conical reflectors deliver soft, directional light while showing a quietly graphic silhouette — functional and sculptural at once, legible from any angle in the room.
Detail 05
Refined Steel & Brass
Slender tubular arms with consistent diameter, anchored by brass ball joints at each pivot. Brass is the piece's only applied warmth against otherwise cool matte-black metal — and will patinate softly with time.

A note on the Three-Head configuration. At Ø 145 cm (57.1″) across and H 210 cm (6 ft 11 in) tall, the Three-Head Floor Lamp is a room-anchoring architectural piece. The arms span nearly five feet in diameter — ensure you have at least 2 m (6.5 ft) of floor clearance on the arm side, and a ceiling of at least 2.4 m (8 ft). Best suited to great rooms, generous living spaces, gallery corners, and loft-scale interiors.
04 Materials & Craft Three Pillars
Lacquered Aluminium
Reflectors and body finished in durable matte black lacquer, giving the piece its graphic silhouette against any interior — a clean, architectural base tone that lets the hardware details speak.
Steel Tubes
Slender, consistent-diameter steel arms carry the electrical and structural load. Refined, unornamented, and allowed to speak purely through geometry — the signature of the design language.
Brass Ball Joints
Warm brass spheres anchor each pivot point — the piece's only applied warmth against otherwise cool matte-black metal. Brass patinates subtly over time, deepening with age.

Indoor use only. Designed for dry interior environments — not suitable for bathrooms, wet rooms, or outdoor installations. The Three-Head configuration requires substantial floor space; please verify room dimensions before ordering.
07 Installation Setup Notes
- Unbox carefully. The lamp ships disassembled in a compact box (L 79 × W 51 × H 32 cm). Follow the included Assembly Instructions for correct orientation — the Three-Head version, in particular, requires care in aligning the arms around the central joint.
- Watch the assembly videos. We recommend watching the Installation video and, for the 3-head version, the 3-Head Assembly video before starting.
- Place the base on a flat, stable surface. Allow clearance behind the lamp for the cord to run cleanly to the wall outlet.
- Install bulbs: 1 bulb for the Single Head, or 3 bulbs for the Three Head (sold separately). Use E26 or E27 base bulbs — a warm white LED (2700K–3000K, 5–8 W) gives the most flattering glow through the reflectors.
- Plug into a standard wall outlet. The 150 cm cord includes an inline on/off switch positioned along the cord.
- Position the arms. Each arm rotates independently at the central pivot. Gently pivot each arm to aim its reflector where you want the light — over a reading chair, across a wall, toward a display. Finger-tighten rather than forcing.
- For the Three-Head version, ensure you have at least 2 m (6.5 ft) of floor clearance on the arm side of the base to allow for full rotation without hitting furniture or walls.
08 Questions Frequently Asked
Do the arms really rotate independently?
Yes — this is the signature functional feature of the floor lamp. Each of the three arms pivots independently at the central joint, so you can aim each conical reflector at a different target in the room. Finger-tighten each arm in its chosen position; forcing a stiff joint can damage the hardware.
Are bulbs included?
No. Bulbs are sold separately. The Single Head takes 1 bulb and the Three Head takes 3 bulbs, both using standard E26 or E27 base. We recommend warm white dimmable LEDs (2700K–3000K, 5–8 W) for the most flattering glow and lowest heat output.
Which should I choose — Single Head or Three Head?
The Single Head (Ø 45 × H 160 cm) is a compact, arm-reaching reading lamp — ideal next to a sofa, armchair, or sitting-room corner. The Three Head (Ø 145 × H 210 cm) is a statement architectural piece — spanning nearly 5 feet across and nearly 7 feet tall, anchoring a great room or gallery. Please check your floor-space and ceiling clearance before choosing the Three Head.
How much space does the Three-Head version need?
Allow a minimum of 2 m (6.5 ft) of clear floor space on the arm side of the base so the arms can rotate freely without hitting furniture. Ceiling should be at least 2.4 m (8 ft) — ideally higher — so the lamp's 2.1 m height reads as a sculpture, not as a column pressed against the ceiling. Best suited to great rooms, open-plan living, gallery corners, and loft-scale interiors.
Is the lamp dimmable?
The lamp itself has a simple inline on/off switch. To dim the light, install dimmable LED bulbs and plug the lamp into a wall outlet controlled by a compatible dimmer switch. The lamp does not have a built-in dimmer.
Can I use it on both 110V and 220V circuits?
Yes. The lamp supports full-range AC 110–240V and is certified for use in North America, Europe, Australia, and the Middle East — no additional transformer required. Just pair it with bulbs rated for your local voltage.
Will the brass ball joints tarnish over time?
The brass joints develop a subtle, natural patina with time — a gentle deepening of tone that many owners prefer as part of the piece's character. To slow patination, wipe the joints with a dry soft cloth; to maintain the original bright finish, a non-abrasive brass polish can be used sparingly. Never use household cleaners on the lacquered arms and diffusers.
Can I place the lamp on carpet or a rug?
Yes, both configurations are designed for use on hard floors or carpet. On deep-pile carpet, place the base on a flat hard protector (a felt pad or a thin sheet of acrylic) if needed to keep the base perfectly level — the Three-Head version in particular is tall and benefits from a stable, level foundation.
Can I install it in a bathroom or outdoors?
No. This lamp is for dry indoor use only. Keep it away from moisture, steam, and direct heat sources — not suitable for bathrooms, wet rooms, covered porches, or any outdoor environment.
How do I clean the lamp?
With the power off, dust the arms, diffusers, and base gently with a soft dry microfiber cloth. For the lacquered surfaces, avoid household cleaners, solvents, and abrasives — they can damage the finish. For the brass joints, a dry soft cloth is sufficient; a mild brass polish can be applied sparingly if a brighter finish is desired.
