Spring-Balanced Articulated Arm · Aluminum Body · Plug-In · Three Sizes
A spring-balanced articulated desk lamp built around a multi-joint aluminum arm that pivots, extends, and angles to direct light precisely where you need it. The conical aluminum shade tilts independently at the arm's tip, holding any position via friction joint without re-tightening.
Available in three heights — desk-scale, table-scale, and small-floor-scale — each with a weighted aluminum base and 59" plug cord. Plug-in installation, no electrician required. Suited to home offices, design studios, reading corners, workshops, and any task-light application.

FAQ
Which size suits my use? +
The Desk Scale (35 cm) sits at typical desk-lamp height — fits home offices, study desks, and bedside tables. The Table Scale (50 cm) is for console tables, sideboards, and reading-corner side tables. The Floor Scale (72 cm) is a small-floor task lamp — sits low to the floor for over-armchair reading or beside a sofa.
How does the arm hold position? +
Internal springs counter-balance the arm at every angle — set the arm where you want it and it stays there without re-tightening. The shade also tilts independently at the arm's tip via a friction joint. This is the same articulated mechanism used in classic professional task lamps.
Do I need an electrician? +
No — this is a plug-in lamp. The 59" cord plugs into any standard wall outlet via the inline switch. No hardwiring, no junction box, no electrician needed.
What bulb does it take? +
One E26 (North America) or E27 (EU/UK/AU) standard-base bulb up to 25W. We recommend a warm white (3000K) LED for residential ambiance, or a brighter daylight LED for architectural drawing or precision task work. Bulb not included.
Is it dimmable? +
The lamp itself doesn't dim, but it becomes dimmable when paired with a dimmable LED bulb and a plug-in dimmer module (sold separately). Wall dimmers don't apply to plug-in fixtures.

Mechanical Romance.
Architectural footnotes for the contemporary interior — steel, brass, iron, and the honest marks of the hands that shaped them.

03 — Craft
04 — In Context
From Factory Floor
to Gallery Wall.
The workshops of the early twentieth century were the most honest classrooms industrial design ever had. We take our sense of order from the Bauhaus, our raw material from the foundries of Manchester, and apply contemporary proportion so the result belongs in rooms that reward close attention.
Every fixture we make refuses to hide its structure — visible rivets, exposed cable sheathing, hand-laid joinery. What once belonged on the factory floor now reads as architecture within the room.

Cold-Rolled Steel

Hand-Polished
Forged Iron
Waxed Finish
The weight you feel in your hand is the most honest language of quality — we refuse plastic, refuse thin walls, refuse lightness for its own sake.— Radilum Material Principle N°01
Molten Form
Sand casting runs alongside lost-wax at 1,450°C, leaving each iron piece with the honest mark of its gate.
Hand Welded
TIG welds laid by hand, visible by design. Every welder signs the work with a numbered stamp — traceable back to the piece.
Slow Finish
Hand-polished, aged and waxed across nine stages. We do not chase mirrors — we chase the right matte.
Burn-In Test
A 72-hour electrical burn-in before every fixture leaves the floor.
Modern Farmhouse
A measured dose of grit for soft white interiors — morning light catches on every metal edge.
Minimal Loft
In open-plan rooms it reads less like décor and more like structure — a set of suspended architectural coordinates.
Country Heritage
Lives easily beside reclaimed timber and worn leather — time speaking clearly across different materials.
