Caged Glass Tube · Twin-Chain Suspension · Industrial Bulkhead
A horizontal tube pendant in industrial bulkhead vocabulary — a colored glass cylinder enclosed in a wire safety cage, suspended from twin chains at either end. Equally at home over a dining table, kitchen island, long bar, or workshop bench, where its linear silhouette stretches across the whole length of the surface below.
The integrated LED runs the full 123 cm length of the tube — when lit, the colored glass and wire cage cast a layered pattern of warm light and shadow across the surface. Available in five glass colors and two power configurations.

Sizes — Choose at Checkout
Slim vs. Wide — same length, different output. Both sizes are identical in length (123 cm / 48.4") and hanging chain (70.9"). The Wide version is larger in cross-section (15 × 10 cm vs. 10 × 10 cm) and produces twice the light output (~36W vs. ~18W) — better for larger dining tables, kitchen islands, or high-ceiling spaces. The Slim version suits standard residential installations.

FAQ
Which size should I choose? +
Both sizes are 123 cm long. The Slim (10 × 10 cm cross-section, ~18W) suits standard 4–6 person dining tables, kitchen counters, and bedrooms. The Wide (15 × 10 cm, ~36W) doubles the light output — better for larger 8-person tables, full kitchen islands, long bars, or rooms with high ceilings where more light is needed.
Do I need two junction boxes? +
Yes — the pendant hangs from two separate chains, one at each end. Each chain requires its own ceiling fixing point and the wiring runs through one of them. A licensed electrician can confirm the spacing and wiring requirements based on your ceiling.
Is it dimmable? +
The default integrated LED is not dimmable — it will not work with standard TRIAC wall dimmers. If dimming matters for your installation, please contact us before ordering and we can supply a dimmable version (custom build, may affect lead time).
Can I get a different color temperature? +
The standard version ships in warm white (3000K), ideal for residential dining and living. If you need neutral white (4000K) for kitchens or daylight (5000K) for workshops, please contact us before ordering — custom CT options are available on request.

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

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.

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.
