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.



Caged Glass Tube

Wire safety cage over a colored glass cylinder — industrial bulkhead vocabulary.

Twin-Chain Suspension

Hangs horizontally from two chains — each end mounts to its own ceiling fixing.

Five Glass Colors

Choose silver, black, green, apricot (amber), or clear for the glass tube.


Silver

Mirrored silver glass, reflective.

Black

Smoked black glass, moody.

Green

Forest-green glass, atmospheric.

Apricot

Warm amber glass, vintage glow.

Clear

Clear glass, transparent.


Slim L 123 × W 10 × H 10 cm L 48.4" × W 3.9" × H 3.9" ~18W
Wide L 123 × W 15 × H 10 cm L 48.4" × W 5.9" × H 3.9" ~36W

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.

Customization available on request. The default integrated LED is warm white (3000K) and not compatible with standard wall dimmer switches. If you need dimmable functionality or a different color temperature (4000K neutral, 5000K daylight), please contact us before ordering — custom builds may affect lead time.


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.

The Manifesto
Industrial design earns its charm from honesty. The curl left in a sheet of cold-rolled steel, the heft of solid brass, the sparks caught inside a welded seam — we refuse to hide these marks. They are the evidence that a made object is alive.
Radilum Studio
01 / ORIGIN
A Journey from Factory Floor to Gallery Wall
From factory floor to gallery wall

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.

Measuring for Pendant Lighting

When installing pendants and chandeliers, it’s important to consider how you want your fixtures to hang in relation to the other furnishings in your space. Read on for our recommendations on how to hang the perfect light.

Kitchen

Aim for 30–36″ from the bottom of your fixture’s shade to the top of your island or countertop. Space multiple pendants 26–30″ apart. For a sense of proportion and balance, allow 12″ from the outermost fixture to the edge of your counter.

Dining Room

For optimal lighting and visibility, the bottom of your pendant should sit 30″ from the surface of your dining table. To scale your fixture, take the length and width of the room in feet, then convert that to inches. For a 10′ by 14′ room, the chandelier should be about 24″ wide.

Bedroom

If you’re hanging a pendant above a nightstand, allow for at least 30″ between the bottom of the shade and your nightstand’s surface. To keep the look balanced, center your pendant over your nightstand.
