Modular desk lamp · 5 parts
Strut
Five parts, one hex key, no glue. A sprung architect’s lamp you can rebuild, repair and refinish instead of replace.
- Ships in 3–5 working days
- 5-year warranty on every module
- 30-day returns
† Sample values. Strut is a concept product; price, delivery, warranty and specifications on this page are illustrative.
Built from five parts.
Every joint is the same 4 mm bolt and friction knob. If one part breaks or you want a new finish, swap that part and keep the rest.
Base
Weighted cast-iron disc with a rubber foot. Holds the dimmer and the cable exit.
Riser
Swivel turret and shoulder joint. Turns the whole arm around the base.
Lower arm
Twin steel rods with a balance spring, so the arm holds any angle.
Upper arm
Second rod pair and spring, with the elbow joint the cable loops around.
Head
Spun shade with a recessed diffuser. The LED and its driver live here.
Light, exactly where you need it.
Point the head, set the warmth, and the light stays on your page instead of in your eyes.
Tunable white. Candle-warm for evenings, daylight-cool for detailed work.
True colour. Paper, paint and fabric look the way they will in daylight.
Recessed diffuser. The LED sits back inside the shade, so you see light, not glare.
Stepless dimmer. One knob on the base, from a glow to full task light.

Questions
What do I need to put it together?
Only the 4 mm hex key in the box. Each module bolts to the next through its joint, and the cable clips along the arms.
Will the head stay where I leave it?
Yes. Two balance springs carry the weight of the arms, and the friction knob on each joint sets how stiff it feels.
What happens if the LED fails?
The LED and its driver live in the head. Replace the head module and keep the base and arms.
Can I change the finish later?
Each module comes in all three finishes, so you can swap a single part or all five.
Why do I see a “Lite” viewer instead of 3D?
On older phones, with data saver on, or in browsers without WebGL, the page shows a lighter turntable made of still images so it stays fast. You can still turn the lamp, change the finish and switch the light on. Where 3D is possible, the “3D” button above the viewer loads it.
