01Overview
Recycled concrete pendant in four finishes; takes standard bulbs; works with dimmers.
A 10cm cylindrical pendant made from reclaimed ceramic waste—compact enough for tight spaces, bold enough to anchor a corner. The shade diffuses light evenly without glare. Verify your ceiling can handle hardwired installation before ordering.

Is a bulb included?
No. You'll need to buy an E26 or E27 base bulb separately. LED or incandescent both work.
Can I use this with a dimmer?
Yes. It's compatible with standard dimmers as long as your bulb is dimmable (check the package).
Can I make the cable longer?
Standard length is 150cm (59″). Longer cables are available upon request—contact us with your preferred length.
What's the difference between the four colors?
Concrete grey, white, pink, and black are all the same size and price. Choose based on your wall color and décor.
