Netherlands-based industrial designer Renate Vos created a series of experimental pendant lamps using an unusual combination of concrete and silicone rubber.

Concrete Bin is a self-produced oval light that is a mostly concrete shade with a border of translucent silicone rubber that emits a warm glow.

The Small and Big conic models are produced and distributed by Serax.

Right now, Vos and Serax are also working on an extra-large conic version.
