Each one is unique - Rusty Square pillar light The design of the Rusty Square pillar light is intended to create a visual reference to classic Japanese garden architecture. This reference is no coincidence, as Japan has a long tradition of cultivating an aesthetic of the ephemeral. And so the unique appearance of the Rusty Square, which changes over the course of its outdoor use, is also reflected in its Japanese design. The Rusty Square lights are extremely stable, made of Cor-Ten steel/cast iron and equipped with energy-saving technology. The special alloy with a high copper content enables controlled rusting on the surface and prevents rust from peeling off. protection class II, IP code IP55 Incl. fixing material
