German designer lighting company GANTlights was established in 2012 by Berlin architect Stefan Gant when he began creating architecturally inspired, minimalist designed luminaries. Highly contrasting materials like raw concrete and gold, silver or copper were joined, resulting in a truly beautiful aesthetic contrast. The products continue to be characterised by their distinctive shapes and unique combination of materials.
