Black LED ceiling light Rocks with five squares The German manufacturer GROSSMANN has designed the Rocks ceiling light in an unusual, very modern-looking design. It consists of five vertically offset, black cuboids made of brushed aluminium, one of which serves as a ceiling bracket and four as shades. The latter emit the light directly downwards through matt acrylic covers. In addition, a small proportion falls diffusely onto the ceiling, making the cuboids appear to float in the room. The light from the high-quality LEDs presents the room\'s furnishings in their natural colours. Rocks can be dimmed via external phase dimmers. In doing so, the light colour becomes increasingly warmer with decreasing brightness (dim-to-warm).
