The indirect light creates a gradual transition to the darker ceiling; while the direct light casts its focus right below. In order to utilise the luminaire’s inner space, the lower long side is perforated. The light forces its way through as small elements and illuminates the whole of the inner space. Depending on the chosen louvre, graphic patterns are created with different brightness. A further contrast is the body which emphasizes the design – the open and the enclosed. The strength of the contrast is determined by the colour of Open Box: grey or black.
