The louvre is 100% glare-free, with a design based on the principle of a reflective three-shade system, which directs most of the light downwards. The white painted lower surface of the top shade gently directs the light downwards. The two bottom mouth-blown opal glass shades ensure a large glare-free light surface, making optimum use of the light source to provide comfortable, functional lighting. The opal glass shades are shiny on the outside and matt on the inside.
