The PH 3.5 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 handblown 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 matte on the inside.
