For a successful presentation of architecture: the series of wall lamps Artemide Architectural Effetto unites a large number of minimalist objects, which are whether round or cubic, and produce broad or narrow light beams. The here presented light version has a round structure and produces a broad and a narrow light beam from two opposite sides. The light of a monochromatic LED lodged in the box passes through the lenses of the diffuser of synthetic material PMMA, which has been made water-proof with the aid of silicone. The wall plate to affix to the house wall is made of reinforced synthetic material, the screws are made of stainless steel. In this way, the light fixture meets the requirements for the IP65 classification and is therefore suitable for outside. There are alternative objects with 2 broad, or 2 narrow light beams, with 1 or even 4 apertures for the passage of the light, which are all presented under the heading "product family".
