Two big realities in lighting consulting and sales which enpowered Illum's strenght and structure throught both Italian and worldwide market. Illum’s real strength lies in its members: architects and engineers with specific training in lighting technique design with thirty years of experience in the trade. Lighting design’s development occurs in accordance and collaboration with architects and engineers who design both the outer structure and interior design. As a result, electrical installations are processed and produced as a result of our designs created by professionals in the trade. We thus offer solutions that are absolutely innovative and, in particular situations, our lighting technique designs give rise to new lighting systems that will enter and form part of our client’s coordinated image. Illum is a company that not only deals with light: in 2019 a new division raised. Adele Interiors, based in Florence, is the Illum groups's responsible for all the interior design.
