In the lighting design of the Roozan Residential Complex, the focus was on creating harmony between indoor and outdoor spaces. Interior designers employed the latest lighting techniques to create a cozy and functional environment for the residents. Dark Light fixtures were installed in the living area to provide soft, glare-free illumination. These fixtures, with their hidden light sources, add a modern and functional touch to the space, enhancing the visual experience. Additionally, concealed and indirect lighting complements the natural light in various parts of the project, creating a serene atmosphere throughout the interior. Outdoors, recessed linear lights with an IP67 rating were used, featuring polycarbonate diffusers that resist dust and water. This lighting solution plays a key role in crafting a modern and cohesive look for the outdoor areas, including the garden and entrances, elevating the overall beauty of the residential complex.
