Light and luminaires play a central role in construction, both in planning and during the construction phase. Well-thought-out lighting not only ensures the functionality of a building, but also the safety and comfort of its users. On the construction site, temporary lighting ensures safe working conditions by making danger spots visible and enabling efficient work even in poor lighting conditions. When planning buildings, special attention is paid to selecting luminaires that are energy efficient while also meeting aesthetic requirements. Modern LED technologies and intelligent lighting control systems help to reduce energy consumption and create a pleasant atmosphere.
