Recessed linear LED lighting lets architecture consistently take precedence. The integration of lighting and architecture is the hallmark of contemporary lighting design in commercial and institutional settings. The visual needs of commercial building occupants are complex. Lighting is a critical design element in sophisticated architectural projects. It may enhance or degrade both the visual performance and environmental perception of people that use the space. Beyond creating an environment that allows space users to perform tasks comfortably, effectively and safely, lighting must help compose comfortable and positive overall atmospheres and contribute to their health and wellbeing. From emotions, functions, perception and health to economics and the environment, commercial buildings such as office buildings, educational facilities, libraries, hospitals, and shopping centers impose diversified requirements on lighting. Recessed linear lighting offers a holistic solution to addressing the challenges faced by commercial lighting.
