With the application of IT technology to the new building generation, lighting has taken a prime role in architecture. This can be witnessed in the Wilayah Mosque where natural light becomes one of the fundamental architectural components to enhance the aesthetic value and ambience of space. This fully automated lighting system in the Wilayah Mosque utilizes integrated daylight and artificial light that complement and balance each other.

Through multiple reflection sunlight from the cupola is focused on to the chandelier via a pyramid mirror, to provide diffused and brilliant light that gives depth and three-dimensionality to the space.

Natural daylight is also reflected into the upper areas by re-directional lamellae located at the dome windows. Made of highly reflective material, the lamellae automatically rotate along the longitudinal axis to track the sun's position at different times of the day.
