Light Factors - essential to ensure the visual comfort of buildings - depend on Light Transmission (TL) and Exterior Light Reflection (RLE) and Interior Light Reflection (RLi), i.e. the percentage of light transmitted to the exterior or interior.
Luminous Transmittance is the percentage of visible light that is transmitted directly through the glass. The higher the light transmission, the more natural light is visible in the room, making it brighter.

Nowadays, natural light is privileged over artificial light for allowing greater visual comfort and greater energy savings.
