The effect a lighting system creates in an interior is strongly influenced by the properties of the room surfaces. Surface Reflectance greatly assists with light levels. Areas with low reflectance levels need more light to achieve the same lux levels.
Indirect Light works very well in areas with high reflectance surfaces. High reflectance areas soften shadows. In contrast, low reflectance surface accentuate shadows.
At Decrolux, we always try to understand surfaces in our projects, to more accurately calculate lighting levels.
