Nowadays, light quality is a key differentiator in lighting. In general, quality of light refers to the visual aspects of light and its dependencies on and interaction with people and the environment. LEDification gives us endless possibilities to differentiate in spatial, spectral, and temporal light quality. It forces us to revise our traditional way of evaluating light quality.
