Perceived adequacy of illumination

Current lighting standards drive general practice towards installations which direct high proportions of the lamp lumens downwards onto the horizontal work plane, thereby dictating the lighting distribution that has to be provided to satisfy energy efficiency standards and sustainability ratings. This paper challenges the basis of the standards that currently guide general lighting practice, and proposes a radically different criterion for specifying illumination adequacy. This has profound implications for lighting designers, giving new freedom to apply design creativity.
