Several new spatial brightness evaluation methods have been proposed in recent years. Although these new methods provide us to evaluate spatial brightness which is difficult by measuring horizontal illuminance, there is little agreement for a room with uneven distribution of light. In this study, we examined the relationship between spatial brightness, suitability of spatial brightness and luminance distribution for such a non-uniformly illuminated room. We found applied conditions of averaged
