In case of general lighting, activity appears to be the lowest: Application of downlight or uplight for the front wall and the side walls, overcome higher complexity. The use of general lighting or downlight on the walls, generate higher harmony. (2)In case of working factor, in general, it shows that pendant light is suitable. Beside of pendantlight, working factor rate seems to be higher while the contrast become smaller. In case of leasure with family factor, it's evaluation rate seems to be higher following the contrast decreasing.
