Using luminaires with high luminance efficiency may reduce the required number of luminaire installations in the ceiling,and as such effectively decrease the cost and save energy.However,it may also result in a negative effect on visual comfort.In this paper,we describe a subjective experiment to investigate the effect of spacing between luminaires on visual comfort.Results show that it’s possible to arrange luminaires with high luminance efficiency at a larger spacing,while still achieving lighting of comparable comfort and of similar perceived space brightness,when controlling the average horizontal illuminance of the lighting on the working area.
