A Note towards the Understanding of Lighting Quality

AbstractIt is perhaps to be regretted that the regular arrays of recessed luminaires, the most common way of lighting offices, are the least preferred. Possibly in a windowless environment the lack of any view to give visual variety exaggerated the low ratings of such situations. Possibly the quality of the luminaires (particularly the prismatic 'batwing' which was rated very low) could be improved. Possibly the experimental procedure which did not allow the subject to work for a long time in the same environment made variety more desirable. But certainly the indications from this study are that subjects prefer other ways than regular recessed luminaires to light their offices. Complexity and brightness together: perhaps that is what people want in the lighting of their offices.
