Abstract
Investigations in classrooms reveal that disturbing reflections on display screens are the primary complaint regarding the visual environment: in the classroom of the future such screens and hence complaints are expected to increase in quantity. An experiment was carried out to investigate the relationship between lighting, visual acceptability and luminous properties of display screens. This article presents preliminary results from tests using the adjustment method. The results suggest that the limits of luminaire luminance prescribed in current guidance, BS EN 12464-1:2002 and SLL Lighting Guide 7, are too low - modern display screens can tolerate higher luminances.
