The illuminance uniformity criterion used in electric lighting design has an influence on the appearance of the space and the energy consumption of the installation. A subjective study of the acceptability of illuminance differences between two desks was carried out in a simulated office at two room illuminances with light or dark desk tops. Results show that illuminance ratios between work stations of at least 0.7 are generally acceptable. Although there is a trend of decreasing acceptability at lower illuminance ratios, there are indications that under some conditions lower illuminance ratios may also be acceptable.
