ASSIST recommends...A Method for Estimating Discomfort Glare from Exterior Lighting Systems

Published April 2011

Because outdoor lighting is utilized at relatively low light levels and because outdoor lighting equipment (e.g., lamps and luminaires) tends to be relatively bright, there is a substantial potential for discomfort glare in outdoor lighting applications. This volume of ASSIST recommends describes a calculation method for predicting discomfort glare from outdoor lighting systems, based on the existing De Boer (1967) rating scale and a published discomfort glare model.
