Investigation to determine representative values of n and k as constants in luminance equation to use in estimating disability glare from street lighting lanterns; on basis of new results and those from earlier investigations it is suggested that n should be taken as 2.2 and k as (0.2A plus 5.8) Pi where A is age of observer in years.
