Instead, this edition of the Handbook recognizes 23 criteria; these include both vertical and horizontal illuminance, glare, appearance of space and luminaires and many others. Attention is given to the relative importance of each criterion for a particular location. The occupants' age and room surface reflectance are also taken into account, although not considered in sufficient detail; the Handbook recommends other resources to be consulted for guidance on the effects of age on the quantity and quality of lighting.

Another significant shortcoming noted was the lack of sufficient guidance on the design of lighting systems for shift workers, despite the fact that one in five workers in the United States is a shift worker and the well known fact that lighting can make it easier or more difficult to stay alert.

Despite these shortcomings, the new edition of the Handbook is considered to be a masterly compilation with a wealth of useful detail to assist the lighting designer. Authors: Wotton, E. Publication Date: Nov 01,
