The authors represent a research consortium which has adopted a task performance based approach for night-time driving to establish a system for photometry in the mesopic region. This article analyses the experimental investigations described in earlier articles of visual performance in the mesopic domain using reaction time, detection threshold and discrimination threshold techniques. These results are used to develop a system for mesopic photometry, which balances the quality of the fit to the experimental data with the ease of practical implementation by the lighting industry. A more complex model is also described, which takes account of the chromatic visual response channels and thus provides a better fit to some of the experimental results (particularly those involving monochromatic stimuli), but describes the totality of the data less well and is furthermore less suitable for practical photometric measurements.
