Abstract
An illumination system verifies controls the operation of a luminaire without the use of any photometric data. The illumination system uses data indicative of a current time, date or latitude to determine one or more aspects of a solar event. Such aspects can include a scheduled, predicted or expected time of occurrence of the scheduled solar event. Responsive to the determination of a scheduled, predicted or expected time of occurrence of the scheduled solar event, a control subsystem can adjust the luminous output of a light source.
