Illumination sources are turned ON and turned OFF in response to detected levels of illumination in an ambient environment reaching respective thresholds, which may be user set. The detection of these turn ON and turn OFF events is verified, for instance against expected events or conditions for the particular location, date and/or time. An alert or log entry may be generated if a detected event or condition appears to be invalid. For instance, if an amount of illumination in the environment is different than predicted by a threshold amount or if a time that the event occurs or is detected is different than expected or predicted by more than a threshold amount. A level of illumination may be decreased to some non-zero level after a specified time after turn ON, and increased at some specified time before turn OFF. Use of information from external sources (e.g., satellites, cell towers) may allow times to be using local time, including daylight savings if applicable.
