Abstract: The described embodiments relate to systems, methods, and apparatuses for identifying when one or more components of a luminaire (114) in a network of luminaires has malfunctioned as a result of an electrical event (112), and determining how neighboring luminaires (106) have been affected. An electrical event such as an overvoltage or transient can damage component(s) of luminaires that are closest to a point of origin of the electrical event. However, luminaires located further away from the point of origin can also be affected. Estimating such damage can be useful for planning maintenance of the luminaires and/or their components. Furthermore, when luminaires are equipped with the ability to collect data (220) related to electrical events, such as lightning strikes, their collected data can be provided as a service for assessing damage to nearby connected devices, and predicting future electrical events.
