Abstract
Devices, systems, and methods to predict a half-life or end of life for luminaire drivers are described. The drivers may include electronic drivers for light fixtures such as dimming controls that utilize electrolytic capacitors in the output circuit to smooth the output current and reduce changes in current amplitude. Half-life and end of life for the drivers may be predicted by monitoring failure variable indications of the driver and the luminaire light, including the light intensity depreciation of the light, and by evaluating the data from both the driver, light, and environment in which the driver and/or luminaire is installed to predict the most imminent half-life and/or end of life.
