Abstract
The disclosure relates to devices, systems, and methods to set, adjust, and/or maintain lumen levels of luminaires in a lighting system, for example. The lights may be a plurality of Light Emitting Diode (LED)-based luminaires, which are part of a smart illumination system. In certain exemplary embodiments, sensor subsystems detect degradation of luminaire lumen levels and servers/gateways are used to adjust dimming controls to reestablish proper lumen levels and predict a half-life or end of life for the luminaires.
