1. A luminaire disposed in a hazardous environment in which an industrial process is being controlled, the luminaire comprising:
one or more drivers coupled to one or more illumination sources and powered by at least a first portion of power received by the luminaire to operate the one or more illumination sources to provide illumination in the hazardous environment in which the industrial process is being controlled;
one or more memories storing respective intrinsically-safe (IS) power configurations for one or more external IS devices that are disposed in the hazardous environment and that are utilized to control the industrial process, each of the one or more external IS devices being a respective process controller, solenoid driver, safety controller, another type of process control driver, safety logic solver, I/O device, actuator, pump, or valve;
one or more power distribution ports via which IS DC power is delivered to the one or more external IS devices in accordance with the respective IS power configurations, the IS DC power comprising a conversion, by the luminaire, of at least a second portion of the power received by the luminaire; and
computer-executable instructions stored on the one or more memories and executable by one or more processors of the luminaire to cause the luminaire to transmit, via one or more communication interfaces to one or more recipient devices, one or more signals pertaining to the IS DC power.
