1. A lighting system controller to control illumination provided by a plurality of lighting fixtures disposed in a space, the controller comprising:
memory circuitry;
communication circuitry; and
lighting system controller circuitry communicatively coupled to the memory circuitry and to the communication circuitry, the lighting system controller circuitry to:
retrieve fixture capability information including an illumination parameter range from each respective one of the plurality of lighting fixtures disposed in the space;
determine a space capability using the retrieved fixture capability information received from each of the plurality of lighting fixtures;
determine a color mixing curve using the fixture capability information retrieved from each of the plurality of lighting fixtures;
responsive to receipt of a desired target illumination parameter, determine whether the desired target illumination parameter falls outside the determined space capability;
responsive to the determination that the desired target illumination parameter falls outside the determined space capability, identify as a low-performing light fixture one or more lighting fixtures that, when placed in an ILLUMINATED state, would cause the target illumination parameter to fall outside the determined space capability;
transmit one or more first instructions that cause the one or more identified low-performing lighting fixtures to transition to a NON-ILLUMINATED state;
transmit one or more second instructions that cause the remaining plurality of lighting fixtures to transition to an ILLUMINATED state to provide the target illumination parameter;
determine power consumption as a function of the determined color mixing curve based on the power consumption of each of the plurality of lighting fixtures at a defined point on the color mixing curve; and
control intensity of the plurality of lighting fixtures to maintain the determined power consumption below a defined power consumption threshold.
