1. A color temperature-controlled lighting system, comprising:
a plurality of lighting fixtures communicatively coupled via a network, each of the lighting fixtures including:
a plurality of light emitting diodes (LEDs);
LED driver circuitry operatively coupled to the plurality of LEDs;
communications interface circuitry;
memory circuitry to store a color temperature output data table that includes data representative of a color temperature output as a function of luminous intensity of each of the plurality of LEDs; and
control circuitry communicatively coupled to the LED driver circuitry, the communications interface circuitry, and to the memory circuitry, the control circuitry to, responsive to receipt of a signal that includes a color temperature output target value:
determine, using the stored color temperature output data table, a respective luminous intensity for each of the plurality of LEDs based on the received color temperature output target value; and
communicate one or more control signals to the LED driver circuitry to cause each of the plurality of LEDs to produce the respective determined luminous output intensity such that the lighting fixture produces a luminous output having the received color temperature target value; and
communicate, via the communications interface circuitry, the color temperature output target value to at least one other of the plurality of lighting fixtures.
