1. A method of controlling a light fixture, the method comprising:
receiving a set of inputs via manual control positioned on the light fixture, the set of inputs indicating an intensity and a color temperature for light emitted by the light fixture;
setting a first duty cycle of a first control signal for a first set of light-emitting diodes (LEDs), having a first color temperature, to cause the light fixture to emit light having the intensity and the color temperature;
setting a second duty cycle of a second control signal for a second set of LEDs, having a second color temperature different from the first color temperature, to cause the light fixture to emit light having the intensity and the color temperature;
receiving an external instruction from an external device via a radio, the external instruction indicating an updated intensity and an updated color temperature for light emitted by the light fixture; and
overriding the set of inputs with the external instruction by updating the first duty cycle and the second duty cycle to cause the light fixture to emit light having the updated intensity and the updated color temperature.
