1. A lighting fixture, comprising:

  • a first ballast for illuminating a first light and a second ballast for illuminating a second light;

    a motion sensor;

    a radio frequency transceiver; and

    a circuit coupled to the first ballast, the second ballast, the motion sensor, and the radio frequency transceiver;

    wherein the circuit is configured to cause the first ballast to be in an activated state of operation such that the first light is illuminating and the second ballast to be in a deactivated state of operation such that the second light is not illuminated;

    wherein the circuit is further configured to receive a signal from the motion sensor and to determine whether the signal is representative of motion;

    wherein the circuit is further configured to respond to a determination that the signal is representative of motion by causing the second ballast to enter an activated state of operation such that the second light is illuminated;

    wherein the circuit is further configured to cause the radio frequency transceiver to transmit at least one of a message indicating motion and an illuminate command for receipt by other lighting fixtures.
