1. A lighting control apparatus comprising:
load regulation circuitry that includes inverter circuitry; and
control circuitry operatively coupled to the load regulation circuit, the control circuitry to, responsive to receipt of an input that includes data representative of a target intensity:
determine whether the received target intensity is greater than a defined threshold intensity value; and
responsive to the determination that the target intensity is greater than the defined threshold intensity value, cause the load regulation circuitry to operate in a first operating mode in which the duty cycle of the load regulation circuit is held constant and target current is varied to achieve a defined load current that corresponds to the target intensity; and
responsive to the determining that the target intensity is not greater than the defined threshold intensity value, cause the load regulation circuitry to operate in a second operating mode in which the target current is held constant and a duty cycle of the inverter circuitry is varied to achieve the load current that corresponds to the target intensity.
