Abstract: A lighting system and method are provided for controlling a PWM duty cycle. The lighting system is provided with at least one device that is configured to emit light in response to receiving electrical power. The lighting system includes a power circuit and a feedback circuit. The power circuit is configured to selectively supply power to the device at a duty cycle corresponding to a first mode and a second mode, wherein the duty cycle of the first mode is less than 10% of the duty cycle of the second mode. The feedback circuit is configured to provide a feedback signal that is indicative of the energy provided to the device. The power circuit is further configured to disable power to the device during the first mode in response to the energy being greater than a threshold energy value, thereby adjusting the duty cycle.
