Systems and methods for preventing or otherwise reducing cyclic light output caused by failure modes are disclosed, which shut off a power supply to a lighting system susceptible to output cycling (also known as flashing, flickering, or strobing) in a non-latching fashion. A power supply and/or driver system includes a processor and memory arrangement configured to track failures and prevent cyclical behavior when detected. The processor can be implemented, for example, with an existing microcontroller already present in the power supply, or as a dedicated processor. Once a failure mode that exhibits cyclic behavior above a certain frequency is detected, the power supply can be turned off or otherwise prevented from attempting to source power to the lighting system.
