Abstract
A gas discharge lamp including a power supply connectable to a load, and an overvoltage-protection-and-ground-fault-interrupt (OVP/GFI) circuit interconnected with the power supply. The OVP/GFI circuit includes an overvoltage-protection (OVP) sub-circuit that deactivates the power supply when an overvoltage condition is detected, and a ground-fault-interrupt (GFI) sub-circuit that deactivates the power supply when a ground-fault condition is detected.
