Zusammenfassung:	An emergency lighting system for at least one arc discharge device, utilizing an impedance mismatch between the emergency lighting system and a ballast provided for normal 60 Hz. power operation. This emergency lighting system will be activated when a normal AC voltage source falls below a predetermined level, and operates the arc discharge devices in an instant-start lighting system mode without the requirement for active switching between the normal and emergency modes of operation.
