In embodiments of the present invention improved capabilities are described for providing intelligent power control in response to an external power interruption, causing a processor is in an electrical fixture to interrogate an external power control switch to gain an understanding of the switch's state, where prior to the external power interruption the electrical fixture may be powered by external power and where external power may be connected and disconnected by a user of the switch. In the event that the switch's state is determined to be such that it would normally pass power to the electrical fixture, the processor causes the electrical fixture to operate using a backup power supply. In the event that the switch's state is determined to be such that it would normally not pass power to the electrical fixture, the processor causes the electrical fixture to act as if the user of the switch has intentionally removed power. In response to a return of external power, powering the electrical fixture is then through external power where the user of the switch switches external power.
