Method of protecting and detecting a surge event in a node

Abstract

Devices and methods for protecting against a surge in a luminaire are provided. For example, a controller for use with a luminaire is provided. The controller can include a first circuit configured to sense a surge in voltage or current. The controller can further include a second circuit configured to switch a relay in response to the first circuit having sensed the surge in voltage or current.
