1. A pre-programmed energy management ballast or driver, comprising:
- a power circuit operative to selectively convert power from an AC input into a form suitable for driving a light source;
a profile control component pre-programmed to control the provision by the power circuit of electrical power to the light source according to a pre-programmed energy profile as a function of a current time value;
a bypass component operatively coupled to the AC input to sense a predefined on/off pattern in application and removal of AC input power at the AC input, the bypass component providing a signal or message to the profile control component to selectively affect profile control of the provision of electrical power to the light source based on the on/off pattern;
an internal clock component operative to provide the current time value to the profile control component; and
a sync input operative to start or program the internal clock component, where the sync input is operative to receive a current time signal from the AC input as simplex clock information, and to synchronize the internal clock component with a current time according to the received simplex clock information.

Abstract
A pre-programmed energy saving ballast or driver is presented, having a pre-defined energy profile to which the output power is controlled in accordance with the current time ascertained from the input power connection via simplex clock information or from received broadcast time signals, and which allows a user to select from a number of pre-programmed profiles and/or to modify and store user-defined energy profiles.
