Claim:
1. Apparatus for controlling power to a solid state lighting (SSL) device load comprising: a power circuit for receiving power from an external source; at least one power limit connected to the power circuit; at least one output current driver for supplying a load power to the SSL device load, the at least one output current driver connected to the at least one power limit; and a power limit controller; wherein the power circuit transmits the power to the at least one power limit which, in turn, transmits a current to the at least one output current driver; wherein the power limit controller directly or indirectly monitors a level of the load power and controls the at least one power limit to reduce the level of the load power for a predetermined period of time when the load power exceeds a predetermined power limit; wherein if the load power exceeds the predetermined power limit, the power limit controller internally generates and transmits a signal to the current source controller to control the load power to the load; wherein the signal is based on internal controls.
