Abstract: A lighting control system for a troffer LED lighting system is provided with a power supply having at least three pairs of wires extending therefrom. The first pair of wires is in connection with a power source. The second pair of wires is connected to a socket mounted to the troffer housing. The third pair of wires is connected to at least one LED. A socket resistor is mounted to socket to set a baseline brightness for the troffer LED lighting system, and an efficiency plug is provided for insertion into the socket. The efficiency plug includes an internal resistance to change the brightness of the troffer LED lighting system to a predetermined level.
