1. A closed-loop light emitting diode (LED) drive circuit comprising:

  • at least one LED;

    a voltage source;

    a voltage regulator connected to the voltage source to provide a regulated voltage output;

    a one-time-programmable voltage source connected to an output of the voltage regulator;

    a current controlled drive circuit connected to the one-time-programmable voltage source for providing a drive current to the at least one LED in response to an output from the one-time-programmable voltage source; and

    an end of line tester for monitoring the light intensity of the LED device and a signal indicative thereof to said one-time-programmable voltage source, said one-time-programmable voltage source storing said light intensity value and using said light intensity value to control its output voltage to said current control drive circuit.
