1. A method of providing light, the method comprising:

  • receiving an AC voltage input at a first frequency at a driver, the driver being configured to receive a voltage level of the AC voltage input to produce a voltage output from the driver, the AC voltage input being one of at least two different AC forward voltages that are capable of being received by the driver;

    transforming the AC voltage input at the first frequency to the voltage output using the driver, wherein a voltage of the voltage output is relatively constant when the driver is connected to at least two LED circuits and returns to a relatively constant voltage output after an LED circuit in series or in parallel with the at least two LED circuits is switched in or out from an output of the driver;

    supplying the voltage output to the at least two LED circuits;

    monitoring the voltage level at the output of the driver;

    sending a signal to an internal control circuit based on monitoring of the voltage level;

    determining whether the voltage output of the driver has a relatively constant voltage; and

    responsive to the output of the driver not having the relatively constant voltage during a change in a number of LED circuits connected to the driver, adjusting the voltage level of the voltage output of the driver using the internal control circuit so that the voltage output remains relatively constant.
