1. A dim-to-warm lighting system comprising:

  • a first light channel including a white light emitting diode having a first correlated color temperature and in electrical communication with the current drive;

    a first current control controlling a first current through the white light emitting diode of the first light channel based on a first current value;

    a second light channel having a second correlated color temperature different than the first correlated color temperature and in electrical communication with the current drive;

    a second current control controlling a second current through the second light channel based on a second current value;

    a dimming curve adjustment interface outputting a correlated color temperature signal; and

    a controller receiving the measured current value from the current measuring device, the controller configured to;

    determine a light control value from the measured current value,using the light control value, determine the first current value for the first current control,using the light control value, determine the second current value for the second current control, andprovide the first current value to the first current control and the second current value to the second current control.
