Abstract
An LED lighting device comprises at least one LED selectively energizable to develop light and a control circuit coupled to the LED that develops a command signal comprising first and second command signal components for controlling the at least one LED to cause the LED to develop light comprising a desired brightness in response to the first command signal component. The control circuit controls the at least one LED to cause the LED to develop light comprising a further desired parameter magnitude other than desired brightness in response to the second command signal component, and the first signal component comprises an IEC 0-10 volt analog lighting control.
