A system for programming control of ballast illumination includes receiving a power stage input current through a first ballast input, receiving a level switch control signal at a second ballast input, entering a ballast illumination program mode, adjusting said level switch control signal to select a ballast lamp illumination and saving a field-programmed ballast lamp illumination indication in a ballast memory as representative of said ballast lamp illumination.
