In accordance to clause C.5.3 of IEC 61000-3-2, “If separate tests with reference lamps have proved that ballasts for fluorescent or other discharge lamps or step-down converters for tungsten halogen or other filament lamps, comply with the requirements, the luminaire is deemed to comply with these requirements and need not be checked. Where these components have not been approved separately, or do not comply, the luminaire itself shall be tested and shall comply”.
