(c)the full-load condition is obtained; and
(d)when the user opts to reset factory defaults, the reference control settings are obtained.
(5) For light sources which allow the manufacturer of a containing product to make implementation choices that influence light source characteristics (for example, definition of the operating current, thermal design) and cannot be controlled by the user, the reference control settings are not required to be defined.
(6) Where sub-paragraph (5) applies, the test conditions used by the light source manufacturer are to be used for the purposes of checking whether a light source conforms to these Regulations.
