of filament lamp,
             (b) In the case of LED light sources of 6.75 V, 13.5 V or 28.0 V; the luminous flux value produced shall be corrected. The correction factor is the ratio between the objective luminous flux and the mean value of the luminous flux found at the voltage applied.
7.2.                                    All measurements on lamps equipped with non-replaceable light sources (filament lamps and other) shall be made at 6.75 V, 13.5 V or 28.0 V respectively, when not supplied by an electronic light source control gear.
7.3.                                    In the case of a system that uses an electronic light source control gear being part of the lamp,[4] shall be applied at the input terminals of the electronic light source control gear a voltage of 6.75 V, 13.5 V or 28.0 V respectively.
7.4.                                    In the case of a system that uses an electronic light source control gear not being part of the lamp the voltage declared by the manufacturer shall be applied to the input terminals of the lamp. The test laboratory shall require from the applicant the light source control gear needed to supply the light source and the applicable functions.
The voltage to be applied to the lamp shall be noted in the communication form in Annex 1 of this Regulation.
7.5.                                    For any lamp except those equipped with filament lamps, the luminous intensities, measured after one minute and after 30 minutes of operation, shall comply with the minimum and maximum requirements. The luminous intensity distribution after one minute of operation can be calculated from the luminous intensity distribution after 30 minutes of operation by applying at each test point the ratio of luminous intensities measured at HV after one minute and after 30 minutes of operation.
8.                                          Colour of light emitted
The colour of the light emitted inside the field of the light distribution grid defined in paragraph 2. of Annex 3 shall be white. For testing see Annex 4 to this Regulation. Outside this field, no sharp variations of colour shall be observed.

9.                                          Conformity of production
The conformity of production procedures shall comply with those set out in the Agreement, Appendix 2 (E/ECE/324-E/ECE/TRANS/505/Rev.2), with the following requirements:
9.1.                                    Lamps approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set forth in paragraphs 6. and 8. above.
9.2.                                    The minimum requirements for conformity of production control procedures set forth in Annex 5 to this Regulation shall be complied with.
9.3.                                    The minimum requirements for sampling by an inspector set forth in Annex 6 to this regulation shall be complied with.
9.4.                                    The Type Approval Authority which has granted type approval may at any time verify the
