15. The expert from IEC analysed the approval process of LED replacement light sources according to UN Regulation No. 37 (GRE-87-02), based on the full photometric equivalence according to the guidelines (GRE-83-15). According to him, full-equivalence solutions were not feasible for high flux categories with the today’s LED technology. As a consequence, some countries were issuing national approvals deviating from the full photometric equivalence, based on extensive testing (in headlamps and vehicles) for limited light source specifications and resulting in a positive list for particular vehicle models. GRE stressed the advantages of harmonization at the United Nations level and noted that several contracting parties were in favour of cautious re-evaluation of the equivalence criteria for LED replacement light sources. GRE invited IEC to start this work as a new activity of the Task Force on Substitutes and Retrofits (TF SR) in cooperation with those contracting parties. 15.
