| Summary | Proposal to delete the requirement that the total objective luminous flux of all LED modules producing the principal passing (main low) beam of a headlamp be greater than or equal to 1000 lumens because the requirement is design-restrictive, unnecessary given the objective criteria for luminous output and photometric grid points of the regulation, and obsolete given improvements in LED technologies. | ||||||||

43. The expert from France proposed to delete a design restrictive requirement of a minimum luminous flux of 1,000 lm for LED in Regulations Nos. 112 and 123 (ECE/TRANS/WP.29/GRE/2014/35, ECE/TRANS/WP.29/GRE/2014/36, GRE-72-25). The expert from Poland proposed an alternative definition of photometric requirements (GRE-72-24). GRE supported the deletion of the 1,000 lm requirement, but could not agree with the requirement for light distribution of the beam pattern proposed as an alternative. GRE invited the expert from France, in cooperation with the expert from Poland, to prepare a revised proposal for consideration at the next session. All GRE experts were invited to contribute. 43.
