The expert from the Task Force on Substitutes and Retrofits (TF SR) reported on their activities that address high power light-emitting diode replacement (LEDr) light sources (“LED retrofits”) based on “intelligent equivalence” and bi-directional emission (GRE-89-06). Specifically, he introduced an alternative equivalence specification for the light source H11_LEDr (GRE-89-05). The experts from France, Germany, United Kingdom and EC commented on the TF SR documents. GRE decided to continue the discussion at its next session.

The expert of GTB submitted editorial modifications to UN Regulations Nos. 37 (Filament light sources) and 128 (LED light sources) (ECE/TRANS/WP.29/GRE/2023/24 and ECE/TRANS/WP.29/GRE/2023/25, respectively). The expert from IEC proposed a correction to the first document (GRE-89-20).
