INTRODUCTION (not part of the proposal)
Changes introduced in IEC 60598-1 Ed.8.0 were made urgently to address completely new
designs of LED luminaire that are entering the market. Some further alignment with the
already existing previous requirements of the standard are still needed and this will be
addressed for Amendment 1 to Edition 8 that is now in preparation.
