Annex A. Survey ILCOS L

Gives a coding system that covers all lamp categories. Will: improve communications about the different types of lamps; enable correct replacement of lamps; help in discussions concerning interchangeability and compatibility of products; create a closer relationship between international standards and manufacturers' literature; be used as a complementary marking on the luminaire; replace national and regional coding systems.
