  2. update the Conformity of Production requirements (CoP),
  3. reference the compliance requirements for installation contained in Regulations Nos. 48, 53, 72 and 86 for application as warranted
  4. clarify the definition of “type”, with regard to manufacturer, trade names and marks,
  5. introduce editorial improvements to the requirements for markings,
  6. remove the requirement to indicate the rated wattage in the marking of lamps equipped with electronic light source control gear and/or non-replaceable light sources and/or light source module(s).
