EEI in ETIM Class EC002892

Hello everyone, Could someone help me with info about the EEI ( Energy Efficiency Index)? How is it different than Energy Efficieny classes? In the ETIM class EC002892, feature EF026118 - Energy Efficiency Index (EEI) requires numerical value and I do not know how to proceed with it. Thank you! Regards, Ivanka 

Hi Ivanka, maybe this document can help you?  https://ec.europa.eu/energy/sites/default/files/documents/Implementation%20Guide%20Lighting.pdf

Hello Marc, Thank you very much for your support!! Unfortunately, the document  itself  is not helping me as the regulation for EEI -  No 1194/2012, is no longer in force. Date of end of validity: 31/08/2021. However, it was an interesting reading and a  great input, directing me to the subsequesnt regulation EU) 2019/2020. In my understanding, the term EEI does not anymore exist and probably will be removed as a feature from the next ETIM edition.  Wishing you a great day!
