# Commission Regulation (EU) No 1194/2012 of 12 December 2012 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for directional lamps, light emitting diode lamps and related equipment (Text with EEA relevance) (revoked), Division (a): As from stage 2, equipment designed for installation between the mains and the lamps shall comply with state-of-the-art requirements for compatibility with lamps whose energy efficiency index (calculated for both directional and non-directional lamps in accordance with the method set out in point 1.1 of this Annex) is at most:

Extent: E+W+S+N.I.
Status: repealed

0,24 for non-directional lamps (assuming that Φ use = total rated luminous flux);
0,40 for directional lamps.
When a dimming control device is switched on at its lowest control setting for which the operated lamps consume power, the operated lamps shall emit at least 1 % of their luminous flux at full load.
When a luminaire is placed on the market and lamps that the end-user can replace are included with the luminaire, these lamps shall be of one of the two highest energy classes, according to Delegated Regulation (EU) No 874/2012, with which the luminaire is labelled to be compatible.
