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:F1

• 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.
