Division 1.1 Energy efficiency requirements for directional lampsF1

The energy efficiency index (EEI) of the lamp is calculated as follows and rounded to two decimal places:

where:

P_cor is the rated power measured at nominal input voltage and corrected where appropriate in accordance with Table 1. The correction factors are cumulative where appropriate.

P_ref is the reference power obtained from the useful luminous flux of the lamp (Φ_use) by the following formula:

For models with Φ_use < 1 300 lumen: $P_{\mathrm{ref}}=\mathrm{0,88}\sqrt{{\Phi }_{\mathrm{use}}}+{\mathrm{0,049\Phi }}_{\mathrm{use}}$

For models with Φ_use ≥ 1 300 lumen: $P_{\mathrm{ref}}={\mathrm{0,07341\Phi }}_{\mathrm{use}}$

Φ_use is defined as follows:

• directional lamps with a beam angle ≥ 90° other than filament lamps and carrying a warning on their packaging in accordance with point 3.1.2(j) of this Annex: rated luminous flux in a 120° cone (Φ_120°)

• other directional lamps: rated luminous flux in a 90° cone (Φ_90°).

The maximum EEI of directional lamps is indicated in Table 2.

Stage 3 for mains-voltage filament lamps shall apply only if no later than 30 September 2015, evidence is produced by the Commission through a detailed market assesment and communicated to the Consultation Forum that there are mains-voltage lamps on the market that are:

• compliant with the maximum EEI requirement in stage 3;

• affordable in terms of not entailing excessive costs for the majority of end-users;

• broadly equivalent in terms of consumer-relevant functionality parameters to mains-voltage filament lamps available on the date of entry into force of this Regulation, including in terms of luminous fluxes spanning the full range of reference luminous fluxes listed in Table 6;

• compatible with equipment designed for installation between the mains and filament lamps available on the date of entry into force of this Regulation according to state-of-the-art requirements for compatibility.
