ANNEX IIIU.K. Ecodesign requirements

1.ENERGY EFFICIENCY REQUIREMENTSU.K.

1.1. Energy efficiency requirements for directional lamps U.K.

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

where:

Pcor 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.

Table 1

Correction factors

Scope of the correctionCorrected power (Pcor)
Lamps operating on external halogen lamp control gear
Lamps operating on external LED lamp control gear
Fluorescent lamps of 16 mm diameter (T5 lamps) and 4-pin single capped fluorescent lamps operating on external fluorescent lamp control gear
Other lamps operating on external fluorescent lamp control gear
Lamps operating on external high-intensity discharge lamp control gear
Compact fluorescent lamps with colour rendering index ≥ 90
Lamps with anti-glare shield

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

For models with Φuse < 1 300 lumen:

For models with Φuse ≥ 1 300 lumen:

Φuse is defined as follows:

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:

1.2. Energy efficiency requirements for lamp control gear U.K.

As from stage 2, the no-load power of a lamp control gear intended for use between the mains and the switch for turning the lamp load on/off shall not exceed 1,0 W. As from stage 3, the limit shall be 0,50 W. For lamp control gear with output power (P) over 250 W, the no-load power limits shall be multiplied by P/250 W.

As from stage 3, the standby power of a lamp control gear shall not exceed 0,50 W.

As from stage 2, the efficiency of a halogen lamp control gear shall be at least 0,91 at 100 % load.
