1. ENERGY EFFICIENCY REQUIREMENTS U.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:

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.

Table 1

Correction factors

Scope of the correction	Corrected 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

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:

For models with Φ_use ≥ 1 300 lumen:

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.

Table 2

Application date	Maximum energy efficiency index (EEI)
	Mains-voltage filament lamps	Other filament lamps	High-intensity discharge lamps	Other lamps
Stage 1	If Φuse > 450 lm: 1,75	If Φuse ≤ 450 lm: 1,20 If Φuse > 450 lm: 0,95	0,5	0,5
Stage 2	1,75	0,95	0,5	0,5
Stage 3	0,95	0,95	0,36	0,2

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.

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.
