# The Ecodesign for Energy-Related Products and Energy Information (Lighting Products) Regulations 2021, Paragraph 2: Energy efficiency requirements

Extent: E+W+S

Separate control gears
(1) The minimum energy efficiency requirements of a separate control gear operating at full-load are the values set out in Table 4.
Table 4
Minimum energy efficiency for separate control gear at full-load
Declared output power of the control gear (Pcg) or declared power of the light source (Pls) in W, as applicable
Minimum energy efficiency
Control gear for HL light sources
all wattages Pcg

Control gear for FL light sources
Pls ≤ 5
5 < Pls ≤ 100
100 < Pls
0.71
Pls/(2 × √(Pls/36) + 38/36 × Pls+1)
0.91

0.92
Control gear for LED or OLED light sources
all wattages Pcg
Pcg 0.81/(1.09 × Pcg 0.81 + 2.10 )
(2) For the purposes of this paragraph, the requirements of Table 4 apply to multi-wattage separate control gears in respect of the maximum declared power on which they can operate.
(3) Where a manufacturer or importer has declared in the technical documentation that a separate control gear has been designed for no-load mode, the no-load power Pno of the control gear must not exceed 0.5W.
(4) The standby power Psb of a separate control gear must not exceed 0.5 W.
(5) For a connected separate control gear—
(a) the networked standby power Pnet must not exceed 0.5 W;
(b) the allowable values for Psb and Pnet must not be added together.
(6) This paragraph is subject to the exemptions in paragraph 3(3) of Schedule 4.
