Schedule 3 Ecodesign requirements for light sources and separate control gears

Light sources

(1)

The declared power consumption of a light source P_on must not exceed the maximum allowed power P_onmax (in W), defined as a function of the declared useful luminous flux Φ_use (in lm) and the declared colour rendering index CRI (-) as follows—

P_onmax = C × (L + Φ_use/(F × η)) × R;

where—

(a)

the values for threshold efficacy (η in lm/W) and end loss factor (L in W) are as specified in Table 2, according to the light source type;

(b)

basic values for correction factor (C) depending on light source type, and additions to C for special light source features are specified in Table 3;

(c)

efficacy factor (F) is—

(i)

1.00 for non-directional light sources (NDLS, using total flux);

(ii)

0.85 for directional light sources (DLS, using flux in a cone);

(d)

CRI factor (R) is—

(i)

0.65 for CRI ≤ 25;

(ii)

(CRI+80)/160 for CRI > 25,

rounded to two decimals.

For the purposes of this paragraph—

(a)

where applicable, additions on correction factor C are cumulative;

(b)

the addition for HLLS must not be combined with the basic C-value for DLS (basic C-value for NDLS must be used for HLLS);

(c)

light sources which allow the end-user to adapt the spectrum and/or the beam angle of the emitted light, resulting in changes to the values for useful luminous flux, colour rendering index (CRI) and/or correlated colour temperature (CCT), and/or changing the directional/non-directional status of the light source, must be evaluated using the reference control settings;

(d)

the standby power P_sb of a light source must not exceed 0.5 W;

(e)

the networked standby power P_net of a connected light source must not exceed 0.5 W;

(f)

the allowable values for P_sb and P_net must not be added together.

(3)

This paragraph is subject to the exemptions in paragraph 3(3) of Schedule 4.

The minimum energy efficiency requirements of a separate control gear operating at full-load are the values set out in Table 4.
