The ERP and Ecodesign Regulations for Europe
Regulation (EU) No. 2019/2020 on Ecodesign outlines the required energy performance and environment levels
Regulation (EU) No. 2019/2015 on Energy labelling Labels outlining the efficiency band for lighting products
ENERGY EFFICIENCY CLASSES AND CALCULATION METHOD
The energy efficiency class of light sources shall be determined as set out in Table1, on the basis of the total mains efficacy ηTM, which is calculated by dividing the declared useful luminous flux Φuse (expressed in lm) by the declared on-mode power consumption Pon(expressed in W) and multiplying by the applicable factor FTM of Table 2, as follows: ηTM = (Φuse / Pon) x FTM (lm/W).
Table 1 - Energy efficiency classes of light sources
| Energy efficiency class | Total mains efficacy ηTM (lm / W) |
|---|---|
| A | 210 ≤ηtm |
| B | 185 ≤ηtm<210 |
| C | 160 ≤ηtm<185 |
| D | 135 ≤ηtm<160 |
| E | 110 ≤ηtm<135 |
| F | 85 ≤ηtm<110 |
| G | ηtm<85 |
Table 2 - Factors FTM by light source type
| Light source type | Factor FTM |
|---|---|
| Non-directional (NDLS) operating on mains (MLS) | 1.000 |
| Non-directional (NDLS) not operating on mains (NMLS) | 0.926 |
| Directional (DLS) operating on mains (MLS) | 1.176 |
| Directional (DLS) not operating on mains (NMLS) | 1.089 |
ECODESIGN REQUIREMENTS
For the purposes of compliance and verification of compliance with the requirements of this Regulation, measurements and calculations shall be made using harmonised standards the reference numbers of which have been published for this purpose in the Official Journal of the European Union, or other reliable, accurate and reproducible methods, which take into account the generally recognised state-of-the-art.
1. Energy efficiency requirements:
a. From 1 September 2021, the declared power consumption of a light source Pon shall not exceed the maximum allowed power Ponmax (in W), defined as a function of the declared useful luminous flux Φuse (in lm) and the declared colour rendering index CRI (-) as follows: Ponmax = C x (L + Φuse / (F x η)) · R;
where:
- The values for threshold efficacy (η in lm/W) and end loss factor (L in W) are specified in Table 1, depending on the light source type.
They are constants used for computations and do not reflect true parameters of light sources. The threshold efficacy is not the minimum required efficacy; the latter can be computed by dividing the useful luminous flux by the computed maximum allowed power.
- Basic values for correction factor (C) depending on light source type, and additions to C for special light source features are specified in Table 2.
- Efficacy factor (F) is:
1,00 for non-directional light sources (NDLS, using total flux)
0.85 for directional light sources (DLS, using flux in a cone)
- CRI factor (R) is:
0.65 for CRI ≤25;

Table 2 - Correction factor C depending on light source characteristics
| Light source type | Basic C value | Special light source feature | Bonus on C |
|---|---|---|---|
| Non-directional (NDLS) not operating on mains (NMLS) | 1.0 | FL or HID with CCT >5000 K | +0.10 |
| Non-directional (NDLS) operating on mains (MLS) | 1.08 | FL with CRI > 90 | +0.10 |

Where applicable, bonuses on correction factor C are cumulative.
The bonus for HLLS shall not be combined with the basic C-value for DLS (basic C-value for NDLS shall be used for HLLS).
Light sources that allow the end-user to adapt the spectrum and/or the beam angle of the emitted light, thus changing 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, shall be evaluated using the reference control settings.
The standby power Psb of a light source shall not exceed 0.5 W.
The networked standby power Pnet of a connected light source shall not exceed 0.5 W.
The allowable values for Psb and Pnet shall not be added togethe
