Introduction
For LED manufacturers, importers, and project contractors, ErP compliance is not optional—it is a legal requirement for entering the EU market.
Failure to comply can result in:
- shipment rejection at customs
- project delays in hospitality and commercial installations
- costly redesign and retesting
- legal liability for importers
A real-world case:
A lighting supplier failed to complete EPREL registration.
Result: €50,000 worth of LED products was held at a German port for over 3 weeks.
The critical question is:
Can your LED product legally enter the EU market?
ErP Compliance Checklist (SLR & ELR Verified)

What Regulations Actually Apply (SLR & ELR)
The ErP framework (2009/125/EC) is implemented through:
- (EU) 2019/2020 — Single Lighting Regulation (SLR)
- (EU) 2019/2015 — Energy Labelling Regulation (ELR)
Official sources:
Core Concept
- SLR (ErP) → defines minimum technical performance
- ELR (Energy Label) → defines efficiency class (A–G)
You must pass SLR first before applying ELR labeling.
EU Energy Label Reality
Key Industry Fact
Most compliant LED products today fall between Class D–F.
- Class A (>210 lm/W) → extremely rare
- Class B–C → premium products
- Class D–F → mainstream compliant products
Do not reject products simply because they are not Class A.
Key ErP Technical Requirements
Core Performance Parameters (Regulatory + Market Reference)
| Parameter | Requisito | Type | Critical Note |
|---|---|---|---|
| Luminous efficacy | Not fixed (ηTM-based under EU SLR) | Regulatory | Cannot be simplified as lm/W threshold |
| Standby power (Psb) | ≤0.5 W (≤2.0 W network standby) | Regulatory | Important for smart / connected lighting |
| Lifetime | 15,000–25,000h (L70B50 typical) | Market | Not a mandatory EU requirement |
| CRI (Ra) | ≥80 (general lighting) | Regulatory | ≥90 recommended for retail |
| Pst LM | ≤1.0 | Regulatory | Short-term flicker |
| SVM | ≤0.4 | Regulatory | Stroboscopic effect safety |
How to Calculate LED Efficacy
To verify compliance, efficacy must be calculated as:
Luminous Efficacy (η) = Total Luminous Flux (lm) / Power Input (W)
Example
- 900 lm / 10 W = 90 lm/W → PASS
- 800 lm / 10 W = 80 lm/W → FAIL
This is one of the most common failure points in EU inspections.
Minimum Efficacy by Product Type (Market Reference, Not Regulatory Limit)
| Tipo de producto | Typical Market Range (lm/W) | Key Influencing Factors |
|---|---|---|
| Non-directional lamps | 90–130 lm/W | Thermal design, driver efficiency |
| Directional lamps (GU10) | 70–110 lm/W | Beam angle, optical losses |
| High-output lamps | 110–160+ lm/W | Power level, heat dissipation |
Always verify category-specific requirements before testing.
Why Flicker Metrics Matter
- Pst LM → visible flicker
- SVM → motion distortion
These are frequent failure points in EU compliance audits.

Common Reasons LED Products Fail ErP Compliance
❌ Low Efficiency (<85 lm/W)
- outdated LED chips
- poor optical design
❌ High Standby Power (>0.5 W)
- inefficient drivers
- leakage in dimming circuits
❌ Missing EPREL Registration
- product not in EU database
- automatic customs rejection
❌ Incomplete Technical Documentation
- missing test reports
- no Declaration of Conformity
❌ Thermal Mismatch (Ta vs Real Use)
- tested at 25°C
- installed at 40°C+
leads to real-world failure
Manufacturer Insight
Over 60% of ErP failures are caused by documentation—not product performance.
EPREL Registration: What You Actually Need
EPREL database:
https://eprel.ec.europa.eu
Required Data
- product datasheet
- energy label parameters
- test reports (efficacy, power, flicker)
- supplier account (EU-based)
Critical Rule
EPREL registration must be completed before placing the product on the EU market

Key Rule
The importer is legally responsible for placing compliant products on the EU market.
Compliant vs Non-Compliant LED Products
| Aspect | Compliant Product | Non-Compliant Product |
|---|---|---|
| Customs | Pass | Rejected |
| EPREL | Registered | Missing |
| Performance | Verified | Unstable |
| Legal Risk | Bajo | Alta |
