LED Lighting ErP Energy Efficiency Testing: Mandatory Compliance for EU Market Access

In an era where green and low-carbon development has become a global consensus, EU ErP energy efficiency testing has evolved from an optional requirement to a mandatory pass for lighting products entering the European market.

What Is ErP Energy Efficiency Testing for Lighting?

The EU ErP Directive (Energy-related Products Directive) is a core regulation under the CE Mark framework, aiming to standardize the ecological design and energy efficiency requirements of energy-related products. Based on the 2009/125/EC framework directive, it imposes strict environmental and energy efficiency requirements throughout the product’s entire life cycle—from raw material procurement, production, and use to disposal.

On December 5, 2019, the European Commission officially adopted the updated ErP Regulation (EU) 2019/2020, which became mandatory on September 1, 2021. It replaced the previous regulations (EC) No 244/2009, (EC) No 245/2009, and (EU) No 1194/2012.

Core Values

• Legal Mandate: Lighting products failing ErP conformity assessment are prohibited from being sold, distributed, or used in the EU market.
• Unified Technical Specifications: Provides a consistent ecological design and energy efficiency assessment framework for all EU member states.
• Sustainable Development: Drives energy conservation, emission reduction, and sustainable development across the EU.
• Foundation for CE Marking: ErP compliance is a prerequisite for obtaining the CE Mark, directly determining product market access eligibility.

Scope of Lighting Products Subject to ErP Testing

The ErP Directive applies to all lighting products placed on the EU market, categorized as follows:

By Product Type

• Light sources: LED lamps, fluorescent lamps, high-intensity discharge (HID) lamps, etc.
• Independent control gear: Dimmers, drivers, and other standalone power control devices.
• Combined products: Complete luminaires integrating light sources and control gear.

By Application Scenario

• Recessed luminaires: Downlights, grille lights, panel lights, etc.
• Fixed luminaires: Ceiling lights, chandeliers, wall lights, etc.
• Portable luminaires: Table lamps, floor lamps, etc.
• Appliances/furniture with integrated lighting: e.g., household appliances or furniture equipped with lighting functions.

Detailed Test Items

Test Items for Light Sources

• Light source power loss
• Useful luminous flux
• Standby power consumption
• Color rendering
• Beam angle (for directional light sources)
• Additional tests for LED/OLED light sources:Luminous flux maintenance rate, survival rate, color tolerance, color temperature
• Additional tests for LED/OLED mains-connected light sources:Phase shift factor, flicker, flicker effect

Test Items for Independent Control Gear

• Full-load efficiency
• No-load power consumption
• Standby power consumption

Other Key Test Items

• Luminous efficacy test: Measures the light output relative to power consumption.
• Power factor test: Critical parameter for evaluating lighting energy efficiency.
• Color temperature and uniformity test: Uses a spectrophotometer to measure color temperature consistency.
• Color rendering index (CRI) test: Assesses the ability to accurately render object colors.
• Durability test: Simulates real-world usage to evaluate long-term energy efficiency stability.

Detailed ErP Certification Process

1. Conformity Assessment

Manufacturers may choose one of two evaluation models as required by the ErP Directive:

• "Internal design control"
• "Environmental management system"

2. Compile Technical Documentation File (TDF)

Manufacturers must prepare a comprehensive TDF covering:

• Design for end-of-life disposal
• Manufacturing processes
• Operation guidelines
• Product information

3. Sample Testing

Submit samples to an accredited laboratory for testing.

Test Cycle

• Light sources: 3,600 hours + 5 working days
• Independent control gear: 5 working days

4. Issue Declaration of Conformity (DoC)

• Include basic product information and referenced standards.
• Signed by the manufacturer or authorized representative.

5. Affix CE Mark

• Complete testing for harmonized standards (EMC, LVD, etc.).
• Attach the CE Mark to a visible, durable location on the product.
