1. Overview of CE Certification for Wall Washer Lights
Wall washer lights are core products for architectural landscape lighting, widely applied on building facades, cultural venues, bridges and urban night scenery projects. To enter the EU market, LED wall washers must bear the CE mark to prove compliance with relevant EU directives and harmonized standards.
CE marking is a mandatory market access requirement under EU regulations. Manufacturers or their EU Authorized Representatives shall complete conformity assessment and issue the Declaration of Conformity (DoC) for legal sales. For high-power wall washers used in public areas, some EU member states require third-party review by an EU Notified Body.

4. Detailed Requirements for Ingress Protection (IP) Ratings
Wall washers are generally installed on outdoor building facades and exposed to rain, dust and drastic temperature changes for long periods. IP rating is a key assessment item for CE certification.
- IP65: Fully dust-tight + Protected against low-pressure water jets. Common rating for regular outdoor installation.
- IP66: Fully dust-tight + Protected against powerful water jets. Suitable for coastal areas and high-pressure washing environments.
- IP67: Fully dust-tight + Protected against temporary immersion (1 m depth for 30 minutes). Applied to ground-recessed wall washers and near-water locations.
- IP68: Fully dust-tight + Protected against continuous immersion at depths specified by the manufacturer. Designed for water features and poolside installation.
5. CE Certification Application Process
Step 1 Confirm applicable directives and standards Define all applicable directives according to product voltage, power, mounting type and built-in wireless modules.
Step 2 Prepare test samples Provide 6–10 samples covering all colour and power variants, together with complete product specifications and circuit diagrams.
Step 3 Laboratory testing Entrust accredited laboratories to conduct LVD safety, IP rating, EMC and RoHS tests.
Step 4 Compile technical documentation Assemble the Technical Construction File (TCF), including design drawings, BOM, test reports and risk assessment documents.
Step 5 Issue Declaration of Conformity The manufacturer signs the EU Declaration of Conformity (DoC) to declare full compliance with all applicable directives.
Step 6 Affix CE marking Apply the CE mark on products and packaging (minimum character height: 5 mm), and attach multi-language user manuals.
Step 7 Document retention Keep all technical files for at least 10 years for inspection by EU market surveillance authorities.
6. Common Issues & Compliance Recommendations
-
Extra EMC attention for RGB/RGBW wall washers PWM dimming circuits of RGB wall washers tend to generate extra radio disturbance. Conduct conducted and radiated tests under full-colour operating modes (white output, single colour, colour gradient) and adopt the worst-case test data for declaration.
-
Safety isolation for DALI / DMX interfaces For wall washers integrated with DALI or DMX512 control ports, verify electrical isolation between control circuits and main circuits complies with SELV requirements in EN 60598-1. Isolation transformers shall meet double or reinforced insulation standards.
-
Outdoor weathering resistance Considering diverse European climates, enclosure materials shall pass UV aging test (minimum 500 hours per EN ISO 4892-2) and salt spray test (96 hours per EN ISO 9227) to prevent cracking, colour fading and seal failure during long-term outdoor operation.
-
Marking & user manual requirements Clearly mark rated voltage, rated power, CE logo, manufacturer name & address, model number, IP rating and ambient temperature (ta) on products. User manuals shall be provided in major EU languages (at least English, French, German, Italian and Spanish).
