1. LED Tube Market Overview & Necessity of CE Certification
LED T8 and T5 tubes are widely used energy-saving light sources in commercial lighting, industrial workshops and public buildings. Featuring low power consumption and long service life, they are gradually replacing traditional fluorescent tubes. The European Union maintains strong demand for energy-efficient lighting products, alongside strict regulations on product safety, electromagnetic compatibility and hazardous substance control.
CE (Conformité Européenne) marking is a mandatory entry requirement for products sold within the European Economic Area (EEA). Before launching into the EU market, LED tubes must complete CE conformity assessment, comply with all applicable EU directives and harmonized standards, affix the CE mark and issue the EU Declaration of Conformity (DoC).
Although LED tubes share the same product category as LED panel lights and bulbs, their special design — straight tubular shape, T-type connectors and compatibility requirements for existing ballasts — means they follow distinct safety standards. Manufacturers shall select applicable regulations accurately during certification.
2. Applicable EU Directives & Harmonized Standards for LED Tube CE
LED tubes shall comply with the following four core EU directives:
表格

4. CE Certification Route & Conformity Assessment Process
Most LED tubes adopt the self-declaration route for LVD and EMC. Third-party Notified Body review is not mandatory, but all tests must be completed by qualified laboratories.
表格
| Step | Procedure | Key Notes |
|---|---|---|
| 1 | Confirm applicable directives & standards | Distinguish double-ended retrofit tubes (EN 62776) and tubes with integrated drivers to apply correct standards |
| 2 | Compile Technical Construction File (TCF) | Prepare product description, circuit diagrams, BOM, risk assessment, test reports and DoC draft |
| 3 | Sample testing | Deliver samples to EU-recognized labs (TÜV, SGS, Intertek etc.) for full safety, EMC and RoHS tests |
| 4 | ErP compliance assessment | Calculate EEI to meet (EU) 2021/341 requirements and complete Product Information Sheet (PIS) |
| 5 | Issue Declaration of Conformity (DoC) | Signed by manufacturer or EU Authorised Representative to declare full regulatory compliance |
| 6 | Affix CE marking | Print CE mark directly on the tube or packaging; minimum character height: 5 mm |
| 7 | Archive technical documents | Retain full TCF for 10 years after product discontinuation for EU market surveillance |
5. Special Notes on ErP Ecodesign Requirements
Stricter energy rules under (EU) 2019/2020 and (EU) 2021/341 took effect in 2021:
- Minimum luminous efficacy: General-purpose linear LED tubes ≥ 100 lm/W (varies by power rating)
- Colour Rendering Index: Ra ≥ 80 (except for special applications)
- Energy Efficiency Index (EEI): Comply with current energy classification rules
- Energy Label: Follow (EU) 2019/2015 with A-G rating scale
- EPREL Registration: Register product parameters in the European Product Registry for Energy Labelling
Tip: Traditional fluorescent tubes have been phased out of the EU market since September 2021. All LED tubes sold in the EU must comply with ErP rules and complete EPREL registration.
6. Frequently Asked Questions (FAQ)
Q1: Differences between certification standards for T8 and T5 LED tubes? A1: Both follow the same EU directive framework. T8 tubes (26mm diameter) mainly apply EN 62776 for double-ended retrofit types. Most T5 tubes (16mm diameter) adopt integrated driver design and refer more to EN 60598 and EN 61347 series. Confirm standard versions with laboratories before testing.
Q2: Is an EU Authorised Representative mandatory? A2: Non-EU manufacturers must appoint an Authorised Representative based within the EEA. The representative is responsible for document custody, market surveillance coordination and DoC signing, which is a legal requirement for EU sales.
Q3: Can old CE test reports continue to be used? A3: EU harmonized standards are updated regularly. If referenced standards are revoked and replaced by new versions, old reports become invalid and re-testing is required. Review document validity every 1–2 years.
Q4: Are energy labels compulsory for LED tubes? A4: Yes. Per (EU) 2019/2015, LED tubes as light sources must carry the new A-G energy label on packaging and complete EPREL registration. Both are mandatory for legal market access.
Q5: Is re-certification required after product modification (e.g. LED chip replacement)? A5: Re-testing and document update are required if changes affect safety, EMC or energy performance (driver, LED chip, circuit structure etc.). Minor appearance adjustments or irrelevant material replacement only need record updates in TCF without re-certification.
