A lamp arrives with CE mark, ENEC certificate and EPREL registration, and many buyers will default to these three components. They're not close, and figuring out what each item represents directly changes how much you trust it.

CE is a manufacturer's declaration of conformity and not a third-party approval. The manufacturer declares itself that the product meets the applicable directives and signs a Declaration of Conformity (DoC). For mains powered lamps, these directives typically include the Low Voltage Directive 2014/35/EU, the Electromagnetic Compatibility Directive 2014/30/EU, and the revised Restriction of Hazardous Substances Directive 2011/65/EU. Its conformity assessment path is mainly self-declaration, so the documents that are really worth requesting are the DoC and the supporting test report.

ENEC and GS are different in nature. ENEC is a third-party certification operated by European testing agencies for specific product standards, and GS is a voluntary safety mark in Germany. Both include sample testing in independent laboratories and-which is particularly important-include ongoing factory supervision inspections. Continuous supervision is the fundamental difference between them and a one-time test report.

EPREL is a database, not a logo. According to the ecological design and energy efficiency labeling rules, light sources must complete the "European Product Energy Efficiency Labeling Registry"(EPREL) registration before being put on the EU market, and the registration is bound to specific models and energy efficiency labels. It should be noted that the registration obligation falls on the light source itself: if the whole lamp uses a separately registered light source module, then the registered object is not the whole lamp-when the supplier reports a registration number, this difference is worth checking.
