ErP Compliant LED Filament Bulbs: What European Buyers Must Know
The EU ErP Directive sets strict energy efficiency thresholds that eliminate most non-compliant LED filament products. Here is what compliance actually requires from a manufacturer.
The European Union's Ecodesign Regulation for light sources — commonly referred to as the ErP Directive — is one of the most demanding energy efficiency frameworks in the world. For buyers sourcing decorative LED filament bulbs for European distribution, ErP compliance is not optional. It is the legal baseline for market access.
Yet the gap between genuine ErP compliance and a supplier's claim of compliance is wider than many buyers realize. This guide explains what the ErP Directive actually requires, where decorative filament bulbs face the greatest compliance challenges, and how to evaluate a manufacturer's credentials before committing to a bulk order.
The ErP Directive: What It Actually Requires
The current framework governing light sources in the EU is Regulation (EU) 2019/2020, which came into force in September 2021 and replaced the older ErP lamp regulations. This regulation sets minimum energy efficiency requirements for light sources sold in the EU and EEA markets.
For LED filament bulbs — the decorative vintage-style products used in hospitality, retail, and architectural applications — the key metric is lamp efficacy, measured in lumens per watt (lm/W).
The regulation sets a minimum efficacy threshold of 85 lm/W for most light sources, with specific provisions for decorative lamps. This is where many decorative filament products struggle. The warm amber glow that makes vintage Edison bulbs visually appealing comes from a low color temperature (typically 1800K–2200K) and a high color rendering index (CRI 95+). Achieving these aesthetic properties while meeting the 85 lm/W efficacy threshold requires sophisticated LED filament engineering.
Products that do not meet the minimum efficacy threshold cannot legally be placed on the EU market. Distributors and importers who sell non-compliant products face regulatory action, product recalls, and potential liability.
The Decorative Lamp Exemption — and Its Limits
The regulation includes a specific category for decorative lamps, defined as light sources designed primarily for decorative purposes where the light output is secondary to the aesthetic form. This category has historically provided some flexibility for vintage filament products.
However, the exemption is narrowly defined. To qualify as a decorative lamp under EU 2019/2020, a product must meet specific criteria related to its construction and intended use. Manufacturers cannot simply label a standard filament bulb as "decorative" to avoid efficacy requirements.
Furthermore, even decorative lamps must comply with RoHS (Restriction of Hazardous Substances) requirements, which limit the use of mercury, lead, cadmium, and other restricted substances. For LED filament products, RoHS compliance is generally straightforward, but it must be documented.
What ErP Compliance Documentation Looks Like
A genuine ErP compliant LED filament bulb should come with a complete technical documentation package:
Declaration of Conformity (DoC). The manufacturer must issue a written Declaration of Conformity stating that the product meets all applicable EU regulations, including EU 2019/2020 and the Low Voltage Directive (EU 2014/35/EU). The DoC must identify the specific regulations, the product model numbers, and the authorized signatory.
Technical File. Behind the DoC sits a technical file containing test reports from an accredited laboratory, design documentation, and production quality records. Buyers do not typically receive the full technical file, but they should be able to request the test reports.
CE Marking. The CE mark on the product and packaging indicates the manufacturer's declaration of conformity with applicable EU directives. Note that CE marking is self-declared — it does not require third-party certification. The quality of the underlying technical documentation varies significantly between manufacturers.
Product Information Sheet. EU 2019/2020 requires manufacturers to provide standardized product information including efficacy (lm/W), color temperature, CRI, rated lifetime, and switching cycle performance.
The Efficacy Challenge for Warm-White Filament Bulbs
Here is the technical reality that separates serious ErP compliant manufacturers from those making unverifiable claims: achieving 85 lm/W at 2200K with CRI 95+ is genuinely difficult.
Standard LED technology produces more lumens per watt at higher color temperatures. A cool-white LED at 4000K might achieve 130 lm/W with relative ease. The same LED architecture tuned to 2200K for that warm amber filament appearance will produce significantly fewer lumens per watt — often falling below the 85 lm/W threshold.
Manufacturers who have solved this problem use advanced LED filament designs with optimized phosphor formulations, precision-engineered glass envelopes that maximize light extraction, and driver electronics tuned for efficiency at low wattages. This is not commodity manufacturing. It requires sustained R&D investment and rigorous production quality control.
When evaluating a supplier's ErP compliance claims for warm-white decorative filament bulbs, ask specifically for the measured efficacy values from accredited test reports — not just the claimed values on the specification sheet.
Verifying ErP Compliance Before You Order
The EU operates a market surveillance system where national authorities test products and report non-compliant items to the RAPEX database. Before placing a large order with a new supplier, it is worth checking whether their products have appeared in RAPEX notifications.
Beyond RAPEX, request the following from any supplier claiming ErP compliance:
- The Declaration of Conformity with the specific regulation number (EU 2019/2020)
- Test reports from an accredited laboratory (look for ILAC-accredited labs)
- The measured efficacy value (lm/W) from the test report — not the specification sheet
- Evidence of RoHS compliance (typically a separate test report)
A supplier who cannot provide these documents within a reasonable timeframe is not genuinely ErP compliant, regardless of what their marketing materials claim.
Luminaries Factory's Approach to ErP Compliance
Our LED filament bulbs for the European market are developed with ErP compliance as a design requirement, not an afterthought. We maintain complete technical documentation packages for all EU-market products, including Declarations of Conformity, accredited laboratory test reports, and product information sheets meeting EU 2019/2020 requirements.
Our technical sales team can provide full compliance documentation for any product in our catalog. For European distributors and importers, we offer documentation review calls to walk through the technical file before order commitment.
Minimum order quantities start at 300 units per SKU. Standard lead times for ErP compliant products are 25–35 days from order confirmation.
