Energy Star Certification for Lighting: Global High-End Market Access Key & GTG’s Solutions

Driven by the global wave of green consumption, Energy Star Certification has become synonymous with high quality and energy efficiency in the lighting industry. As a benchmark for voluntary certification, it is not only an authoritative endorsement of product performance but also a golden key for enterprises to open high-end markets and win consumer trust. The Lighting Testing Division of GTG Testing Group provides an in-depth analysis of the value and process of Energy Star Certification, helping your products stand out in the international market.

I. Energy Star Certification: A Market Pass Beyond Standards

Energy Star is jointly launched by the U.S. Environmental Protection Agency (EPA) and the Department of Energy (DOE). Although it is a voluntary certification, its market influence far exceeds that of many mandatory regulations. Obtaining Energy Star Certification means:

• Authoritative Endorsement: The product’s energy efficiency and performance meet the leading standards recognized by the U.S. government.
• Government Procurement Threshold: U.S. federal agencies and many state governments give priority to purchasing certified products.
• Consumer Trust: One of the most recognized energy efficiency labels among North American consumers, significantly boosting purchase intention.
• Eligibility for Energy-Saving Subsidies: Most public utility companies offer additional subsidies for certified products.

II. Applicable Product Scope & Technical Framework

Energy Star Certification covers a wide range of lighting product categories, mainly including:

• LED lighting fixtures (e.g., downlights, panel lights, street lights, high-bay lights);
• LED light sources (e.g., replacement LED bulbs, tubes);
• Traditional lighting products (e.g., CFL energy-saving lamps, fluorescent lighting fixtures).

Certification is mainly based on the latest technical standards such as Luminaire V2.2 and Lamp V2.1, imposing comprehensive requirements on product luminous efficacy, lifespan, and light quality.

III. Core Performance Requirements: Comprehensive Pursuit of Excellence

1. Strict Luminous Efficacy Requirements

• The overall luminous efficacy of the fixture must reach an industry-leading level.
• Corresponding minimum luminous efficacy limits are set for different product categories.

2. Excellent Light Quality Assurance

• Color Rendering Index (CRI) ≥ 80 (≥ 90 for some categories) to ensure true color reproduction.
• Chromaticity tolerance within 7 SDCM to guarantee color consistency.
• Correlated Color Temperature (CCT) must comply with specified ranges.

3. Long-Lifespan Verification

• A complete LM-84 test report must be provided.
• L70 lifespan must be calculated based on TM-28 or TM-21 methods.
• Most products require a lifespan of ≥ 25,000 hours.

4. Power Factor Requirements

• Power factor ≥ 0.9 for commercial/industrial products.
• Power factor ≥ 0.7 for residential products.

5. Other Special Requirements

• Dimming performance (if applicable).
• Flicker testing must meet specifications.
• Standby power consumption limits.

IV. Detailed Certification Process

1. Qualification Preparation: Manufacturers must first obtain Energy Star Partner qualification.
2. Product Testing: GTG conducts comprehensive testing in accordance with Energy Star standards.
3. Document Submission: Submit test reports and technical documents through the Energy Star online system.
4. Review & Listing: After EPA review and approval, the product is listed in the official certified product directory.
5. Market Supervision: Continuous compliance is required, and the product is subject to random EPA market inspections.
