For LED lighting product exports and energy‑efficiency certification, an LM‑80 test report is an essential technical document.Whether applying for Energy Star, DLC, EU, or Australian market access, an authoritative LM‑80 report is critical to proving LED service life and performance.

With many testing labs on the market, how do you choose the right one?This guide explains how to select an LM‑80 laboratory and recommends a professional provider:Guangdong Meide Certification & Testing Technology Co., Ltd.

1. Why LM‑80 Testing Requires a Professional Lab

IES LM‑80 (published by the Illuminating Engineering Society of North America)is the standardized method for measuring lumen maintenance of LED packages, arrays, and modules.

It is not a simple lighting test:

• Long duration: minimum 6,000 hours (≈9 months); up to 10,000 hours
• Strict temperature control: testing at 55°C, 85°C, and manufacturer‑specified temperatures
• High traceability: precise environmental control and data recording required
• Widely used: combined with TM‑21 to calculate LED L70 lifetime and support luminaire energy certifications

An unqualified lab can produce invalid data and delay your market launch.

2. Key Criteria for Choosing an LM‑80 Lab

1. International Accreditation (CNAS / NVLAP)

Prioritize labs with:

• CNAS accreditation
• NVLAP or IAS accreditation (strongly recommended for North America, required for Energy Star & DLC)

2. Professional Equipment & Stability

High‑precision goniophotometers, integrating spheres, and professional aging racksto ensure stable long‑term testing and accurate measurements.

3. One‑Stop Service

4. LM‑80 FAQ

Q1: Is LM‑80 a certification?

A: No.LM‑80 is a test method standard, not a certification.Labs issue an LM‑80 test report (not a certificate) showing lumen maintenance over time.

Q2: What is LM‑80 used for?

A:

1. Verify LED component performance
2. Support luminaire energy certifications (Energy Star, DLC)With a valid LM‑80 + TM‑21 report, finished luminaires often avoid full 6,000‑hour aging.

Q3: How many samples are needed?

A:

• LED packages: minimum 20 samples
• COB / filament LEDs: 10+ samplesMore samples improve lifetime extrapolation reliability.

5. Conclusion

In the competitive LED lighting industry,authoritative LM‑80 data = faster market access + stronger global competitiveness.
