In today’s competitive lighting industry, ensuring product quality, performance, and compliance is essential for manufacturers and importers. LED lighting products must meet strict testing standards to gain market acceptance and regulatory approval. Among these, LM-79 and LM-80 LED testing standards are the most important benchmarks used worldwide to evaluate LED performance and longevity.
This blog provides a complete guide on LM-79 LM-80 LED testing, including the testing process, requirements, and the role of professional testing labs and consultants in India.
What is LM-79 LED Testing?
LM-79 is a standard developed to measure the electrical and photometric performance of LED lighting products. It applies to complete LED luminaires, not just individual components.
Key Parameters Tested in LM-79:
- Total luminous flux (light output)
- Power consumption (watts)
- Luminous efficacy (lumens per watt)
- Color temperature (CCT)
- Color rendering index (CRI)
LM-79 testing ensures that the LED product delivers accurate lighting performance as claimed by the manufacturer.
What is LM-80 LED Testing?
LM-80 focuses on the lumen maintenance and lifespan of LED light sources. Unlike LM-79, it tests LED chips, modules, or packages rather than finished products.
Key Aspects of LM-80 Testing:
- Lumen depreciation over time
- Performance under controlled temperatures
- Long-term reliability (typically tested up to 6,000–10,000 hours or more)
LM-80 data is often used along with TM-21 calculations to estimate the expected life of LED products.
LM-79 LM-80 LED Testing Process & Requirements
Understanding the testing process is crucial for manufacturers aiming for certification and compliance.
LM-79 Testing Process:
- Sample Selection – Complete LED luminaire is selected.
- Stabilization – Product is operated until thermal stability is achieved.
- Measurement – Photometric and electrical parameters are measured using integrating spheres or goniophotometers.
- Reporting – A detailed LM-79 test report is generated.
LM-80 Testing Process:
- LED Source Testing – LED packages/modules are tested.
- Controlled Environment – Testing is conducted at specific temperatures (e.g., 55°C, 85°C).
- Long Duration Testing – Continuous testing for thousands of hours.
- Data Analysis – Lumen maintenance curves are plotted.
How to Perform LM-79 LM-80 Tests on LEDs
To perform these tests effectively, manufacturers must follow strict guidelines and use accredited laboratories.
Steps to Perform Testing:
- Choose a certified and experienced LED testing lab
- Ensure product samples meet testing requirements
- Provide technical specifications and documentation
- Monitor testing timelines and compliance procedures
- Review and validate final test reports
Due to the complexity of the process, many businesses rely on LM-79 LM-80 test consultants for end-to-end support.
LED Testing for Certification & Compliance
LED testing is mandatory for obtaining various certifications and approvals in India and global markets. These include:
- BIS certification for LED products
- Energy efficiency labeling
- International export compliance
Without proper LM-79 and LM-80 test reports, manufacturers may face delays or rejection in certification processes.
LED Light Performance Testing (LM-79 LM-80)
Performance testing plays a vital role in determining:
- Energy efficiency
- Product durability
- Light quality
- Market competitiveness
By conducting LED light performance testing, companies can ensure their products meet industry standards and customer expectations.
