LM 79 & LM 80
An overview of LM 79 and LM 80 certification testing
Do you need LM 79 and LM 80 certifications for your product? Currently, every LED manufacturer, designer, and specifier strives for LM 79 and LM 80 certification because it determines the LED’s performance and durability. Needless to mention, the LED lighting market has seen a significant increase in demand in recent years. As a result, the industry has seen a rise in product effectiveness as well as a decrease in the cost of LED lighting products.
However, product effectiveness is lacking in some areas and requires development in performance and efficiency. Common industry challenges include energy efficiency, color crap, current droop, and others. All of this not only harms the goods and the company’s reputation but customers are likely to purchase any of the products in the future.
To meet these hurdles, you’ll need professionals who can assist you in obtaining LM 79 and LM 80 certification, which emphasises your product’s effectiveness and performance. UMSPCS has assisted enterprises and manufacturers all around the world in obtaining LM 79 and 80 certifications. Our experts will assist you in bringing your LED lighting product to market. Before we go into why you should hire us, let us assist you to understand what LM 79 and LM 80 are. Why are these certifications required for your product?
What is LM 79?
The electrical and photometric measurement of solid-state lighting products is known as LM 79. It was introduced to define how the performance of an LED bulb or fixture should be measured. With the increased use and development of LED technology, the demand for standardized LED testing processes became greater than ever—hence the launch of LM 79.
An LED bulb or fixture is measured using either an integrating sphere or a goniophotometer device. The LM 79 method requires that any LED bulb or fixture be tested at a single temperature and at a single point in time. This means that while it measures LED performance, it does not provide insights into how that performance may change under different temperature conditions.
The certified method, officially known as IES LM-79-19, ensures standardized testing of LED products for accurate and reliable data reporting.
Why is LM 79 Certification Needed More Than Ever?
Whether you are a manufacturer, seller, specifier, or designer intending to sell your LED products in various markets across different countries, obtaining LM 79 clearance is essential. It allows you to verify product quality across multiple standards and assists in evaluating several critical parameters.
LM 79 testing includes two core types of measurements: electrical and optical. Electrical measurements cover aspects like RMS AC voltage, AC active power, power factor, and voltage frequency. Optical measurements include data such as luminous efficacy, total luminous flux, chromaticity coordinates, and color rendering index (CRI).
With standardized LM 79 reports, stakeholders can trust that the product performs as claimed and complies with international standards—making it a crucial step in LED product commercialization.
What is LM 80?
LM 80 is a standardized method introduced to measure the lumen maintenance of LED light sources such as packages, arrays, modules, and more—under varying temperature conditions. This test is crucial in evaluating how well an LED maintains its brightness over time.
Developed and approved by the Illuminating Engineering Society of North America (IESNA), LM 80 is a globally recognized benchmark that LED manufacturers must adhere to in order to validate their product’s performance and projected lifespan.
Obtaining LM 80 compliance not only demonstrates your product’s reliability but also supports its entry into international markets, with only minor regulatory variations depending on the region. It is a key element in building customer trust and ensuring long-term lighting efficiency.
Why is Getting LM 80 Certification Essential?
Every designer, manufacturer, and specifier who wishes to launch a product in the Indian or foreign markets must obtain LM 80 certification or approval. LM 80 provides standardized testing for various LED products, helping stakeholders gather consistent data for performance comparison.
LM 80 focuses on two key performance aspects: luminous degradation and color shift.
Luminous degradation, also known as luminous flux depreciation, refers to the gradual reduction in brightness of LEDs over time. You may have noticed that LEDs become dimmer with age—this change is more rapid at higher temperatures. That's why manufacturers pursue both LM 79 and LM 80 certifications before releasing a product to ensure reliability and compliance.
The second critical parameter is color shift, also known as chromatic shift. Over time, the color emitted by LEDs can subtly change, impacting product consistency and user experience. LM 80 helps assess and limit this variation by enforcing high-quality standards.
In summary, LM 80 certification is crucial for delivering durable, high-quality, and internationally market-ready LED products.
