An overview of LM 79 and LM 80 certification testing

Are you looking to get LM 79 and LM 80 certification for your product? Today every LED manufacturer, designer, and specifier looks to get LM 79 and LM 80 certification as it defines the performance and durability of the LED. Not to mention but in recent years, the LED lighting industry has seen a huge growth in demand. Due to that, the industry witnessed an increase in product effectiveness and a decrease in the cost of the LED lighting product. 

But still, the product effectiveness lacks in some aspects and needs an improvement in the performance and efficiency.  Some of the common challenges faced by industry like energy efficiency, colour shit, current droop, and more. All these not only damages the product and company reputation but customers are likely to purchase any of the products in the future. 

To tackle these challenges you need experts that can help you with getting LM 79 and LM 80 certification that highlights your product effectiveness and performance. EVTL India has helped businesses and manufacturers across the globe to get LM 79 and 80 certifications. Our professionals will help you to bring your LED lightning product to the market. Before we highlight why you need to hire us, let us help you with getting a clear understanding of what LM 79 and LM 80 are? Why do you need these certifications for your product?

What is LM 79? 

LM 79 is the electrical and photometric measurement of the solid-state lighting product.  It was introduced with a goal to define how the LED lamp or fixture performance needs to be measured. Mainly with the increase in the use and development of LED technology the need for standardised testing procedures for LED was needed more than ever. That is when LM 79 was launched. The measurement of the LED lamp or fixture is carried out either with the help of integrating the sphere or using a goniophotometer system. 

The test of any LED lamp or feature in accordance with the LM 79 is done at a single temperature at a point in time. That means it might offer you the performance of LED but does not offer any indication on how the performance would change over time in different temperatures. LM 79 is also called the IES LM-79-19 approved method. 

Why is LM 79 certification or approval needed more than ever?

If you are a manufacturer, vendor, specifier, or designer looking to sell your LED products in different markets across different countries then it is essential for you to get LM 79 approval. It allows you to identify the quality in the various playing fields and also helps you to evaluate various parameters. When it comes to testing then it is measured in two groups: electrical measurement and optical measurement. 

Where in the electrical measurement the data will include RMS AC voltage, AC active power, power factor, RMS AC current, voltage frequency, and more. Whereas in the optical measurement the data gathered during a photometric test involves Luminous efficacy, total luminous flux, chromaticity coordinates, colour rendering index, and many more. 

What is LM 80? 

LM 80 was introduced with a goal to measure lumen maintenance of LED lights like the arrays, packages, modules, and more at different temperatures. It is an IESNA (Illuminating Engineering Society of North America) approved standard that every LED manufacturer needs to highlight the performance and durability of the product. LM 80 is considered worldwide and will help you to launch your product in the international market with slight variations in the regulation depending on different countries. 

Why is getting LM 80 certification essential?

LM 80 certification or approval is needed for every designer, manufacturer, and specifier looking to launch their product in the Indian market or in the international market. With LM 80 one gets access to the standard of testing various LED products with a goal to obtain data that can be used for comparison. 

LM 8) focuses on measuring two essential aspects: luminous depreciation and colour shift. Not to mention but over time the luminous depreciation also known as luminous flux starts to decrease. Or you must have heard that LEDs started to get dimmer. The luminous depreciation of the light varies depending on the model of LED and temperature. At higher temperatures, the flux takes place more quickly than the lower temperature. That is the reason why manufacturers look for LM 79 and LM 80 approval before launching their product. 

The second measurement happens with the colour shift. Not to emotion but over time the colour emitted by LED changes. In the industry-specific term, it is called a chromatic shift. So the LM 80 focuses on measuring these two important aspects for LEDs to offer a better quality of the product.
