The Illuminating Engineering Society (IES) created the LM80 standard to quantify lumen maintenance and color shift in LED packages, arrays, and modules. It is a method for determining how the light output of an LED declines over time under controlled settings. LM80 testing normally entails running LEDs for a certain amount of time, usually 6,000 to 10,000 hours, and monitoring their light output and color shift at different temperatures. This data assists manufacturers and users in understanding the long-term performance of LED products.
Testing duration: LM80 tests are run over long periods of time, frequently thousands of hours, to simulate real-world operation. This provides information about how LEDs will perform over their estimated lifetime.
Lumen Maintenance: LM80 standard evaluates the percentage of an LED’s initial light output that remains after a given amount of time. This is critical for determining how long an LED can keep its brightness.
Color shift: LM80 also monitors how the color of the LED changes over time, which is useful in applications where color accuracy is vital.
Applications: LM80 reports are used to assess the quality and dependability of LED devices for a variety of purposes, including energy efficiency initiatives and product certification.
Importance: The LM80 is a useful tool for manufacturers and users to evaluate the long-term performance of LED goods and make educated decisions regarding their use.
