How to assess the lumen maintenance rate of LED products is an important parameter to determine the quality of products, and is also an important indicator to distinguish the quality of light sources. The importance of LM80 to LED products is self-evident. So, how to judge whether a LM-80 report is qualified or not? In this regard, There are several points that are worthy of attention: 1, The luminous attenuation percentage and attenuation curve of the test product. 2, The color drift of the test product, that is, the color difference between 6000 hours and 0 hours.
Secondly, it is also worth noting whether the LM-80 reports has authorization, whether it meets the standard of test requirements, whether the sample quantity meets the requirements of the finished product energy efficiency certification, whether the color difference meets the standard requirements, whether the percentage of attenuation and its estimated life can meet the requirements.
