Two different standards for general LED tube lighting

LED lamp life is very long. Like other light bulbs, LED tubes will be time to gradually reduce the light output. But unlike other bulbs, LED bulbs will gradually turn darker and burned directly, not like any other bulb which will be suddenly broken. Inappropriate temperature, power and water vapor is the main cause to destroy the LED and determine the LED life factors.

IES another manual guide about LED light source and module --LUMENS-80-08 Measuring Lumen Maintenance of LED Light Sources specifically develop a detection LED life of the program. (and the light dimmed to how much the phase-out).

LED life is decided by the power of the number of passes a certain threshold number of hours, which is also known as lumen maintenance.

LM-80-08 manual referred to two different standards adopted by the industry, a requirement of bulb lumen less than 70% of the original is not suitable to continue to use. And the other provisions of the lumen which is lower than the original 50% will be no longer used. The first standard (L70) is adopted to general lighting LED lamps for home, while the second standard (L50) is used a decorative LED lighting. Both LED life standards developed by the LightingResearchCenter of the solid-state lighting systems and Technology Alliance Team (ASSIST).

For example, a LM-80-08 Detection of LED lamps for home and claimed more than 30,000 hours, the number of lumens is still higher than 70% of the original light output by the detection of the LED samples. Which means that passing LM 80 is not only reached the basic light fades requirements, but also even better performance. LED panel lights inside pointed that the cost of the LM80 test project is much high, nearly about 15,000 dollars. The reason is that it should light up thousands of hours to do the light fades test parameters and precise information. The manufacturers who can afford to do this are generally medium-sized and large companies.

The new product detected by LM-80 is helpful, but it will take a longer time to do the detection because the integrity of the testing process needs to spend 6,000 hours. That is the reason why the test price of LM80 is so high.
