How long does your LED continue to glow?

Hey, everyone has an interesting test to share with me today. I tested the wooden 6000 for one year. For different LED grow lights, please see how much light output has decreased during this period. I don't think this is the result of the four lights I tested last year. They are here. You already own Mars Hydro Cobbmicro 100, the previous generation Ggeneration 3, the cold corn planting manual and the garden lighting group HL g QB 2 8 8 v2. They are in the same environment. Yes, so 6,000 hours is almost half, if you spend a whole year allocating vegetables and flowers, then you might do something between 5,000 and 6,000 hours, so it has grown for at least a year, and I have been In observation, the power output was tested after 6,000 hours and compared with the original results obtained when we performed the original test. These original tests are all in the article, and you can view the test settings and the conditions of the test results. Compared with the original test results, this is interesting, but not exactly the same as I expected. We expect that the LED lights may continue to use 50 tires, and there will be errors for about seven to eight years, but what we really want to know is when they need to be replaced based on the light output being reduced to a level worth changing, if you can As you can see in the figure, the results are different, but the average is about 5. If we look back at the operating temperature and then look at the 6,000-hour output power reduction percentage allocated for the past 12 months or 6,000 hours (between the cold spot around 4:00 and the hlg between about 7 o'clock). When the temperature on the radiator is very similar to the temperature between the Martian miniature on Mars and the ice book on the radiator, 42 degrees Celsius HLG is difficult to work at 130 watts. You can see that its opening temperature is about seven or eight degrees. Therefore, this shows that you know that the operating temperature is critical and will affect the service life or may affect the service life, so please pay attention to the drop in efficiency, so that the tilt angle still obtains the same power output for each lamp, but our efficiency is declining , So it still consumes the same amount of electricity after one year, but reduces the light output by 5% on average, which means that the service life is about our LED lights can shine well, about 80% of the original output, about four years. If you have been using it, or at least add some lights to supplement the original lighting level, you should consider replacing the lights after about four years. The sample size is small, each manufacturer has only one light source, none of them can not represent the exact number, and there will be some errors due to the small sample size, but hope this is a good indication that will help you understand the following facts: These facts do not mean that they will never last, but need to be replaced, and you know, no matter the model type or the manufacturer, they will depreciate a bit, yes, so one thing is that I did not find a lot of other information, such as real Test information, which contains hard data, and over time, it will aggregate links to similar tests or other people you know, please leave them below, I would love to see them, yes, it is It's very different now, hope you like to take care
