Does the service life of ceiling fan lamp have much to do with motor? Zeno ceiling fan lamp motor warranty 10 years, is it true?

Now the fan motor technology is very mature, and there are few so-called motor quality problems (except some black-hearted manufacturers). The problems of ceiling fan lamps are mostly due to improper installation or the service life of LED lamps. As long as the motor is selected better, there will be no big problem.

The motor used in this brand of ceiling fan lamp is pure copper motor with low power consumption and good quality. I checked the 3C certificate, which is in line with national standards, so as long as it is not damaged by external forces, it will be fine for ten or twenty years.

So 10 year warranty is basically a false proposition. Since it can't be broken, what is the difference between 10 and 20 years?
