The answer to this question is yes, LED Lights do burn out but in a different way. As we know LED lights have a lifespan of approx 25,000 to 100,000 hours which mean If we used 12 hours a day, an LED Light will last more than 11 years!
But first, it is necessary to know the working of LED Lights.
We all do live in the misconception is that LED does not produce heat. As a matter of fact, they do create heat. When electrons move from one material to another through a semiconductor. But when the second material is energized, they can not accept them, so they must release their energy. Then this energy is dispelled it is on the form of photons i.e light rays which cause heat and visible lights. After some time, the semiconductor will lose its ability to exchange these electrons and that is the thing that causes LED lights to diminish and go out. In time they will lose the ability to exchange electrons, yet that is, in reality, more an instance of wearing out instead of burn out. But, the good news is it might take up to three decades for that to occur.
