LED Lifespan,Generally speaking, is more than 50,000 hours, and some LED Manufacturers claim that the LED could operate 100,000 hours. The LED Lifespan is not simply defined in stop operating only, its lifespan could not be calculated by the measure of traditoinal lighting. In fact, When the LED items is tested, no one will stay and wait for the LED until stop working. However, There are still other ways to measure the spanlife of the LED. The reason why the LED could last long time is that the LED will not have the filament fuse problems. 

Many customers think LED will stop operating once the lifespan is up to 50,000 hours.LED will not directly stop the operation, but as time goes by, it will gradually degraded. As according to indication shown, the High quality LED items will still continue to operate, The  LED keep more than 60% of the initial light levels. In other words, the LED items reach its rated life and it may still is luminnous, just the light is weaker than before. The thermal energy is the main reason of LED Stop working. the LED Lifespan has something to do with the LED chip and LED driver. and we will talk about it in the future.
