LED lamp life than incandescent and fluorescent lamps or xenon lamps much longer. LED lamp life is typically 50,000 to 100,000 hours. With the use of time, long time, LED lights use the flux becomes small and will not be completely scrapped. The smaller flux is called "bad light", a LED lamp can be used time (working hours) run out of bad calculations.
Industry standard to assess the life of LED lamp LED light source is 30% of the light decay time as an evaluation point. 100,000 hours lamp life is not equal to one. LED lamp life is rated 30% when the lumen when the scrap. More than 10 hours of LED light source will work, but the flux will be reduced.
