So through rigorous consider

 So through rigorous consider the power of design is completely up to 50,000 hours, so as to ensure the whole lamp life of 50,000 hours, and the light decay control in less than 30%.

3, some people say that the LED light failure, some people say that the small LED light failure, whether or LED light source as lighting?

LED Downlights A: mainly white as the lighting with LED main programs of most manufacturers plus yellow phosphor with a blue die, the light fades mainly depends on three factors, the manufacturing level of the LED die; b, phosphor LED Strip Lights quality; c, whether the lighting design lamps lit keep the junction temperature below 100 degrees, making the phosphor does not fail. Test tubes produced in Taiwan LED lighting for some lighting manufacturers junction temperature at 140 to 150 degrees, the lamp is lit, these lamps less than 5000 small-time decline of more than 60%, this lamp because the light fades too big, you can not use.
