Although LEDs do experience a gradual and permanent reduction in light output during their normal operating life - caused either by a reduction in the light-generating efficiency of the LED die, or a reduction of the optical path within the LED package - the Dialight street LEDs are expected to provide about 70 per cent of their original light output after 50,000 hours or 10 years, provided that they are not overdriven.

在正常操作下，LED必需要经历光输出逐渐减少的过程，而这个过程是会一直持续着的。导致光输出减少的原因可能是由于LED产生光的效率在降低，或者是由于LED压缩包内的光径在减少。不过，只要没有超负荷使用，Dialigh的LED路灯在工作50，000小时或10年后，还可以达到70%原始光输出的能力。
