Abstract
In this paper, We has been studied the lifetime degradation of LED lighting system compared to MH lighting. Especially the effect of temperature level on the lifetime degradation has been investigated. The results show that temperature plays a role in the lifetime degradation and slope of degradation line represent as temperature level differently. However, It is possible to estimate the lifetime of LED lighting system using equation induced the slope of degradation line.
