But in the long run, they may make up it in ecletricity consumption for its much longer lifespan.
LED lighting represents the latest development in the lighting industry. It has many advatages such as,A long lifespan, energy efficiency, impoved environmental performance, the ability to operate in cold conditions, not heat or UV emissions, deisgn flexibility, instant lighting and ability to withstand frquent switching, low voltage operateion, dimming capabilities, directionality, and etc.
