LED technology offers important benefits over
conventional lighting technologies. LED efficiency is fast
surpassing that of conventional lighting technology. Energy
savings from 50 % to 70 % compared to conventional
technologies result in similar cut to carbon emissions [4].
Superior control over light color, intensity and direction
allows novel lighting system designs that can deliver a wide
range of social co-benefits. With this unique feature of
controllability, the total system energy savings can reach up
to 80 % [5]. Being such a promising technology, LED is still
facing barriers to completely penetrate in the society.
