There're already many Town Councils in Singapore embark into replacing their tradition lighting to more cost efficient lighting such as LED (Lead Emitting Diode).
1) The tangible cost saving can be real attractive in a long term. With a very space constraint country like Singapore, it is really not possible to install solar cell in our home (purpose of energy conservation).
2) LED is an alternative. The installation is simple and the benefit is obvious to your monthly electrical bills.
