It’s reported that the Trinamool Congress-led Kolkata Municipal Corporation authorities want to install LED lights across the city after the success of a pilot project to light up the city's streets.

The erstwhile Left Front board first decided to modernize streetlights on some major thoroughfares.

After assuming power, the Trinamool board decided to take up a pilot project by converting the streetlights at Kalighat temple, SN Banerjee Road, New Park Street and Syed Amir Ali Avenue. While the KMC lighting department shelled out Rs 66 lakh, the MNC paid Rs 60 lakh as a gesture.

In the second phase, KMC plans to introduce LED on Bidhan Sarani, Vivekananda Road, Amherst Street, Loudon Street, Camac Street, Bondel Road, Ballygunge Circular Road, Gurusaday Road and Alipore Road.

The LED's energy efficiency has wowed KMC officials. It saves at least 40% energy. According to an estimate, the KMC lighting department has to pay Rs 4 crore a month to CESC for lighting around 2 lakh streetlights. "LED lights will last longer. Going by an assurance from Philips international, the new lights will have an lifespan of 70,000 hours. This is more than double the lifespan of existing lights," said Manzar Iqbal, MMiC, lighting.

However, there still some problems to be settled ,such as the cost,the choosy installation of the LED on some of the major thoroughfares  as well　as the train for specialized employees.
