“LEDs do not contain the toxic element mercury, unlike compact fluorescent and mercury vapour lamps,” the official said. Brass Pump fitting LED lighting emits white light, which provides clear visibility that results in better public satisfaction,” an official in KMC’s lighting department said.The operating and maintenance cost of a LED fitting is very minimum compared to conventional HPSV fitting. The added areas in the city, including a major portion of the Eastern Metropolitan Bypass, has tube lights.
“We will replace these tube lights with sodium and metal lights initially and with availability of funds, we will gradually replace them with LED’s. The White LEDs’ that we are using in street light fittings are very energy efficient and consumes nearly 50 per cent less energy than that of conventional HPSV fitting.The high pressure sodium vapor lamp fittings (HPSV) or Metal Halide Fittings consumes greater electricity and has huge carbon dioxide emissions, which is a major green house gas.
The state government is allocating Rs 40 crore to the KMC for this purpose.. There will not be any tube light for street lighting in the KMC area in future,” the official said, adding that in Rs 1 crore, as many as 400 sodium lights can be replaced with LEDs. “We pay an annual bill of Rs 12 crore for street lighting. The total annual bill of the KMC covering all its establishments is Rs 32 crore annually.Kolkata: The Kolkata Municipal Corporation (KMC) is gradually going to replace all sodium and metal lights in the city with white LED lights for cutting down electricity costs, saving on carbon emissions & utilisation of green energy.
LED fittings have a relatively long useful life of 50000- 75000 burning hours when compared to conventional HPSV or metal halide fitting which has a life time of 15000 burning hours roughly.The KMC will gradually move towards replacing all lights in its offices, including health units, schools, compactor stations, markets, borough offices, ward health units, pumping stations, crematoriums with LED. This will come down by at least Rs 4 crore.The KMC has also made a plan of putting sodium and metal lights into use after replacement
