PMC installs 28K LED street lights to cut down on bills

While Bharatiya Janata Party (BJP) and Shiv Sena fight over LED street lights in Mumbai, the Pune Municipal Corporation (PMC) has gone ahead and installed almost 28,000 such street lights in a bid to save electricity.

Despite chief minister Devendra Fadnavis’s order to carry out a survey of the lux (a unit of measurement of illuminance) of streetlights across the city with the help of IIT experts, PMC has decided to continue replacing conventional yellow sodium vapour lamps.

Starting 2010-11, the electrical department has replaced 28,000 street lights on internal roads across the city. There are 1.40 lakh street lights with 40,000 sodium lamps on all major roads. The corporation spends Rs 38 crore per annum on their maintenance.

Admitting that traditional lamps have more lux, Vijay Dahibhate, head of electrical department, said, “We have already decided to replace sodium lamps — that have 35 lux as compared to LEDs’ 20 — on internal roads.”

Even though the PMC has not calculated the exact savings after LED installations, they reckon that almost 30 per cent— nearlyRs10crore— willbesaved.

Shrikrishna Chaudhari, executive engineer of electrical department, said, “Though, sodium vapour lamps have higher lux level, energy saving is the major factor in LED. Fittings of both cost the same — Rs 8,000 to Rs 9,000. But sodium lights have a life of 12,000 hours whereas LED lights go up to 50,000 hours.”
