The Delhi Metro Rail Corporation (DMRC) has said it has started replacing conventional lighting in its stations such as incandescent bulbs and florescent lamps with LED lights to save energy.  According to the officials' statement on Sunday, the plan is to save energy and to provide a better experience. This is being done as part of a massive drive initiated earlier this year, and around one lakh LED lights have been installed by replacing old ones in the recent months, they said.

The Delhi Metro Rail Corporation has already covered 75 percent of the drive-in recent months by installing around one lakh LED lights at these locations by replacing the conventional lights, a senior official said. "To save energy and provide a much better lighting experience, Delhi Metro has undertaken a massive drive to replace the conventional existing lights (incandescent bulbs, fluorescent lamps, CFL lamps etc.) with LED lights at 155 locations covering metro stations, depots, parking, etc. which were constructed or opened for public under DMRC's Ph-I (2005) and Ph-II (2010)," the DMRC statement reads.

The LED-based light system will help DMRC save around half of the energy expenditure vis-a-vis the existing lighting system.  The lifespan of an LED system is longer compared to conventional existing lights, with much-reduced maintenance cost. On an average, an LED system lasts 50,000 operating hours or more, it said.
