One of the major initiatives taken by Greater Chennai Corporation under Smart City Project is replacing of existing Sodium Vapour lamps with LED lights. LED based lighting system has become a popular substitute for low voltage brighter lighting. LEDs are favored over incandescent bulb or CFL as LEDs convert far more of their energy into light. For instance, substantial amount of energy is wasted as heat in bulbs. Increased efficiency means a drop in withdrawal from the grid or the batteries will last much longer maintaining the brightness. The expected lifetime of LEDs is over 10 lakh running hours. To top it all, the maintenance cost is negligible, as it operates at a very low voltage.
Greater Chennai Corporation has successfully delivered the job as promised. The project has been completed successfully & currently the maintenance period is underway.
