The Rajiv Gandhi International Airport at Hyderabad has been upgraded with energy-efficient LED signage. The switch from conventional halogen lighting system is expected to help save one lakh units of electricity every year and curb emissions of 81,000 kg of carbon dioxide.
Airfield Ground Lighting Signage acts as a guidance signpost to help pilots identify the location of their aircraft both on the air-side and while taxing to the designated areas. LEDs are known to be highly energy efficient with a life span of more than 50,000 running hours and 90 percent less power consumption than incandescent bulbs – reducing power cost and energy.
The airport has recently converted its taxiway edge lights from conventional lamps to LED, becoming the first airport in south India to achieve this feat. The entire landside of the airport has also been fitted with LEDs. Officials say that the airport has been moving away from non-renewable sources of energy and is eager to reduce 20,000 kg of CO2 per annum.
