India-based firm GMR Hyderabad International Airport (GHIAL) has upgraded the entire airfield ground lighting (AGL) signage at Rajiv Gandhi International Airport (RGIA) from compact fluorescent lamps (CFLs) to light-emitting diode lamps (LEDs).

AGL signage is installed to guide pilots in spotting their aircraft location at the airside, as well as during taxiing to the designated areas.

“With LEDs offering approximately 50,000 running hours of lifespan, the conversion is estimated to save almost 45% of the energy that is used by standard lights.”

Over two weeks, a total of 132 units of AGL signage occupying 1,700 acres of the airside were converted and more than 350 LED strips of 10MW have been retrofitted to the signage.

With LEDs offering approximately 50,000 running hours of lifespan, the conversion is estimated to save almost 45% of the energy that is used by standard lights.

This energy conservation minimises the dependence on conventional non-renewable energy sources, which in turn cuts down greenhouse gas emission, leading to a decrease of more than 20,000kg of CO2 per year.

GHIAL CEO SGK Kishore was quoted by media sources as saying: “We are fast approaching to turn RGIA into a 100% LED Airport. Conversion of AGL signage into LED is one such firm step towards this commitment.
