AIRFIELD LIGHTING 22 airportbusiness February/March 2018 "It was quite antiquated," he said. "I believe it was constructed around 1986." McIver said the airport put a precast structure in with lightening arrest equipment to protect the sensitive systems. The airport planned the next phase for the current fiscal year, which McIver said includes duct banks, a rotating beacon, guidance signs and LED equipment. Peru has issues with older wires, insulation issues, grounding issues and safety concerns with the electrical system breaking down. "Our final phase will be basically completed in 2020, which will consist of replacement of the runway edge lighting and markers of the perimeter of the runway pavement," McIver said. "Basically, our challenge with this project has been limited funding and keeping our lights on and the cost of electricity lower." McIver said the airport worked with NGC Corp. on its electrical costs. As they continue to rise, the airport looks for more efficient equipment. "We wanted to reduce electrical costs and do that through better technology involved with the LED and also make it safer," he said. "NGC Corp. is designing lightening arrestors at mul- tiple locations in case of electrical strikes. That will mean less replacements and longer lifetime bulbs with the LED." CHANGING APPROACH WITH LEDS Corey Stutz, marketing manager, for the Americas for ADB Safegate, said the switch from incandes- cent lights to LED lights on the airfield creates new challenges for airports when it comes to putting together a regular maintenance plan. Old lights would last about 500 hours, so almost every quarter airport maintenance staff would be replacing a bulb in a fixture. When LED lights are put into the airfield, the bulb replacement goes down, so other maintenance procedures like torqueing might get overlooked. "I'm talking about cleaning out the prism win- dows. I'm talking about doing photometric assess- ments, it's the torqueing of the light fixtures," Stutz said. "As airport lighting fixture sits in the field, they're getting hit by aircraft, especially in certain areas of touchdown zones GDC, centerline lights." Photometric testing can be contracted out, offering a cost effective alternative for airports keeping up with the condition of LED lighting. ADB Safegate
