LEDline®'s guidance lighting installation still looks great!

LEDline® guidance was first installed at Vancouver International in Fall 2009. The picture below, by Stewart McIntire, 30 January 2010
The following Six (6) x pictures below, were taken by Mr. Tim Holtz, Vancouver International's Chief Electrician for Airfield Lighting, 30 July 2019
LEDline® was Installed in Fall 2009; The following 6 x pictures are from the 30th of July 2019, Copyright Tim Holtz Vancouver International's Airfield Lighting Supervisor. After some +14 years, (January 2024) of continuous use, the installation here still looks like new, even when the LEDline® grooves and installation cross from concrete pads to asphalt and back again. Even though the grooves are cut in all directions, there are no degradation, spalling, or cracks in the concrete pads or asphalt, At Vancouver, the LEDline® guidance lighting has never been turned off, yet the LEDline® and its LEDs are still visible in bright sunlight.
From the enclosed 2019 pictures, Copyright Mr. Tim Holtz, none of the sawcut grooves in either the concrete pads or asphalt has had any damage done to them by LEDline®'s installation. Indeed, despite selecting the most prone areas to photograph, small off angles, edges etc., the installation still looks like new.

why Vancouver international's de-icing pads are excellent testing grounds for any in-pavement installations:

Vancouver International is North of the USA on the Pacific coast, so Vancouver is a major departure airport for all traveling to Asia and the Pacific. As such, being A MAJOR HUB, ESPECIALLY FOR ALL OF THE "HEAVIES" TYPE OF AIRCRAFT, the LEDLINE® there; + has survived the heaviest of aircraft traveling on it. + Has experiences winter SNOWPLOUGHS AND AIRFIELD RUNWAY/TAXIWAY DE-ICING BRUSHES; + BEING NEXT TO THE PACIFIC OCEAN, IT AND ITS INSTALLATION HAVE SURVIVED MANY/FREQUENT FREEZE/THAW CYCLES, yet it still looks like new; + Is close to major active Tectonic plates and fault lines, "The Pacific Ring of Fire" and so the the area averages some 500 earth tremors a year, yet the LEDLINE® is unaffected! + HAS SURVIVED MANY YEARS OF CHEMICALLY AGGRESSIVE DE-ICING PAD CHEMICALS; + IS EXPERIENCING INCREASING SUMMER HEAT! + After never having been turned off since its installation in the fall of 2009, some +14 years and counting, THE LEDLINE® there, and its installation has not been affected and is still in operation and use.
