LEDline® and Vancouver De-icing Pads

LEDline® safety guidance lighting was installed at Vancouver International's De-icing Pads, Fall 2009: 

 August 2026, the LEDline® has never/ever been turned off.

the  LEDline® installation still looks great, as does the LEDline® safety/guidance lighting, after being lit and left constantly on for some +16 Years and counting!

LEDline®'s guidance lighting installation 
still looks great! 

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 +10 years of continuous use, even with the small segments, the installation there still looked like new. This is true, 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, and the pictures were taken of areas where, if there were any spalling they would lightly occure; there was no concrtete degradation, spalling, or cracks of the concrete pads or asphalt.

Here, after some 10 years, the Vancouver LEDline® guidance lighting has never been turned off, 
yet the  LEDline® and its LEDs are still visible in bright sunlight.

LEDline® was first installed in fall 2009. The enclosed 2019 photos of the installation (copyright Mr. Tim Holtz, Vancouver’s Airfield Lighting Engineer) show that neither the concrete pads nor the asphalt has been damaged by cargo heavy aircraft, frequent winter freeze-thaw cycles, the roughly 500 earth tremors Vancouver experiences each year, or the LEDline® installation itself. Even in the areas most likely to show damage—small off-angles, edges, and concrete/asphalt transitions—the installation still looks new. 

Vancouver international's de-icing pads 
are excellent testing grounds:

VANCOUVER INTERNATIONAL AIRPORT, ON CANADA’S PACIFIC COAST, IS A MAJOR DEPARTURE HUB FOR PASSENGER AND CARGO TRAFFIC TO AND FROM ASIA AND THE PACIFIC, ESPECIALLY HEAVY CARGO AIRCRAFT. THE LEDLINE® INSTALLATION THERE HAS ENDURED:+ REPEATED TRAFFIC FROM THE HEAVIEST AIRCRAFT;

+ WINTER SNOWPLOUGHS AND RUNWAY/TAXIWAY DE-ICING BRUSHES;

+ FREQUENT FREEZE-THAW CYCLES NEAR THE PACIFIC OCEAN, WHILE STILL LOOKING EXCELLENT;

+ MOVEMENT OF CONCRETE SLABS CAUSED BY VANCOUVER INTERNATIONAL AIRPORT’S LOCATION ON THE FRASER RIVER 
   DELTA, WHERE WATER IS OFTEN PRESENT BENEATH THE SLABS;

+ PROXIMITY TO ACTIVE TECTONIC PLATES AND FAULT LINES IN THE PACIFIC RING OF FIRE, WHERE THE AREA AVERAGES
   ABOUT 500 EARTH TREMORS PER YEAR, WITHOUT AFFECTING LEDLINE®;

+ YEARS OF CHEMICALLY AGGRESSIVE DE-ICING FLUIDS ON THE DE-ICING PADS DURING WINTER;

+ while it still continuously REMAINS SWITCHED on, INCREASING SUMMER HEAT; 

+ SINCE ITS INSTALLATION IN FALL 2009, LEDLINE® HAS REMAINED CONTINUOUSLY ON AND OPERATIONAL 24/7 FOR MORE
   THAN 16 YEARS. DESPITE VANCOUVER’S DEMANDING CONDITIONS, THE LEDLINE® SYSTEM AND ITS INSTALLATION
   REMAIN UNAFFECTED AND OPERATIONAL AS OF AUGUST 2026.
