Elmendorf Air Force Base, located in the state of Alaska, has placed an additional order for 70 units of Carmanah's Model A702 airfield lights. These solar-powered LED lights are to be used as taxiway and apron edge lights. This will bring the total number of Carmanah lights in use at this USAF base to over 300 units.
Elmendorf AFB, located at 62 degrees northern latitude in the state of Alaska, experiences 20 hours of darkness in the winter months along with temperatures dipping well below -20 degrees Celsius. These elements, combined with heavy snow, make for a challenging installation. In response to these harsh conditions, Carmanah employs its patented Automatic Light Control (ALC) function. ALC allows for a slightly reduced light intensity but more than doubles the autonomy of the lights (300 hours) during the winter months.
In addition, Carmanah A702 lights have vertically mounted solar panels that offer the best solution for solar charging during the winter months, when the sun typically only rises a few degrees above the horizon.
In December 2002, Elmendorf AFB was the first USAF base to install Carmanah solar LED airfield lights. Their initial order of A601 taxiway lights were installed on a trial basis and performed exceptionally well over their first winter. Since then, more than 12,000 Carmanah lights have been deployed with the US Armed Forces and Coalition Forces at 100 Air Bases around the world.
