Medium- and low-intensity edge lights are used for runways, taxiways and heliport applications. Fixtures are available in 6.6 A series circuit and 120 VAC parallel circuit configurations. 6.6 A series circuit fixtures are available in standard incandescent T10P and quartz PK30d styles. The fixture has a very robust and durable design. It uses standard medium intensity lenses, gaskets, sockets and fixture cable assemblies, allowing for spares interchangeability with competitor's fixtures. The Edge Light Marker provides superior day or night visibility of edge light location for snow removal or other maintenance operations. It's available with optional high grade retro-reflective bands to greatly increase night time visibility.
