WRTL Arc 90 Lantern Installations
The WRTL Arc 90 is the larger version of the WRTL Arc. It was designed for a minimum lamp-wattage of 150W. Due to this, it can most-commonly be sighted along main roads and motorways. With it's distinctive shape, it was one of the most recognizable lanterns on British Roads until the LED replacement schemes (not to be confused with it's smaller cousin, the Arc 80).
