The AGSB-L LED signs were designed specifically for the ICAO and Transport Canada markets. These LED signs virtually eliminate runway shutdowns due to the longevity of the LED light source. They are direct replacements for existing signs, and they create a highly uniform distribution of light, eliminating hots spots and shadows. They can be powered from either a ferroresonant or thyristor type CCR and operate on 3-step, 5-step and 5.5A series circuits.
