ADB - L-848YRLB LED Airfield Lighting - Description: Formerly Siemens – The L-858YRLB 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.
