Single Face LED Airport Guidance Sign Boards

Item Code : SE–AGS–LED–1F

Features

• Designed and developed as per ICAO Annex 14 and FAA Standards.
• Virtually eliminates runway shutdowns due to LED light source.
• Direct replacement for existing sign.
• Creates a highly uniform distribution of light, eliminating hot spots and shadows.
• Operates on ferroresonant or thyristor CCRs that are designed in compliance with FAA  / ICAO-ANNEX-14 requirements.
• Operates on 3-step, 5-step and 6.6A series circuits.
• Eliminates re-lamping expenses and reduces on-going maintenance costs.
• Improved safety — low, regulated DC voltage inside sign.
• Sign lumen maintenance of 70% (L70) minimum for greater than 5 years (assuming sign operates an average of 12 hours per day)
