3. Power Efficiency
LED Technology: Modern L 864 beacons use energy-efficient LEDs, reducing power consumption while maintaining high visibility.
Voltage Compatibility: Typically operates on 120-347V AC or 24V DC systems.
Regulatory Compliance
The L 864 beacon complies with major aviation lighting standards, including:
FAA AC 150/5345-43J (Specification for Obstruction Lighting Equipment)
ICAO Annex 14 (Aerodrome Design and Operations)
EN 12499 (European standards for aviation obstruction lighting)
These regulations ensure that the beacon meets required intensity, flash patterns, and durability for safe aviation operations.
Primary Applications
1. Obstruction Lighting for Towers and Structures
Used on communication towers, wind turbines, and tall buildings to warn aircraft of potential hazards.
Red beacons are common for nighttime use, while white strobes may be used during daytime.
2. Heliport and Airport Lighting
Installed on helipads and airport structures to mark obstacles and enhance navigation.
Often synchronized with other lighting systems for consistent visibility.
3. Offshore and Marine Installations
Essential for oil rigs, lighthouses, and offshore platforms where aviation activity occurs.
Must withstand harsh saltwater environments.
Installation and Maintenance Best Practices
Proper Mounting: Ensure the beacon is securely fixed and aligned for maximum visibility.
Regular Inspections: Check for lens cleanliness, electrical connections, and corrosion.
Synchronization: If multiple beacons are used, they should flash in unison to avoid confusion.
Backup Power: Consider uninterruptible power supplies (UPS) for critical installations.
Advantages Over Traditional Lighting
Longer Lifespan: LEDs last significantly longer than incandescent bulbs.
Lower Maintenance: Reduced need for frequent replacements.
Energy Efficiency: Consumes less power while maintaining high brightness.
The L 864 beacon is a vital component in aviation safety, ensuring that obstacles are clearly marked for pilots in all visibility conditions. Its compliance with FAA, ICAO, and EN standards makes it a trusted choice for airports, heliports, and tall structures worldwide. By following proper installation and maintenance protocols, operators can maximize the beacon’s effectiveness and contribute to safer skies.
