White Medium Intensity LED Flashing Obstruction Beacon
HORIZON™ 2000 DC Series

Home - What's New - Who We Are - Products - Request Quote - Search - Contact Us - Terms - Links

Compliance and Applications
FAA Type: L-865 Medium Intensity Lighting
ICAO Type: Type A Medium Intensity Obstacle Light
ETL Certified: FAA Advisory Circular 150/5345-43G
Compliant to: ICAO Annex 14, MIL-C-7989, DGAC of Mexico, CAR 621

The HORIZON White LED Medium Intensity Lighting System combines a daytime white LED light and a nighttime white LED light into a single flashhead. Its self-contained power supply, with available GPS sync and day/night sensor, simplifies wiring but also accepts external signals if desired. Advanced features include replaceable LED modules, cutting edge optics, individual LED monitoring/bypass, and active lightning protection (patent pending). The unit also monitors the system and provides a NO or NC alarm contact upon any system failure. An integrated WiFi is also available to provide real time data from the flashhead from up to 2 miles away via computer or hand held device.

Medium intensity obstruction lighting systems are typically used on structures between 150' (45M) and 500' (150M) above ground level to provide aviation safety. The use of a medium intensity white strobe during the daytime typically eliminates the need to paint the structure with aviation orange and white stripes. Medium intensity obstruction lights are designed for lighting tall structures such as communication, television and radio towers, chimneys, cooling towers, tall buildings, catenary river crossings and bridges.

• Original equipment manufacturer: One source for fixtures and complete lighting systems.
• Single flashhead construction: Compact design.
• Fail-safe redundancy: Automatic bypass of failed LEDs for continued operation.
• Wiring compatibility: Existing tower wiring can be used for retrofit applications, environmentally sealed connectors, fewest number of control wiring on the market.
• Interchangeable LED modules: Single screw access, built-in safety switch, fully field serviceable unit.
• Cutting edge optics design: Exclusively designed 'Eklipse' optics package, community friendly lighting system.
• Lightest flashhead: 17 lb., ease of handling and maintenance.
• DC Input: 48VDC

• Unit Weight: 17 lb. (7.7kg)
• Supply Voltage: 48VDC
• Average Power: 50 Watts Day, 25 Watts Night
• Operating Temperature: -40°C to +55°C (-40°F to +131°F)
