FAA Obstruction Lighting

FAA Obstruction Lighting

Carolina Microwave Associates, Inc. offers FAA-approved obstruction lighting kits. The FAA approves lighting specifically for making obstructions visible. Generally, any structure over 190 feet is required to have obstruction lighting. The FAA defines five categories of obstruction lighting, A- F.

For the complete FAA Obstruction Lighting Rules, please download the FAA Circular. If you have any questions, please call us at 888-684-6248 or contact us. We look forward to working with you.

FAA's five categories are below. If you're not sure which one applies to your project, feel free to contact us (or by phone 888-684-6248) for assistance.

"A" Series Obstruction Lights:

Red (L-864) obstruction lights are used to increase conspicuity during nighttime. Daytime and twilight marking is required. Recommendations on lighting structures can vary depending on terrain features, weather patterns, geographic location, and in the case of wind turbines, number of structures and overall layout of design. Typical obstruction heights vary between 20 to 2200 feet.

"D" Series Obstruction Lights:

Medium intensity flashing white (L-865) obstruction lights may provide conspicuity both day and night. Recommendations on lighting structures can vary depending on terrain features, weather patterns, geographic location, and in the case of wind turbines, number of structures and overall layout of design. Typical obstruction heights vary between 200 to 500 feet.

"E" Series Obstruction Lights:

Medium intensity flashing white (L-865) obstruction lights may provide conspicuity both day and night. Recommendations on lighting structures can vary depending on terrain features, weather patterns, geographic location, and in the case of wind turbines, number of structures and overall layout of design.

"B" Series Obstruction Lights:

Lighting with high intensity (L-856) flashing white obstruction lights provides the highest degree of conspicuity both day and night. Recommendations on lighting structures can vary depending on terrain features, weather patterns, geographic location, and in the case of wind turbines, number of structures and overall layout of design.

"C" Series Obstruction Lights:

When a structure lighted by a high intensity flashing light system is topped with an antenna or similar appurtenance exceeding 40 feet (12m) in height, a medium intensity flashing white light (L-865) should be placed within 40 feet (12m) from the tip of the appurtenance. This light should operate 24 hours a day and flash simultaneously with the rest of the lighting system.

"F" Series Obstruction Lights:

This dual lighting system includes red lights (L-864) for nighttime and high intensity flashing white lights (L-856) for daytime and twilight use. This lighting system may be used in lieu of operating a flashing white lighting system at night. There may be some populated areas where the use of high intensity lights at night may cause significant environmental concerns and complaints.

Don't get hooked on a particular technology, just because it's the latest or the most energy-efficient or (insert reason here). There is no ideal lighting technology. Each has its particular advantages and drawbacks. That's one reason we offer red incandescent along with LED.

Many people are hooked on LED, because it's far more energy-efficient than incandescent. In other words, it throws off much less of the energy as heat. Is that the kind of lighting you want on the exterior of an obstruction that is prone to freezing over with thick ice or even snow? Absolutely not. On the other hand, if you have an obstruction that's facing west and you're in Florida then the application is entirely different.

Or consider the choice between medium intensity and high intensity strobe lights. Which one you go with depends on what you're trying to accomplish.

Not sure what you need to do? No problem. We have experts who can help. Feel free to contact us (or by phone 888-684-6248) for more information.

You'll want to start with the FAA circular that provides the FAA Obstruction Lighting Rules.

Applicable standards for design and installation include NFPA 70 (the National Electrical Code) and standards produced by the IES (Illuminating Engineering Society of North America).
