THE FIRST & FINEST NVG FRIENDLY LED OBSTRUCTION LIGHTS
NVG Friendly L-864 Obstruction Light
Farlight developed the first NVG Friendly LED L-864 Beacon on the market. The NV-L864LED is a compact and efficient obstruction lighting solution.
NVG Friendly L-810 Obstruction Light
The NV-L810LED has all the benefits of our basic LED L-810 obstruction light, with the added benefit of being visible to pilots using night vision goggles.
Farlight also offers obstruction lighting accessories including alarmed controllers, flashers, and FAA photocells.
If you're not sure which obstruction light is needed for your application, or if you have questions about the proper placement of obstruction lighting, please review the FAA's Advisory Circular on Obstruction Light Regulations. International customers should review the ICAO Annex 14, which contains standards used in Europe and many other countries.
General Guidelines for Obstruction Lighting
All temporary or permanent structures that exceed an overall height of 200 feet (61m) above ground level (AGL) should normally be marked and/or lighted.
Normally outside commercial lighting is not considered sufficient reason to omit recommended marking and/or lighting.
Specific recommendations on the use of obstruction lighting can vary depending on terrain features, weather patterns, air traffic patterns, and geographic location.
OBSTRUCTION LIGHTING GENERALLY FALLS INTO THREE CATEGORIES:
Aviation Red Obstruction Lights
Red obstruction lights are used to increase conspicuity during nighttime. Daytime and twilight marking (paint) is required. The red obstruction lighting system is composed of flashing omnidirectional beacons (L-864) and/or steady burning (L-810) lights. When one or more levels is comprised of flashing beacon lighting, the lights should flash simultaneously.
Medium Intensity Flashing White Obstruction Lights
Medium intensity flashing white obstruction lights may be used during daytime and twilight with automatically selected reduced intensity for nighttime operation.
When this system is used on structures 500 feet (153m) AGL or less in height, other methods of marking and lighting the structure may be omitted.
These systems are not normally recommended on structures 200 feet (61m) AGL or less as the flashing white lights at nighttime may annoy local communities. When a structure is located in an urban area where there are numerous other white lights (e.g., streetlights, etc.) red obstruction lights with painting or a medium intensity dual system is recommended.
Medium Intensity Dual Red / White Obstruction Lights
Dual systems consist of Red Medium Intensity Lights for nighttime and White Medium Intensity flashing lights for daytime and twilight.
The primary advantage of a dual lighting system on structures 500 feet (153m) or less, is that painting of the tower is not required.
