power transmission tower, power line markersQ. What is obstruction warning light?
Ans. A light indicating the presence of an object which is dangerous to an aircraft in flight. The obstruction light is to be mounted at the highest point of the wind cone assembly to avoid being obscured by any other part when viewed from above.

Q. "Why do tall towers and buildings have marker lights on them?"
Ans. So that aircraft can avoid them "Any temporary or permanent structure, including all appurtenances, that exceeds an overall height of 200 feet (61m) above ground level (AGL) or exceeds any obstruction standard contained in 14 CFR part 77, should normally be marked and/or lighted."

Q. "What are the regulations detailing what kind of lights these are?"
Ans. The regulations regarding placement, colors to be used etc are Complex because various flashes per minute are required:

ICAO (Specification on the lighting and painting of structures can be found in ICAO Annex 14 Vol. I chapter 6 and Annex 14 Vol. I APPENDIX 6)

Q. "What is the required wattage, of these lights?"
Ans. Technical specifications regarding the actual lights are contained in
ICAO; International Civil Aviation Organization (www.icao.org)

Q. What is covered by your warranty?
Ans. The warranty given as standard ensures the performance of the light meets the required specification for the entire 5 year period.

Q. How does one know when an LED product is out of photometric specifications?
Ans. Our warranty allows for a minimum of 5 years of operation while ensuring the beacon meets the FAA's minimum photometric requirements. LED's do not "burn out" similar to incandescent. An LED will have a slight degradation of light output with use. This is similar to the degradation of a strobe tube.

Q. How many LED's can be burned out before one is out of spec?
Ans. According to the FAA's addendum, all LED based fixtures approved by the FAA are required to meet the minimum photometric's with up to 25% of the LED's not contributing to the photometric's of the fixture. After 25% the fixture shall cease to operate.

Q. How will the units withstand a lightning strike?
Ans. Depends on the intensity level of the strike. Each unit has a significant level of protection. Please see our manual for specific information.

Q. What are the true cost savings if we currently replace our lamps every year; every two years?
Ans. This depends on your current material & overhead costs as well as what you pay per kwh.

Q. What are your products certified to meet?
Ans. Our products are certified to meet the ICAO.

Q. Can rain, snow or other contaminants enter into the beacon and adversely affect the performance of the LED's or the fixture?
Ans. No, uses high performance O-Rings and other seals to prevent the intrusion of moisture and airborne contaminants into critical areas. The power supplies are hermetically potted for the same reason. The beacon has been designed for the application in which it is exposed to the environment.

Q. How will the units withstand a lightning strike?
Ans. Depends on the intensity level of the strike. Each unit has a significant level of protection. Please see our manual for specific information. The Beacon incorporates protection against voltage surges (as induced by nearby lightning strikes) and initiates a shutdown sequence in the event of a failure of one of the two LED lamps.

MOVs are incorporated into the design to limit voltage spikes in excess of 250V at current levels of 12,000 amps. Contact Dialight if additional protection is required or deemed necessary.

Q. What type of environmental testing has been completed?
Ans. The LED beacon has been tested and qualified in accordance with current FAA requirements. Please refer to Advisory Circular 150/5345-43E for specific testing procedures.
