How Airports Swapped To LED FAA Lighting

The Energy Independence and Security Act signed by George Bush on December 2017 is a law that calls for light bulb efficiency. As a result of this, many establishments in the United States have collectively opted to use LED lights, which are more energy efficient. These establishments also include airports. Airports have slowly adopted LED FAA lighting as a means of complying with the rules stipulated in this law.

Although the law did not necessarily call for the complete ban of incandescent bulbs, LEDs are simply better in many other aspects. While incandescent bulbs release ninety percent heat and only ten percent energy, LEDs emit only minimal heat and more energy. They also last significantly longer than other sources.

Researches have stated that LEDs can actively operate between 50000 to 100000 hours. This is around forty times more than incandescent lights. With a longer lifespan comes long term benefits such as increased savings, less manual labor, and fewer replacements. Since they are less hot, they are also safer in comparison to other lighting systems, particularly incandescent lights.

They can function well on low voltage electrical systems, making them more secure in instances of power complications. They are also adaptable to several functions because of their significantly smaller size compared to others. Unfortunately, even if they are ultimately better for the environment, many people still prefer inefficient incandescent lights.

This is mainly because of the difference in price. Incandescents usually cost around one dollar, while light emitting diodes can rise up to twenty dollars per piece. What most people cannot acknowledge is that electrical bills are considerably reduced overall with light emitting diodes. This is due to the combination of enhanced ability and lifespan. With fewer replacements in between, expenses are reduced overall. Additionally, they are also brighter in comparison to other systems.

Airports have even adjusted to LEDs to help save the environment. The switch began with obstruction lighting and runways. This does not mean, however, that they did not encounter any issues during their first few trials with the new lights.

In fact, they encountered a number of issues. A surprising problem that they did not expect was the brightness intensity of the new LED lighting systems. This brightness caused visibility issues for pilots landing on the airstrip. The brightness of light emitting diodes could not match with the other systems, even on the dimmest setting. The increased illumination impaired the perception and vision of the pilots, blinding them whenever they landed for touchdowns.

In response to the complaints, the Federal Aviation Administration immediately provided a solution to dim the lights. By installing five step regulators, the personnel were able to have better control of the brightness level. Together with inputs from pilots, light adjustments were made to ensure safer landings.

At present, airports now have LEDs installed into jetways, tarmacs, hangars, and other places. The improvement and changes applied to the illuminating systems were made possible by noting down the initial issues that arose during the replacement. Passenger safety and visibility concerns were the primary issues that have since been solved. With these combined efforts, airports can generate much less energy than with incandescent systems. If anything, this proves that if airline companies can switch to eco friendlier solutions, we can too.
