How Airports Swapped To LED FAA Lighting

By Helen Nelson


In December 2017, George W. Bush signed a law that helped push light bulb efficiency. After this law was implemented, many establishments and business in the States collectively switched to LED lights because they are known to be more energy efficient. Airports, in particular, experienced some challenges while making the swap. Slowly, they managed to adopt LED FAA lighting to comply with the stipulations stated in the law.

Light emitting diodes are much better than other lighting systems in many aspects. Incandescent bulbs expend more warmth than energy, while LEDs do the exact opposite. They produce more energy and reduced heat. They also last longer than most other types of lighting.

According to research, LED lasts forty times longer than incandescent bulbs or about a whopping fifty thousand to one hundred thousand operating hours. This means fewer replacements, decreased manual labor, and increased savings in the long run. Because LED emits much less heat, they are also the safer option rather than incandescent bulbs.

They can operate on low voltage electricity, making them better at adapting to power concerns. They are also flexible with a range of other functions made possible by their relatively small size. Although in spite of its benefits, more people still opt for inefficient incandescent lights instead of LEDs which are better in various ways.

One primary motivator for this is the fact that incandescents are much cheaper in the initial purchase and LED prices commonly begin at twenty dollars apiece. What most people fail to realize is that electrical costs are considerably lessened in the long term when they opt for light emitting diodes since they can run smoothly on low voltage. Moreover, fewer replacements mean fewer purchases and fewer expenditures. As an added bonus, LEDs are even brighter than other systems.

Even airports are slowly adjusting to the switch to help the environment. However, airport personnel and pilots have also run into some issues with the switch, especially since the concern was a relatively new issue for them. The switch mostly began with runways and obstruction lighting.

What they failed to take into account was the increased brightness of the new lighting systems. The brightness had caused visibility problems for the pilots who made their landings on the runways. The intensity of the light emitting diodes, even on the lowest setting, simply could not match the rest of the lighting systems. This considerably impaired the perception of the pilots and effectively blinded them during touchdown.

As a solution to the initial complaints, the FAA introduced a solution for better command of the brightness setting of the lights. Instead of three, they installed five step regulators that allowed personnel to have increased control of the light settings. Along with inputs from the pilots themselves, the adjustments were made in order to guarantee 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.
