Cost-Benefit Analysis of Lighting Upgrades

While initional capital investment for LED conversion can be fasional ($5,000 - $15,000 per fixture including installation), thee long-term savings justify the extrasse. A medium- sized airport with 50 taxiway edge lights might expect:

  • Energy reduction: 60- 70% annual savings on electricity.
  • Maintenance labor: 80% fewer lamp changes per year.
  • Reduced extage durations: LED have a rated life of 50,000- 100,000 hour vs. 2,000- 4,000 for incandescents.
  • Improved on-time performance: Fewer taxi delays due to lighting-related confusion.
