PROGRESS OF LIGHTING SOURCE

  • Early years of runway lighting were accomplished with Incandescent lamps with

filter for color

  • Then came quarts lamps
  • Longer lamp life but still using filters for color
  • More control of focus
  • Today the industry is moving towards LED
  • Longer Lamp life
  • Truer color quality at all levels of intensity
  • Cost of fixtures

SCIENCE OF PHOTOMETRIC

  • Color
  • Configuration
  • Candela
  • Coverage

PAST PHOTOMETRIC TESTING AT SLC

  • New construction commissioning
  • Annual testing
  • Run to fail
  • Rebuild fixture without photometric testing
  • Reinstall of fixture in the field and run to fail

TODAYS TESTING

  • Post Construction Commissioning
  • Summer months we test monthly
  • Weather affects
  • Chemicals
  • Need for cleaning

BENCH TEST OF ALL NEW AND REBUILT FIXTURES

  • Lessons learned
  • Prisms have become the new “weak link” in fixture

performance

  • Lamp focusing problems
  • Prism and Light source alignment
  • New fixture Testing

AIRFIELD TESTING LESSONS LEARNED

  • New fixture do not always meet standards
  • New fixtures can develop problems at initial running
  • New fixtures are not always assembled correctly from the

manufacturer

  • Fixtures can be installed too high and too low
  • Azimuth or plumb incorrect
