Kentucky Finishes Statewide LED Traffic Signal Retrofit

VALLEY VIEW, Ohio  (NYSE: GE)  An LED-for-incandescent traffic-signal lighting retrofit of nearly 3,000 intersections and nearly 500 school flashers, flashing beacons and advance-warning flashers on state-maintained routes throughout the Commonwealth of Kentucky has been completed, according to GELcore, LLC, maker of the estimated 77,000 RX11 high-visibility LED traffic signals installed during the five-month project.
Two organizations — the Kentucky Transportation Cabinet (KYTC) and the Finance and Administration Cabinet's Division of Contracting and Engineering — initiated the retrofit to reduce operational and energy consumption costs by as much as $3.2 million a year.
"This is one of many projects in the Transportation Cabinet's efforts to become more efficient and cost effective," notes acting Transportation Secretary Bill Nighbert. "Kentucky joins Delaware as the only states to use LED modules in all their traffic signals, school flashers and flashing beacons."
Many factors, including potential maintenance savings tied to the use of GELcore RX11 high-visibility LED traffic signals, motivated Kentucky officials to pursue a statewide initiative. Some points of interest:
  • The average life span of incandescent bulbs used in Kentucky traffic signals is 10-11 months.
  • The average life expectancy of the chosen GELcore solution is 8-10 years.
  • KYTC spent about $1.5 million in salaries and equipment usage annually replacing burned-out traffic signal bulbs.
  • With LED illuminated traffic signals, maintenance workers are less frequently exposed to potentially hazardous, high-traffic job sites.
"We see this as a best-practices maintenance- and energy-savings story," says Steve Briggs, vice president of marketing at GELcore. "This comprehensive installation of GELcore LED signals in Kentucky provides us with a platform for talking about the remarkable value of LEDs. We think government transportation officials throughout North America will take note."
