GELcore Improves Color and Intensity Uniformity in New Incandescent-Look LED Traffic Signal

VALLEY VIEW, Ohio  (NYSE: GE)  New GT1™ 8-inch (200mm) and 12-inch (300mm) full-ball LED traffic signals from GELcore, LLC, give traffic management professionals throughout North America, GE-quality, incandescent-like LED solutions that are both keyed to new specifications of the Institute of Transportation Engineers (ITE) and outfitted with unique, performance-enhancing attributes:
  • The GELcore-designed optical lens system precisely controls light collection and distribution to produce a tight color uniformity (+/- 3 nanometers) that meets the new ITE specifications.
  • Designed for both fixed- and span-wire applications, the flat design of the exclusive optical lens system uses the latest in high-brightness, high-power LED devices to deliver exceptionally consistent brightness and module readability with a luminous intensity uniformity that meets new ITE specifications.
  • Weatherproofed against blowing rain, high winds, and other sources of environmental stress, it uses radially compressed O-ring gaskets and over-molded electrical lug connectors to provide outstanding moisture and dust intrusion protection ratings that meet ITE specifications.
  • Improved failed-state impedance protection detects the loss of LED load to reduce the likelihood of a false reading by traffic control equipment, and meet new ITE specifications.
Thanks to strides GELcore has taken in the area of thermal management and the company's commitment to the customer-focused Six Sigma design process, highly energy-efficient GT1™ traffic signals are optimized for the longest possible average rated life. Designed for direct retrofits and easy maintenance with a field replaceable front lens free of optics, the GT1 is available with red, yellow or green LED light engines, and clear or tinted lenses.
GT1 signals are designed around the new ITE specifications, CSA-approved and available as ENERGY STAR®-rated solutions. Using MIL Std 810 for environmental robustness, GT1 passed rigorous reliability and qualification testing, including high-temperature and high-humidity cycling. Each GT1 module is backed by a 5-year limited warranty.
