Dialight provides LED signals for NYC subway system

Sept. 6, 2007
LED modules will improve safety on New York's subway, while also reducing energy and maintenance costs.
Dialight Corporation has been awarded a $1.8 million contract to provide LED trackside signals for the New York City subway system.

The contract calls for retrofitting 13,400 incandescent units with LED modules, thereby completing conversion of all of the system's more than 50,000 signals.

The LED signals are saving the city nearly $1 million a year in utility bills and maintenance. They are designed to retrofit two 16-watt incandescent bulbs with a robust module based on the latest high-flux LED and driver technology. With a projected service life of 10 years, the LED modules provide energy savings of 85 percent.

"The new signals are being well received by the city's transit workers, who have indicated they are performing extremely well, and that the saturated colors of the LEDs are much more visible, resulting in greater safety on the tracks," commented Laura Hoffmann, Dialight business development manager.

Dialight had been working with the New York City Transit Authority for the past six years in developing an LED signal that can be easily installed into a wide variety of existing enclosures without necessitating the difficult and costly removal of the lenses, some of which have been in place for more than 50 years. The result is the company's versatile 891 Series LED modules for the retrofit of rail wayside signals.
