GE LED Traffic & Rail Signals
GE LED traffic and rail signals replace incandescent units to better meet the critical 24/7 reliability needs of municipalities, rail yards and transit operators. Benefits of advanced LED technology in these 365-day-a-year devices include recurring energy savings and lower maintenance.
Environmental Benefit
If a municipality replaces the incandescent lamps at 100 intersections with GE LED traffic signal modules, it could consume 93 percent less energy and avoid approximately 1,100 metric tons of CO2 emissions on the U.S. grid per year. This is equivalent to the CO2 absorbed annually by over 300 acres of Southeastern U.S. forest or the CO2 emissions of over 210 cars on U.S. roads.
Operating Benefit
A city of one million inhabitants can save over 9.3 million kWh of electricity and over $1.0 million in electricity costs by replacing 21,500 incandescent lamps with GE's LED traffic signal modules, assuming a commercial electricity price of $0.11 per kWh.
GE Light-emitting diode (LED) lighting systems
Light-emitting diodes (LEDs) are compound semiconductor devices that convert electricity to light. In fact, GE scientists invented the first practical application of LEDs in the 1960s. LEDs are vastly different from traditional incandescent, fluorescent and neon light sources.
Unlike lamps that can shatter, LEDs are robust and highly resistant to shock and vibration. Due to the solid-state nature of these devices, there are no filaments to break, no moving parts to fail and no glass components of any kind. With LEDs, breakage during transportation, installation or operation — a common problem with traditional light sources — is virtually eliminated, speeding up installation times and installer training.
The benefits of using LEDs vary depending on the application, but typical technology features include:
- Up to 90 percent energy-cost savings
- A long life of up to 50,000 hours
- Minimized maintenance hassles and costs
- Low-voltage operation
- Excellent cold-weather performance
Many of GE’s LEDs are Restriction of Hazardous Substances (RoHS) and National Science Foundation (NSF) compliant and recognized by the Underwriters Laboratories (UL). GE’s unique design provides an environmental benefit because it has no UV, no infrared, no glass and no mercury, making handling and disposal less of a concern.
LEDs have applications in retail displays, signage and architecture, and transportation.
LED signals
Ever-demanding traffic and rail signal applications require constant reliability 24 hours a day, 365 days a year. By applying GE LED signals in place of older fluorescent or incandescent technologies, municipalities, rail yards and transit operators can benefit from energy savings and lower maintenance costs.
