Are there colour differences between the old incandescent and new LED traffic lights?
Colour differences are very slight. It is more likely that motorists will notice how much brighter the LED traffic signals are. 7. What is the lifespan of the new LED signals compared to the old signals? The new LED traffic signals have a life span of over 10 years. The old incandescent bulbs only last about two years. In any given year, all the incandescent bulbs were replaced in either the north or south portion of The City. This signal bulb group change required a three-person crew for a period of three months to replace about 15,000 bulbs. 8. What are the benefits of the new LED traffic signals? Electricity Savings: The most significant benefit of this program will be the substantial reduction in energy consumption. Once all signals have been retrofitted, a realistic power reduction of about 80% or 8.2 million kWh will be realized. That translates into over $670,000 in annual electricity savings. The LED Retrofit Project will eliminate the cost of the annual incandescent bulb group
