Today, large numbers of traffic controlling authorities located in different regions and cities of United States use LEDs for traffic light signals. Reason for this is that traffic warning light powered by using LEDs result in reduction of costs without compromising on the quality. In this article, experts have highlighted about few of the potential savings associated with LED lights.
Very Less Lifetime Operating Cost
Although Light Emitting Diodes have initial higher purchasing price, they facilitate for saving big amounts of money in terms of lifetime operational expenses. According to a research study conducted on traffic warning lights based on LED, LED traffic signal balls cost about 70 dollars as compared to incandescent lights available at only 20 dollar.
However, when users have included maintenance cost and energy usage, they found lifetime operational costs of LED bulbs, lamps and other similar light sources as approximately equal to one-third of the costs of traditional incandescent lights.
Involves Cost of Only Few Dollars
In any typical incandescent bulb utilizes 100 watts of bulb and operates for 24 hours in one day, it will utilize 2.4 kilowatt hours on daily basis. Hence, if individuals assume cost of about 8 cents in 1 KWH, signal would cost about 20 cents in one day or about 73 dollars in one year for operation.
On the other side, equivalent LED signal would consume only 10 watts and lead to costing only 7 dollars in one year. In fact, a small city with only few traffic-warning signals would result in drastic energy savings.
Allows Huge Savings at Different Intersections
With the help of LED traffic warning sign one can expect to save more than 600 dollars at a particular intersection (by assuming eight signals), while a big city or a suburb may save about millions of dollars or even more based on numbers of intersections. Along with this, changing of bulbs also result in saving on its labor cost.
Save Money on Red Lights
Red lights stay in ON mode for about 5,300 hours in one year and utilize relatively higher amount of energy in any traffic signal as compared to other (green and yellow) lights. In addition, they have large size and possess higher wattage. If you consider the average, you will find red lights, as using about 85 percent of total energy consumption takes place in any traffic signal.
In this situation, if traffic authorities opt to replace red-colored incandescent directional arrow of 150 watts with only 10-watt of LED lights, they would achieve highest possible savings without compromising on the quality of the lighting system.
