Now there are more and more LED lights, for example, household bulbs, decorations, toys and TV. It seems that many LED lights are indoors. Then how about outdoors? What kind of outdoor lighting is flourishing?

MidAmerica announced that it would replace 100,000 streetlights in Iowa with LED lights. The project will take a long run of 10 years and is sponsored without any charges from local citizens and governments.

LED streetlightWhy would such an action be taken? Is it because Led lights are much more beneficial than general streetlights? Then what are advantages of LEDs?

MidAmerica concluded that with these new lights, 35%-50% of energy used on lighting streets can be saved. The amount of the electricity that will be saved is predicted to be equal to 32million kilowatt-hours and the carbon dioxide emissions will be decreased by 22,000 tons.

To see a more accurate data and a fact, here is another news.

It happened in Campbell last week, whose city council were considering installing more LED streetlights after last year’s conversion of 200 bulbs. It is reported that 200 LED bulbs have already saved 9,900 dollars on energy expenditure. And since the remaining 2500 traditional bulbs will cost a budget of $700,000, which means it costs approximately 56,000 dollars for the 200 replaced bulbs.

CampbellBy comparing $56,000 and $9,900, a conclusion is drawn that after 5 years and a half, this project of streetlight replacement can be paid off. Moreover, a LED streetlight can last valid for about 25000 hours, which amounts to 7 years (open for 10 hours per night.) From the statistics above, it is obvious to see the profits.

Besides energy conservancy and financial benefits, LED streetlights can also provide a better view for drivers. The brighter the road is, the fewer car accidents there might be. The LED lights are prevalent nowadays and the projects of advanced LED are absolutely advantageous. Last year the Led streetlights all over the world are about 13.2 millions pieces, and it is predicted to be 116 million in 2013 by a research firm. Then guess who will benefit most from this giant projects? Absolutely the citizens.
