DAYTON, Ohio (WDTN) — The NATO logo contest has concluded and a winner has been announced. The Dayton Area Chamber of Commerce was joined by congressman Mike Turner to announce the winner of the ...

Its bulb was declared the winner last year, after a year and a half of testing. The contest stipulated that the winning bulb be sold for $22 in its first year on the market.

If the winning bulb replaced all 60-watt incandescent bulbs in the U.S., it could save about $3.9 billion in the country's annual electric bill and avoid creating 22 million tons of carbon emissions.
