LEDs mean cheaper, more efficient lighting for towns

How many workers, and how long does it take to replace 5,000 street lights? Well, let's put it this way: Last month, White Plains and the New York Power Authority started a $3.6 million project to replace all of old high-pressure sodium lights in the city with new LED bulbs. On any given day, weather-permitting, up to four two-member crews are out on city streets, replacing lights. They expect to finish by July.
