some communities, such as old and chestnut hill, need the warm light. “ We don't want to deprive the characteristics of a community, & throughout; He said.

as again, people's preferences for gender. In 2011, in Northern Liberties in some streets after installation of the LED street lamp, conducted a survey in the city, the results showed that women prefer brighter LED. “ Women like it more bright, & throughout; He said. “ They want to see more clearly who came to them, prevent to hide. ”
