The City and Philadelphia Energy Authority put out a call for qualifications from contractors interested in helping LED-ify the city. Philadelphia energy officials are seeking contractors that can customize street lighting so it could vary from neighborhood to neighborhood and through different times of the day. The city has not yet identified funding mechanisms for the citywide LED switchover. There’s no implementation date either. The request for qualifications, due in March, will be followed by a request for proposals. So there’s still some time to walk down a Philadelphia street at night under that old sepia light.
