It is a sign of wastefulness and inefficient use of power, the group says. The problem exists with older fixtures that throw light everywhere, both into the heavens and the eyes of motorists and pedestrians, the two said. A naked, unshielded light fixture creates glare, which can be distracting to drivers and pedestrians. Glare is particularly bothersome to people who suffer from night-blindness and older people, Forbes said. On the state level, legislation to regulate light pollution was directed to a study committee which is now meeting.
Business is wary of the regulations.
Some businesses can't buy liability insurance if the use of night lights is restricted, said Eric Emmert, government affairs manager for the Greater Manchester Chamber of Commerce. Downtown businesses have been able to battle graffiti by lighting alleys at night, he said. And light engineers the Chamber consulted attribute most of the glow over Manchester to reflected light, he said. Yet, the chamber and Manchester businesses are willing to talk to the group. At city hall, the Manchester Planning Board will take up light regulations after Jan. 1, said Chairman David Boutin.
