The Township of East Caln, Pa., recently converted all of its street lights to LED lamps, which will save more than $12,700 in energy costs over the next five years.
Previously, the streets were illuminated by inefficient mercury vapor (MV) and high pressure sodium (HPS) street light fixtures.
Stouch Lighting, an Ashton, Pa., lighting distributor specializing in LED lighting and energy efficient lighting products, assisted the township in the transition.
"They used their lighting expertise to make the most efficient lighting recommendations to cover our needs and were particularly helpful in specifying the proper lighting in the residential areas where light trespass was a concern,” said Bonnie Lucy, director of finance at East Caln Township.
Residents have really noticed the changes.
“The streets are so much brighter now, and that brightness is consistent throughout the township, offering the public more security than ever before," Lucy said. "That yellow-green glow that the mercury vapor fixtures emitted and the orange look that the high pressure sodium lights seemed to cast over the streets are gone.”
The street lighting LED retrofit also qualifies East Caln Township for receiving cost reduction incentives from their local utility company and, in addition is projected to reduce East Caln Township’s greenhouse gas emissions by more than 32,000 pounds per year (equivalent to 94 trees saved per year).
