Groton Utilities is bringing state-of-the-art LED technology to local streetlights with a project that will save energy, cut costs, and improve area lighting.
Begun this fall, the street lighting project will convert 2,000+ existing streetlights on public ways throughout the Groton Utilities service area to LED lights by the end of the year. The project’s estimated $850,000 cost will be funded through Groton Utilities’ conservation fund.
LED lights use 60-70 percent less energy than older technology, which saves money and is also a greener option as lower energy use means fewer emissions associated with power plants.
In addition, LED lights last three to four times longer than older lights, which helps hold down electric rates by cutting maintenance costs. And the improved light quality provided by LEDs – closer to a daylight spectrum – improves local safety. They also offer reduced light pollution with a more focused beam that lessens excess light spreading to unneeded areas.
What makes LED technology so efficient? Light- emitting diodes (LEDs) are solid-state devices that convert electric energy directly into light of a single color. Because they employ “cold” light generation technology, in which most of the energy is delivered in the visible spectrum, LEDs don’t waste energy in the form of non-light producing heat. In comparison, most of the energy in an incandescent lamp is in the infrared (or non-visible) portion of the spectrum. As a result, both fluorescent and high intensity discharge (HID) lamps produce a great deal of heat.
You can get a preview of the new LED streetlights outside the City of Groton Municipal Building. We’ve installed them throughout the complex, so feel free to drive through and check them out.
