LEDs Shed Light on Philadelphia’s Historic Structures

Share this on:

The historic facades along the Avenue of the Arts in Center City, Philadelphia are being highlighted each night by brilliant, color-changing LED (light emitting diode) lighting displays.  Not only are LEDs suitable for such grand applications, but they make ideal interior lighting as well.  They are super energy efficient, cast vibrant light, and are very durable.

Unlike incandescent light bulbs, they don’t have a filament that will burn out; they don’t generate heat and waste energy; they don’t contain mercury; and on top of all that, they are long-lasting (rated for 35,000 to 50,000 hours of useful life, whereas compact fluorescent lighting offers 10,000 to 15,000 hours, and incandescent bulbs only last for 1,000–2,000 hours).  Their longevity and efficient use of energy makes them less expensive over the long run.

Through research and development, the technology of LED lighting has advanced and the cost has been decreasing over the past few years as well.  LEDs are used in wide array of devices, from traffic lights and exit signs, to TVs and radios, and flashlights to cell phone keypads.  Plus, LEDs are even available as replacement light bulbs.

So, the next time you find yourself in the City of Brotherly Love, be sure to check out how the latest technology sheds new light on history.  The LED lighting has been permanently installed to illuminate nine buildings along the Avenue of the Arts, to create a vivid nightscape throughout the year.
