Going Green: Lemoyne College Introduces LED Lights
LeMoyne College is putting a big spotlight on a lighting revolution, LEDs or light emitting diodes and it started with a lighting change in just a couple of offices.
“What we found was people coming into our offices saying 'The light in here is wonderful, can we get it in our office' so last November we went to the larger project with 200 tubes. We lit two classrooms, one hallway and all the building down here (physical plant). It's worked out very well,” said Jim Dishaw, LeMoyne College Director of Facilities Management.
The difference between florescent lighting and LED is very noticeable.
As a matter of fact we've found we've had to reduce the fixture to three tubes instead of four to keep the light from becoming excessive.
Unlike a florescent that radiates light 360-degrees, these are directing light at about 90-degrees. They're pointing straight down.
The LED produces all this light using about half the electricity of a traditional florescent and it lasts about five times longer.
We can figure that the LED tube will last from 60,000 to 100,000 hours so if you're lighting an office 12 hours a day, five days a week that tube will last 25 and a half years at an average of 80,000 hours. They last a long time.
The problem is the cost difference, a traditional florescent light tube costs less that three-dollars
At $75 a tube, which is what we paid, we'd have to keep them in service for ten years to get a pay back on it. That's a long time to get a pay back.
But there is another pay back.
LeMoyne College is very committed to a green and sustainable environmentally friendly existence.
Plus Jim Dishaw fully expects higher demand LED lighting and technological advances to keep bringing the prices down and eventually they'll replace all 25,000 florescent lights on campus.
