Lightening Things Up with LED’s

When it comes to matters of sustainability, we often talk about how all the little things that we do can collectively add up to make a big difference. Here are a couple examples of some small scale improvements that were made by switching to more efficient LED lights.

The next time you see one of our flag poles illuminated, take a look a closer look. What used to be the job of a 455 watt fixture is now being done by a 45 watt LED fixture. Not only are the new LED’s about a quarter of the size, but per year they save the University 3,132 kilowatt hours of energy and $225. What used to be a $239 operating cost is now a mere $13.70.

Similar updates were made to the University’s aircraft warning lights on top of Hylan, Rush Rhees Library, and the Computer Studies/Carlson Library building. These lights were changed from 116 watt incandescents to 3.5 watt LED’s. The annual savings to the University is 2,464 kilowatt hours and $177 with a new operating cost of $5.50 compared to the incandescent cost of $183.00. 
As improvements like these are continuing to be made, the U of R continues on its path to become a more sustainable place to be!!
