The overall purpose of this pathway lighting project is very simple and direct. We will be replacing the incandescent light bulbs that are currently being used in the “lollipop” (is there a more technical term for the name of these fixtures? Spherical lamps?) fixtures to energy efficient LED light bulbs to conserve energy and money while reducing greenhouse gas emissions. By only replacing the light bulb inside the fixture, we are able to reuse the whole fixture and pole that will help preserve the overall appearance of the campus. These spherical lamps are used as a “way-finder” spotlight that help guide students from one location to the next and we wanted to make sure that this purpose will continue to be carried out after the light bulb change. This was a key component in our project objectives because we wanted to retain the overall image of the campus by keeping the same fixture, which also helped us save money by only switching out the light bulb. Another key component of this project is the reduction of greenhouse gas emissions by reducing purchased electricity consumption. A typical incandescent light bulb uses about 3285kWh per year, which cost $328.59 per year while a LEDs uses 329kWh per year that cost $32.85 per year. This will be a major reduction in cost, energy consumption and greenhouse gas emissions for the campus. On a yearly basis, the usual incandescent light bulb will release 4500 pounds of carbon while LEDs will only emit 451 pounds of carbon. The difference in carbon emission is significantly valuable to creating a more sustainable environment on our campus.
