Lighting Switch Cuts UW Costs, Reduces Carbon Emissions
December 8, 2011 — Costs will be reduced and light quality improved at University of Wyoming greenhouses after switching from conventional high-intensity discharge lamps to LED-based systems.
Conversion to the LED lights from LumiGrow will reduce carbon emissions while cutting costs.
"Our decision to go with LumiGrow was based on two factors: cost and light quality," says Casey Seals, Laramie Research and Extension Center (LREC) greenhouse complex manager.
LumiGrow representatives estimate the retrofit will save more than 13,000 kilowatt-hours of power and avoid emission of 29,000 pounds of carbon dioxide annually. It estimates $5,666 will be saved based on Rocky Mountain Power's current rate of 4.2 cents per kilowatt-hour, and not adjusted for possible rate increases, over the LED lights' 10-year lifespan.
UW greenhouses are research sites for many different departments in the College of Agriculture and Natural Resources.
"LumiGrow had the fixtures that were most compatible with the research that will be conducted," says Seals. "After speaking with some of their representatives, I believed that if we ever had a problem or questions about the lighting, they would have it resolved with no hoops to jump through. They have excellent customer service and a quality product."
