The Montana State Hospital Warm Springs exterior lighting consisted of a large variety of lights, including floods, yard lights, can lights, wall packs, and pole lights. A lighting project was completed replacing all of the exterior lighting with new energy-efficient LED lights. Over 280 lights were changed during this project. In addition to saving 413,920 in energy each year, the new LED fixtures provide a better quality of light and will require much less maintenance.
This project received $14,250 in utility lighting rebates. The utility rebate brought the net project cost to an estimated $116,705. The annual energy cost savings was estimated at $13,920. The simple payback of the lighting retrofit is 8.38 years, not including maintenance savings.
