Energy Performance Lighting developed a project to upgrade the interior and exterior lighting and light fixtures at the Aspirus Medical Education Center (AMEC) in Wausau, WI. Because a portion of lighting upgrades had previous been completed, Aspirus AMEC currently had LED lamp products in stock; these lamps were factored in to the design and the light fixtures that were already upgraded to LED were accounted for and marked as “no change.”
The interior lighting upgrades consisted of upgrades with 4′ and 2′ linear lamps, as well as recessed cans with new LED bulbs, and no new ballasts for either linear or recessed can fixtures.
The 4′ and 2′ linear fixtures were upgraded with new, comparable 4′ and 2′ GE LED luminaries and no new ballasts. There were 24 linear fixtures with emergency ballasts that controlled a single lamp in each fixture, but the emergency ballasts were not compatible with the new LED lamps. The electromagnetic ballasts and lamps were not factored into the cost of the upgrade project, however EPL offered an “al a carte” option to replace the ballast and the individual lamp in each fixture. The recessed cans contained pin-base CFL bulbs that were upgraded with pin-base GE LED bulbs.
The exterior lighting improvement project consisted of upgrading exterior soffit lights and pole light fixtures. The exterior of the facility was assessed to ensure there were no exterior building fixtures or wall packs to upgrade. The recessed soffit lighting was upgrade with LED retrofit components. The exterior pole light fixtures were upgraded with new LED fixtures of comparable size. EPL conducted photometrics post-upgrade to ensure light levels adhered to IES recommended practice.
