Exterior energy savings
Interior energy savings
“Electrical costs are lower. Staff appreciate that the light adjusts in the evening and gives you a feeling of day ending and time for bed. Lighting is 110% improved from what we had before.”

Energy Performance Lighting was selected by Trane to provide lighting upgrades for this project, completing interior upgrades in the first phase of the project and completing exterior perimeter lighting upgrades in a subsequent project phase.
Project requirements dictated that the interior would be partly a fluorescent-to-fluorescent upgrade. The facility had a wide range of fixtures, including various T8 fixtures with 2, 3, or 4 lamps, as well as a range of incandescent and CFL lamps. EPL adhered to security requirements unique to correctional institutions. For instance, we selected specialized fixtures with special nuts and bolts to prevent inmate tampering. EPL employees became accustomed to lengthy check-in and check-out procedures and intense background checks.
We streamlined interior lighting by upgrading the facility to low-watt T8 lamps. We also helped the client streamline inventory, maintenance and replacement costs by achieving the right light levels while reducing the number of lamps per fixture and changing incandescents and CFLs to consistent LED lamps.
EPL also tackled a mid-project challenge that can cause stress and delays if you’re not working with the right lighting upgrade partner. The client originally selected Program Start Ballasts in the fixtures, but changed direction to Instant Start late in the project after supplies had been ordered. Thanks to EPL’s solid relationships with suppliers and our commitment to keeping the project running smoothly, we were able to return supplies and get new ballasts and swap those that had already been installed, and still meet the project deadline.
For the facility’s exterior perimeter fence, we replaced high-pressure sodium fixtures with LED fixtures on 35-foot poles. We were able to deliver sufficient light while reducing overall number of fixtures.
