Energy Performance Lighting was selected by ESG to provide lighting upgrades for this project. ESG knew EPL was a sound choice as the right partner, since the project consisted of several separate buildings, interior and exterior upgrades, and would involve the security complexities common among correctional institution projects. EPL employees passed intense background checks and underwent lengthy check-in and check-out procedures each day as they arrived and left the job site. This is familiar territory for us, since we’ve worked with many correctional institutions and other government facilities.

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.


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.

For the facility’s exterior perimeter fence, we replaced high-pressure sodium fixtures with LED fixtures on 35-foot poles. We also replaced wallpacks with LED fixtures. We were able to deliver sufficient light while reducing overall number of fixtures.
