Library Saves 235,300 kWh Per Year with LEDs

Gumberg Library at Duquesne University in Pittsburgh recently completed a lighting upgrade on its first floor, using Eaton’s Neo-Ray Index light-emitting diode (LED) luminaires.

The lighting upgrade to the first floor study area and stacks included replacing a fluorescent system consisting of over 500 fixtures producing 37,160 watts. The new 110 Neo-Ray Index products consume only 5,170 watts, significantly reducing the upgraded floor’s energy consumption—more than 235,300 kWh per year.

The lighting upgrade is the latest of the university’s ongoing sustainability initiatives, which include an on-site cogeneration plant and ice storage units for most of the campus’ heating and cooling needs.

The Index luminaire incorporates Eaton’s patented WaveStream LED technology to reduce total power consumption. The product’s adjustable optical panels, available in 15 degrees, zero degrees and minus 15 degrees, also allow the luminaire to be tuned precisely to the application and space.

The Index LED products are also DesignLights Consortium (DLC) listed, qualifying the university for a potential local utility rebate.
