Dartmouth LED retrofit cuts energy use by two-thirds

When Dartmouth initiated a campus-wide project to improve efficiency and make university operations more eco-friendly, one of the main focuses was installing green lighting and upgrading existing fixtures to cut energy use. The Baker-Berry Library was one of the buildings targeted for a lighting upgrade. However, maintenance staff faced a challenge. The ceiling in the library is perforated metal in some areas and solid sheet rock in others so installing new light fixtures would require locating a fixture that would identically match the current openings cut into the ceiling. Ideally, Dartmouth needed a solution that would allow the college to leave the current fixtures in place and retrofit them to be more efficient.

During its investigation of lighting options, Dartmouth discovered there aren’t 8-inch LED can light fixtures on the market, only 6-inch. Immediately, the search turned from new fixtures to LED retrofit kits. In the end, Dartmouth chose TERRALUX’s Linear LED Retrofit Kits for the project. The improved lighting quality and output from the TERRALUX Linear LED Engine, compared to the CFL’s that were used before, enabled Dartmouth to eliminate 100 fixtures from the library. Removing fixtures and the improved efficiency of the TERRALUX LED engines has resulted in a 2/3 energy savings.
