Washington University in St. Louis has made a LED retrofit with the help of City Lighting Products. The university is projected to save its Danforth Campus upwards of 75 percent in lighting energy costs and provide a substantial savings in labor and maintenance costs compared to their old exterior lighting.

Washington University aims to replace 400 existing 175-watt metal halide and high-pressure sodium vapor fixtures with 55-watt LED retrofit kits.

Ed Barry, Director of Utility Operations for Washington University introduced that, "After City Lighting Products showed us the Sylvania retrofit kit, and after many phone conversations with Sylvania engineers and City Lighting Products staff, our team determined that their D-11 or D-6 kits would not only enable us to reduce our energy consumption but also allow us to reuse our poles, bases, refractors and globes. That was totally in line with our sustainability initiative."

City Lighting Products and Sylvania offered 10 each of their D-11 and D-6 kits for use in a trial run. Washington University opted to group them in a specific area in order to evaluate their overall effect.
