Port of Seattle, Terminals 90 and 91
Retrofit Team
Lighting Installer: Port of Seattle Marine Maintenance, Seattle
Materials
The terminals, which provide mooring for cruise ships, commercial workboats and fishing vessels, were in need of a lighting upgrade. “We are proud of our port, but the existing high-pressure sodium lighting had reached its useful life span and wasn’t delivering the coverage we needed to meet current standards,” explains Robert Hoyman, Marine Maintenance project manager, Port of Seattle. “We were also convinced we could save energy costs with new lighting technology.”
Light Emitting Plasma (LEP) luminaires were selected for installation on existing poles, which are 65-feet high. LEP luminaires provide increased color recognition, are dimmable to 20 percent and carry a lifetime rating of 50,000 hours. Energy costs are expected to decrease by more than 50 percent. In addition, the installation is dark-sky compliant, and the crisp white light will enhance security cameras’ image acuity and the ability to recognize faces.

The Retrofit
Work on the Port of Seattle’s docks is often 24/7, and longshoremen have told the port the new plasma lights have significantly improved their working conditions.
Hoyman concludes: “We are very pleased with our new lighting on the piers. The luminaires installed easily onto our existing infrastructure, and we were able to aim the light where it’s needed to eliminate dark areas.”
