Whether it’s a game-winning goal in the final minute or a dramatic equalizer in a battle for first place in the standings, Interbay Stadium is synonymous with top-caliber college soccer. It is one of the finest facilities not only within the Great Northwest Athletic Conference but in all of NCAA Division II.
DMD was retained by the City of Seattle Parks to upgrade the existing lighting system to LED. We completed the design for and tender documents for the replacement of the existing metal halide sports lights with new energy efficient LED lighting with improved colour rendition and innovative glare shielding to reduce lighting impacts on local residents adjacent to the field.
Following the installation, DMD undertook light level testing and measurements to verify results. Results were improved such as the uniformity of the lighting, color rendition and reduction of lighting brightness at the adjacent residential condominium complex from 250,000 candela to under 4,000 candela.
The existing soccer field lighting used 114 luminaires and we were able to reduce that to 38 luminaires resulting in a power reduction from 200 KW to 55kW.
