Working with project partners from the Seattle Lighting Design Laboratory, the Lighting Research Center (LRC) will identify a suitable outdoor lighting installation in a parking lot and conduct evaluations of energy and power use, visual responses of people in and approaching the outdoor location, and subjective ratings of safety and personal security while viewing and occupying the location.
