Thanks to new lighting technologies, Seattle may be heading toward a brighter, more efficient future but will it be better?
As each warm, languid summer night falls on Seattle, most of the city's 84,000-plus streetlights flicker to life, bathing our nocturnal urban landscape in their familiar pinkish-orange light. These lamps lit by high-pressure sodium bulbs have come to define our city's night time appearance, coloring our streets, our neighborhoods, our parks and our collective consciousness with an amber-hued gloominess that seems as natural to us as cloud cover.
But at the intersection of 16th Avenue E and E Highland Drive, something seems amiss. This neighborhood of stately homes, just a block east of Volunteer Park, is one of the city's oldest, dating back to the 1800s. Massive maple trees tower over the streets; lawns, homes and gardens are precisely maintained; and there's an aura of anachronism here that seems lifted from a movie set”except for the blinding streetlights, that is.
