More energy-efficient streetlights have changed the nighttime ambience of neighborhoods across the state. Some now wonder: Is the future a little too bright?
Local governments and utility companies have converted thousands of streetlights to energy-saving LED fixtures, which typically cast a brighter, whiter light than the warmer glow of their high-pressure sodium predecessors. Those who notice the change either welcome it as an extra dose of security or squint at a harsh intruder in the dark.
"It's not very welcoming to these neighborhoods," said Scott Barkman, standing beneath an uncovered LED light recently affixed to a wooden pole outside his Minneapolis home. "It kind of makes them this police state."
He is one of many south Minneapolis residents scrutinizing lights Xcel Energy has begun installing throughout the city. Some Duluth residents are so passionate about the issue that they commissioned a highly produced documentary, citylightsstarrynights.com, about the harm caused by glaring streetlights.
Whether a light is irksome often depends on the color, brightness, style of fixture and its proximity to a home. Others worry about light pollution chasing away the starry night and addling birds and other creatures.
"We've had a day-night cycle for billions of years," said Scott Vesterstein, a co-owner of Fitger's in downtown Duluth and executive producer of the film. "And just in the last few years with this new LED technology we've been radically changing it."
Duluth ultimately installed warmer-hued lights during a reconstruction of Superior Street, but Vesterstein said about 1,900 people have also signed a petition opposing the harsh white lights elsewhere in the city.
The LEDs are now starting to illuminate some of the most heavily populated neighborhoods of the Twin Cities as Xcel reaches the final leg of its project to convert 90,000 lights in 350 communities across the state. Minneapolis and St. Paul crews, which are also converting city-owned lights, have so far focused on downtown areas and major thoroughfares.
