St. Paul officials have been switching out streetlight bulbs for longer-lasting, energy-efficient light-emitting diode lights since 2010, at the rate of about 1,500 lights per year.

With new types of bulbs being added to the market, city officials have begun experimenting with different types of lighting on different blocks and are asking for public feedback on the characteristics of the bulbs.

On a handful of streets in the Lexington-Hamline, Hamline-Midway and Payne-Phalen neighborhoods, St. Paul Public Works has installed different LED bulbs — and in some cases, new lighting structures — per block. The city maintains some 37,000 lights in the public right-of-way.

Residents are invited to fill out a survey with their reactions at stpaul.gov/LED. The survey, which began Monday, continues through May 19.

“This study is specifically around our residential lighting,” said Jeanette Rebar, a community-engagement coordinator for the city. “The LED technology continues to change. Are there certain lights they find glaring? Do some of the lights we might be testing create patchiness on the streets?”

In recent years, reactions to various types of LED lighting have run the gamut. Some residents specifically request them, while others say their street feels less safe because the glare causes them to spend less time on their lawns and forces them to shut their blinds at night.

Public Works is testing different LED street lights on Blair Avenue between Lexington Parkway and Hamline Avenue; on Van Buren Avenue between Griggs Street and Hamline Avenue; on Portland, Ashland, Laurel and Hague avenues between Lexington Parkway and Griggs Street; and on Magnolia, Jessamine and Geranium avenues between Earl and Duluth streets.
