Concerns about blue light prompt Lawrence City Commission to re-evaluate streetlights

The last word on the color and safety of Lawrence’s new streetlights is yet to be had at City Hall.

At their meeting Tuesday, commissioners pre-empted a report from city staff recommending the city not pursue changes to the color temperature of the LED bulbs. Commissioners said they are getting a lot of emails from residents about the streetlights and that more discussion is needed.
