Street lights

Lincoln is switching street lights to LEDs. These images show a street with the existing High Pressure Sodium Vapor lights (left) and a new LED replacement.

I am a retired electrician and found Dr. Matt Steffens' Local View ("New LED lights could have health costs," June 30) interesting.

I have a piece of material that prisms light. If I take it outside, I can see all of the colors of the rainbow. So, I took it and an LED flashlight into a closet this morning. The piece of prism material reflected mostly blue from the LED flashlight. Other primary colors were visible but not like the blue.

Dr. Steffens and the American Medical Association may be on to something.

John Huseman, Lincoln
