Letter to the editor: Bad decision on lights

August 2, 2017

To the editor:

Eileen Horn is the director of sustainability for the City of Lawrence. In this role, she has chosen to ignore the advice of the American Medical Association and install LED lighting with a color temperature of 3500 to 4500 degrees in Lawrence. The AMA advises that LED lighting be no higher than 3000 degrees in color temperature. I refer you to the links on the Facilities Conservation Improvement Program on the city website to validate the choices of color temperature.

She has chosen to listen to engineers and the lighting industry rather than doctors on questions of human health, as well as widely disseminated research on the environmental effects of this lighting with a high blue light content.

She is fishing for appointment to the Kansas House as a replacement for John Wilson, who has resigned. While I would rather see her moved to where her decisions are less likely to damage local residents, I frankly don’t think that this episode gives evidence that we want her voting on legislation.

We should listen to, and abide by, what physicians say is safe.

This is an issue more important than it would initially appear. Higher color temperatures mean the light is cooler/bluer. If these lights are, indeed, installed, we will be stuck with them for a long time. Installing them now, even as other communities are finding them unsatisfactory, is a short-sighted decision.

A comment to a previous letter on this issue contained the following link to important information.

As an engineer, the choice of lower color temperature LEDs seems reasonable--based on the information I've seen and what I think the city's priorities should be. I suspect those trying to influence this decision are not engineers, but company representatives interested most in their bottom line.

Engineers are supposed to make choices and recommendations based on information and what they believe to be the needs of the customer. Pitting doctors against engineers isn't constructive, we're supposed to all be on the same side.
