Campaign seeks to reduce light pollution

— Robert Wagner says he's tired of not being able to see the stars at night.

In response to the thousands of yard lights, streetlights and other signs that blot out the sky, Wagner has started a campaign to dim the lights at night, starting with state parks in Missouri and Kansas.

"I started noticing all the light shining in our bedroom window at night, and I thought, 'Good grief. Why haven't we addressed this?'" said Wagner, 39, of Kansas City.

Besides masking the stars in the night sky, excess light is wasteful, said Wagner, citing a study by American and Japanese astronomers in 1999 that found excess light costs $7.15 annually in the Kansas City area.

Wagner said the light pollution could be reduced simply by turning off unneeded lights and installing fixtures that direct light to where it's needed, not into the sky or across a neighborhood.

Old streetlights, for example, often have bulbs that send light in all directions. Some newer light fixtures, such as those used on highways in the renovated Grandview Triangle, have extra skirts near bulbs or black paint on reflectors to reduce glare. The light shines downward only on the area illuminated.

A Missouri House committee is considering a bill that would make such devices more common.

The bill would authorize the Missouri Clean Air Commission to develop standards and regulate light emissions near parks to preserve natural skies.

If the bill is passed, by 2025 no protected place would be allowed to have night sky luminance any brighter than twice the natural luminance. And the bill would require that by 2055, 90 percent of the protected areas have no more than 10 percent additional light above natural luminance.

The delayed target dates would give businesses time to install efficient lighting as old fixtures wear out, said Wagner, who plans to seek similar legislation for Kansas parks.

Night sky advocates are seeking similar measures across the country.

"What would normally be millions of stars blazing away in a black sky has been lost to the majority of the American people," said Robert Gent, the president of the International Dark Sky Association. "We're turning the night into day."

I remember AL Bundy tried something like this.

The state needs to start conserving electricity, and reducing the lights in the parks is a great place to start. Plus that's our tax dollars that are burning long into the night.

I wonder if that is why only 1/2 of the street lights lining Kasold from 15th to 22nd are not on.

Gee only $ 7.15...that is cheap
