Glenwillow and Solon are right next to each other on the map, so how do their light controls compare?
The simplest answer is, unfortunately, that Glenwillow's streetlights leak as much excess light as Solon's do.
A quick tour of Glenwillow reveals that neighborhoods opt for period style lighting while major roads use tall, unshielded streetlights.
The shared characteristic between them? Both types of streetlights let light out in multiple directions, so not all light is directed downwards.
This period style streetlight is on, even in broad daylight. Beyond the interest of shutting down light pollution, increased attention to the number of streetlights and the times of day they're on or off could save a lot of energy.
Take a look at the photo above. Both sides of the road are lined with unshielded streetlights and placed at an excessive frequency. Note that the fact that the streetlights are "unshielded" means that light floods in all directions; a significant portion of light is actually going parallel to the ground and polluting the sky!
The night sky, though cloudy, is still infused with light and can hardly be called dark. What modifications do you think should be added to streetlights to change this?
