Virginia Department of Corrections Engineering Department is building its newest prison in Southwest Virginia, Grayson County, with almost 100% fully shielded outdoor security lighting. They have had the foresight as well to use darker, non reflective surfaces on roofs and grounds, (mostly grass and dirt, and dark red roofs). Future prisons in other counties when replaced can use this same type of night sky optimal lighting.
If a prison with its need for maximum security can use these lights, than so can any construction. Highest praise to the engineers who have committed to reducing light pollution by their willingness to listen to new ideas, and in so doing are setting a good example for other states' Corrections Departments.
