2 rules for unincorporated Pinal County, Arizona.
Verified from official government sources
Pinal County adopts a dark-sky outdoor lighting ordinance (Development Services Code Chapter 2.195) and follows Arizona's light-pollution law, which requires outdoor light fixtures to be fully or partially shielded. Shielded, warm-color, lower-lumen lighting protects the region's dark night skies and observatories.
A.R.S. 49-1102
All outdoor light fixtures shall be fully or partially shielded except incandescent fixtures of one hundred fifty watts or less and other sources of seventy watts or less.
Pinal County's dark-sky lighting ordinance and Arizona's light-pollution law limit light spilling onto neighboring property or into the sky. Fully shielded fixtures project light below the horizontal plane, curbing glare and light trespass across property lines.
A.R.S. 49-1101
Fully shielded means fixtures are shielded in such a manner that light rays emitted by the fixture are projected below a horizontal plane.
