Full Breakdown
Outdoor-lighting and dark-sky standards are part of local zoning, which ORC 519.02 places with township trustees on unincorporated land and municipal governments inside cities and villages. Where a jurisdiction has adopted lighting standards, they commonly require full-cutoff (fully shielded) fixtures, cap pole heights, limit lumens or foot-candles at property lines, and mandate that light be directed downward. Many Hamilton County communities have no formal dark-sky ordinance at all. To know what applies to you, ask your local zoning office whether a lighting standard exists and what fixtures it requires.
Violations & Fines
Where a lighting standard exists, noncompliant fixtures are a zoning violation enforced locally with correction orders and fines.
