Car dealership lighting submittals involve higher illumination targets than standard parking lots because the primary function is merchandise display, not just circulation. Plan reviewers evaluate whether the lighting layout supports both sales visibility and safe customer movement while controlling spill light at the property perimeter.
Display lots typically target maintained illumination levels of 20-50 fc horizontal at grade to support vehicle visibility after dark, while customer parking areas fall back to standard commercial parking thresholds. The combination of high-output display fixtures and lower-output circulation fixtures in a single site creates a multi-zone calculation that must document each area independently.
Frontage lighting along public roadways adds a third zone with its own trespass and glare restrictions. The photometric plan needs to demonstrate that the high illumination on the display lot does not create prohibited spill or glare conditions at the property line or roadway.
