Summary
Corona Municipal Code Section 17.84.070 requires all exterior lighting to be designed to direct light downward, with minimal spillover onto adjacent residences, sensitive land uses and open space. The same section bars glare from arc welding or torch cutting from being visible past the property line.
Glare. Glare from arc welding, acetylene torch cutting or similar processes shall be performed so as not to be seen from any point beyond the boundary line of the property. All areas of exterior lighting shall be designed to direct light downward with minimal spillover onto adjacent residences, sensitive land uses and open space.

Full Breakdown
84, addresses lighting and glare together in two sentences. The first bars glare from arc welding, acetylene torch cutting or similar industrial processes from being visible from any point beyond the property line where the work occurs. The second sets the city's general exterior lighting design standard: all areas of exterior lighting must be designed to direct light downward, with minimal spillover onto adjacent residences, sensitive land uses and open space. The section does not set a specific lumen cap, mounting-height limit or full-cutoff fixture mandate the way a dedicated dark-sky ordinance might; instead it operates as a performance standard checked against a project's site and lighting plans during development review, with the Planning and Development Department confirming fixtures are shielded and aimed downward before approving a plan.
090(B), which separately requires City Engineer approval and post-installation inspection for lighting serving parking lots. 040(B)(8) defines the residential and institutional 'sensitive land uses' the lighting standard is written to protect.
Violations & Fines
Because Section 17.84.070 sits inside Chapter 17.84, a lighting design that fails to direct light downward or spills onto a neighboring residence is enforceable as a misdemeanor under the chapter's general enforcement clause, Section 17.84.040(I)(3), with each day of noncompliance a separate offense under Section 1.08.020(A).
