Irvington, NJ Outdoor Lighting: Light Trespass & Shielding (2026)

Section 650-11(O) is a flat, Township-wide performance standard: all exterior lighting must be shielded, directed or buffered so that glare or direct lighting or reflection will not be a nuisance to surrounding properties. It doesn't carve out an exception for commercial, industrial, or institutional property, and it isn't tied to a footcandle table or a specific fixture type, so the test the Zoning Officer applies is whether the light or its reflection reaches a neighboring property as a nuisance. The same section reinforces that standard from the other direction: Section 650-11(N)(4) lists any use which emits excessive and objectionable amounts of dust, fumes, noise, odor, smoke, vibration, glare or waste products among the uses specifically prohibited in every district in the Township, meaning an operation whose lighting produces objectionable glare can be cited as an unlawful use in its own right, on top of any lighting-shielding violation.

Together, the two subsections give a resident or a business two separate hooks for a light-trespass complaint: the design of the fixture itself under Subsection O, and the objectionable character of the glare it produces under Subsection N(4).
