Light spill
Urban Design Guidelines for Victoria, published by The State of Victoria Department of Environment, Land, Water and Planning in 2017 suggests that light spill is: ‘Unwanted light falling on areas outside those intended for illumination, and that causes annoyance, discomfort, distraction, or a reduction in visibility. Often defined as light illuminating areas outside the property line containing the lighting system. But may also be applied to lighting in public spaces that affects amenity in private spaces.’
