Light trespass is a condition in which undesired light is cast on a property or a dwelling and becomes harmful when it negatively affects the well-being or activities of individuals at that place. In particular, light trespass can disturb sleep and meditation, prevent star gazing or simply interrupt the peace of a beautiful summer evening.
All lighting that spills outside a property, even if it does not directly bother someone, must be considered a waste of energy.
