Resumo(s)

Advertising light sources (LED panels, MUPI, bus shelters) contribute to urban light pollution. In 2021, Porto, Portugal, municipal tender specifications set night-time thresholds of luminance (Lᵥ ≤ 100 cd·m⁻²) and correlated colour temperature (CCT ≤ 2200 K). We report compliance and change across three campaigns (2024–2025).
