Waipahu commercial, industrial, and recreational development must use full cut-off shielded fixtures under ROH 21-4.100, protecting dense plantation-era residential blocks from light spill.
LUO 21-4.100 is Honolulu County's principal outdoor lighting and dark-sky standard, enforced throughout Waipahu. It requires full cut-off shielded fixtures for commercial, industrial, and outdoor recreational development to eliminate direct illumination onto adjacent country, residential, apartment, apartment mixed-use, or resort districts. Non-enclosed rooftop gathering spaces must shield lighting so it does not pass beyond the rooftop. The rule protects Waipahu's densely packed plantation-era residential neighborhoods from commercial glare along Farrington Highway, Waipahu Depot Road, and the Westridge shopping corridor. It complements state HRS 201-8.5 Night Sky Protection Strategy and LUO Article 4 General Development Standards.
Noncompliant fixtures trigger DPP notices of violation, daily zoning fines, and required retrofit to full cut-off shielded lamps within specified cure periods.
