Ridgefield, CT Outdoor Lighting: Dark Sky Rules (2026)

Section 7.8's stated purpose is to 'maximize the effectiveness of site lighting,' raise energy-conservation awareness, and 'discourage the installation of lighting fixtures that emit objectionable illumination' under § 7.8.A. The standards apply to all exterior lighting where site plan review or a special permit is required, exempting single-family dwellings under § 7.8.B. For commercial, multi-family, institutional or other non-residential uses, § 7.8.C.2.b requires vehicular and pedestrian area fixtures to be full cut-off type, IESNA cut-off fixtures approved by the Commission, or fully shielded/recessed fixtures with the lens flush to the bottom surface.

Security and aesthetic lighting must likewise be top-downward and full cut-off or shielded under § 7.8.C.3. Luminaire height is capped at 14 feet in the Central Business District and in other districts absent a Special Permit, with an outer ceiling of 24 feet even with a Special Permit under § 7.8.C.8. Non-essential lighting such as display, parking and sign lighting must run on 'photocell on - time clock off' operation under § 7.8.C.6, and § 7.8.C.10 flatly bans high pressure sodium light sources. Traditional seasonal lighting, temporary event lighting authorized by the Town, and emergency-service lighting are exempt under § 7.8.D, and the Commission may allow a Special Permit exception if it finds the proposal consistent with the regulations' intent.
