Planning commission debates LED language, color temperature and flexibility for lighting code
Summary
City staff proposed adding LED options to Section 731.2 of the land development ordinance. Commissioners recommended 'LED preferred' language, clarified that similar application types (not entire sites) should share similar color temperatures, and asked staff to return with refined wording and temperature/CRI guidance.
City staff asked the Jan. 26 planning commission to include LED fixtures in the city’s lighting code (Section 731.2) and provided draft sample language. The change would permit LED fixtures under the land‑development permit stream and align municipal standards with current commercial practice.
Commission discussion focused on three points: (1) applicability — staff confirmed the change would apply to commercial and industrial properties; (2) the current draft sentence stating that 'the same type of lighting must be utilized for all fixtures and light sources on the site' was flagged as misleading because applications such as bollards, façade lighting and parking fields legitimately use different fixtures; commissioners recommended rewording to require 'similar lighting for similar applications' rather than uniform lighting across an entire site; and (3) color temperature and CRI trade‑offs — one commissioner who self‑identified as a lighting specialist explained that color‑temperature (Kelvin) and Color Rendering Index (CRI) affect perceived glare and quality, and that typology‑based guidance (for example, warmer tones for restaurants, cooler tones for office/industrial) is preferable to a single mandatory Kelvin value.
Several commissioners favored 'LED preferred' (rather than mandatory) language to encourage energy efficiency while preserving design flexibility and permitting exceptions when appropriate. City staff said they would draft revised code language that clarifies typology‑based temperature guidance and the 'preferred' (not required) status of LED fixtures and return to the commission on Feb. 9.
No formal vote was taken on the lighting amendment at the workshop stage.
