What is the focus of a lighting (dark sky) ordinance?
The goal is to allow property owners and citizens a reasonable amount of nighttime light. City lighting ordinances spell out guidelines that are easy for property owners to understand and implement.
Types of Light Emissions – Kelvin and Lumens
Some lighting ordinances limit bulb color temperature (Kelvins) and bulb intensity (Lumens), as well.
Kelvins (Color Temperature)
Kelvins refer to the color temperature of the light emitted. The lower the Kelvin number, the warmer the color. The higher the Kelvin number, the bluer the color. Warm white (orange spectrum) lighting is often used in homes, libraries, and restaurants, while soft daylight (blue spectrum) lighting is used in healthcare settings such as hospitals, clinics, and dental offices.
Check the light bulb’s packaging to determine the color temperature before you buy. All packaging for LED and CFL bulbs will provide color temperature information. It’s best to use low color temperature bulbs (warm white) for exterior lighting. A color temperature of 3000K or lower is recommended.
