Understanding Light Measurement & Terminology

Key Definitions

• Cutoff: The point at which light rays are completely eliminated at a specific angle
• Shielding: Construction covering top/sides of light source to direct light below horizontal plane
• Spillage: Artificial light emission onto adjoining property above maximum illumination
• Footcandle: The unit used to measure light intensity

How Light is Measured

Light intensity in Forest Lake is measured using the footcandle method. Measurements are taken after dark with the light meter held 6 inches above the ground facing the light source. The difference between readings with the light on and off determines the actual light level.

Residential & Agricultural Lighting Standards

Shielding Requirements

In residential and agricultural districts, lighting used for off-street parking or other areas must be carefully controlled. All light sources must be hooded to prevent excess light from spilling onto neighboring properties.

Bare light bulbs visible from adjacent properties or public rights-of-way are not permitted.

Intensity Limitations

Forest Lake strictly regulates light intensity to prevent nuisance to neighbors:

• Maximum 1 footcandle at street centerline
• Maximum 0.4 footcandles at property lines

These measurements ensure adequate lighting for safety without creating unwanted glare or light trespass.
