Responsible Outdoor Lighting at Home
Five Principles for Responsible Outdoor Lighting that you can implement at home!
Too often, outdoor electric lighting installations at night are over lit, are left on when not needed, and are harmful to the environment.
Before installing or replacing a light, determine whether light is needed. Consider how the use of light will impact the area, including wildlife and the environment.
Consider using reflective paints or self-luminous markers for signs, curbs, and steps to reduce the need for permanently installed outdoor lighting.
Useful
All Light Should Have a Clear Purpose
2. Targeted
Light Should Be Directed Only to Where It’s Needed
Use shielding and careful aiming to target the direction of the light beam so that it points downward and does not spill beyond where it is needed.
3. Low Level
Illumination should be no brighter than necessary.
Use the lowest light level required. Be mindful of surface conditions, as some surfaces may reflect more light into the night sky than was intended.
4. Controlled
Light should be used only when it is useful
Use controls such as timers or motion detectors to ensure that light is available when it is needed, dimmed when possible, and turned off when not needed.
5. Warm-Colored
Use warmer-color lights where possible
