Worthy Garden Club partners with the INTERNATIONAL DARK-SKY ASSOCIATION: OREGON CHAPTER to raise awareness about light pollution. IDA: Oregon acts as a statewide base for IDA, joining a network of more than 50 chapters on five continents to preserve and protect the nighttime environment and our heritage of dark skies through environmentally responsible outdoor lighting.
Light pollution has been linked to the disruption of natural wildlife cycles and an increase in diabetes, obesity, depression, sleep disorders, and certain cancers in humans. It is a waste of energy, resources, and money and limits our ability to view the wonders of the night sky. Imagine a future in which a dark sky full of stars is only a story from the past, not an experience of the present. Our Hopservatory manager, Grant, is working closely with IDA: Oregon to collect data on several LIGHT METERS placed around Oregon, including one here at Worthy. We want to deliver the best viewing possible at the Hopservatory while preserving our dark skies for future generations.
We're committed to reducing our lighting footprint and we invite you to join.
What you Can do
Use fully shielded lighting fixtures
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. A dark sky does not necessarily mean dark ground. Smart lighting that directs light where it is needed creates a balance between safety and starlight.
Use energy-efficient lightbulbs and fixtures
Using energy-efficient options will save you money and help to reduce the carbon footprint of your home or business.
Choose no more than 2700 Kelvin bulbs, amber in color
Limit the amount of shorter wavelength (blue-violet) light to the least amount needed.
Use timers, dimmers, and motion sensors when possible
Use controls to ensure that light is available when it is needed, dimmed when possible, and turned off when not needed.
Use light only when needed, lights should be no brighter than necessary
All light should have a clear purpose. Consider how the use of light will impact the area, including wildlife and their habitats.
Talk to your friends, family, and coworkers about dark sky principles
Be informative, stay positive, and promote the 5 PRINCIPLES presented above. Suggest alternatives to their current lighting.
Contact your local city and county officials
Encourage them to implement smarter lighting practices in your community. Keep the discussion focused on the positive outcomes for the city and try to anticipate any questions that the officials might ask about costs and safety issues.
