Let's save energy and resources by reducing unnecessary outdoor lighting! Combat light pollution by simply turning off lights when not needed. Be mindful of the environment and lower electricity bills. #LightPollution #SaveEnergy buff.ly/3K1mv4h buff.ly/44l1Zou

Fully shielded lights can reduce glare by up to 90%. With enhanced visibility, drivers can better identify potential hazards, react in a timely manner, and navigate roads more safely. For more information, visit: buff.ly/48uWSCJ #roadsafety #iwishtheyknewdarksky

Our eyes undergo dark adaptation to adjust to low light conditions. It typically takes 20-30 minutes for full adaptation, but it can be reversed in seconds. Let's prioritize eye health and #darkadaptation for better vision in the dark. #iwishtheyknewdarksky

Five months ago, 1000 songbirds were killed in one night after colliding with the McCormick Place. buff.ly/3SrTMdL Together, let's create a safer habitat for these creatures by following DarkSky best practices. #iwishtheyknewdarksky

What does a DarkSky approved light look like? It follows DarkSky's Five Principles for Responsible Outdoor Lighting! buff.ly/3vLxWZN Congrats to Heather in Plainfield for selecting a DarkSky-certified light and helping us protect the night! #darkskychi

Exposure to glare from poorly shielded outdoor lighting can have negative effects on vision, especially for those with aging eyes. A recent study suggests that exposure to artificial light at night may increase the risk of macular degeneration. buff.ly/47LfOMM

Smart lighting in cities can reduce energy costs and facilitate non-verbal communication. A pub uses subtle "light cueing" when it raises its lights to signal that it's time for you to leave. Can you think of any other examples of "light cueing"? #darkskychi

Nocturnal pollinators rely on darkness for their behavior, but the impact of light at night is often overlooked in pollinator gardens. Consider turning off the lights to create a suitable environment for these creatures.buff.ly/3Strxvl #iwishtheyknewdarksky
