• Ditch non-essential external lights
Moonlight and the starry sky are more beautiful than any ’designer’ lighting or anything you can buy in a DIY store
• Keep lights off except when needed
Don’t leave lights on all night. Instead, use properly adjusted sensors so that lights are activated when needed and promptly turned off afterwards
• Use light fittings that direct and confine light to the task in hand
Purposeful lighting goes only where it’s needed and doesn’t spill into the neighbourhood or the sky
• Ensure that lights are only as bright as they need to be
Scale essential lighting to the situation - needlessly bright lights are most likely to intrude and pollute by glare, reflection and scattering
• Favour warm-toned light
The blue-rich light included in the emissions of brilliant white LEDs is particularly far-reaching and harmful
• Explain to others the many ways in which natural darkness is beneficial and light pollution harmful.
• Visit dark places, preferably with others, to experience for yourself the beauty of natural night, its power to heal, inform and inspire.
