Restoring Darkness

LEDs came along in the early 2000’s. They emitted light. They were energy efficient. What could be bad? Ask Mark Baker who’s highly sensitive to certain LED lights. And there are people worse off than him who cannot neurologically tolerate the type of radiation emitted by LEDs. Imagine if you couldn’t go to a store or walk under street lights lest you get dizzy, acquire a migraine or fall into an...

Our host, Michael, has learned a lot from reading children's books to his kids. Anna’s book, “Can You See The Stars Tonight?” we’re sure, is no exception. We are always hopeful for the next generation, so let’s teach our children about the impact of light pollution with Anna’s book. And you can’t go wrong with cute little puffins! Anna is a children's book author and illustrator who is passionate...

Dr. Darley gives us a new term (that we’re totally stealing!). Instead of describing light pollution to people as too much light, she feels people respond more positively to the problem if you describe it as a “darkness deficiency.” Dr. Darley goes on to explain the hazards of too much light - sorry, of a darkness deficiency - in your environment when you’re trying to sleep, like hormone imbalance...

If bright light at night bothers you, it is much worse for marine life, and they don’t realize it, they just react. Their instinctual biological processes change in reaction to artificial light and sky glow which then affects the food chain. To add to that, the blue light from LED’s penetrates deeper into the water. The sky glow disrupts biological processes that are guided by moonlight. Dr. Davie...

Juliana Olsson is an exhibit writer and editor at the Smithsonian’s National Museum of Natural History. In order to write all the labels visitors will (hopefully) read, she’s constantly learning about new topics, exploring the collections, and going on field trips to fossil digs and dark sky sites. She holds an M.A. in Museum Studies from Johns Hopkins University, and a B.A. in Film Studies and In...

It’s been over 5 years since Dr. Kyba was on the Get A Grip On Lighting podcast. Between then and now, we created Restoring Darkness which is a much more appropriate place for Dr. Kyba to be as his research is on skyglow and artificial light at night. He points out that when lighting up a building to make it an experience, it is no longer an experience when you do it EVERY NIGHT! We bet you’ve nev...

Dan is a landscape lighting designer and he is on our side. He tries to stay away from “on at dusk off at dawn” sensors. As Dan says, for good design. you need the darkness. You can’t just pump light into an area and call it good lighting. Good lighting is controlled and does not contribute to light pollution. Dan Jobbins is a lighting designer, based out of New York’s beautiful hudson valley. He...

Watch for Restoring Darkness Episode 76, out tomorrow. And don't forget to give to The Lighting And Darkness Foundation to fight light pollution. https://restoringdarkness.com/donate  

Just like we’ve been saying all along, Todd doesn’t want to take away everyone's light at night. He just wants people to be mindful and reasonable about lowering light pollution. He removed the carriage light above his own garage many years ago. Sure they look nice and classy, but they blast light everywhere. And just like Christmas lights, they don’t need to be on at three in the morning while ev...

The Lighting And Darkness Foundation is taking on its first project! With your donations (please donate at https://restoringdarkness.com/save-the-night-in-wasatch-back-utah ) we can help Shawn and Lisa and the other concerned residents, preserve their Wasatch Back night sky in Utah. Find out what the story is in this podcast. Lisa and Shawn are co-founders of Save Wasatch Back Dark Skies along wit...

Michael talks with our guests about the new Smithsonian exhibit, “Lights Out: Recovering Our Night Sky. It sounds like this exhibit will convince any skeptic of the importance of restoring the night sky. Watch out for a future episode, live from the Smithsonian. Dr. Kimberly Arcand is a leading expert in astronomy visualization and has been a pioneer in 3D imaging, printing, and extended reality a...

Join us for our inaugural episode of The Darkness News Update. Scott Wachter, from the Lighting Industry News Brief ( https://naild.org/lighting-industry-news-brief ) joins Michael Colligan to bring you the latest news around darkness restoration. Watch for future episodes to coincide with Restoring Darkness podcast episodes. 

Michael welcomes a fellow Canadian to the podcast. Michael and Dawn discuss the never ending pursuit of continuous improvement, the interchangeable use of the terms sustainability and energy efficiency (they are NOT the same!), the use of cheap and energy efficient lighting creating more light pollution, and the legal precedents that are inadvertently sustaining light pollution. They even touch on...

Dr. Randle comes to us from the U.K. based Butterfly Conservation, one of the largest insect conservation organizations in the world. Dr. Randle points out that artificial light at night affects pheromone production in some female moths and sperm count in some males. Along with all the other environmental pressure, light at night has caused a 32% decline in population since the 1970’s. Thanks to t...

Mike comes to us from the North York Moors National Park in the north of England. Mike has done ALOT to fight light pollution in his area. He has: developed a Dark Skies Festival; encouraged businesses to collaborate and to become Dark Skies Friendly; oversaw the application to become an International Dark Sky Reserve from inception to successful designation. He’s even successfully influenced the...

Here at Restoring Darkness, we are on a mission to eliminate light pollution. Dr. Barber wants to tackle “sensory pollution.” He is doing that by running the Sensory Ecology Lab at Boise State University and studying the effects of light and sound pollution on birds, bats, and insects. Let’s eliminate light pollution, then we’ll start the “Restoring Silence” podcast! Dr. Barber completed his BS an...

You’d think a landscape lighting designer wouldn’t really be concerned with sky glow. “Just light up the landscape and the sky be damned!” But you would be wrong if you thought that about Kathryn. Her number one concern when designing is to not add to light pollution. She strongly advises clients to turn off their lights by 10 pm, and even earlier if you aren’t around to enjoy them. She’s a big ad...

Sometimes it’s a good idea to go to the source. So we went to the founder of the Responsible Outdoor Light At Night conference (ROLAN), Karolina Zielińska-Dąbkowska. Karolina explains to Michael and John that as a lighting designer, she had questions that she couldn’t find answers to. And researchers wouldn’t let her in because she wasn’t in their circle. So Karolina went out and got her own PhD a...

If you ever doubted the impact on wildlife of humans just being around, let Sheldon tell you how the turtle nests in Hawaii bounced back in 2020. Luckily that trend continues with her army of volunteers that help redirect hatchlings away from artificial lights that lead them away from the water. Michael and John also discuss with Sheldon how there are light pollution ordinances in almost every cit...

We all know cities are a big contributor to light pollution. Charlotte Gage from Adfree Cities in the United Kingdom, contends that one of the biggest offenders is digital advertising. LED’s are getting brighter and advertising signs are being left on all night, drowning out views of the night sky but also destroying people’s sleep who live nearby these signs. Charlotte, Michael and John discuss w...

Roland is from the Royal Astronomical Society of Canada, but he speaks proficiently, beyond the perspective of astronomy, on many of the other aspects of light pollution. Roland talks with Michael and John about LED street lighting, the safety light at night straw man argument, cars hitting lamp posts because of glare, and some surprising facts about blue light that you might not have heard before...
