LIGHTING-Innovation-Design

Europe shines brightly at night, as seen in this mosaic created from over 7000 pictures taken by astronauts on the International Space Station. This is the first nighttime mosaic of Europe in colour ever produced with calibrated space images.

🎥🌔 En cette fin d'année, je suis heureuse de vous annoncer la sortie du film documentaire « J’ai égaré les ombres », auquel j’ai participé en tant qu'anthropologue de la nuit aux côtés de Corentin Kimenau ✨

🦇 Ce documentaire est une production de l'Association Les Amis de l'IFFCAM (Institut Francophone de Formation au Cinéma Animalier de Ménigoute).
Ecrit et réalisé par Apolline OUDOT, Sydney Gellé et Victor Roghe.

💬"Sur une petite planète qui se prend pour une étoile, des lueurs et des rumeurs sillonnent un paysage morcelé . Dans ce dédale de milieux anthropiques, où les barrières sont multiples, les autres vivants cherchent leur chemin. Des montagnes à la mer, scientifiques et habitant-es du territoire français nous montrent qu’il est encore temps de rallumer les étoiles pour que vivent les ombres..."

🦉Avec la voix off de Gaëlle Savary

💡Et l'incroyable affiche de Florian MALLET

Immense bonheur d’avoir vécu l’avant-première au Festival de Ménigoute, le 31 octobre. Le film circule déjà dans quelques salles françaises ; pour qu’il vienne jusqu’à vous, n’hésitez pas à leur écrire : jaiegarelesombres.film@gmail.com 🌙

A powerful new New York Times feature explores the growing movement to protect the extraordinary night skies over Michigan’s Upper Peninsula.

The article highlights the grassroots Right to Night campaign, which aims to overturn a Michigan law prohibiting the establishment of dark sky preserves on state land in the U.P., and the broader question of how communities can balance economic growth with the protection of ecosystems that depend on darkness.

DarkSky’s CEO and Executive Director, Ruskin Hartley, shares in the piece that natural darkness is as essential as clean air and water — and with responsible design and installation, dark sky conservation and quality lighting can coexist.

Day 28 - Black - #30DayMapChallenge

In a world that is getting brighter every night, the black of the natural sky is becoming an endangered resource.

With their online Light Pollution Platform, DarkSkyLab offers interactive global and regional light-pollution maps, night-time satellite imagery, and artificial lighting data

Artificial light pollution is increasing worldwide with pervasive effects on ecosystem structure and function, yet its influence on ecosystem metabolism remains largely unknown. Here we combine artificial light at night (ALAN) intensity metrics with eddy covariance observations across 86 sites in North America and Europe to show that ALAN indirectly decreases annual net ecosystem exchange by enhancing ecosystem respiration (Re). At half-hourly and daily scales, we detect consistent nonlinear interactions between ALAN and night duration, with Re increasing under higher ALAN and partially decoupling from gross primary production. At the annual scale, gross primary production shows no direct ALAN response and is instead influenced by the growing season length and urban proximity, whereas Re responds more strongly and consistently across timescales. Our findings show that ALAN disrupts the fundamental energetic constraints on ecosystem metabolism, warranting the inclusion of light pollution in global change and carbon–climate feedback assessments. The authors combine light intensity data with eddy covariance observations from 86 sites to show that artificial light at night increases ecosystem respiration and alters carbon exchange, with impacts shaped by diel cycles and seasonal dynamics.

Tired of an increasingly boring academy? Well, there is always hope (for the time...). If you want to participate in two initiatives that will shape the future of studies on nocturnal cities and nighttime tourism, I invite you to send your proposals to:

1) Call For Abstracts Proposals: "The Palgrave Handbook on Nocturnal Cities", edited by Dr. Manuel García Ruiz (ISCTE–IUL) & Dr. Jordi Nofre (NOVA FCSH) 
https://lnkd.in/dMX6DyWz
This forthcoming volume (expected publication mid-2027) explores the multiple dimensions of nocturnal urban life—its atmospheres, economies, inequalities, and transformations. Extended deadline: 15 November 2025.

2) Call For Papers: Special Issue of Tourism Geographies (Q1) "After Dark – Exploring Nighttime Tourism in Tourism Geographies (Special Issue)". Guest Editors: Dr. Manuel García Ruiz (ISCTE–IUL) & Dr. Jordi Nofre (NOVA FCSH)
https://lnkd.in/dAkvyu3n
Tourism studies have long focused on daylight experiences — yet the night is increasingly becoming a vital space of touristic, cultural, and affective practices. From light festivals and open-air concerts to gastronomic trails, pilgrimages, queer nightlife, and stargazing, this special issue foregrounds the night as a crucial analytical lens for understanding contemporary tourism geographies. We invite contributions exploring: Cultural, creative, and event-based tourism after dark; Nocturnal atmospheres, rhythms, and affective practices; Governance, sustainability, and aesthetic economies of the night; Comparative and interdisciplinary approaches to nighttime tourism. Deadline: 15 November 2025

Artificial light at night not only increases emission of CO2 as of high electricity demand but has also other - until now - unknown effects on climate change. 
"Artificial Light At Night" (ALAN) is increasing carbon released by plants and animals across continents—without any increase in the carbon they absorb.

An interactive visualization from Our World in Data.

Did switching off street lights at night increase crime—or reduce it?

Dr Phil Edwards from the London School of Hygiene & Tropical Medicine, lead of the LANTERNS Project, shares new NIHR-funded research showing that streets with part-night lighting saw vehicle thefts drop by half compared with before the change.

Using 10 years of Thames Valley police data, the study explored how part-night lighting, dimming, and white light affected burglary, robbery, vehicle crime, and violence—challenging assumptions that more light means more safety.
Join this webinar to discover how smarter, evidence-based lighting can cut energy use while keeping communities safe.

Our collegue and scientific coordinator of PLAN-B Project Yana Yakushina has participated in the last podcast of Light Pollution News, and interesting conversation about raising awarness of #lightpollution.

She quotes at Frank Turina, PhD when he says "𝘊𝘰𝘮𝘣𝘪𝘯𝘨 “𝘭𝘪𝘨𝘩𝘵” 𝘢𝘯𝘥 “𝘱𝘰𝘭𝘭𝘶𝘵𝘪𝘰𝘯” 𝘤𝘩𝘢𝘯𝘨𝘦𝘴 𝘩𝘱𝘸 𝘱𝘦𝘰𝘱𝘭𝘦 𝘵𝘩𝘪𝘯𝘬 - 𝘴𝘶𝘥𝘥𝘦𝘭𝘯𝘭𝘺, 𝘺𝘰𝘶 𝘳𝘦𝘢𝘭𝘪𝘴𝘦 𝘯𝘰𝘵 𝘢𝘭𝘭 𝘭𝘪𝘨𝘩𝘵 𝘪𝘴 𝘨𝘰𝘰𝘥". In her words, calling something “pollution” brings people’s attention to ALAN as a possible form of harm. After we get this attention, we can think how we can change or reduce light.

We invite you to listen to the podcast an leave your comments about this matter: having a clear "name" (such as "light pollution) help us to raise awarness of the issues that we want to address?

Qu’espérer de plus, une vraie fierté que je partage avec vous !
Quel plaisir de constater une nouvelle fois que la solution Wizard est parfaitement adaptée aux besoins des collectivités qú’elles soient petites, moyennes ou grandes à l’échelle d’une Métropole car Strasbourg -par exemple- a également fait le choix de télégerer ses équipements d’éclairage public (armoires et points lumineux) avec Wizard Zigbee.
Un grand merci au maire d’ESMOULINS, M. Didier CHEMINOT pour sa confiance ainsi qu’au SIED 70 et plus particulièrement à M. George MIGNOT pour cette belle initiative.
Votre satisfaction est notre récompense. Vous faites rayonner une solution locale, 100% française et qui permet par la diversité de son offre d’apporter une réponse aux enjeux et besoins combinés de respect de la biodiversité, des économies d’énergies tout en préservant les usages et la mobilité des concitoyens.
Un grand bravo à notre équipe pour son implication, sa disponibilité et son professionnalisme, encore une belle réussite.

✨ FACET, la lanterne que j’ai dessinée pour Eclatec International , est présentée pour la toute première fois sur le Salon Paysalia à Lyon.

Pensée comme un objet lumineux élégant, performant et identifiable, FACET s’inspire de l’art du cristal pour proposer une lecture raffinée de la lumière. Son design facetté sobre et élégant, ainsi que ses capacités de personnalisation (bandeau latéral, enjoliveur en sous face...) en font un luminaire à la fois distinctif, innovant et pleinement adapté aux enjeux contemporains de l’éclairage public .

Disponible en deux tailles et compatible avec tous les supports standards, la lanterne peut également s'associer à une gamme dédiée de mâts et crosses.
FACET offre aux villes un marqueur visuel fort s'intégrant à tout types de contextes urbains, patrimoniaux ou paysagers. Ce n’est pas seulement une lanterne :
c’est une signature urbaine, technique et esthétique au service de la ville de demain.

Un immense merci à toute l’équipe Eclatec France pour la confiance et pour la qualité remarquable du travail mené ensemble pour ce beau projet.

We need to stop seeing darkness as backward. Natural darkness has many values. It brings beauty, contemplation, awe - and obviously financial benefits. It's not only a matter of energy saving.

Natural darkness is vital for healthy sleep, and sleep issues have a huge negative financial impact on our societies due to reduced productivity and direct health costs. But we also need darkness to protect our environment and green spaces are important for human health, especially in cities.

The interest in dark sky tourism is growing, so is the number of dark sky places worldwide. People want natural darkness, with well planned light in places and at times where they belong, not everywhere and always.

Let's stop seeing darkness as a bad thing but recognise its value. Natural darkness is precious. Let's keep that treasure.

🇲🇦✨ Premiers pas d’une coopération africaine autour de la lumière urbaine durable.

Au nom de L'Observatoire de la nuit, je suis heureux d’avoir coordonné scientifiquement le premier Africa Urban Lighting Workshop, organisé à Rabat par LUCI Association , le Ministère de la Transition Energétique et du Développement Durable - Royaume du Maroc, la DGCT, l’Agence Marocaine pour l’Efficacité Énergétique (AMEE) et la GIZ Maroc.

Durant 2 sessions de trois jours, plus de 60 représentants de villes, experts et décideurs ont échangé sur la manière de concevoir la lumière comme un levier de qualité de vie, entre sobriété énergétique, sécurité, attractivité et culture nocturne.

Cet atelier marque une étape importante pour bâtir une vision #partagée du nocturne en Afrique, fondée sur la coopération, l’écoute et la diversité des contextes territoriaux.

Light and noise pollution are growing #environmental issues and recognised threats to biodiversity. Yet, they often receive far less attention than they deserve.

As part of the PLAN-B Project, we are conducting a survey to better understand public attitudes towards light and noise pollution, how they compare to other environmental challenges, and how acceptable different mitigation measures might be.

This online #survey forms part of a wider study exploring the social and psychological factors influencing these issues. It is led by our colleagues Michael Lomas PhD and Graeme Sherriff from The University of Salford, and takes approximately 15 minutes to complete.

𝐖𝐡𝐚𝐭 𝐝𝐨 𝐰𝐞 𝐧𝐞𝐞𝐝 𝐟𝐫𝐨𝐦 𝐲𝐨𝐮?

We kindly invite you to take part. Every response matters, and your insights will help us understand how people perceive light and noise pollution and what actions might be needed to address them.

How do these forms of pollution affect you?
What changes should be made?
What would you support?

The key wavelengths for human health are missing from most LEDs. In the race to provide the cheapest brightness (maximum lumens per watt), conventional LEDs fail to provide the vital 380 nm, 430 nm & 480 nm wavelengths that stimulate the non-visual opsins (light-sensitive proteins) in the eye essential for good health.

As explained in my Substack article https://lnkd.in/eTq4e42C our eyes were
designed to see light at:
~380 nm (Opsin 5: eye develop, myopia prevent & glucose regulation)
~430 nm (Opsin 3: eye development & glucose regulation)
~480 nm (Opsin 4: Melanopsin - circadian rhythm synchronization)
 
and our bodies were designed to absorb infrared light at:
~825 nm (direct stimulation of mitochondrial energy production)

Modern LEDs may do a good job of stimulating the Visual Opsins 1 (Color vision) & 2 (Rhodopsin night vision).

But they totally fail at providing light at the critical wavelengths essential for health.

It is time that LED manufacturers realize that light is not just about vision, it is also essential for health.

At first, it looks like a random pattern of lights: the United States glowing proudly from coast to coast.

But look closer.

There’s a line.

A straight, invisible divide cutting the country in two.

To the east: dense cities, farms, humidity, and growth.
To the west: dry lands, sparse lights, and silence.

That line isn’t political or cultural: it’s natural.

The 100th meridian, where the humid east meets the arid west.
Where agriculture once stopped, and survival changed shape.

Light pollution here becomes a climate map drawn by human hands: proof that even our chaos follows the rules of nature.


This is part of my Tuesday mini-series, exploring how our artificial light reveals the deepest patterns of life, wealth, and geography on Earth.

Light pollution is destructive. Yet, paradoxically, it tells the story of who we are. And while it offers us this anthropological lens, we must still fight it , for our health, our ecosystems, and our future.

💡 I’m available for lectures, webinars or talks on light, the human body, Human Centric Lighting, sustainability and yes, even light pollution.
If you’d like to explore these topics outside the usual clichés, feel free to contact me.

GO W.A! I’m blown away by how much effort, funding and activity is being invested in dark skies across Western Australia. It really looks like you’re leading the W.A.y.

From world-class astrotourism experiences to immersive education at Scitech, Western Australia is showing how communities, science and tourism can come together to protect one of our most precious natural assets: the night sky.

The new Light Pollution exhibit at Scitech’s Here, There and Everywhere gallery is a powerful example. Visitors can experience the impact of light pollution on turtle hatchlings and the stars above, while learning how small changes in the way we use light can make a big difference for wildlife and future generations.
It’s inspiring to see this kind of leadership.

With initiatives like this, W.A. isn’t just protecting its skies – it’s setting a benchmark for the rest of Australia (and the world).

Great work Carol Redford Tristan Simpson and Scitech
