A bit different, this one. I grew up as an ardent 8-bit and 16-bit gaming kid in the 80s and early 90s, and still have a soft spot for retro games. The long Eid break gave me time to try something Iโd been turning over for a while: Vibe-code a small game, but with a twist. I wanted to base it on something closely tied to what we follow in lighting design: the ROLAN manifesto.
Iโd been hearing a lot about enhanced capabilities of Claude Opus 4.8, so sat down to direct, and let it build. And spawned "๐๐ฎ๐ฝ๐๐ฎ๐ถ๐ป ๐๐๐บ๐ฒ๐ป", a small browser platformer about bringing back the night sky. You win with the responsible use of light.
Each of the five worlds is built on one of the five #ROLAN principles: Useful, Targeted, Low Level, Controlled, and Warm-Coloured. Dim a fixture to proper level, aim it downwards or at the faรงade instead of the sky, stomp the glare imps, collect stray photons, switch glare to curfew, and warm the coastal lamps so the turtle hatchlings find the sea.
What Iโm quietly hoping is that it lands with the kids who get fascinated by light. ROLAN and dark skies can feel abstract at that age. A game doesnโt lecture; it lets them feel why restraint is the point, long before they ever read a lighting spec or even know what lighting design is.
In fairness, these are early trials. The gameplay is fairly easy, and right now it leans into a retro 80s vibe I love, backed with a retro soundtrack for each world. But plan is to grow it into a more modern game with richer graphics, deeper gameplay, and genuinely thoughtful lighting design baked into the visuals. When? That remains to be seen. But itโs a plan.
A gentle & playful nod to the folks at DarkSky International, the authors of the ROLAN principles, and friends across this beautiful lighting community. Do give it a shot!

Dans les villes de demain, l'รฉclairage ne sera plus seulement un service. Il deviendra une infrastructure stratรฉgique. C'est le message que nous partageons dans notre entretien avec Light ZOOM Lumiรจre et que nous avons le plaisir de mettre en dรฉmonstration dans le cadre d'Urban7 ร #Nancy. Pilotage intelligent, adaptation aux usages, maรฎtrise รฉnergรฉtique, รฉvolutivitรฉ des รฉquipements : autant de leviers qui permettent aujourd'hui aux collectivitรฉs de construire des espaces publics plus performants et plus durables. Parce qu'un territoire intelligent commence souvent par une lumiรจre plus intelligente. #Urban7 #SmartLighting #SmartCity #Nexiode #AgoraMakers #EclairagePublic
Faire revenir la nuit : un enjeu dโรฉclairage, de santรฉ et de dรฉcision urbaine Dans son article ยซ Faire revenir la nuit ยป, publiรฉ dans #QueChoisir nยฐ657 | mai 2026, le sujet de la pollution lumineuse est abordรฉ comme un vรฉritable enjeu de sociรฉtรฉ.
Lโรฉclairage artificiel nocturne, devenu omniprรฉsent, ne concerne pas seulement la visibilitรฉ ou le confort. Il touche aussi la santรฉ, les rythmes biologiques, la biodiversitรฉ, la consommation รฉnergรฉtique et la qualitรฉ de vie dans nos villes. Pour les collectivitรฉs, les urbanistes, les concepteurs lumiรจre et les acteurs de lโamรฉnagement, la question nโest donc plus simplement : faut-il รฉclairer ?
La vraie question devient : comment รฉclairer mieux ?
- oรน รฉclairer ? - quand รฉclairer ? - comment รฉclairer ? et surtout, comment ces choix sont-ils perรงus par les usagers ?
Cโest prรฉcisรฉment dans ce type dโarbitrage que les outils dโaide ร la dรฉcision visuelle peuvent apporter de la valeur. Avec Light and Innovation SAS, ร travers la plateforme #VisualSense, lโobjectif est dโaccompagner les acteurs de lโamรฉnagement, de lโurbanisme et de la conception lumiรจre dans la comparaison de scรฉnarios visuels, lโanalyse des perceptions et la prise de dรฉcision.
- comparer diffรฉrents scรฉnarios lumineux, - objectiver les perceptions, - recueillir les retours des usagers et aider ร choisir des solutions plus sobres, plus acceptables et mieux adaptรฉes aux usages rรฉels.
Rรฉduire la pollution lumineuse ne signifie pas faire disparaรฎtre la lumiรจre. Cela signifie concevoir une lumiรจre plus juste, plus utile, plus sobre et mieux adaptรฉe aux usages rรฉels.
Un sujet qui peut intรฉresser les acteurs engagรฉs sur ces questions : INGELUX, christophe MARTY Cluster Lumiรจre Cerema, INSERM TENS Groupe ADP #ANPCEN.

Still feeling grateful after yesterdayโs [en]LIGHTenment Journey Webinar โจ What made this event special for me was seeing people from different countries and backgrounds come together to talk about light, design, creativity, and experience. These kinds of conversations remind me why building international educational communities around lighting is so meaningful.
I also want to sincerely thank our amazing speakers, Sharon Stammers, Martin Lupton, Roger NARBONI, Mahdis Aliasgari, and Ezzat Baroudi, for their generosity, insights, and inspiring talks.
And a special thank you to Women in Lighting for supporting this event.
To keep these conversations going, Iโve created a Light en Light Academy WhatsApp community where weโll be sharing opportunities, resources, events, open calls, and the webinar recordings once they are uploaded. You can join through the link in the first comment ๐
On 16 May, we marked the International Day of Light. ๐ก
Light surrounds us every day, yet we rarely stop to reflect on how deeply it shapes our lives. It does far more than simply help us see. Light can boost our mood, support our wellbeing, and help us feel and perform at our best. Whether at home, at work, in school, or outdoors, the light around us influences how we think, feel, and experience the world.
Smart, human-focused lighting can make a real difference. By combining natural daylight with electric lighting that adapts in colour and intensity throughout the day, we can create spaces that better support the way we live, learn, and work, therefore creating a lighting experience that flows with us, every hour of the day and in every environment.
Today we celebrate the UNESCO International Day of Light ๐ก
Light is so deeply integrated into our lives that we rarely stop to think about it. Beyond illumination, it quietly shapes almost every aspect of modern civilization: the way we communicate through optical fibers, diagnose diseases with medical imaging, grow food, explore the universe, manufacture technology, navigate cities, measure time, and even understand the origins of life itself.
For thousands of years, light has extended human activity beyond daylight, enabled knowledge to spread through writing and observation, inspired art and culture, and driven scientific revolutions that transformed society. Today, photons carry the information behind the internet, power precision manufacturing, and enable many of the technologies defining the future.
What is fascinating is that most of this remains invisible in our daily routines. We notice the screen, not the photonics behind it. We notice connectivity, not the light pulses traveling through glass. We notice the diagnosis, not the optics enabling it.
Light is not just something we see. It is one of the fundamental infrastructures of human progress.
Cities need smarter streetlights because darkness has become a budget decision. ENVIOTECH is betting that the winning infrastructure business wonโt ask municipalities to rip everything out, but to make the lamps they already own cheaper, safer and easier to control.
The research supports that boring-sounding bet. A 2024 field study on context-adaptive street lighting found that municipalities are under pressure to manage lighting more efficiently as electricity costs rise, and that full adaptive installations using sensors, traffic data and remote control outperform conventional lighting strategies on energy consumption [1]. ย Another 2024 paper shows why retrofit matters: older lamps can be connected to LoRaWAN-based monitoring systems without replacing the whole streetlight, helping cities detect defects, configure devices remotely and bridge the gap between old public lighting and modern smart infrastructure [2].
That is exactly where ENVIOTECHโs model clicks. Instead of selling a giant infrastructure overhaul, it sells retrofit kits for existing streetlights, so cities can dim lamps when no pedestrian or cyclist is nearby, monitor them centrally and avoid full replacement costs.
In 2025, StartHub Hessen reported an Eschborn pilot and the companyโs claim that its kits could save about 70% of energy use, even with LED lamps [3].
In 2026, ENVIOTECH raised more than โฌ1 million in pre-seed funding to expand pilots, rollouts and its product portfolio, with newer coverage describing up to 80% energy savings [4].
The takeaway is simple: their success comes from making public safety cheaper, not optional.

Gรฉopolitique des รฉtudes de stratรฉgies lumiรจre et de trames noiresโฆ De retour de 3 ateliers pรฉdagogiques et professionnels sur des รฉtudes de stratรฉgies dโรฉclairages et de trames noires, en Thaรฏlande, en Uruguay et en Ukraine, jโai pu mesurer la diffรฉrence de connaissances et de pratiques quโil existe encore aujourdโhui sur ces sujets ร lโรฉchelle de la planรจte.
Il y a 40 ans, jโai commencรฉ ร imaginer mes premiรจres stratรฉgies dโรฉclairage pour des villes franรงaises et depuis 15 ans, jโai aussi รฉtudiรฉ mes premiรจres trames noires en France. Et je peux donc constater aujourd'hui le chemin parcouru par rapport ร dโautres pays qui en sont souvent ร lโรฉlaboration de leurs toutes premiรจres รฉtudes de ce type, avec un besoin impรฉrieux et nรฉcessaire de mรฉthodologie, mais aussi avec une soif rรฉconfortante dโapprentissage et dโacculturation ร lโurbanisme nocturne.
La France compte ร ce jour plusieurs centaines dโรฉtudes liรฉes aux stratรฉgies dโรฉclairage et certaines villes en sont ร leur 3e gรฉnรฉration dโรฉtudes de ce type. Ces stratรฉgies d'รฉclairage concernent des agglomรฉrations, des villes de toutes tailles, des quartiers ou des sites protรฉgรฉs. On peut donc rรฉellement dire que la culture de lโurbanisme lumiรจre qui sโest peu ร peu transformรฉ en un urbanisme nocturne respectueux de la biodiversitรฉ et du ciel nocturne, voir en un urbanisme de la nuit, rรฉparateur et facteur de lien social, fait dorรฉnavant partie intรฉgrante de la majoritรฉ des stratรฉgies urbaines franรงaises.
Dans beaucoup dโautres pays dans le monde, ce nโest pas toujours le cas. LโEurope (Grande Bretagne incluse) est certainement le continent le plus en avance sur ces sujets stratรฉgiques liรฉs ร lโรฉclairage urbain. Du Nord au Sud de lโEurope, de la Suรจde ร lโEspagne, de nombreuses รฉtudes de stratรฉgies dโรฉclairage et les premiรจres รฉtudes de trames noires ont รฉtรฉ rรฉalisรฉes.
LโAsie (avec la Chine comme leader) et le Moyen Orient sont en train de rattraper leur retard dans ce domaine trรจs particulier des รฉtudes stratรฉgiques dโรฉclairage avec un grand absent, lโInde, qui balbutie encore dans ce type dโรฉtudes.
Les Amรฉriques et surtout quelques pays dโAmรฉrique Centrale (Mexique) et du Sud (Brรฉsil, Chili, Colombie, Uruguay) ont, depuis une quinzaine dโannรฉes, progressรฉ dans ces รฉtudes stratรฉgiques et devraient servir de modรจle ร beaucoup de pays voisins dรฉsireux de mieux maitriser la nuit de leurs villes.
LโOcรฉanie, avec lโAustralie en locomotive, a encore pas mal de chemin ร parcourir pour gรฉnรฉraliser ce type dโรฉtudes.
Enfin lโAfrique du Nord, grรขce ร des รฉvรฉnements internationaux exceptionnels ciblรฉs comme le prochain Moroccan Lighting Days for Africa ร Tanger au Maroc, les 12 et 13 juin 2026, va aussi pouvoir dรฉvelopper des approches innovantes et essaimer progressivement dans le reste du continent avec des รฉtudes stratรฉgiques dโรฉclairage exemplaires.
Toutes les รฉquipes ont pensรฉ, crรฉรฉ, produit, installรฉ et connectรฉ un tout nouveau format dโexposition de nos solutions. Bravo et merci ร tous !!

The cityโs initiative to replace outdated high-pressure sodium streetlights with more energy-efficient, longer-lasting LED lights seems like a bright idea. Too bright for some.
Residents on New York Avenue, including Hunter Debutts, are seeing the glare.
โThis oneโs pretty bright, and definitely at night, it feels like daylight almost inside,โ he said, pointing to a new LED light outside his home, which for some reason was on at 1:30 Tuesday afternoon.
Debutts says his next door neighbor is having similar problems.
โHer enclosed porch there โ she used to sleep out there and said she canโt sleep out there because it is so bright,โ Debutts said.
Today marks the 2026 International Day of Light, and it feels like an important moment to reflect on a question that sits quietly beneath so many of todayโs economic and societal challenges: not how long we live, but how well we live, and for how long we can continue to contribute.
We are entering a period where two powerful trends are colliding. On one hand, populations are ageing and working lives are extending. On the other, healthy life expectancy is moving in the wrong direction. The real risk isnโt longevity itself, itโs the growing gap between lifespan and healthspan.
This is where the conversation needs to shift.
Productivity is often framed through the lens of technology, AI, or economic policy. But beneath all of this sits something far more fundamental: human biology. Our ability to think clearly, stay resilient, learn, collaborate and perform is not abstract, it is physiological. And physiology is shaped every single day by the environments we design and create.
Light is one of the most powerful and maybe the most overlooked of these environmental inputs.
It regulates our circadian rhythms, our sleep, our energy, our hormones, and even cellular function. Yet modern life has fundamentally altered our relationship with it. We spend most of our time indoors, under lighting conditions that bear little resemblance to the natural signals our biology evolved to depend on.
The consequences are subtle at first, but cumulative: disrupted sleep, reduced cognitive performance, metabolic strain, and over time, a quiet drift away from optimal health.
If we accept that people will need to work longer, then we also have to accept responsibility for the conditions that determine whether theyย can.
Because the future of productivity will not be decided solely by innovation or policy, but by whether we are designing environments that support long-term human capability, or erode it.
On this International Day of Light, itโs worth recognising that light is not just a design feature or a question of aesthetics. It is infrastructure for health. And increasingly, it is infrastructure for economic resilience.
If we want longer, healthier, more productive lives, we have to start with the environments we create and the signals we give to the human body every day.
The full article explores this in more depth, linking healthspan, ageing, productivity and the role of light in shaping the life curves of individuals and populations.
The Power of Light, Seen Through Different Perspectives ย How does lighting influence the way we live, move and feel? ย As part of the International Day of Light Day of Light, Iโm sharing an image that reflects the positive impact of light in our everyday lives. ย Lighting is a passion of mine, it impacts on virtual every thing we do and all environment's we may find ourselves in and this includes the absence of artificial light to enable us to enjoy the pleasure of natural light, the night sky. As promoted by Lighting Europe and ourselves within WSP light has a value. Well designed lighting enables us to go out at night in safety, promotes the local economy and facilitates leisure and sporting activities without adversely impacting on the environment. ย Now Iโm passing the light to Fiona Venn, Lilian Fu, IALD, CLD, LC, MIES and Adrianna Barr to share an image and their own perspective on how light makes a difference. ย WSP Places WSP Transport & Infrastructure WSP in the UK & Ireland
