Sodium is back: Cree and Lumileds unveil 1900K lamp
Cree and Lumileds have teamed up to develop an LED lamp with the characteristics of high pressure sodium lamps. It will have the same correlated colour temperature of 1900K, a similar colour rendering index of 50 and a near-absence of blue. The companies say the light source – dubbed 19K5 – was specifically developed to significantly reduce blue light emissions of outdoor lighting applications while still maintaining illumination and energy performance. The 19K5 option emits a warm, amber-white light with less than 2 per cent blue content between 400nm and 500nm. At 171 lm/W, the efficacy is better than traditional high pressure sodium, which ranged from 75 to 140 lm/W. Powered by Lumileds’ Luxeon 3030 LEDs with NightScape Technology™, 19K5 is, says the brands, aimed at municipalities and ‘blue-light-sensitive regions’ where reducing light pollution, and its impact on people, wildlife, and the night sky, is a priority. ‘19K5 provides a thoughtful, intentional choice for communities proactively seeking to reduce blue light emissions,’ @Kurt Wilcox of Cree Lighting told the Circular Lighting Report. The LED module uses NightScape technology, which minimises the blue component of LED modules and which won a prestigious Build Back Better Platinum Award in 2023. Blue light content is a critical factor as it has been shown to have a significant impact on the circadian rhythms and behaviours of humans, plants, and wildlife. It is increasingly the focus of attention for local authorities, municipalities, policy makers and legislators. Some local authorities – such as Maui in Hawaii – even limit blue to under 2 per cent of new exterior light. Phosphor-converted amber, or a 3000K white LED and an amber filter or amber optics are options, but both have significant downsides. NightScape Technology has already been available in Luxeon 3030 HE Plus and Luxeon 5050 Square LED emitters, two workhorses of the outdoor lighting industry. • Learn more about sustainable lighting at Circular Lighting Live 2025, Recolight’s flagship conference and exhibition, on Thursday 25 September at the Minster Building in London.

This simple, sweet cartoon illustrates and vocalizes the reasons for good public lighting. Watch it for some pointers to persuade neighborhoods and decision-makers of the “interplay between technical aspects of lighting and social dynamics within urban communities that is so often lacking.”

Let’s light wisely and responsibly — for science, society, and the stars. #InternationalDayOfLight #DarkSkyShanghai #SustainableLighting #LightInnovationSociety
"After almost 100 years on the planet, I now understand the most important place on Earth is not on land, but at sea." This is Sir David Attenborough's message in his new documentary, "Ocean". 🌊
Last night, my team and I sent another issue of DarkSky's Nightscape to the printer. In this June issue, we take a close look at marine light pollution – that is, how nighttime light from coastal settlements, cities, ports and shipping lanes profoundly affects life in the #ocean, altering reproductive cycles, feeding patterns and growth timing of aquatic life. 🐠 🦈 🪼 🦐 🦞 🦑 🦭 🐬
"Ocean" delivers the sombre message that people have taken the seas for granted, pushing all life on Earth to the brink. But, Attenborough also stresses that our oceans are #regenerative if we give them a chance by reducing our impact. Eliminating artificial light at night in our oceans would be an achievable goal that has profoundly positive effects. 🐢 🐸
In this issue, which will be hitting mailboxes in June, we interview Prof Tim Smyth of Plymouth Marine Laboratory (PML) about their research into artificial light on marine environments and find out what can be done to protect and restore our miraculous oceans.
Nightscape is a perk for DarkSky International members and supporters. You can join for US$35/year and get four issues of Nightscape, as well as supporting dark sky advocates around the world who are working to protect the natural night, which is disappearing rapidly. 🌌 https://lnkd.in/eGc7SkHf

What does it feel like regarding light pollution at any given spot in the world?
This new map application allows an estimate experience on a virtual 360° sky dome, showing what light pollution levels are to be expected from which direction.
One can also compare sites, to find the best (and darkest) place to be for star gazing and astronomical observations, or to just enjoy the natural night.
Downtown Crossing saw the highest number of violent crimes in years in 2024. Paired with increased drug use and homelessness, public safety concerns persist.

Scientists in Thailand have assessed which technology between PV, wind, or piezoelectric energy is better for powering street lighting and have found solar is the winning tech, as it proved both economically and technologically feasible.
Wrapping up official Dark Sky Week with something special: Nightness — an interactive geospatial visualization on how artificial light affects plant ecosystems. 🌱✨
Built on Google Earth Engine, Nightness uses multi-spectral satellite imagery to track the spread and intensity of nocturnal illumination — and its impact on vegetation patterns. This is achieved by combining multiple layers from both low light radiance (VIIRS) and infrared (NDVI) satellite sources into a single cartographic presentation.
My interest in remote sensing began during my architectural and urban design training, where I became fascinated by how we can observe and understand environments from a distance. Nightness grew out of that long-standing curiosity, now combined with a focus on ecological impact. It's open-access under a Creative Commons license: free to use, share, and build on.
Artificial light at night without professional lighting design disrupts natural cycles that plants and entire ecosystems have evolved with over millions of years. It alters flowering times, growth, and species interactions. As our cities grow brighter, thoughtful lighting design that balances human and ecological needs becomes ever more critical.
While Nightness is a personal citizen science project and not a professional research study, I hope it brings visibility to an issue that often goes unseen.
