Sunlight on demand
The Artemis is a quantum dot circadian lighting system with spectral precision conventional LEDs cannot match. In commercial supply for eight years in hospitals, senior care and offices. Now being qualified for space and defence environments.
Source measurements: office recipe, midday setting, 6 ft, no diffuser. Ask us for photometric data for your layout.
Light is the primary signal for the human circadian system, which governs sleep, hormones and cognition. Most buildings, vehicles and habitats are lit in ways that disrupt that signal, and the cost shows up as fatigue, errors, sleep medication and healthcare spend.
For a hundred-person workforce, that is over a million dollars a year in lost productivity and healthcare costs. In a spacecraft, a submarine or a control room on rotating shifts, the same disruption hits a population that cannot step outside.
That is not a research problem. It is an engineering problem, and it has been solved.
The Artemis
Quantum dots let us place light energy exactly where the circadian system responds, around 480 nm, and move it through the day without the spectral compromises of phosphor LEDs. Hardware and scheduling software are built together.
Narrow-band quantum dot emission tuned to the melanopic response. Daytime stimulus and evening wind-down from the same fixture, tunable 2700–6500 K, with CRI above 92 at every setting.
Light schedules follow the occupant's day, the shift pattern or the mission timeline, so the biological signal arrives when it should.
Produced with established manufacturing partners, so supply at scale is a production line, not a plan.
Proof
Deployed where the cost of fatigue is measured, and studied by the people who measure it.
Space & defence
Sleep disruption in crewed missions drives reliance on sleep medication and degrades performance. The same light-driven disruption reaches mission control and ground crews working around the clock, a far larger population than any crew.
The Artemis brings proven, manufacturable circadian lighting to that problem. Environmental and flight-readiness testing is the next phase, and we are building the partnerships to complete it.
International Astronautical Congress 2024, alongside the Canadian Space Agency.
Three space agencies and two space companies have each invited technical proposals.
A naval variant of the system was prototyped in 2019 for confined crew environments.
ESA Industry Space Days 2026 and the Canadian delegation at Space Tech Expo Europe, Bremen.
An integration partner already inside the ESA and CSA supply chain, and a testing partner to take the Artemis through environmental and flight-readiness qualification.
On the ground
Earthlight is our spin-out for the built environment. It gives building projects the financial case to keep circadian lighting through value engineering.
