At jetlite, we know that lighting is more
than just illumination – it’s the key regulator
of the inner clock, supporting well-being
and performance. Many people already
know jetlite for its cabin lighting solutions
designed to reduce jet lag. However, continuous
research and validation drive its innovations.
FROM SCIENCE TO APPLICATION
Think about the night shift mode on a phone. A
simple change in screen lighting can help improve
sleep by reducing blue light exposure.
Now imagine scaling that concept to an entire
aircraft, where lighting adapts to flight routes,
time zones, cabin interiors, workflows and even
individual chronotypes. That’s exactly what jetlite
does – scientifically measuring, analyzing
and optimizing lighting to support the body’s
natural rhythm, helping passengers adjust faster
and allowing crew members to stay alert and
recover better. Light is the most powerful external
factor that supports the inner clock. By adjusting
color temperature, intensity and timing,
jetlite actively helps the body adapt to new time
zones, reducing jet lag by up to three hours. But
the approach doesn’t stop there.
RESEARCH AS THE DRIVING FORCE
Innovation in aviation requires science-based
solutions. jetlite’s technology is built on onground
and in-flight studies with Lufthansa,
proving that jetlite’s lighting scenarios improve
sleep, support melatonin regulation, and enhance
well-being. But science never stands
still – jetlite continues to optimize its solutions.
In 2024, four test flights to North and South
America were conducted with customers to test
and refine cabin lighting for passenger and crew
needs.
In addition, jetlite leads the consortium of the
BMDV-funded Chronolite project. Together with
Hella, Charité, TU Ilmenau, Lufthansa Technik
and other partners, the project develops connected
lighting solutions for aircraft, trains, cars
