Scientific research

In the beginning of this century, scientists found that the sleep/wake rhythm is controlled by non-visual aspects of light. Thus, light is not only important to see, but also crucial for well-being and health. In close cooperation with scientific researchers, health professionals and light specialists, MediluX developed optimal light solutions, especially for mission critical rooms, elderly homes and hospitals.











24/7 light solutions for more safety, better health, higher alertness, improved well-being and higher performance in mission critical and nursing environments.
