Smart lighting means taking LEDs to the next level; it allows you to control your lights with IoT systems and create a ecosystem of lights that can interact with other software, bringing an entire world of new possibilities for your indoor spaces.

    Since we can create different light combinations to accommodate to our circadian rhythms, we can adapt our lights to many different settings and spaces, and to any particular activity or need.

    CCT and CRI

    We use CCT (color correlated temperature) to describe the relationship between the color we see coming from a light source and its corresponding temperature. Color temperature is conventionally expressed in kelvins (K). Color temperatures over 5000 K are called "cool colors" (bluish), while lower color temperatures (2700–3000 K) are called "warm colors" (yellowish).

    CRI (color rendering index) measures the ability of a light source to accurately reproduce the colors of the object it illuminates. For example, the sun has CRI value of 100, meaning that any other light source with a similar value, say 90-95, gets extremely close to be as good as natural light.


    Artificial light has been brought into our spaces for the purpose of taking advantage of the time we have when there's no sunlight. However, ill-timed exposure to light can have negative effects on our health, such as disrupting our circadian rhythms.

    That is why we need ways to improve the quality of our smart lights by applying Human Centric Lighting, which considers visual and non-visual parameters of natural light to design better and healthier smart lighting.

    Can you imagine a software that can empower your smart lighting projects?

    We have developed a software that allows you to take into account your geo location, time of the year, and sleep-wake cycles to determine the best light settings based on experimental data, data science, and sun position, getting results that are adapted to your needs.


    Common uses of optimised smart lighting can be found in homes, offices, and hospitals: we can create optimal circadian cycles in our homes to feel awake in the morning and relaxed and ready to sleep in the evening, boost productivity and concentration in our work spaces, help patients recover faster and health workers adapt to their work shifts, and allow plants grow in the best light conditions.

    At home

    You can follow your own circadian rhythm by allowing your artificial lights to change light scenes throughout the day. Feel energised or boost your productivity during the day, and feel relaxed during the evening.

    Try our daylight calculator to see what is the best light combination according to your location and your circadian rhythms.


    Kumux is currently working on scientific projects that study the non-visual parameters of light that can be beneficial to people's health.

    Help your patients to have a faster recovery and reduce their time spent at the hospital, and allow your health workers to adapt easily to their work shifts.


    Create the best work environment for your offices/workspace and employees, by setting the right light combinations to help them get ready for a day of work, boost their concentration and productivity, and prepare them to finish the day ready to go home.
