LYS Collect
LYS Collect is a simple data collection tool that allows researchers to collect light data from multiple LYS Buttons remotely. This solution is ideal for distributed, large-scale studies. It can also be used for projects involving participants who don't have a personal smartphone, where data collection will be done locally.
LYS Light Diet app and Data Platform
Let each participant connect their LYS Button to their own LYS Light Diet® app. Get further insight into the participant's light intake, chronotype, age, gender, as well as perceived sleep and energy levels. Access all raw data from the LYS Data Platform.
The LYS Button
Continuous light and movement
Used in leading research in the field of sleep, light and chronobiology accross the world, the LYS Button allows for seamless and simple tracking of light exposure. The wearable light sensing device also tracks movement with the inbuilt accelerometer. Easily clipped to everyday clothes, the LYS Button is a truly human centric tool to measure light intake with study participants.

What researchers say
“LYS is an innovative design which shows how the daily patterns of light influence our sleep-wake cycles in a vibrant, user-friendly visual display. Their data services provide great potential in assisting research on circadian rhythms, health and sleep in the future. It is definitely a pleasure to work with such a caring and enthusiastic team.”
