Our mission is to enable healthier living with light and to make it available for everyone
The vision
In Danish LYS means light. Short, simple and straight to the point.
Our name carries not just our Scandinavian heritage but also a promise that we never take light for granted — it’s too important.
LYS looks beyond the lifespan of a lightbulb, aesthetics of a lamp, and the technology of smart lighting. Instead, we focus on what should always come first: people and supporting their healthy livelihood.
We’re here to enable personal light adjusted to people’s inner rhythms and daily routines.
The science
Based on the latest research in sleep science, our technology focuses on the most important factor for your sleep-wake cycles. Your exposure to light.
Light is vital to peoples’ health and wellbeing — and yet in the modern world light is an overlooked and untapped resource.
From the founders
LYS began with a simple question from our founders, Christina Friis Blach Petersen and Hugo Starrsjo: if light shapes how we sleep, feel and perform, why is healthier light still so hard to access in everyday life?
Christina brought the human-centred design perspective. Hugo brought the biomedical engineering and healthcare lens. Together they built LYS to turn circadian science into practical tools people can actually use.
What started as a Kickstarter in 2016 has grown into an award-winning company with users in 53 countries. The ambition has stayed the same from day one: make healthy light easier to understand, easier to measure and easier to act on.
