LYS Technologies - Live Healthier with Light

Hi, we're LYS. We’re not here to build smarter lighting products, but to enable a smarter and healthier living with light. We look beyond the lifespan of a light bulb, the aesthetics of a lamp and the technology of smart lighting systems. Instead, we focus on what should always come first — people and supporting their healthy livelihood. Just as air, food, and water, light is a natural and vital source to health. To most people, the absorption of light is an unconscious choice in life. It’s everywhere, always. But not necessarily in a healthy way. We can choose to eat better, drink less, run more… but what about the things we don’t see, but subconsciously feel? The things that can truly energise our day and make us happier and healthier. We are here to improve people’s health by enabling personal light adjusted to their inner rhythms and daily routines. Light can only be truly healthy, if it’s powered by people and the lives they live every day. So, whenever you are ready to feel the difference, we are here to help you live a healthier life with light.
