Sunday Light is a simple system that quietly reshapes your day.
Place it where your day happens. Above a kitchen table, a desk, or wherever you spend your mornings.
Let it follow the sun. Sunday shifts from bright morning light to warm evening light on its own, or set your own schedule in the app.
Start your day in it. Your first 30 minutes of light matter most.
Then forget it. Sunday runs in the background, and most people feel the difference within a week.
"Sunday combines clever engineering with beautiful light in a rather beguiling way."
Financial Times

As bright as daylight, and just as comfortable. At full output Sunday reaches 34,500 lumens. It never feels harsh because the light is scattered across the whole room rather than fired from one point, so it looks and feels like sunlight.
Brightness and color are fully adjustable, with deep dimming for the evening. Set up automated schedules via the Sunday Light App.
Standard fixtures are made for visibility, at a fraction of daylight.
Sunday is an engineered system that brings daylight-level, sunlight-quality light to a whole room: 34,500 lumens, CRI 95+, shifting from cool morning light to warm evening light on its own.
