It feels good to spend the day in daylight. But that doesn't happen when I'm working inside. Especially in the winter. So, for years, I've used super-bright LEDs while I work. They quite noticeably improve my energy…






Sunday Light is an artificial skylight: a ceiling light, hung like a chandelier. At 34,500 lumens it fills a whole room with daylight-level brightness, and it follows the sun's colour through the day.

“The Sunday Light is indeed the closest thing to sunlight you can buy. 10/10, no regrets.”

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."
Colour shifts from 6000K morning to 2650K dusk, automatically to support your body clock.
Bright light from the moment you wake, for mood, energy and focus.
34,500 lumens of comfortable daylight, water-cooled to run all day.
Colour Rendering Index (CRI) 97+, so your home looks lit by daylight.
The app works on iOS and Android. Every light comes with a remote.

Specifications
Sunday works in most residential and commercial spaces with a ceiling of at least 240 cm (94.5 in). It goes above the places you spend your day: kitchen islands, dining tables, home offices, and living areas.
If you are not sure on placement, please send us a couple of photos or arrange a consultation and we can assist.
Installing Sunday is like installing a chandelier. It is simple to install and typically takes 1-2 hours. It hangs from the ceiling and connects to a standard electrical supply, running on 110-250 V AC (50-60 Hz) so it works with US, UK and European electrics.
We provide a step-by-step installation guide and can also arrange installation for you after purchase with our preferred installers.
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 colour are fully adjustable, with deep dimming for the evening. Set up automated schedules in the Sunday Light app.
Standard fixtures are made for visibility, at a fraction of daylight.
Sunday is an engineered system - an artificial skylight - that brings daylight-level, sunlight-quality light to a whole room: 34,500 lumens, CRI 97+, shifting from cool morning light to warm evening light on its own.
Find out more about how we built Sunday here.
Sunday Light is a ceiling light fixture (a light fitting, in UK terms) that installs like a chandelier and behaves like a skylight: one fitting delivers 34,500 lumens of full-spectrum, daylight-level light to the whole room.
It is not a desk lamp or a recessed skylight - no roof or ceiling work needed.
