A light designed for your body

Most indoor lighting is built for visibility. Sunday is built for your body.

Sunday Light produces the right light, at the right time of the day.

Light that works with your circadian system. Not against it.

Some notes on @thesundaylight, a sort of… artificial skylight?

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…

The Sunday light is extraordinary. We change the light according to our mood; and our mood changes with the light. Way cool thing to get done!

Nat Martin is the kind of builder I admire—his product feels like art, but it's also incredibly functional. In many ways, it reflects how I think about our work at Notion.

He's a Notion customer! And as of this weekend, I became his customer :)

I was incredibly impressed by the Sunday Light. It produces a level and quality of light that approximates sunlight, yet its design allows prolonged use that is both comfortable and convenient.

Critically, you do not have to sit next to the device to get the levels of light that will deliver physiological benefits.

It felt like being bathed in sunshine.

When Hammett turned it off, I laughed at the wintery greyness that replaced it. When he turned it back on, I appreciated it even more.

For SAD sufferers and those who hate the long winter evenings, half an hour beneath the Sunday should help banish the blues.

Wow wow wow. It's so perfect. I'm just sat here admiring. It's just sublime. Cheering me up on a dreary day. It's totally energizing.

It is a gloomy Oxford winter but under our Sunday Light, it is astonishingly bright and cheery! This terrific piece of engineering solves an important problem - robustly and elegantly.

I can't believe the difference the light has made. It's like a beam of sunshine above our kitchen table. Every morning, I notice the immediate effect it has on me and my family's mood.

@natmart_in I've seen it! The cast is truly incredible. It really does feel like sunlight

This chandelier for circadian rhythms casts 10,000 lux at eye level, equivalent to ambient daylight, and outstripping the measly 500 lux found in most well-lit offices.

The science is clear that we need more light. The current options don't deliver. Sunday Light does.

Dimmable LED light fixture in stainless steel and acrylic with titanium nano-particles

The Sunday Light's large reflective panel scatters light the same way that the atmosphere does. When the light is on, the light source mimics the sun, reflected as a bright white spot, and the surface of the panel glows with a luminous, sky blue light.

At the heart of the luminaire is an LED that produces over 34,000 lumens, cooled by water flowing throughout the structure.

At its brightest the Sunday Light creates the effect of standing under a clear blue sky on a sunny day. However deep dimming means that Sunday isn't just a sunlight machine - it can be as soft and soothing in the evening as it is powerful in the daytime, featuring a color changing light output, from bright daylight (6000 K, CRI 95+) to a warm evening light (2650 K), enabling perfect synchronicity with the sun.

01. Liquid-cooled

Unique cooling technology enables sustained daylight-level output.

02. Sunlight-quality colour

Exceptional colour accuracy. Spaces feel open, natural, and true to life.

03. 34,500 lumens

10,000 lux at 60cm. Daylight-level intensity across your space.

04. Built-in intelligence

Automated scheduling, presets, and control via the Sunday app.

How it works

"Sunday combines clever engineering with beautiful light in a rather beguiling way."
