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. 34,500 lumens

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

02. Liquid-cooled

Sunday's unique cooling technology enables sustained daylight-level output.

03. Sunlight-quality colour

Exceptional colour accuracy and automated colour shift throughout the day.

04. Built-in intelligence

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

Your questions answered

Will this work in my space?

Sunday is designed to work in most residential and commercial spaces with a minimum ceiling height of 240cm. It’s commonly installed above kitchen islands, dining tables, home offices, and living areas - anywhere you naturally spend time during the day.

If you’re unsure, please book a 10 minute consultation with us and we'd be happy to review photos or plans of your space before purchase to confirm suitability.

How easy is it to install?

Installation is comparable to a high-end chandelier. Sunday mounts to the ceiling and connects to a standard electrical supply.

Any qualified electrician can install it, typically in 1–2 hours. We provide a clear pre-install checklist and guidance to make the process straightforward.

If you would like assistance with installation, please reach out to our team after purchase and we can provide this service for an additional charge.

How bright is Sunday Light?

Sunday light at top brightness can emit up to 34,500 lumen output. Despite its brightness, Sunday's unique design makes it feel comfortable. Light is distributed indirectly across the space, rather than emitted from a single point source, which makes this level of light comfortable, with a look and feel like sunlight on a sunny day.

Brightness and colour temperature are fully adjustable, allowing you to tailor the light to your comfort throughout the day.

Why is Sunday different to a standard ceiling light?

Sunday isn’t a decorative fixture or a conventional lamp. It’s an engineered system designed to deliver daylight-relevant light across an entire space, something standard lighting isn’t built to do.

Achieving this requires specialised optics, materials, and thermal management, along with custom components and low-volume manufacturing.
