Sunday is more than a light.
With a 34,500 lumen output, a quality of light
that closely matches the sun and the sky,
and simple installation, there is
nothing else like Sunday.
This is why we call it

a sunlight machine.

A portal to the sky

Sunday’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.

Bask in sunshine

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

- Rhodri Marsden, Financial Times

Turning on Sunday is like turning on the sun.

Sunday creates a new category of lighting indoors. It brings 40 times more brilliance and cutting edge colour quality to any room.

Vivid luminosity

The human eye is a remarkably dynamic instrument - a normally-sighted person can see perfectly in a low-lit living room (about 100 lux) and in full sunlight (about 100,000 lux). Indoor spaces are commonly lit only with up to 500 or 1,000 lux, and outside on a cloudy day, you might see about 5,000 lux.

Sunday brilliantly illuminates a huge area with 5,000 lux and higher, reaching 10,000 lux within 60 cm of the sheet. Other lights designed to mimic sunlight can achieve significant lux values only at very limited ranges (for example, one popular SAD lamp advertises 10,000 lux within 10 cm of the light itself).

In total, Sunday produces up to 34,500 lumens.

Vibrant colours

Sunday delivers this huge output without feeling overwhelming. Modern high-fidelity LEDs, like the one that powers Sunday, have CRI values* of 95 and above, meaning that the colours of every object under Sunday will appear as vibrant as it would outside.

* The Colour Rendering Index (CRI) is a common measurement for the quality of an artificial light source. The higher the CRI value (up to 100) the closer the light is to matching sunlight in its ability to represent colours correctly.

The longest bar represents a 30,000-lumen output, significantly higher than other bulbs, which range from approximately 2,000 to 10,000 lumens. The graph includes labels for the bulbs such as Beauer TL150, standard 72W 60W equivalent LED bulb, Luxe Litemy T8 4W, and Luxe T6Y. The background is black with yellow accents and a yellow vertical banner on the right labeled 'Sunday'.

Liquid cooled

Our unique cooling system was developed to support Sunday’s unprecedented light output. Water-based coolant flows silently throughout the structure, with no need for maintenance, and does not need to be plumbed in.

Be in sync with
colour changing
output

Sunday features a colour changing light output, from bright daylight (6000 K) to a warm evening light (2650 K), enabling perfect synchronicity with the sun.

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.

Sunday can be set up for seamless, automatic adjustment throughout the day: coming on with bright, cooler daylight as the sun rises, transitioning to warmer daylight throughout the day, and finally dimming to very warm, lower light in the evening.

You don’t have to think about your light unless you want to - just enjoy it.

Install it anywhere

Sunday is as easy to install and use as any other chandelier. Our design principle was “a sunny day, any day, in any room.”

We recommend a ceiling height of at least 240 cm for the best effect. If you’d like to discuss how Sunday will fit in a specific room, please get in touch:
