The principle

What is an artificial window?

An artificial window is a wall-mounted light fitting that recreates the look of a real window: a landscape photograph, lit from behind by an LED panel and set in a bevelled frame that gives it depth. It brings a view and daylight-coloured light into rooms where no real window can be built.

  1. A flicker-free LED panelEven backlighting across the whole surface, with no hot spots.
  2. A printed landscapeAt 300 DPI minimum, on a 2 mm matt anti-reflective sheet.
  3. A bevelled aluminium frame53 mm deep, so it reads as a window reveal rather than a flat picture.

Artificial, fake or virtual window?

The three names answer the same need. Fake and faux windows usually describe a backlit picture like ours, while a virtual window more often means a screen playing video. Ours is a printed photograph: no pixels, no glare and no loop to notice.

The range

Two artificial windows, one format

Both measure 60 x 120 cm and share the same frame and image panel. What sets them apart is the light.

  • Classic artificial windowFixed 6,000 K daylight, 2,860 lm for 26 W. Dimmable over DALI or Bluetooth.
  • Circadian artificial window2,700 to 6,500 K across the day, 3,300 lm. Programmed at the factory and run from a Bluetooth switch, with no control cable to lay.
  • Side by sideTwo or three windows can be combined along one wall for a wider view, as in our Paris showroom.

Where it works

Where can you put an artificial window?

Anywhere a real window is out of the question. Pick a room to see how it changes once the wall opens up.

Interior and basement offices

A desk facing a blank wall is the situation we are called in for most. One window at eye level gives the room a horizon and a source of daylight-coloured light, without touching the façade.

Questions

Artificial windows, answered

What buyers ask us before ordering. Anything else, call the Paris showroom on +33 1 71 18 24 99.

Is there a light that looks like a window?

Yes, that is exactly what an artificial window is. An LED panel lights a landscape photograph from behind, and a 53 mm bevelled aluminium frame gives it the depth of a real window reveal. Once switched on, it reads as an opening in the wall rather than a lit picture.

What is the difference between an artificial window and a virtual window?

A virtual window is usually a screen playing video. Ours is a printed photograph lit from behind: no pixels, no blue screen glow and nothing that looks like a television. It is also designed to stay on all day, with LEDs rated for 50,000 hours.

How is an artificial window installed?

It hangs on the wall on the fixings supplied, or sits recessed in a plasterboard wall for a flush finish. Each window arrives pre-wired with a 2.5 m cable, and an electrician connects it to the lighting circuit. No opening in an external wall and no planning permission.

Can an artificial window light a windowless room?

It adds real, daylight-coloured light, but it works alongside your existing lighting rather than replacing it. The classic model gives 2,860 lumens at 6,000 K. The circadian model shifts from 2,700 K to 6,500 K through the day, following the rhythm of natural light.

Can we choose the view?

Yes. Choose from our catalogue of landscapes, all shot by the Cumulux photographer, or send us your own photograph at 300 DPI minimum. The image panel slides out of the frame, so the view can be changed later without replacing the window.
