Bring the outdoors in,
even without a window
Take away the boxed-in feeling of windowless workspaces with our LED sky ceilings and virtual windows.
Our range comes in two families. A sky ceiling takes the place of a ceiling tile and opens the room upwards; a virtual window hangs on the wall and gives it a view out. Both come with steady daylight or with circadian lighting that changes through the day.
Backlit sky panels that drop into a suspended ceiling grid or hang from a solid one. Recessed sizes from 60 x 60 to 120 x 180 cm, plus round and square suspended models.

Ask us about itA hospital, an office and a care home each ask something different of their lighting. Our sky ceilings and virtual windows adapt to the setting and to the people who spend their day in it.
Operating theatres, imaging suites, windowless corridors: a calming sky above patients and staff alike.
Circadian lighting and sky ceilings that give residents' days a rhythm and bring calm to shared living spaces.
Treatment rooms, dental chairs, waiting areas: give patients something else to look at, and ease their anxiety.
Open-plan floors, meeting rooms, offices with no window: a breath of fresh air for your teams.

Our LED panels are easy to fit. Drivers come pre-wired, the modules drop into existing suspended ceilings, and every product ships with detailed instructions. Your maintenance team can handle the installation, or an electrician if you prefer.
Drivers arrive wired and calibrated. Simply connect the module to a socket or to your existing power supply.
T15 or T24 suspended grids, plasterboard ceilings, surface mounting or wall fixing: there is a solution for every setup.

A sky ceiling or a virtual window has a lifespan of around 50,000 hours.
At 8 hours a day, 5 days a week, that is roughly 25 years of use.
Every Cumulux product comes with a 5-year warranty covering parts and operation.
The warranty runs for 5 years for professional customers and 2 years for private customers.
It covers every component of our sky ceilings and virtual windows: the LED panel, the power supply, the switch, the raised frame and the printed image panel.
Power draw depends mainly on the size of the fitting:
Cumulux fittings use less power than a conventional LED panel, while offering far greater visual comfort.
