Light boxes for façades, shop windows and interiors.
A light box is an internally lit box with an acrylic or tensioned banner face. It keeps the brand readable by day and by night. We make backlit and frontlit boxes to the size of the space, for façades, shop windows, shopping centre walkways and shop interiors. We install across Greater Lisbon.

What does it include?
Face and image
Opal acrylic with vinyl applied, or a printed tensioned banner, with the brand colour checked before the box is closed.
Frame and LED
An aluminium or sheet-metal frame, LED modules spread to light the face without hot spots, and a power supply sized for the piece.
Measuring the opening
We check the size and the power feed before production, so the box fits where it is going.
What changes the price

frequently asked.
What do people ask before deciding?
How much does a light box cost?
It depends on the area of the face, how many faces are lit and the way it is fixed. Send a photo of the site and the size of the opening on WhatsApp and you get a fixed quote the same working day.
What is the lead time?
The lead time runs from the approval of the design and is written into the quote. The warranty on the box and on the lighting goes in the same document. Large boxes, or boxes at height, depend on access to the site.
Does Litoral install?
Yes. The box leaves the workshop assembled, and the same team fixes it and wires it up, anywhere in Greater Lisbon.
Do you do site visits?
We do, when the opening is irregular, the fixing is not obvious or there is no power feed. Otherwise a photo and the size are enough to settle the design.
How do I pay?
By Multibanco (the Portuguese debit network), bank transfer or card; businesses can ask for 30-day invoicing. The terms are written into the quote.
Do I need a council permit?
A light box on a façade, or projecting over the public highway, may need advertisement consent from the city council. In Lisbon, it is the Câmara Municipal de Lisboa that licenses outdoor advertising. We say in the quote whether your piece needs it, and we handle the application with you.
