Why does our old lightbox flicker?

In an older box it's usually failing fluorescent tubes, starters or ballasts, and replacing them one at a time rarely lasts. Patchy light can also mean water has got in. Converting the box to LED fixes the cause, if the frame is sound.

Do lightboxes let in water and insects?

A well-made box is sealed around the face, with small drainage holes along the bottom so condensation can escape. LEDs run much cooler than tubes, so less heat draws insects in. Taking the face off occasionally to clean inside keeps the light even.

Can the face be changed later?

Yes, which is one of the main advantages of a lightbox. Flex faces unclip or untension and acrylic faces slide or lift out, so a new design can go in without moving the box. Keep the face dimensions from handover for easy reordering.

Is there a typical lead time for lightbox signs in Cardiff?

Yes, though it varies with the job. The lead time typically runs from the day you approve the proof, not from the first enquiry, and is typically a few weeks. Survey visits, artwork changes and any consent application sit before that point, so getting photos, sizes and logo files to us early typically shortens the overall timescale.

Who carries out the work on lightbox signs in Cardiff?

The work on site is done by installers working under our contract, and anything that needs making is produced by specialist fabricators. You deal with Smart Signs throughout: we take the enquiry, survey, prepare the design and quote, check consent and coordinate the fitting, so there is one point of contact from first message to handover.

Will the location in Cardiff affect the cost of lightbox signs?

Location is one factor among several, alongside size, material, access equipment and design time. Our guide range is £1,250–£4,800 per lightbox + VAT; any travel, parking or access costs for your site in Cardiff are included in the written quote we confirm after a survey or artwork check, so you can see them before you commit.

Lightbox signs in South Glamorgan

A lightbox sign is a shallow enclosed box with a translucent face and LED lighting inside, so the whole panel, or just lettering routed into it, glows evenly at night.

Why choose lightbox signs in South Glamorgan?

Taking over a franchise or a new lease in Cardiff? A replacement face keeps the existing box and wiring.
Where a Cardiff shop has a long fascia, a flex-faced box spans it without the joins rigid acrylic sheets need.
If a Cardiff convenience store or pharmacy has a sound box frame, a new face refreshes the frontage for less.

Consent for illuminated signs in South Glamorgan

Wales has its own advertisement regulations, and a lit sign is the case where they matter most. Internally illuminated, halo-lit and lit projecting signs typically need express consent, and on listed buildings or in conservation areas the council is likely to look closely at size, light levels and fixings. Keep illumination static and moderate; PLG05 from the Institution of Lighting Professionals is the usual reference. LED modules and drivers run at low voltage, but the mains connection still needs an electrician working to BS 7671. We check before you commit and can prepare or submit the consent application.
