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.

Does the price of lightbox signs in Dumbarton include VAT?

No. Our guide range of £1,250–£4,800 per lightbox excludes VAT, which is added to the quote. The final figure depends on size, materials, access, removal of existing signage or graphics and the artwork needed, and we confirm it in writing after a survey or once we have checked your files.

When could work on lightbox signs go ahead in Dumbarton?

Fitting is typically scheduled once three things are in place: you have approved the proof, the materials are made or delivered, and any consent the job needs has been granted. For many jobs that is typically a few weeks from approval; illuminated or larger fabricated signs typically take longer, and consent decisions run to their own timetable.

Can the existing wiring be reused?

Often the existing supply, switch and timer can be reused, provided an electrician checks them first. New LED drivers usually replace the old control gear inside the box. If the circuit is old or untested, the electrician will advise before connecting to BS 7671.

Lightbox or lit letters?

A lightbox suits a logo, colours or extra information on one lit panel at lower cost. Individually lit letters give a cleaner, brand-led look with the fascia showing between them. Your street, budget and any conservation-area rules usually decide it.

What do you need from me to quote for lightbox signs in Dumbarton?

Photos are the most useful start: the whole frontage, window or vehicle, plus a close-up of the area involved. Add rough measurements, your logo or artwork if you have it, and the address. From that we can say whether a survey visit is needed and send a written quote, followed by a proof for you to approve.

Lightbox signs in Dumbarton

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.

Consent for illuminated signs in Dumbarton

A lit sign is the clearest case for applying first. Scotland's 1984 Advertisement Regulations treat illuminated signs differently from unlit ones, and express consent is usually needed for halo-lit letters, lightboxes and lit projecting signs. We check with the council before you commit to lightbox signs, then put together scaled drawings, photo mock-ups and lighting details, which you can submit via eDevelopment.scot or we can submit for you. Expect the council to look at brightness (PLG05 is the usual reference) and to prefer steady light, perhaps on a time switch. The mains connection is completed by an electrician to BS 7671.
