A custom bespoke lightbox is designed and built specifically for the client brief it is responding to. The shape, dimensions, construction method, lighting specification and graphic treatment are all determined by what the application requires rather than by what a manufacturer has in a catalogue.
A standard LED display is a catalogue product built to a price point that requires compromises in construction quality. Those compromises show up under commercial use when joints crack, graphics fade and batteries fail. Boardsy products including their custom LED standing light box and ultra slim LED advertising board are both built from single solid moulds of PE plastic with no glued joints, carrying IP65 weatherproof ratings and UV resistant graphics rated for twelve years outdoors.
