A lightbox is an electrically-lighted sign that contains the mechanism to encapsulate, suspend, protect and display a discrete sheet of backlit film which embodies a print image, and which is designed to transmit light through the film for increased image brightness, contrast and color saturation.

What is the difference between electic sign and electric light box

Just by the names, you can see why there’s some identity confusion between the two products: (a) Electric Signs – or more definitively, “electrically-lighted signboxes”; and (b) Lightboxes for backlit graphic display.

Customers shopping for one or the other often interchange these phrases and similar, when referring to a related product. So the question is, is there really a difference between an electric sign and a lightbox — and if so, what is it?

The term ‘electric sign’ has been in use since at least the early 20th century, when roadside commercial signs powered by filament-electric lamps began to appear. And pragmatically, any product that can be categorized as a ‘sign’ — as long as it is powered by electricity — can be thought of as an electric sign.

Alternatively, the term ‘lightbox’ came into common use about the middle of the 20th century, as lighted cabinets that hold and display a sheet of backlit graphic film began to appear in commercial and retail environments.

Therein lies the defining difference between a an electric sign, generally — and a lightbox, specifically:

A lightbox is an electrically-lighted sign that contains the mechanism(s) to encapsulate, suspend, protect and display a discrete sheet of backlit film which embodies a print image, and which is designed to transmit light through the film for increased image brightness, contrast and color saturation.

So technically, the electric signs category is by definition a superset of fixtures that includes lightboxes as just one type. But in practice in the signage industry, the phrase ‘electric signs’ is often intended to exclude the subset of ‘lightboxes’, simply by describing any electric sign that does not fit the narrower ‘lightbox’ definition.
