light box: meaning, definition, pronunciation and examples

Both 'light box' (two words) and 'lightbox' (one word) are used. 'Light-box' with a hyphen is also common. In formal writing, check the style guide; often the two-word form is used for the general object, while 'Lightbox' (capitalised) may be a brand name.

They are largely synonymous. 'Light table' might imply a larger, table-sized piece of equipment used in professional settings (e.g., for large architectural drawings), while 'light box' often refers to a smaller, portable unit.

Modern LED light boxes emit very little heat and UV light, making them safe for most materials for reasonable periods. However, prolonged exposure of sensitive or antique items to any light source can cause fading, so caution is advised.

No. While both are boxes emitting light, a SAD light box (or light therapy lamp) is designed to produce very bright, broad-spectrum light that mimics sunlight, often with a diffuser and a specific luminance (measured in lux). A photography light box is designed for colour accuracy and even illumination for viewing transparencies.

A translucent box or panel illuminated from behind, used for viewing slides, negatives, or for tracing designs.
