A '''large-format slide projector''' (also often called "large-format projector" or "large-image projector") is a kind of [[slide projector]] for [[large image projection]] which has a very powerful [[light source]] (up to 12 thousand watts using [[arc lamps]]). Therefore it is necessary to use a large slide format to protect the slide material from overheating during the projection process (even when the light is filtered to only visible light and the slide is cooled with strong slide cooling fans). Slide formats of 18 × 18 cm (7.1 × 7.1") or 24 × 24 cm (9.4 ×  9.4").
