A unit is a term often used interchangeably with light source.
In lighting work, a unit is a term often used interchangeably with light source, referring to an individual lighting fixture or instrument. A crew might speak of adding a unit, moving a unit, or powering several units, meaning the fixtures themselves. The word is a convenient, general way to refer to a single piece of lighting equipment without naming its specific type.
Because a unit is simply a fixture, it draws power and is often dimmed and controlled like any lighting instrument. Referring to fixtures as units is common shorthand in production lighting, where many instruments are rigged and operated together.
Each unit depends on stable power and, in many cases, control wiring to deliver consistent output. The power and control cabling feeding the units must be rated and configured for reliable operation.
