Lightwright is a proprietary software that manages theatrical lighting data and paperwork.

Developed and maintained by John McKernon, the Lightwright software combines a relational database with a graphical user interface in support of user generated instrument schedules, channel hookups, and other lighting paperwork from a single spreadsheet/database.

[1] The software is widely used in the production of Broadway and other live entertainment shows, and across a number of educational and arts institutions.

Lightwright 2.0 was released in January 1995 for both Microsoft Windows and MacOS, and written in Visual Basic and ZBASIC respectively.

The subsequent two versions—Lightwright 3.0 (1998) and Lightwright 4.0 (2003)—were maintained using separate code (Visual Basic / ZBASIC) for each operating system.
