Lightwright is a spreadsheet/ database program created specifically for theatrical lighting applications. The program is used to sort and manage data related to lighting designs and to generate design paperwork. It has been used to create and manage the lighting designs for hundreds of Broadway shows.
Version 5 was released on September 1, 2009, and as of January 20, 2010, Lightwright is being used by every Broadway show currently running.
Lightwright is not a drafting program, but rather a database program similar to Microsoft Access which has been tailored specifically for stage lighting. The program allows a user to input information about lighting units such as type of unit, location, purpose, color, channel, circuit and dimmer. The information can then be displayed or printed out in a number of different formats that can be used for hanging the lights ( Instrument Schedule) and cueing the show ( Channel hookup).
Version 5 shares exchanges data automatically with Vectorworks' Spotlight 2009 and later.
The program was created by John McKernon, and is distributed by John McKernon Software.
The program won the Lighting Dimensions International Software Product of the Year award in both 1998 and 2003. In 2004, it was honored with an Eddy Award.
