.lw4 File Extension

Developer: John McKernon Software
File type: Lightwright File
You're here because you have a file that has a file extension ending in .lw4. Files with the file extension .lw4 can only be launched by certain applications. It's possible that .lw4 files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .lw4 file?

Theatrical lighting is not an easy task, which is why there is a program called Lightwright used to manage paperwork related to theatrical lighting. The software creates documents known as LightWright files and these documents are attached with the LW4 file extension which is why they are called LW4 files. LW4 files are saved in a unique format as the format consists of a cross between database and spreadsheet formats. These files contribute a lot the management of theatrical lighting or the function of the LightWright application since these files can contain 30,000 lights, 62 DMX universes, six different control systems as well as 32,000 dimmers. These documents refer to the paperwork used and are necessary for professional lighting design management. These files make it easy for users to manage lighting through the LightWright software. LW4 files as well as the LightWriught software were developed by John McKernon Software and categorized as data files.

John McKernon Lightwright

Lightwright was the creation of John McKernon, a professional lighting designer who taught himself BASIC and Z80 assembly and wrote Electric Assistant, which was the predecessor of this industrial lighting design software. Lightwright combines the features of spreadsheet software and a database management tool. Because it's specially designed for use in lighting design, this hybrid program understands that dimmers and circuit lamps need low-voltage current and that strip lights consist of different colors. Actually, the application is not a drafting tool or a diagram creator. Professionals use it to designate the placement of color scrolls and moving lights in a design plan and automate the lighting schedule for turning on/off lamps at a specific time. Apart from management and planning, Lightwright's features also include organizing the designer's notes, figuring out the circuitry of for more efficient lighting, rearranging channels, and reassigning dimmers.

a word of warning

Be careful not to rename the extension on .lw4 files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .lw4. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
