Description

Lightjams is lighting program for Windows that offers a free trial version. There is a Fixture Editor available. There was no information about the fixture format, but a forum member stated that they are saved in C:\ProgramData\Lightjams\Fixtures and uploaded them (mirrored here: fixtures.zip) – they are saved as xml and look pretty easy to understand.
