Hello there,
I'm Felix from the Open Fixture Library. We collect fixture definitions in a unified format and these fixtures can then automatically be exported into various formats of lighting programs or consoles. We've just released the ColorSource plugin, this means you can download all 363 fixtures (rising number) as .jlib files now!
Anyone can add new fixtures via our online Fixture Editor and the whole project is free and open source.
Feel free to have a look at the website, browser our fixtures or maybe even add a new one :)
