Thank you for requesting the fixture you have.
Unfortunately, the fixture, CHUVET Intimidator Spot 255 IRC, is not supported by rekordbox lighting.
Please see the top of the lighting fixture request page from the link below.
Only specific DMX lighting fixture features – such as the dimmer, strobe, color and moving head (Pan/Tilt) – can be controlled with [LIGHTING] mode.
The fixtures, which have other features than the above, may not work as expected. Features like Gobo, along with some effect lights, lasers, fog machines and all-in-one lighting systems aren't supported.
