How long is your tube? Length of tube is relative to the maximum power out.
This table is good for maximum working current limits. Many of these are around 700mm and are really a 30W tube, so limit your current to the 15mA value.
The most simple way to do this and/or change values, is to use the Lightburn Edit → Machine Settings where you can load/save through the file system and read/write from/to the controller.
To do the RST=* command line entries, you need to use the Lightburn console.
