Driving the DMX light things is pretty easy although being creative is a matter of opinion... The hard part is when things don't go as planned and then finding out what is misbehaving, and with some fixtures that can be quite an ordeal...
I'm working on a $2.5k 150W LED moving head DMX spot with selectable gels/gobo's at the moment and it's proving to be quite the challenge (and with the covers off is often blinding) to fix. Lets just say the onboard controller is giving me an attitude problem with the fixtures errant mechanical and electrical behaviour...Things like focus, gobo alignment, gel selection, X & Y trim, motor & LED temp & current settings, and cleanliness are just some of the things to be examined... The 55W little brother I worked on just prior was a walk in the park by comparison...
