Assuming you've selected the appropriate
fixture profile in patch, the lamp controls are in the About section. Select you're fixtures then hit the About
button, Lamp Controls are on the lower right of the CIA. This is assuming you're running v1.8 [or later] of the OS. In v1.7 and before, Lamp Controls is a
softkey. For v1.7 and before, hit the More Softkeys
button, then S3 I think.
