as long as the sign was made for flat faces
The main thing to keep in mind is that the faces need to be far enough from the lights so that you can't see the outline of the lights. Pan faces are made so that the frame does not have to be as thick as you would need for a flat face. 3" is pretty much the minimum distance.
