As I am both a designer and technician, I understand the need to put lights in crappy places, but understanding of the need to take time to focus them safely and properly when I'm the LD on the deck and not the electrician on the ladder. That said, as a technician, I tell the designers I work with to put the light where they need it. Exactly why I default to the pan bolt/set screw, but have no problem going to the yoke bolt if need be. Lights will end up in weird positions like on a 37 degree diagonal, but lack the proper hardware to hang them straight. I've had to pan units via the pan/set screw, yoke bolt and Clamp Bolt; while having half my body though an extension ladder. Thus, why I don't expect technicians to do anything I would not do, or to do things exactly how I would. I will make suggestions as either a designer or technician based on my experience in a space, but I don't try to force technique on anyone.
