Dallas, you are so right!! 
I spent too much time on my knees crawling around working on electronic equipment. I even laid on the cold concrete floors and steel grates so I could see what I was doing on equipment mounted 6 inches off the floor. I hurt my shoulders reaching above my head as well, when I couldn't climb into the cable trough. When I was 51, I moved into engineering, and I always tried to design equipment to be mounted above the knees but no higher than eye level, just to help the guys out. (It was kind of like mounting the equipment in the strike zone!!) 
Now at age 65, I wish I hadn't had to crawl and kneel so much! 
Sorry to digress, Garrett! I never want to stop encouraging middle age guys to think like you are in getting off the floor. All of your spotlights look great! Excellent layout.
