as for running jumpers external to the light, I would have to recommend against it, as you are exposing the ground, which can cause an electrocution hazard.
I completely understand that PCB must protect against liability with this advisement, but I am more than willing to assume the risk to avoid several others:
For the last five years Einsteins were my "Grab Your Lights and Go". When I am outdoors, I usually move around.
I have had CSXCV's fall out - luckily into my cart so they were not lost. I have banged an Einstein against a tree - almost directly on the CSXCV. I was amazed both still worked and that the card was not completely snapped off. Never the less, their protrusion is a risk for breakage. I have nearly forgotten CSXCV's when leaving the studio to go on location.
When in studio, I frequently have an Einstein on a drop pin on a boom. As you know, that usually puts the light in an upside-down position. One day the CSXCV on that light had fallen out when I was not around. Luckily it was not stepped on, and also that I managed to find where it had bounced under a cabinet.
And, as mentioned by others, it just saves time. It may not seem like much to some, but I've got a bunch of little things I do to save setup time, and together they make a difference.
