Yeah, I just used one ab800 superclamped to the second story track railing of the gym and pointed it towards the foul line. I will take a pic of the setup tonight if I remember when I'm there for a boys game. The mark III has a kelvin function for wb, just as you described...messing with the wheel per 100.
OK, that's what I thought with the Kelvin adjustments. I do that too, but I'm not throwing as much light as you. Cool. Thanks!
