I should have updated. I had shipping Monday morning and the light by Wednesday at noon. I've been running it since then and WOW is it much brighter at comparable settings and it spreads the light MUCH more evenly. I'm still trying to kind of get a figure for the setting to put it on. Much higher than 6 and it gets a little warm, and I'm following the guidance of leaving it 15" from the ceiling of the tent, and I have a fan pointed at the driver but it's a crappy little fan. I may need to try a bigger fan if I want to turn it up much more.
One thing: I replaced my 200w AC Infinity QB, but I also had their supplemental lighting bars vertically on the tent corner bars and I wasn't able to tie these together the way I was able to before, so I've lost these for the time being, but I feel like their way less necessary now that I have a much better coverage. What I don't want to lose is overall light output though, so I'm trying to measure how to get back to about where I was, without putting off too much heat.
I know about how much wattage I was using with the old light, and I've got an estimate for the wattage I'm using on the new light- or is that not an apt comparison? If I have more questions, I'll start my own light thread and not further jam someone else's up.
Thanks again for the help on my light journey!
