Got my 320M with battery this morning, and it rocks! Love everything about it. On 1/2 power on battery it is less that 1 second refresh, no need for anything faster.
Another bonus for those that have not seen the battery, is how small it is, and the fact that you can plug 2 lights into one battery. So very stoked!
I have the quantuum R+ Dual Power and am very happy with it. I did not measure carefully the color temperature but I was not shoked by it so I guess it should not be ~3300K. I am very happy with it. I even had the good surprise to see that it go down to 1/32 instead of the 1/16 announced.
I like to be able to use it has a regular monolight directly connected on the wall to have fast recycling time, 150Ws modeling light and infinite pops. The only draw back is that it has the size of a regular monolight so it is not so easy to use on location than let’s say a broncolor mobile.
It actually supports 5 manual power flash groups A,B,C,D,& E allowing you to set manual flash power independently for each of those groups directly from the transmitter on camera (thats groups fired via radio signal with a receiver on each flash unit).
Catch is you need to use Mark II flashes to allow that.
