Man thank you SO much for clearing that up , it shares the amperage when wired in parallel ,gotcha . And the reason I say it seems it's runnin "soft" is as you've mentioned there running around 85 watts per board I think the max for the boards are like 160 ish? Yes I do have a dimmer hooked up to it but even with the dimmer at 100 percent the boards are only being used at around 50 percent when I have 4 going off that one driver ,right?at one point during the build I had only 2 boards hooked upto the hlg3202800 and I stepped out as my partner finished wiring the other 2 up .. when I came back the next day and all 4 were now running off the driver my first thought was hmm doesn't seem nearly as bright.. my partner who had done the wiring said he thought it was the same , (his poor eyes couldn't tell) makes sense now as the boards went from 1400 milliamps /160 watts per board with 2 on that driver to 700 milliamps per board with 4 according to what you are saying correct ? So I guess 2 304s off a hlg 320h 2800 is basically running them at /near there full power ? And with 4 your running the boards weaker but you're spreading it around to cover a larger footprint?
