Build is pretty much complete, just need to cleanup the controller wiring. I also added in a DS18B20 temperature sensor (Plan on adding a couple more for my DWC water temps + air temp).
One n00b mistake I made was not accounting for the efficiency drop of the AC/DC PSU. This limited my overhead and is pushing the Wattage over its rating at full 1000ma. At ~900ma they are running @ 429W. Could probably bump them up a bit, but going to burn them in at this.
After running an hour @ ~900ma and they are measuring around 48C on PCB surface next to LED and 41C on the backside of the Aluminum sheet (measured by DS18B20).

So I think at 900ma they are running 156lm/w @ 45Vf = 40.5w = 6318lm x 9 = 56,862lm
