I believe Reefbrite runs at ~50% max per LED (1.5W not 3W). So total is probably around 360w. Would love to see BRS report actual wall plug measurements though.
I think that is right. I believe they used to have a controller that would allow you to run them at 100% but I may not be remembering that correctly. It could be some just "hacked" into them and ran them at 100%.
