I would say that is pretty good, best way to find out is rent a par meter just to make sure. I had a ai prime on my biocube 32 with the shorter flex arm and it had perfect spread and par. (Not sure how high it was from the water)
At 13 inches you're getting too much light spill out of the tank. Drop to BRS recommended height. Your spectrum looks within recommended ranges, but I just noticed two things. First, your running the overall intensity just over 40%. Use two fingers on the screen when in edit mode and slide up . This will adjust your blend equally. Do this a little at a time though so as not to stress your livestock. Also, 14 hours is a really long photoperiod. 8-12 is recommended.
