That's also what I was thinking that only 8 XM-L's would be on the weak side. 
 
I currently have 2 meanwell ELN60-48D drivers, 13 XM-L T5 cool white leds, 5XP-E Royal blue and 5 XP-E blue so I'm going to have to place an order somewhere regardless as I don't have enough components for a complete build. 
 
When I originally ordered the XM-Ls, I didn't realize they had a max drive current of 3000 mA.  Otherwise I wouldn't have ordered those particular drivers as they can only push 1300 mA. 
 
Seeing as I'm going to need to order at least one more driver and several more LEDs, I may end up trying out one of the aquastyle kits and save the XM-Ls and meanwell drivers for a retrofit on my 225 gallon reef once some snow starts to hit the ground.
