I've gotten the kit set up with a meanwell 240W, 50V driver. Using 16 LEDS now (8 of each). I have an extra 4 but haven't used them yet. Using about 900mA per LED.
Seems brighter, but tank is having to adjust and CO2 and dosing weren't running right (good enough for 3 old 55W CFs, problems showed up when going to ~170W of LED).
Sitting about 6" over water using the square tube heat sink w/ forced air cooling. Quite warm, but could leave finger on for a while w/o burning (10+ secs).
