If you post the Specs I can do the Math for you ,
Also I would under drive the power supply by 25% of its rated power for its longevity.

great now I can get to the bottom of it.
1 cob draws 74 watts , 1.925A x 38.5V= 74
x12 cobs = 888 watts
`````````````````````````
1 Driver= 200w
200w minus 25% = 150w
2x cobs draw is 148 watts
One driver is *perfect* to power 2 cobs.
Six drivers for 880 watts is not to bad.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I am going to make a 3 Single 100w Full spectrum hanging cobs in the near future.
