We can plug those figures into an ohms law calculator.
We get: at 120 volts
So follow link this is what you have:

How many LED's and how many watts, we can divide 12 drivers into the number of leds, then you have how many LED's per driver.
Once you have that you figure, voltage in and out on one driver, that will be the volts of the LED's you can run.
710 milliamps will be the intensity at which they run.
Now you need to find a LED that fits into that box, no leds over 710Ma
And find LED or LED's whose voltage can be dived into the output voltage of the driver equally in whole numbers, as in 50 volts output from the driver you should be able to run two 25 volt LED's at a max of 710.
If I understand Growmau5's shit then this will be the plan for you.
