hey hoppy. love your work, the led guru. i would like to upgrade my led fixture. i have done a DIY one before and thanks for your help on that one. at the moment i am i am running 12 cree XML-t6 at 700ma. what i was thinking of is buying 2 of these http://www.rapidled.com/mean-well-lp...urrent-driver/ and running 9 of the cree xml-t6's of each of these and building the heatsink myself. this is going over a 4 foot med planted 60g tank, dosing dry ferts and co2 injected.
what i wanted to ask your help on is
1. is there a better driver out there that i just cant seem to find that will save me from having to wire up 2 sets of 9 at 1750ma
2. is this going to be overkill on the lights?
3. what would be the best way to arrange them. i was thinking two 4inch wide heatsinks running the length of the tank. if the tank is 18inchs wide then one running say 6inchs from the front and the other 12 inchs from the front.
