I have decided to reduce module wattage to under 10 watts down from 13 to 15, driving at 350ma (max.400ma) I will have to add 4 more modules to compensate.
This will give me better top coverage, longer LED life and easier to regulate with a resistor. Of course I give up some brightness that would help with penetration.

My LED selection is based on what I have on hand, instead of what is truely optimal.
Each module will have
4 red K2s, R (second) bin.
1 k2 royal blue, Q (top) bin
1 SSC cool white, top bin
1 SSC blue, top bin.
Resistor to drop 1 to 2 volt.
I plan on using this for vegging to replace a 350 watt CFL array.
I will be playing around trying to flower. I will be adding a couple additional 2.5 foot long strips of red and far red LED during the budding period only.

I don't have high hopes for the budding and don't think it will replace HPS, but I would really like to trash the vegging CFLs and save a couple hundred watts if possible.
Do you guys think the LED color selection is close to optimal for vegging? I might be able to squeeze an extra red LED in, if real Vf's are lower then spec sheet.
I would like to start wiring LED modules this week.
