Try using this: to see how much PAR you will get with that LED setup. I did a quick try and it looks like you get about 40 micromols of PAR with 1000 mA current.
Interesting, I just played with that formula as well. The PAR values I calculated were significantly lower than what I expected, especially after talking with Rockhoe14er about his build.

I guess 65 degree optics are a go. I can always dim the LED's down to the desired intensity, but once I build the fixture there is no adding more light without serious adjustment.
