Your led look really good but in general, most have a bad design, I could build one with light bulbs and get better results and have(veg).
If I was you, I would spend 100's of hours designing a led, using a par meter, keep moving the bulbs till you have a par chart where the light cover the canopy perfect, say 4ft x 4ft at 18", every ft2 is receiving 600-700 par (no 1200 par dead center and 300 par on the outer edge, don't know what that is all about) so you have more bulbs on the out edge and less bulbs in the center, make your light very effective, per watt for the user.
Plaster your results all over the web, very low watt light covering a large canopy, you know it can be done.
may need a design simlar to a lumtek attis 300, with higher watt bulbs in the corners, you may not need any bulbs in the center 18" x 18"(add a 18" box fan in the space, that would be a real bonus or sell an an extra ) let that drop down to 600 par.
