I use a similar output per sf. I use 400w cobs with 48w -Deep Red, 48w IR, 48w-Far Red and 48w-Royal Blue for veg and I see better inter-nodal growth and healthier growth in vegetative stage, and more stretch, and quicker growth with sunrise/sunset Deep Red/Far Red timing. I assumed you wanted to know the general layout of the fixture. Those diodes also needs lenses to improve focal plane and point, and there are three channels for CillLed Red/Blue/White. My layout is based on most professional grow lights and NASA research. I use my own controller, GrowGreen like ChilledLed does to control each channel of colors, I use six channels 2-COB channels and 4-Color Diode channels with a 48v power supply similar to the Canopy ten model before Growmau5 revealed his light. I listened to others and came up with my own best light for me. You decide what is best for you and your grow and you can do the same. If you want a light buolt like someone elses, just get that light and grow. I hear ChilledLed is selling that 400w model on discount and in a group cost model too.
