I agree with @dr.h00k. TSL2000 can fit your tent and use for the flower stage.
We have no plans for COB. Most growers are now using SMD.
The old version of SP3000 has UV and IR, the current SP3000 does not. SP3000 can be used with a 4'x2' tent.
SMD are so much more efficient than COB it's old tech now. Would be moving backwards to use them
I would like to see mars bring back the UVA and IR diodes though. Just gives that full spectrum coverage. I know the PPFD is slightly lower but the overall spectrum is much better especially for bringing out those natural deep purple hues in the plants. I know that the warm light and white light does contain a small amount of the UVA and IR light but to have dedicated diodes on one of your large bar lights would be awesome.
Our FC&FC-E 3000 4800 lights have UV and IR. Not a large light, but also meet the needs of growing.SMD are so much more efficient than COB it's old tech now. Would be moving backwards to use them
Oooo I'd like to give that 4800 a try at some point. Maybe in a 4' X 4' tent. I could compare the fc8000 and see if the UV and IR make any difference!Our FC&FC-E 3000 4800 lights have UV and IR. Not a large light, but also meet the needs of growing.
One day maybe 
Looking great!!!My gal Loooooves her FC3000!
