I suppose I will use 1400a and make sure I use the dimmer depending on how they are doing. So if I add co2 later on I can get enough power to the cobs.
What is the efficiency rating for cxb3590s at 700a/1050a/1400a/1750a I can't seem to find them with Google.

Does not have the 1.75 amp but has the others. Study this chart there is a lot of information here that matches the cob.
look for:
3500k
36v
cd bin
cxb 3590
If you understand this chart you can find all kinds of other charts so you can compare different cobs.
Also you see that 4.65 we used to get the PPFD earlier.
