But when it comes to choosing between something like Vero29 running hard versus CXA running soft, the increase in efficiency is not as extreme as when switching from HPS. That is why I recommend most growers run their CXA3070s and CXB3590s at 50W each. Here is how it compares:
Vero 29 running relatively hard
Vero 29 = $28
Alpine11 = $10
2.1A driver HLN-80H-42 $45
total cost $83
79W @ 37.3% = 29.5 PAR W
$2.81/PAR W (driver efficiency is 91% vs 94% for the next examples)
CXA3070 running mid:
CXA3070 AB $120
Alpine11 $30
1.4A driver HLG-185H-C1400 $70
total cost $220
156W @ 43.3% = 67.5 PAR W
$3.26/PAR W
CXA3070 running soft
CXA3070 AB X8 $320
Alpine11X8 $80
.7A driver HLG-185H-C700 $70
total cost $470
196W @ 50.4% = 98.9 PAR W
$4.75/PAR W
CXB3590 running mid
CXB3590 CB X4 $240
Alpine11X4 $40
.7A driver HLG-185H-C700 $70
total cost $350
195.6W @ 51.7% = 101 PAR W
$3.46/PAR W
CXB3590 running soft
CXB3590X6 $360
Alpine11X6 $60
HLG-120H-C350 $65
total cost $485
143.4W @ 58% = 83.2 PAR W
$5.83/PAR W

Damn, this means I have to rebuild my lamps again. JK here is what we have so far in terms of "typical" numbers
CXA vs CXB 3070
If we assume a higher price for the CXB:

If we get a similar price:
View attachment 3354035
At 2.8A, 16% more light/W
At 1.925A, 13.8% more light/W
At 1.4A, 10.8% more light/W, 12.5% less heat (and as GG pointed out a perfect match with the HLG-185H-C1400).
At 1.05A, 9.9% more light/W
At .7A, 9.9% more light/W
So basically, 10% more bud
