This is how I am reading it as 400
Generic 100W COB warm white: 2.557A -> 90.5W -> 329lux/W (sickly yellow/green color temp, but it is warm white technically)
Vero29 3000K #1: 2.556A -> 101.5W -> 429lux/W
Vero29 3000K #2: 2.54A -> 101.5W -> 423lux/W
CXA3070 3K AB #1: 2.165A -> 86.75W -> 455lux/W
CCA3070 3K AB #2: 2.21A -> 88.5W -> 433lux/W
CXA3070 3K AB #3: 1.996A -> 80.16W -> 469lux/W (This is the most efficienct CXA I have come across, but has a higher Vf than any other CXA also, just an outlier for reference)
Although the CXA has more lux/W, the Vero may actually have just as much power output/W because more of its output is in the red/deep red range. The CXA consistently has a higher Vf so the driver reduced the output unfortunately. But I can dig out a 2.4A driver that can go up to 45Vf if this data is unsatisfactory.
Here are some lux/W measurements I just did, pulsed at 25C, distance from COB to luxmeter ~12". I measure power dissipation directly with a pair of multimeters and that is taken into account in the lux/W figures.Haven't actually measured with a lux meter ,but to my eyes the difference in brightness ,
between a VERO 29 and a CXA3070 Z4 bin @ 2200 mA ,is quite noticeable.Maybe more than that .
The Vero 29 really seems to be outputting much more light ...And ,trust me ,it's not just me saying that ,is plenty of people
,close friends and relatives ,suggesting same,when witnessing the comparison ...
