I wish I knew more about these new cobsVero's 3K LER is 321 , so 160 l/w = about 50% eff
Any idea the LER of the Cm22 3k?
Luminus CXM-32 Gen3 the next big thing??

I quickly digitized the spectral distribution. According to my PSQC calculator the CXM-22 3000k 80CRI has a LER of 323 lm/W. This spectrum is identical to the CXM-32 3000k.
See the output from the calculator below...

72V vero is in same class as cxm32, 1825, 3618
36 and 50V vero is closer to cxm22, 1818, cxb3590

im guessing they digitized the spectrum from the datasheet....

Yep, the warm white is the one I digitized. I assumed that that was the 3000k. I'm going to try the 90cri as well.

Heres what I was referring to with wrong specs on the GEN7 Vero

thats the identical number that the vero excel simulator returns for the 85C hot-binning test conditions listed on the digikey spec
at same wattage and case temp, according to the calculators
1825= 144 lm/W
3618 = 145 lm/W
cxm 22= 120 lm/W
cxm 32= 145 lm/W
vero B 50V= 140 lm/W
vero D 36V=130 lm/W
cxb3590 = ~ 105 lm/W
at same wattage and case temp, according to the calculators
1825= 144 lm/W

Yeah youre right Vero rates at 25*C, but Digikey to keep it fair shows same conditions for all brands 85*C
Kinda changes how I feel about the Vero

Yeah the CXB doesnt look to good with 105 lmw

How would two of your CXM22 G3 engines that you currently have on pre-order pair up with a HLG-120H-48A? According to the driver's page, dual cree (or citizens) would be running in the high 70W range. Would I be looking at the same output running CXM22? Jesh if so and considering your sale on that particular driver, that's right around 150W for $120???

cxb would not as they are 36v chips. 50v chips work best with that driver
2 would work, 3 would be more efficient with those heatsinks
