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?

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.I wish I knew more about these new cobs
^ much respectI 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, 3618Looks like (to me) the New Vero is the best efficiency.
im guessing they digitized the spectrum from the datasheet....where did you get the spectrum data for that?
I underdrive my Cree cobs much more than that, but I think these will be more efficient and will still have the dimming option
Most likely GEN6Spec sheet from MFG vs spec sheet at Digikey.
Although looking today it seems maybe they fixed it
Spec sheet 160 lm/w
Digikey used to say 147 lm/w now says 159
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.
This says measured at 85Cthats 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
Yeah the CXB doesnt look to good with 105 lmwwell, sure, thats 55W
worth noting both CXB and CXM22 do better than the simulators would indicate in my testing.
cxb would not as they are 36v chips. 50v chips work best with that driverHow 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???
