It's not just "Haitz's Good Idea" it's "Haitz's Law"
Wow. ~15% increase in efficiency. SupraSPL I'd love to see a breakdown in your spreadsheet for these V.2 .Amazing. CXA3070 3000K AD [email protected] instead of old [email protected]. Gotta check if the SPD is the same after Champions league game.
SPD is the same as original CXA3070 -> 15% boost in efficiency. Nice.Amazing. CXA3070 3000K AD [email protected] instead of old [email protected]. Gotta check if the SPD is the same after Champions league game.
I think the price will be similar to CXA3070. It's been the same with XM-L/XM-L2, XP-E/XP-E2...Damn, this means I have to rebuild my lamps again. JK here is what we have so far in terms of "typical" numbers
If we assume a higher price for the CXB:

If we get a similar price:

So at 1.4A, 48% efficient, that is 10.8% more light/W and 12.5% less heat (and as GG pointed out a perfect match with the HLG-185H-C1400).
At 1050mA, 9.9% more light/W
At 700mA, 9.9% more light/W
So basically, 10% more bud
Hey! Don't you be dissing my Veros now!
And for us low runners... 20%!!! Do I sound stupid for wanting to upgrade? LolDamn, this means I have to rebuild my lamps again. JK here is what we have so far in terms of "typical" numbers

Apparently CREE has improved the current/tempVf droop so the CXAs can be run harder. That might allow the CXA3590 to compete against the Vero29 better at high currents.
While I agree more or less with your calculations ....
Please let me clarify a detail ,once again ...You make a good point SDS, of course I don't expect Cree to support the kapton method. So for you and many others the price of the ideal holder should be included when deciding between Vero and CXA (what is the price of the ideal holder?)
All that said, we have been able to get small quantities of Cree CXA3070 top bins for as cheap as $30 each (Alibaba) and CXA3590 top bins for as cheap as $40. I put the CXA3070s in the spreadsheet as $42 (Aliexpress). So there are some complexities when comparing based on pricing right now.
I agree the Vero2 would be a better comparison against the CXB3590. But I do not agree that the Vero currently wins by many points. But what fun would it be if we all preferred the exact same thing right? And finally, there is no guarantee that we will be able to get top bins of the CXB so the comparison might end up being theoretical for a long time.
...
Bottom end ?
Both of these COBs can yield same amount of happiness & satisfaction to a grower.
Cheers.
