Hi,
@ uzerneims, in europe there are digikey and newarks and mouser. 30euros for the Cxa3070 Z2 3000K.

Yep by my measure, the CXA3070 3000K Z2 @ 1.4A is 36.6% efficient and the Vero 29 3000K @ 1.4A is 35.8%.Have you checked the availability of Bridgelux vero chips? The 29 is comparable to the 3070.
I really like the 95 3000k! how can we order those? What bin code?

The high CRI top bin is very impressive, but it still holds true that it is really just a low cri with a "filter" over it, blocking photons. The 80 cri is creating 12% more photons/W.
The Oslons are not a bad idea speedyg if they could be put on the same sting as a 3070, I guess that would depend on the driver and current but then there would still be some "disco" effect happening.Totally agree on that too, epicfail...
37% is already the efficiency of an HPS, but the spectrum is better, the repartition is also better and penetration can be manage by using lenses...
But why not adding 10w of oslon SSL hyperred on your 3000K 80cri => you catch up with the 650nm+ of the 93cri plus you will be more efficient.
is vero 29 4000k is better for flowering than for vegetative state?Yep by my measure, the CXA3070 3000K Z2 @ 1.4A is 36.6% efficient and the Vero 29 3000K @ 1.4A is 35.8%.
The Vero 29 4000K might actually be a good choice for flowering because it has 13% blue. The Vero 3000K has 8% blue and the CXA 3000K has 10% blue.
Btw do you think adding blue to a mix of 8W oslon and 52W cxa 3000K would be necessary ?
I mean would it be better to veg with cxa + some blue, and flower with cxa + some red?
It's true that the high CRI has more far red, on the other hand most of this >700nm light is (imo) wasted energy.I cant help to notice that the purple line seams to have close to the same amount of "blue", about the same amount of 640nm and more of everything above 650nm.
The Vero 4000K vegs very well when the intensity is high enough. For lower intensity the 5000K is a better choice. For flowering the Vero 3500K and 4000K both are superb.is vero 29 4000k is better for flowering than for vegetative state?
How well do you think the 2700k vero's would work?It's true that the high CRI has more far red, on the other hand most of this >700nm light is (imo) wasted energy.

Btw I'm curious why no one has ever tried the CXA 3500K for flowering.
