Yeah even if 6V it would (finally) good option for my Zebralights SC600...
100000 is a lot. But maybe talk to Simon, maybe he will eventually be interested in ditching xml2 T6 4c in favor of fc30.
Sofirn could also do the hi cri Q8 Pro version.
Skilhunt could put these leds in their headlamps instead of using the green 351d.
So many possibilities, but the producers will probably prefer to keep using the hi cri leds in 3535 size anyway.
Back to square 1…
Even Simon only orders a few thousand at a time. 100000pcs is a massive investment for what is essentially a gamble.
For 100 000pcs might as well ask nichia for a 3/6V 5050 B35A 
3v 5050 would be unique. 6v not that much. Kaidomain already have xhp50.3hi 5000K CRI90.
The data sheets looked promising (output, current handling, size) except for the binning possibility of it being under BBL. I understand the final product would be 9080 though. But as others have said, at 100,000 MOQ, we may as well wait this out and stick with the new xhp50.3 HI since they are already available in Hi Cri (not high R9 though, unfortunately).
but, with the direction things are going (cree with the xx.3 HI, and nichia b35x series), it looks like this is an exciting time for led development. I have cared less for necessity of 3volt over the last 6months, as I specifically seek out 6v / 12v lights & drivers now. Looks like some manufacturers are jumping on board with that too.
Still, I’ll order the samples soon so we can get them tested and whatnot, and if everything goes well on that side, I’ll do a smaller GB than I expected.
The train is certainly still going, but not at the same speed as before sadly.
Oh, great to hear! Thank you for all of this hard work BlueSword!
For reference, here is how the LED samples look and what base specs they have:
It turns out that to get the tint at neutral/below the BBL, they really needed to use these specs lmao.
Wait, I also noticed something: the LES is smaller than the B35AM.
This could actually work as a B35AM replacement in Convoy lights, and even be a bit more throwy.
But not R9080...read carefully
exactly. I thought the same thing as ifb at first. NOT the same though. that R9 will get ya everytime!
Also, while the initial GT FC40 was 12V only, this can be made to work in 6/12V, giving it more freedom.
Still not the 3/6V it would have ideally been, but it’s still an upgrade over the previous one, and it has a much smaller LES to boot, which means it’s a lot throwier than the GT FC40.
Funny thing is that the specified LES is smaller than the B35AM, and since it has a DTP, perhaps it’ll be able to replace the B35AM in Convoy lights for example.
Ok, I also discovered something else: the emitters used in the GT-FC20 and GT-FC40 are the same, while the GT-FC30 and GT-FC60 use the same emitters as well, and they’re more efficient to boot.
It might actually explain why the GT FC40 wasn’t that efficient, even for a high CRI emitter: same LES as the higher power higher end FC60, but different lower class emitters.
Cree datasheet does not state r9, so we will need to wait for some independent test. Maybe they are R9080. There’s also a 95CRI 5700K,but still not available anywhere.
Typical R9 values for Cree 90CRI LEDs
Might be more viable to have 6V drivers produced for some lights, no?
So probably not R9080 
So, question: would anyone be ok if I ordered an FC60 to test out the efficiency difference vs the FC40? I have an FC40 M21B on the way, so I think testing the efficiency difference vs the FC40 would be great.
The difference between the FC40 and FC60 are the same between the FC20 and FC30: better higher quality more efficient emitters that can handle more current as well.
Excellent news: we still have some hope regarding the 3V 5050 LED!!!
The GT FC15 exists: it’s a lower power apparently 5050 emitter in the same class as the XM-L2 instead of the XHP50X.
I’ll ask them yet another question, because a drop in XM-L2 3V domeless R9080 replacement would still be awesome.
PLEASE DO! I’m very intrigued. More efficient FC40’s would be awesome.
Look into that as well! Thank you for doing all this digging! This is great!
