What driver do you recommend for C8, 1x Luxeon MZ, Fet switch?
Depends on what you want, max. output light, or light for general use, so max. current can be anywhere from 3Amp to 15Amps. 12Amps looks like sweet spot for hot rods.
C8TT head build with CUTE-4-SS optics,4x Luxeon V 4000K, 24Amp LD-B4 driver and subZero FET switch:

Sorry if I mixed something up here. I assumed there is a LD4 driver planned with e-switch firmware on it to work with the C8F.
I asked some months ago here: https://budgetlightforum.com/t/-/46929/418
I remember someone asked, well good news is that I will finally start with driver design upgrade and new firmware .This will take some time,but I think it will be worthy.
Thank you Neven! That's good news indeed. :)

Luxeon MZ 5700K 90CRI (9080 Nichia rating) are finally here, flux bin is R!
Maukka tested MZ LED from Mouser before, it seems Mouser's reel is either high P bin,or low Q bin.
1 bin up from the koef3 test. :+1:
With the MZ available, I guess it is time for a new Q8 version then! 
RIP djozz’s Sofirn Q8 before it even arrives.
I trust more to Maukka's test since he has much more professional equipment.
He measured 805lm @2800mA,~25C, datasheet says lumen output at ~25C is ~6% more than at 85C, which means light output @85C for that LED would be ~760lm.
So that LED from Mouser is either high P bin, or low Q bin.
I will send sample to Maukka for lumen test, just to see where within R bin this reel is.
With this R bin, most single MZ builds should be capable of ~3000lm OTF of crisp white 90CRI light at 15Amps.
Any updates regarding this? I want to put everything into one order.
Most spacers should arrive tomorrow (they should arrive last week,but delays as usual), FET switch is in final phase of testing(firmware is finished),I need to make lisitngs for everything,so you can count on the end of this week for all.
Man this is exciting. You got one of the most interesting drivers already, but I’m just spoiled by e-switches. :innocent:
ANNA6 + 21700 C8F spacer + 20mm e-switch l4p driver we hope for the not too distant future
I’m also waiting for an e-switch driver.
Not in a hurry though, but i need one for my Sofirn / Convoy C8 triple.
Don’t want DD FET driver.
Spacers arrived today.
Nice.
What about the 30A drivers? It’s hard to stay patient :).
You mentioned before that 18AWG wires were the thickest that fit through the hole in your drivers. Can you tell me the actual outer diameter of the those wires including the insulation that you tested?
There’s a company here in Germany which sells wires with an especially thin silicone insulation.
Another question: will you put a specially prepared spring on the FET switch and 30A driver so they actually work with 30A and the voltage drop is kept small?
