When trying to calculate the maximum lumens based on other lights, you have to multiply by the lowest common denominator or by the limiting factor. So it might be better to think of 23000 lumens per 4 x 18650 batteries. Or better yet, 33A at 6v per 4 x 18650 batteries.
Keep in mind that an xhp70.2 can potentially do 9k lumens. So in theory three of them could do 27k lumen. So if we’re only getting 23k there has to be something restricting it. In this case it’s the batteries.
The MF03 uses 8 x 18650 which in theory could provide 66A at 6v. If we spread that over 8 xhp70.2 that is 8.25A per emitter. 6,300 lumen x 8 = 50,400 lumen. So even though 8 x xhp70.2 could do 72k lumen in theory, I think 50,400 lumen is the maximum possible for 8 x 18650.
Knowing that Astrolux doesn’t normally build FET drivers, especially not high end ones like TA builds, nor do they typically bypass springs, etc… I am actually expecting 30k lumen or so from the MF03.
Lexel has said he can probably build a dual driver for this light, so maybe we can expect to see over 40k lumen from that. Maybe 45k?
I was asked from Neal 3 week ago if I can make a driver for it, he is in contact with Matemineco
The plan from my side is to go to 51mm 5 battery carrier in series to have enough voltage overhead to 12V max. 30A Output, so about 385W for the LEDs
This would mean 6V 7.5A per LED and roughly 6000 LED Lumens with P2 binning
Then the MCPCB 2 XHP70.2 6V in series so we have 4 groups of 2 LEDs at 12V
XHP35 also has full regulated output till the batteries are drained this way
I was just gived 50mm driver diameter, not much else to work on and Neal sendy me a prototype
Not sure if this will happen but I already spent aver 15 hours on this driver, getting my CFT-90 TN42/GT driver modified, which also took over 20 hours
Response over neal to Matemineco is slow and very few information
I hope I get a light prototype with my first prototype driver boards which I will order today
ATM the prototype is set for one Attiny84 or 2 Attiny 85s, MCU and firmware is so far not clear
