I would look at the C8F MCPCB which Sofirn does sell separately (I got one). It appears to be the same size - no time right now to measure though. If it does align, there's your 3535 triple MCPCB for the X9!
Rough measurements from outside the lens seems to be dead-on.
driver diam: 29.0 mm, pure FET based, std FET gate resistors
pill has only 5.0 mm of clearance above the driver - tight for piggybacking
MCPCB is 1.5 mm thick
shelf is 2.0 mm thick
LED wires are 20 AWG, longer than need be to allow driver to be pulled out
driver was glued with silicone like substance (plyable) - knocked out using a solder pick tool thru the LED wire hole -- came out easy
springs appear to be IOS BeCu - high quality
the switch appears to have a piece partially broken off - doesn't appear to effect it's operation, but may replace it - don't think I broke it, not sure
that "2R2" component is used in the USB-C charging circuit, not for LED output
Well, I modded my X9 to XHP50.2's, gets ~10K lumens, but I piggybacked in a driver. Looks like the stock driver is FET based, so you could just swap the LED's to XHP50.2's, assuming/hoping it can take higher amps, stock is ~15 amps, XHP50.2's in my custom driver setup hits 30 amps at max.
I don't see any other option for LED's to get more output, and the good thing is the stock driver is already FET based. But again, you always throw the dice when bumping up amps. I'm guessing it should work ok, because 15 amps is already a big #.
Well the old model had USB charging, new model is magnetic. I got one of each but both had the charging removed because of piggybacking in a replacement driver.
yes yes……xhp 50…but neutral white.sure not cool white.and i cant found them sadly…as a tripple.but for this you need bigger reflectors …so maybe the xml version can fit… cos there are bigger reflectors than xpl version…
