The X9 came out when the D4S and E07 were also being released and doesn’t get much attention but it is a very nice light. Not as many whistle and bells but powerful and it’s simplicity is ok for me. No homework to operate the UI.
Yea, this form factor is goin nuts as of late. I still don't have a D4S which I'd really like, but there's so many similar lights now. My X9 will probably get one of those more complicated UI's though... The ramping in the X9 is pretty decent though, but still I'd like to see them standardize on the 1 click ON, 1 click OFF, hold to ramp or change modes. More lights are implementing this, and not our firmware. It's not a BLF original thing either, not sure who the early adopters were.
One click on, one click off would be welcome . If it was the only UI I used, the X9 would become second nature but the way it is, it makes me think about it. Can it be flashed or does it have to be changed ?
No, just checked. You would think the tailcaps at least would exchange because they look exactly the same, I mean exact same style and logo image. Inside, totally different - The AX2 has a Emisar style spring and PCB while the AX3 has the copper looking wire thing.
At the head, the AX3 tube flairs out while the AX2 doesn't - not even close to the same size. The tailcaps I couldn't get to thread either, though they look close.
Does anyone have a photo of the back of the reflector and the MCPCB?
Trying to figure it the feasibility of using non 5050 LED’s and trying to see if there’s clearance for individual Mcpcb’s wires to clear the reflector cups if I go that route.
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 #.
