Well re: driver… could be, I’m at Alie and answering a message to owner now, I mentioned a solution but he is the final word.
The light improved and worked with two cells and extension as it should with a single cell out of the box, I am a long ways from figuring out what is actually wrong with it besides just under powered, I question the boost in this driver, what is it boosting.?
I have to rebuild mine without a doubt, I have the very first version of this new X1 and it has some issues but nothing that can’t be easily solved.
The three legged switch is great and it also has one leg that he planned as a two hole and then the other two legs are each one oblong hole, but comparing it to the old version 2 leg tail cap this new one tail stands like a champ really nice.
I’ve been loking at the driver and I think it’s a modified H2-C, looks like the sense resistors are not the stock ones. (R050 instead of R100). My question is, Do you know how many Amps are driven to the LED?
I think he has it at 1 amp which should be to low, but do recall him mentioning worries about safety and a normal user, not sure if I followed him correctly, but interesting that you mention that particular driver because I thought the same thing but was no way sure of this, but had been following this thread, Buck and Boost Drivers, Testing, Modding, and Discussion (Pic Heavy) and it was sure ringing a bell with this light in particular, there’s some good info on that thread re: the KD drivers and resistor mods and so I’m with you on your thoughts here.
That does look like the H2-C driver. The H2-C comes with 2 R100s stacked, so equivalent to one R050. Stock it outputs 1.4A.
Thanks Easy, going back over to that thread I linked up one here, I see now, I didn’t know what two stacked R100’s equal out to, but now I see it in the list 4 pic block down or so, Thanks, explains also why the designer of this light said it’s at 1A, after step down from 150% I guess, sure haven’t noticed any step down so must be very subtle, Thanks again, gets me a bit closer to figuring out what I’m trying to figure out… haha
I cant plug one word even…………
Sure you can Paul, what word you need to “Plug”…?
You know we all love you Mr Paul Jaxman… ha ha ha

I need to come get a new X1S and a old version X1 also, plus X1S with XHP50.2 with smooth reflector, I think, maybe tomorrow,
hope you can like it!
So I know this jaxman X1s use 26mm x 65 mm 26650… can I use liitokola 26.5mm x 65.5 mm ??? Thanks.
Yes, shouldn’t have any problem, just to be sure I just put in a EVVA 4000mAh protected and works fine, I know Jax says protected don’t fit or work but they do.
Edit: Sorry I know there’s a difference between EVVA and the Liitokola so put one of those in as well and fits great.
hi,see this: 
Very good info… thanks jaxman.
Jaxman, have you guys tried putting the xhp50.2 in the smo thrower reflector?
It should be a decent thrower with high output.
SEE THE 245m throw 
Is that version available for purchase?
@blueb8llz,
hi, who says xhp50.2 is more powerful on flux than xhp50？
A mis-understanding. As I know,the xhp50.2 is not powerful at flux than xhp50. It has not a cross in core,xhp50 has.only this is their diffence.
The XHP50 on my hand is K2 glass. but I can not get K2 xhp50.2. All xhp50.2 in my hand are J4 class.

We surely can make a customer ordered for you.
no problem. smooth reflector+xhp50.2
