thank you very much for your adding links.
the final UI is without breathing strobe. the breathing strobe is a trial samples’ UI.
now we have only few this UI flashlight in XHP50 version X1s. The XHP35 HI X1s now is all the H M L (hidden fast strobe) UI solution.
And we also can provide the final UI XHP50 X1s to BLFers, only need you mention it and let us know it.
hi, it is hard to say how long a flashlight can throw.
I want submit this question to our users, let they tell us.
ra
the xhp35 hi works at 1.05A max. in high mode, the official max. current according to the datasheet issued by CREE.
I know that your business plan is to provide reliable flashlights but you could safely overdrive the CREE emitters at 200% and still be safe.
At 2A, the XHP35 would REALLY throw and still be cool enough given the mass of the X1s !
Jaxman can overdrive that driver and call it the X1mod. Since we at BLF strive to push the limits of LED technology. Not let it work at suggested specs but at what is possible without compromising on safety
At 1 amp, it’s not worth it to me personally.
I will buy it overdriven at 2+ amps. All the extra cooling features need to be worth it.
Please jaxman, offer it to us with higher amps if you are able to. 
This light is soo close to what I’ve been looking for!
Great construction for a budget light!
I dont see the XHP50.2 on AliExpress, will it be added? Any specific reason why warm white or neutral xhp50.2 isn’t an option?
Exactly my thinking. I had the light in my shopping cart until I read only 1 amp.
And at only 1300 Lumen’s, theres nothing a xpl hi can’t do. Please take advantage of the xhp35 hi and the nice big light for heat sink.
if the XHP35hi has the same output as a XPLhi in terms of lumens, still ver nice, means reliable, no heat issues AND bigger lightsource so fatter beam.
I do not want to let a LED working at a non-official condition.
sorry for that, even I really can realize a double current, I would not do it.
xhp50.2 is really easy to realize. we have LED on hand ,coolwhite. if friends need,pls tell us,we can make a 50.2 light for you.
Due to busy work,we have not prepared ready for the link of 50.2
thanks for your support on my thinking.
what I most care, is that: any one Jaxman flashlight must be a solid tool. solid is first.
and what is more, we should find the balance of power consumption and the efficiency.
a 1300lm x1 flashlight has been a good thrower.That is my frankly review on the extra-power input.

How much?
Depending on colour temperature close to $50 for the XHP35 variant and about $42 for the XHP50 variant. You can check them out in the Aliexpress store.
One has free shipping. One doesn’t. So works out the same price
Sounds like an old Chinese proverb, hehe. 
I just got the email notification that they have shipped out the jaxman X1s xhp 35 hi cool white… I can’t wait to play. Thanks jaxman.
Edit: ONE AMP…? No wonder, just went outside with the old X1 and a UT02 and there are issues, very under powered, not so impressed I guess, but do realize this is a work in progress so it will improve as you go I suspect, nice host though and superb knurling.
The light is integrated shelf now as the old X1 was a pill, has a new reflector with minimal changes overall.
The knurling on the new X1 is real nice, I am telling you REALLY nice over the old X1, and the tail end threading of the tube still will lego, great mod light.
The board is DTP and lots of thermal and screwed down.
There is no more tripod screw but easily remedied.
This new light is a bit longer or taller by about 3/4” or so.
Branding is now only on the one side instead of both sides, this is nice, very clean light and well machined, As Always…!!
Pocket and shelf is fine…
Tail switch is now a three legged switch and tail stands perfectly and a bit nicer than the old two legged one as shown in pics. Sorry about the dirt on my older X1 switch, the switch a sponge boot I won’t comment.
I will reserve my complete opinions overall as this is not meant to be a in detail review at all, just some pics and some pics I won’t post here,
But I will say I prefer the old reflector over this new one and leave it at that. But I will be contacting you with something I noticed Paul.
My personal thoughts is that I would like to see 2 versions available of the X1 for sale at Jaxman, this new one and the old X1 continued but in this integrated style and with the old style bezel but with this new knurling on it, and also continue with the original LED options and driver format but as mentioned with this newer integrated shelf style, just do away with the old pill, and use the old style bezel back with this new knurling ring as mentioned
I must say that if anything impressed me the most it would be that new knurling.
What would happen if you put the extension tube on the x1s and use two 26650? More output or would you fry the driver?
Had posted a message then thought twice and pulled it down immediately,
Box I don’t know, but suspect the driver will melt down, no big deal, will be stripping it today anyhow, really wanted to say something here to my forum members about this light and what I’m seeing but this isn’t my thread…. all I will say is give this some thought…!!
