I don't think the x9 is regulated like the 2*18650 lights are.
Could you expand, please?
Thommy measured his and it looks to be DD (ie, essentially hooked up directly to battery). I'm sure the build is nice, and the price on ebay is excellent, but I just prefer to be regulated at that price point even if it means going to two cells (somewhat less safe).
I agree, especially with my TrustFire F15 betraying me with 3.5-3.9A (rather than the initially shipped 2.6-2.7A samples).
But all that Thommy reported was 3.1A (from memory, but never mind). Is that enough to conclude that it's DD? Are the 2.8A Nanjg drivers as high as budget regulation goes?
I'm asking because i don't want to take part in another DD-current lottery.
I remember he said it drew significantly less as battery went down. There's supposedly a good driver(s) in the ~50$ 2 cell lights, but afaict, but pretty much none of the 1 cell ones except the x8, but I suspect that's also just a buck driver..
I see, agenthex... thanks.
Wait agenthex! One more question.
If a driver is found to be DD on High, does it mean it's not regulated in the lower modes as well? Or can Mid and Low still be regulated? My F15 is unregulated (current receding with voltage) in both High and Low.
I suppose it can be, but the med/low modes on all these lights are all just done via pwm because it's cheap (and by cheap I mean it's a few dimes worth simple circuit they copy from someone else). I'm guessing they half-ass it because most buyers don't know anyway.
No problem, remove first the double o-rings and then the attachement, back the o-rings in place and everithing fits tight without a gap.
The lanyard shown in my pictures is not the original, it's a Ultrafire that I bought a few weeks ago.
Agenthex, you really want a lot for your money. 
*joking*
Anyway it is just usd36 shipped for the "bare" flashlight from Ebay. If you manage to bid succesfully, I guess low 30s is doable, that is if the seller does not play tricks.
The odd thing about these lights is that they don't really sell enough to take full advantage of economy of scale. I mean, if walmart made a 50k unit order, they'd set up a real factory and make them for $20. Then Walmart would sell for 60.
Thank you guys for your replies.
Now all I'd need is Thommy taking tail current readings in each mode with a fully charged battery, and again at a lower voltage.
Cheers!
You wil get them by tomorrow evening
On the other hand, there are really fatal decisions made on looks alone... 
The fellow who won this bidding for $19.99 plus $13.49 shipping two hours ago, come forward!
usd33.50. Well done!
Awesome.
That's what competition brings.
That was me 
I think.
Congratulations, how2!
Thanks saved about $21, with that I can but another flashlight.
Only 2 seller were seller at this price.
You can get it for $38
