Doing stuff like that will keep you young forever!! Trust me, I know!! 
Foy, I have searched the thread to see if there are any pictures/specs of this light connected with just ONE 18650. Could not find any! Have you ever run this in single cell mode, and if so, are there any pictures of it out there?
Thanks,
ceh (a 72 year old kid)
Thanks for doing the L2/M8 comparison, Foy, much appreciated!
tail cap draw: 2 x unprotected Panasonic 18650/2350
low - .05 amps
medium - .61
high - 1.12
1 x Panasonic 18650/2350
low - .10 amps
medium - 1.23
high - 2.43
Thanks how2. I thought I included pics of it in single configuration . . . will do so soon.

Ok, who’s got this one AND claim they can fit 2x 18650 protecteds in???
Just got one today, first impression is good.
Had only 5 minutes to fiddle before work, second impression is bad…
I cannot fit 2 betteries in even by a large margin. It will not reach to threads.
In short mode: it reaches 1.5 turns, O-ring is visible and no power up.
I believe the tailcap brass slug is jammed. Even with it working I doubt it will fit 2 protecteds.
I have mentioned a couple times about it. Remove the brass cap and is OK with any cells.The brass cap is OK for unprotected cells, mine came with 2 thin magnets. You can use one between two Sanyo UR18650F/M.
If non-anodized parts cannot touch non-anodized parts it wilt not power up, because anodizing doesn't conduct current.
I can fit two AW 2900 with the brass cap on and the flashlight works, but it's very tight.
OK, I will try it later today.
Using now 2 TF3000 to test.
Did the thing now.
Tried with 2x TF "flame" 2400´s UN-protecteds and worked fine.
My shortest protecteds are TF 3000 "flames". If I squeeze and squeeze beyond all comfort, it will work but just barely....
Absolutely NO HOPE of getting this to run on my better batteries, the Xtar 2600´s.
I mean, what the hehehe is the idea to make a near-perfect flashlight and then throw a dice when deciding the length of the battery tube?!
Well, I guess nothings perfect, so it had to have that one miss-tied knot...
Cheap Thrills:
Did you remove the brass cover off the tail cap like Hikelite suggested? You should have no problems if you do:
Oh bugger, did Hikelite mean the WHOLE thing on the left to be removed?
I took out just the spring cover.... :|
Going to try again ->
Hmm, obviously not, just the slug above the spring.
(if I take the whole thing out, PCB is naturally loose, battery cannot fit inside that aluminum threading)
Too bad really, I would feel more comfortable with 2 battery light when using Protecteds.
My bad for not addressing this. I guess I take too much for granted. Like Hike says, if you take the plunger out, two average, protected 18650s will fit . . .
. . . remove switch "pill" from cap (left) then remove brass ring and plunger/sleeve assembly (right) . . .
. . . lift brass ring off plunger/nylon sleeve and screw back into switch pill leaving spring naked for all the world to see . . .
. . . re-install switch pill into cap.
Protected Solarforce (left) and unprotected Solarforce. (right)
Is flashlight a little short for two protected batteries? Yes, but if spring cap/plunger is removed, they will fit and the light functions perfectly. Foy prefers unprotected cells and so avoids the whole mess . . .

Big thanks again Foy.
I think the thing I now need to do, is to deliver this light to my pal with two UN-protected ones with some safety-talk first.
After that, I think I saw somewhere a thread (HKJ´s maybe?) with some physical measurements of batteries.
I´m quite sure I can find at leas a bit shorter ones than TF 3000´s.
It is a matter of one millimeter tops to get it going properly!
According to Old´s measurements, Solarforce 18650´s should be about 67.7mm
compared to TF 3000´s 68.8mm each.

Should be a piece of cake getting a good fit with those :)
If any other recommendations for short 18650, keep them coming ;)
Thank you kindly sir!!
update:
My XinTD is pretty much a full time shelf queen. I can report that it turns on reliably once every three months, without fail.
I need to comment however, about some tail cap issues. First off; as impressed as I used to be with tail cap spring caps, in practice they have been a pain in the butt on several of my lights. On this torch, the light was not coming on with certain batteries. Took the spring cap off and now it no longer cares what battery I use. It also pulls about .20 more current. My theory is that the cap keeps the spring compressed, actually pre-loads it, reducing pressure on the battery.
Next problem; if I screw the tail cap locking ring down too far, the boot pops out. This happens often because it loosens a little each time after tightening, requiring re-tightening . . . and if it's too tight . . .
The X-Power Wildfire solves this by threading the locking ring counter-clockwise, something all manufacturers should do, as far as I'm concerned.
Not a big deal but, Foy's job is keeping the record accurate. I still worship this torch and no, I don't care if you think I'm a whack-job.

3-8-13 update
Been about nine months since my last update and I'm still in love with the XinTD. If you like looking at your flashlight collection, you'll love having something this beautiful to see.
Also, it's a pretty dang awesome torch.

Thanks again for the update Foy.
I just went to look for one at intl-outdoor and they’re no longer listed.
Looks like you may have a limited edition.
After seeing this light I just had to register to ask, is it possible to buy this anywhere? I Googled for ten minutes and could find this model anywhere. IO is out. Or is there perhaps a similar light? I was going to buy the CNQG HB-60 host, but it looks lame after seeing this XinTD L2.
Thanks for any suggestions. Also, thanks for the great forums, I've already learned enough to build my own flashlight just by lurking. :)
I want it badly!!! Who is gonna part with it for some $$?
