Have you tried to ask the seller?
Maybe is possible with a little extra.
Manx, no I just went with information from RotoHead64 , and they will tell you please yes 3 extensions and then send you 2 so unless I hear different I will pass.

Pretty sure this’ll work. Don’t know if the driver in the lixada is compatible with 3s cells though. I go for the Trustfire from fasttech. The last one I bought had XML-2’s. The stainless bezel model is nice.
Yeah, wish I’d seen the SS bezel before I leaped. Oh well. Maybe I can make a new bezel for it…
TomTop sent the light FedEx yesterday, my first order from them, what can I expect?
Thinking of buying one and dedoming it, locate a extension tube and a AR Coated lense. Plus possible o-ringing the shit out of it. But thats all I’d be capable of. I am still so new to the scene.
If you buy it from TomTop, try to ask the seller if he can sell the 1x18650 tube extension too, so we see if they have or not.
Thank you very much 
If you will look closely at this picture you will see that the extension tube(s) will not fit the head of the light, as they are not made like the part of the tube that goes into the head.
Here is the tube in the single cell setup they are showing on their site, with one of my longest protected button tops in it. The tube is about 1 1/4 to 1 1/2 inches too long for a single cell to run.
Ok,but now I’m confused…so, it only goes with 2x18650? No way to 3x18650 with the extension tube?
Sorry to ask you again, but I’ve not understand 
This is very clear. No way with only 1x18650…but like RotorHead64 said, it can work with a spacer.
Thank you so much again David, you are very kind.
Yes it WILL work with 3 cells or 2 cells either way, just not with a single cell as they show it on the site.
It only came with the one extension tube, for 2 cell use, so you would need to see if they have the extra one for 3 cells configuration
Robo, are you sure that extension is a single piece? I ask because none of makes sense, if a single cell is that much too short in the main tube, then 2 cells will really be short in the light with that long extension tube on it. In the picture above the extension is longer than the main, so, I’m seeing a line in the extension that is on the female end, looks kind of short. That should allow the use of 2 cells, the whole extension will do 3?
I wonder if 2 18500’s will fit in the one tube?
There is a 3rd piece that allows for three cells Dale, another “short” extension piece, but I did not get the 3rd piece with this light.
Here are the 2 tubes that came with this particular light, you can see the main one is too long for a single cell, and the second “extension” piece is too short for a single cell. Together they make the right length for 2 cells though.
Ah, I see… that short piece is what I was seeing attached to a full cell extension to make the 3 cells work, that’s what they’re showing in the picture. Got it.
So you see the light now huh? 
Boo! Rotten tomatoes, crusty lettuce, eggs, old XM-L’s on you!
Triple $&&98
1st 3 sec of your review. Hilarious…
The flashlight is now “out of stock”.
Wow, this is the power of BLF
Guess it makes a pretty good host for a low price?
I got the chance to have a look at robo819’s Trustfire version of this light yesterday. I like it! The fins are in exactly the right place, there’s enough mass up top to feel it when in the hand… almost feels like it’s already got some copper in it or something! (it doesn’t)
There are some places it can be improved on to bump it up in output of course, hey it’s an inexpensive light, you didn’t think they’d do everything for you did you? Straight stock with XM-L T6 emitters it made 1387 lumens. I played with it a bit, put some XM-L2 U2 1A’s in it that I’d pulled out of X6’s to make triples, used 16mm Noctigons, de-domed the emitters, stuck another resistor on the board and added 20ga leads. Simple stuff. Now it does 2443 lumens and has a tighter beam that shows me where a tree is back of my across-the-road neighbors place…. 534 yards away.
So it’s pretty easy to make it better, a more intensive approach can make it a LOT better. 
“So it’s pretty easy to make it better, a more intensive approach can make it a LOT better”
Awaiting the final brainstorm here Dale.
I got my Lixada today. That laser etching claiming 3800 lumens really bugged me. 
I tried it on one cell, worked ok at 3.73A, two cells made 2.09A, 3 cells, Oooops! current climbed and climbed and climbed and at 4.75A it blinked and I broke contact. After that it would only do .25A. Hmmm…
Driver had a capacitor loose, but I figured I’d go ahead and play. So…
I filled the big hollow pill with copper top to bottom, 24.83mm x 21.12mm with a 17mm driver bay cut in the back end. Soldered it on the hot plate to the brass press fit ring they had the driver soldered to. I cleared ano off the flats in the head and on top for the reflector and pill to make contact with bare metal. Used an FET+1 from Richard with A6 firmware and 20 ga leads. Pulled the XM-L2 emitters and put them on filed/fitted SinkPAD 20mm stars. Filed ano off all contact points from the tube/head, tube/ext tube, ext tube/tail cap… yes I kept the short tube because I like how it feels in the hand. Made a Delrin dummy cell and am using an Efest 3000mAh dark purple cell.
When I first took it out of the box it would do 1797 lumens on 2 cells. Now? It’s pulling 10.73A on the Efest and making 3946.35 lumens in turbo. I’ll get a glass UCL lens and it should break 4000. Love it when a plan comes together!
Thanks for the head’s up Robo, liking this one quite a bit!
