Nice that is a great light that price well it’s a great light anyway. Glad you got a good one.
How much do these usually go for?
Congrats bikenber73. You should be able to use one of the tubes by itself to hold just one cell. See if it works that way. In stubby mode, it's not much bigger than a C8.

Lightmalls has been selling them with the extension tube for $31.50 for a long time. That's where I got mine.
EDIT: I think they charge shipping below a certain amount.
Oh reeeeeally??? Hmmm….
For $29 it could be here tomorrow…. 8)
How are the LEDs mounted? It would be nice if you could swap to 3 noctigons or something
The tube that screws into the head is longer than an 18650, so 1 is not an option.
Leds are mounted like in a SRK and lots of other similar type lights.
-Get driver circuit out.
-Unscrew the bezel and take out lens.
-Unscrew the screw holding reflector
-Then you have access to the emitters. MCPCBs are normally 16mm (the stock ones might be quite stuck though).
That’s why God gave us hammers and chisels. 
One is an option. All you need is a 20mm spacer between the cell and switch. I’ve used that setup on mine.
Thanks, I just ordered one. Aluminum mounted T6s are weak these days, so I might swap them all for noctigons later.
What specific seller did you buy from?
Thanks
One of the tubes should be shorter. You may be thinking it is part of tube that has the "Trustfire TR-3T6" label on it. That tube piece should have a knurled section after the lable, but not before. The knurled section before the label is a separate, shorter section.
EDIT: The extension tube should have 2 knurled sections. The short tube will have one knurled section.
EDIT2: OK, looked at my light. You can't get 1S config with the stock tubes. At least, not without a spacer. Sorry for the confusion.
Has anyone tried to run this light on one cell? I'm wondering if the driver in this light can run on 1S.
The driver will allegedly work down to 0.8V. AFAIK it has been confirmed to work on a single cell but you need some kind of spacer as there is ~25mm of space, so use your longest cell!
Although, I do not understand why you would want to run this thing on 1 cell. On high mode with 2 fresh cells I see ~2.25A on the tail, with 3 ~1.75A.
It is not going to last very long with 1 cell!

Why?, because it's more compact and I rarely use my lights on high. On low with one cell is uses about 200mA. Quite efficient for the amount of light it puts out. But mainly, if it runs on one cell, that tells me it has the "good" driver. The driver is tough and have some good flexability and can easily run it on Ni_mh cells.
Again… Those of you who bought one from Amazon, what seller did you purchase from? Thanks
Doesn't the a link in the OP answer that?
No. Amazon changes the “default” seller all the time. Yesterday when I clicked on that link it was “IGet”, now it is “Yes Digi”. I have absolutely no way of knowing which actual vendor the light was purchased from.
Interesting. I did not know that.
