It doesn’t have any pics of one and its not in the description, I’d guess maybe not but it might.
You could ask the rep but the deal will probably be finished before you get a reply.
Thanks ezarc!
Package Includes
1 x CREE Q5 5W 500LM 3 Modes Focusing Flashlight Torch Black
1 x Protective Bag
1 x Extension Ring
What’s the extension ring for?
extension ring is for using an 18650 battery.
I suspect that’s the case, but the pics ezarc posted does not show it, which does not necessarily mean the ‘extension’ is not included.
Looking at ezarcs pic above it does show the extension installed. You can see TWO fluted connections.
At the Tmart website it shows the light with and without the extension. Without the extension there is only one fluted connector (the tailcap alone). With the18650 extension installed you see 2 fluted connectors as above in ez’s pic in his original post.
The pic shows the body with the tailcap screwed in, the AAA carrier, and the disassembled head assembly — bezel and the innards. There is no 18650 tubing /pipe that goes inside the body. The 18650 tubing/pipe is not an extension, but a spacer to prevent rattle.
Thanks for the head’s up.
Did you even look at the pics at Tmart sight? It clearly shows the torch in 2 configurations. I guess Time will tell.
The main body without extension ring is short. It will not fit an 18650 by length, only the included 3xAAAs housing.
The ring is indeed an extension, increasing flashlight length by about 20mm. It not only extend the body length, it also has built in spacer that fits 18650 exactly so it has minimum rattle.
Hope this clears things.
Looks just like the old X2000 I got back in the day from DX. It's the light that really got me started on "high-performance" lights. 
From there it was a C78 and from there a UF-501b. By that time I was hopelessly addicted.
Bleh. Mine arrived today (I thought it was my HD 2010 at first and got extremely excited, then noted the tiny size of the package).
It’s got an identical beam pattern (size/shape/artifact) as my Sipik sk68, but slightly less bright and a bit warmer tint. First impression is a bit disappointing at the $3.50 price point. Ripped it apart, hollow pill, missing 3-4 o-rings. Other than that it’s pristine; I think it needs a driver, maybe an emitter too and it would be a decent little 18650 zoomie at ~$6 total cost.
Got it yesterday and the first thing I did was checking out the “extender”. As others pointed out — and I was very skeptical — it’s the “adapter” for 18650. (The aaa cage is a little shorter than other cages, which does not need ‘extender’ to fit 18650.) (Require button top 18650.)
It’s as bright as 200-lumen zoomie, and the included holster is rather nice. Thanks ‘ezarc’ for the find.
Got mine. The included AAA cage was crap…slightly too short…would not function.
A quick look in my parts drawer and I was back in business 
No matter, I prefer 18650 to ALKALEAKS !
You need to take off the extender - the small piece between the body and tailcap.
Damn, didn’t realize the coupon code expired. 
Hello… Like I said… The carrier supplied is defective on my sample. With my other spare carriers I have it works fine.
But, like I said, I prefer the 18650 setup VS Alkaleaks.
Sorry I totally botched. You are one of the ones correcting/educating me about the extender! My belated thanks to those who pointed out what the extender was.
I have it on good authority that the “junk” ones are only sent to
એટલાન્ટા, ગા. 
Anyways awhile back, maybe it was you ezarc, that mentioned a HD2010 from Tmart. It was a Tangsfire, with a coupon, well I ordered it and am very happy. It came today, it is Silver Ano, nice threads, XM-L T6, but it pulls 4.27 amps: stock on a Power izer 26650 at the tail. With the deal, it only cost 24.68 shipped to US. Looks like they have gone up a bit, glad I bought it.
