These are the cheapest 3 mode ones out there, at least I havent found cheaper ones.
I ordered couple of these, still waiting for them to arrive, I hope they are good as the ones from vikicompany.
What is the point of it, besides size?
Was ir 2x-3x the runtime or 2x-3x the brightness, I dont remember?
Well with 2xAA I got about 3.5 hours runtime, compared to 1h or so with 1xAA, same brightness.
With 3xAA (3.6V) just more brightness + you get a nice club out of it.
Thanks for clearing that up for me, I have the last link you posted, Police ligh 1xAA, I have tried it on my SK68, but only tried, never tested runtimes and it sits in the drawer, waiting for its day to come 
I should buy 2xAA extension light then, if youre saying that it adds brightness, should work like a charm on 3 mode SK68 out in the country side 
BTW, first link you posted, doesnt look like its head can be unscrewed or am I wrong here?
Cant tell for sure by the pictures.
In the shot of the extended SK68 I don’t see where any of the lights he shows here gives the scalloped profile for the inch or so right after the battery cap. The Police 3W must be a different design too than the one I have from DX which looks identical because mine sure doesn’t have a screw-in head so it would be useless. I can see where Link 1 (& plausibly Link 2) matches the last extension but that’s about it.
You can just buy a cheap 2AA light from ebay and use it as extender for Sk68. LINK 1 LINK 2 LINK 3

Do you have parts from 2 links above in that picture or how is it assembled?
Nice, anyway…
I used also this seller:

IMO these were 3 Sipiks of best quality I have yet received.
(up to date, have ordered maybe 15-20?)
Threads were better than they usually are, lens was clean, clicky was not stiff.
Zoom was very firm and did not wobble at all. Tints were on par each other.
Weird. I expected worse considering the price…
I only have this saved on my computer. But there were some complaints on that huge Sipik clone thread that the design of this cheap “extender-Police-bright 2xAA” flashlights probably changes with each batch.
I can snap some more photos for 3xAA config, if anyone is interested.
Searching ebay for “3W flashlight” yields this: LINK ,this LINK 2 and this LINK 3
Yeah, 3xAA NiMH is basically same as one 14500, voltage wise.
See this BLF thread for my pictures of AAx3, AAx2, AAx1 ebay extensions: https://budgetlightforum.com/t/-/7619#comment-150614
The "scalloped" is the $2.80 "Police" torch, and the "C3 clone" is the better $3.80 (2nd and 4th light in the picture). Both can be used as 2x or 3x. The C3-clone has the same knurling pattern as the SK68, looks perfect as AAx3 or AAx2, as if it was custom made for the sk68 itself.
UltraFire 3-mode VS UltraOK 3-mode:
ebay's DayXmas/Eletrading/Eleconnect etc used to ship from AmazPlus.com, are they still around? I got 2 of their UltraFire 3-modes. Bad knurling, bad machining, bad paint, but EXCELLENT 3-MODE DRIVER.
VS UltraOK 3-mode (I got 2 with Silver Ring) has the Best knurling and machining of the bunch, but HORRIBLE DRIVER WITH BAD MEMORY!!! Out of my 10 or so XR-Es, these 2 ultraOKs are the only ones with EZ900 smaller-die emitter, but its HORRIBLY BAD MEMORY erases all its other merits. There's nothing worse than an unexpected WTF reaction when you reach for the torch and get hit with Seizure Mode.
My Choice? UltraFire 3-mode, despite the bad machining, it has No-memory, so it always starts on High, no guessing around. Add the long runtime from a perfectly matched C3 clone AAx2 or AAx3 extension, all for under $10, makes for excellent gifts.
tl;dr summary: Get the UltraFire 3-mode(ebay DayXmas/eletrading/etc) with the C3-clone extensions(link,now $3.09): perfect fit, same pattern, and longer runtime. Do not get the citipower G7(weak, no extension).

Ordered one 2 x AA “police” light to see will it mate.
dont waste ya money on these sipik clones .
Your reasoning being?
a number of reasons…it just doesnt seem to work for me. iv tried to edc it in front pocket and in pants …it gives an unhealthy cheap vibe that i cant really explain!!! does not feel good in the hands i supose.
Its like a women you wana sleep with only once!
bulky little ,unreliable light that i would never trust to take out camping or use at work. the switch is worse then the doller store lights. i bought 6 of the various clone ultraok/no name and others .gave most of them away. i kept one that i plan to mod
Mine are all but one ok, except for not being water proof up to IP-X8 standarts they are working like charm, I EDC one, it has sturdy clip, I have dropped it numerous times, single mode, works like new and has never let me down.
Now, the one that isnt working perfectly seems to be little bit picky regarding battery voltage - it will work fine until at some point it will refuse to light on when switch gets pressed, it never happened with fully charged battery tho, only with already used NiMh’s.
yah .most users seem to love these sipiks .i completly agree that it does provide good lighting. my flashlight family consists of various models of fenix/streamlights/maglights and eagletacs,jetbeams .
.maybe thats the reason i dislike the sipiks
Most likely, I too would hate to realise that 6$ AA light throws further than 30-50$ AA/2AA ones, runs on high* as long and is rather shock proof 
*outputs in lumens may vary, but Im talking pure throw here
……
Gifted an UltraOK one to an old workmate.Next time I met him,he told me
that his wife took it.Also that he only had five dollar lights before.How do I tell him the shocking six dollar truth?
