I had nextorch grease but ditched it a long time ago. I use machine oil in the mean time and it seems to work well.
From what I see, it's promised to ship in 4-7 days, as many other items on DX.
And yes, that is the one that has worked best for me. Scuba light silicone grease was good too, but this oil is easier to obtain (for me) and apply.
Anyway, these are all very cheap. No problem to try and see what works for anyone. I threw away the NexTorch grease without the slightest remorse. 
Yeah, I had some silicone jelly for other stuff I used to use....found it too thick for anything twisty.
I, like others advised you about nextorch grease, now the only thing that come in my mind to make you stop crying about stupid lubes is give you a better new reason like crush your squirrel's nuts xD
yep, I would be a bad daddy >)
it is still out of stock. for months actually. ive just talked to james on the DX chat. and for people interested in the silicone oil, better ask James if it is IN STOCK before you place the order.
it is a little diffcult to get a partial refund on unshipped items (=canceled items). try to avoid asking for partial refunds, if you can avoid it.
kreisler,
When the weather clears, come around for a good home-made espresso and a few drops of that fabulous silicone oil on your flashlight threads.
weather has cleared :steve: , i am coming to Sloveniaaaahhh!!
( sorry, but i took your words as invitation. hehe )
Espresso machine turned on.
I hope you'll understand that, given the current oil shortage, only brand name flashlights qualify... 
i am looking into it, good idea ;)
Fenix is brand name : 
Looking now for some good oily stuff..
Me too. Had it for years and use it on everything. Doesn’t eat any O-rings that I know of. Easy to find. I got mine at a gunshop but prob find at hardware store.
Please recommend a flashlight grease for dummies (ie me)
BTW, I'm pretty sure the lubricants recommended above were for the flashlight, not for the dummy. Just an FYI...
Ouch! Supposed to feed squirrels nuts, not crush 'em. 
In applications where it's OK to use a petroleum-based lubricant, I really like Rem Oil :
It's ostensibly for Remington firearms, but works great in appropriate flashlight applications.
Do not use with rubber O-rings or other rubber components, as with any other dino oil.
I seem to be the only one who thinks the "stickiness" or "thickness" is actually a pro and not a con. The light scuba silicone grease I use will stay were it belongs..... on the threads. I used various lighter mineral lubes and nyogel before and hated it. They went everywhere... battery, tailcap and my clothes... they were too thin... so I actually prefer thicker lubes because it makes fiddling around with not so well cut threads so much easier. Also silicone lube is non-toxic. I use it on everything twisties, clickies, anodized, non-anodized ... no problem at all. The slightly higher resistance is a non-issue for me. Although, I noticed that my light scuba grease is not as solid as the nextorch stuff, it moves at very slow speeds when I move the jar.
thanks for sharing Vectrex!
if we all lived in the States we would probably use exclusively the Superlube stuff. 3$ for a litttle tube (1/2 oz), 5$ for a large tube (3 oz) and available from many vendors (incl free conus). the generic term for super lube is either < teflon grease > or < teflon oil >. Those lubricants are popular among cyclists (where are our cyclists@BLF when we need'em in the discussion?) and gun hobbyists, and any gun shop and bicycle shop would offer teflon-based lubes (also < teflon spray >).
Superlube seems special in many ways: The entire company is specialized on selling it (Synco Lube), the stuff is patented, and more sophisticated than the generic teflon lubes. And last but not least, it's cheaper than the competition.
Ebay asks 8-10$ for global shipping of a mini tube of 3$ Superlube (no thx!), so i am checking now a few other sensible sources..
Vectrex your stuff seems to be much better than the stiff sticky Nextorch ***p. Am just thinking that any teflon based lube must be way superior on the threads (if one wants soft and easy twisting action).
@ Vectrex: I think one of the problems can be quality. There seems to be more slop in budget lights' threads, requiring more lube, attracting more grit or leaving more lube behind.
You are likely using higher-quality torches with the thicker lube, as well as with diving lights - the thicker stuff being extra insurance against water intrusion.
I generally use the thicker stuff in joints that are less frequently used, along with those using metal/plastic threads. (e.g. Jetbeam PA40, Fenix LD40)
I like the thinner stuff (RemOil, et.al) on tailcaps, since they are more frequently removed for battery installation, and are more often wiped down (and re-lubed)
I had the silicone jelly on a Fenix L1P and a Quark at one point. The Fenix particularly didn’t like it because of its fine threads.
My silicone jelly came from a plumbing dept, so there may be thinner versions. It might work good on lights with sloppy threads.
yepyep. that's the perfect version. Item no. 21030, i.e. 3 oz. of the standard Synco product. I talked to the company and they informed me that "Super Lube" and "Superlube" are protected trade names in Germany and that's the main reason why nobody in the world is allowed to officially sell Synco's product under this name ("Super Lube") in Germany, neither thru a distributor channel, amazon or ebay unless you want to risk getting sued. There might be other reasons why most/all U.S. dealers do *not* ship the original product to Germany economically ( i am not going to pay 8 or 10$ ebay shipping costs cheapo me hehe). I found a German dealer who sells the liquid form of Synco's Super Lube, namely the Super Lube Precision Oiler (renamed to "Synco Lube Oiler"):
That dealer might be able to offer "Synco Lube Grease" in future but that might take a while. So for the mean time i've ordered the Synco Lube Oil and will test it for you, me, us. Typically watchmakers and camera fetishists use Superlube Oil .. for minimum friction in rotating fine machine parts (watches, clocks).
I am just looking for minimal drag in my twisties (Romisen zoom, Quark tactical UI, AAA keychain lights), especially on bare aluminium threads.
I will keep you posted if kreisler recommends the stuff or not. be my word the last on the topic "synco's super lube oiler". where's your trust, where's my credit? i am doing it as BFL service ;)
Kreisler:
If you have any stores (ConUS would be Cabella's, Bass Pro Shops, Gander Mountain, etc.) locally that cater to fishermen, you might try fishing reel grease or fishing reel oil. Ardent is one brand I've thought of trying, but I'm testing out bicycle chain oil right now.
