I put the Banggood link to it in my post above, nothing about zoomable in their listing, they have a photo of the head unscrewed from the tube, looking at that photo pretty much verifies itās not zoomable.
But what did you think about that MS600?
The Manta Ray C8.2 looks to be at the top of my new list, it just looks like it has a tad too much material on the light for me to decide on it now.
I am still keeping my eye out for āthat lightā.
Too bad nobody like Kaidomain sells F13 with a XHP50.2 in it. I would buy a couple. But that looks to be a mod for me in the future.
But the Jaxman Z1 will be my next light with the short tube. I like the even wall of light from the zoomies and the Xhp50.2 should put that wall out there.
The 26650 Edc I am wanting needs to be simple, waterproof, no moving/zooming parts. It will have to be the F13 with a Xhp50.2. That is a great looking light.
Iām not a fan of the twisty and smack features.
F13 at Fasttech around $13 after BLF code:

UltraFire MT-12 (Looks same as F13) at Fasttech (.57 cents more than F13)

Order two more 
Thanks!
Yeah I ordered one back on the 3rd on that deal, I was surprised to see it was still valid when saw your post tonight and tried it. But sometimes that happens (very rarely) but figured I check.
I just picked up 2 F13ās too. Now to see if the S2+ Code will work.
Why do you think one of the FastTech F13s is a clone? They are both labeled āauthentic.ā From what I can see, the difference is that (the cheaper) one comes with both an 18650 sleeve and a 3xAAA carrier.
Hmmm, yes I guess ācloneā was the wrong term, what I meant by that was itās a different model but appears the same as F13, couldnāt think of a word for āsame item but different model numberā 
I reworded it to avoid confusion, thanks for pointing out my mistake. :person_facepalming:
Do you have any idea why itās a different model #? I honestly never saw or heard of the MT-12.
Hereās an interesting tail switch light, possible host. Only $10.56 after GB17LED code.
About the same size as an F13, and a smidge smaller than the Manta Ray C8.2.

No telling how itās constructed internally, but it looks pretty nice. Would have to take a chance on the budget light lottery.
I received my Trustfire A8 from Kadiomain yesterday. Itās a very nice light all around. Itās quite bright too. It has a good combination of flood and throw. The transition from the āhotspotā is very smooth, which is ideal. The color is a metallic grey. I have a Keeppower 26650 from Amazon in it. I wish it had options for other group modes, like a 100, 50, 25%, moonlight would be nice. Or if it just didnāt have the blinkies I would be happy. The color seems to be around 5000k, not the Cool white like most of my lights. I really like the color of the A8.
Overall a sweet light.
I also got my 2 Ultrafire F13ās which are good for a great price, no modding yet.
I ordered a Convoy BD06 from Simon and that should be here in a few weeks.
I couldnāt resist and ordered a Convoy M2 from Simon also. Then a C8.2 Xhp50.2 from Kaidomain.
But the Convoy S2+ Sand from Simon finds its way in my pocket most. Lightweight, bright, and great mode selections. I will be picking up a second S2+ sand, since my wife stole mine. :+1:
Thanks for all the suggestions fellas.
I just got the manta ray host version and overall quality is a lot better than the UF f13 (having owned several f13s in the past). The host is about $20 which more expensive than a f13 w/discounts. However, the f13 has a lot of space in the driver area so itās easy to add reinforcement to the shelf for better heat sinking or to fit a boost driver to run a xhp50.2 w/ a single cell.
Unno, I still like the F13. Gawd, those threads are buttery smooth right out of the box. I usually have to scrub and relube all the threads from every light I get, but the F13 required zero.
Received my F13 yesterday. Itās huge! Larger than I expected.
I dunno, canāt really say Iām a fan atm. Not sure what Iām gonna do with it, it was an impulse buy, shelved for future modding.
.
The threads on mine are poorly matched, considerably loose at both the tail and headā¦
And some sharp / jagged spots thatāll need smoothed down, but itās about what I expected.
Donāt really like the feel of it in hand, the short tube with my thumb and forefinger resting on those massive sharpish fins.
Although the fins do provide some serious anti-slip grip! Mine has that awesome āXML-T6ā etched on it too. :person_facepalming:
Otherwise it does appear to be a solid host. Built like a tank. Donāt get me wrong I donāt hate it, Iām just not super thrilled by it.
Maybe itāll grow on me. It was a good value for ten bux though. Iām gonna have to put something awesome in it to make me love it. :smiling_imp:
.
Actually Iām totally spoiled by the Eagle Eye X7 that I bought for a host.
Feels way better in hand, more compact size, square threads, beautiful matte finish anno.
Comparing these side by side really puts it in perspective, twice the cost for twice the light.
To itās credit the F13 does have a wider reflector in the same head diameter, so Iām thinking it should have better throw.
My Ultrafire HD2010 (bought in 2012) has the most buttery smoothest threads EVER!
I think the older F13ās we manufactured to a better quality. I purchased 3 last year and the overall quality wasnāt the greatest and the threads were not buttery smooth. But became smooth after some grease and repeated screwing on/off parts.
Actually, the hands-down absolutest bestest smoothest threads Iāve ever seen are on my lowly ā502B. Big beefy triangular threads, no less.
Screws on like an end-cap on a pipe, glassy smooth (and I mean glassy smooth), no hint of binding, not even much jiggle as if too loose. Screws in all the way and then nicely snugs up when it hits the end.
No idea what they did, but they done real good.
Unanodised, so maybe that makes a bit off difference. Itās that nice semi-gloss black, still grippy but without being chalky.
Hey, thereās a reason why itās still my EDC even with all the other lights I got.
Whereād you buy your 502b? Sounds like a good one. Thereās hundreds of 502ās out there, probably from a slew of different factories.
I was looking at this one (host): https://www.fasttech.com/products/0/10002463/1409307-ultrafire-wf-502b-led-flashlight-host
These were a few years ago from my Amazon days (ā501s/ā502s/C8s/ā98s).
I went on at length about the race-to-the-bottom death-spiral of quality. All my ā502s I bought when they were still good, using either real Crees or at least good LB clones. Cheap drivers (resistors, no regulation), but decent emitters, albeit on the cool side, āthough not Angry Blue. Even the switches were really good, no flicker or anything on my daily-driver.
Alas, it was the same for C8s, too, when I started getting āem. Good quality.
Later, about in a 1-2yr span, quality went down the toilet. Never got more ā502s as I was hip-deep in āem, but as far as C8s, thatās when they started getting cheaper and cheaper. Crappy featherweight Al pills, plastic reflectors, cheap switches, E-sized emitters that may have been clones of LB clones, would barely put out 3-digit lumens, more like 70-80, āthough concentrated into a pencil-beam. Really bad. Hell, even to use as a host, the body would be lightweight, obviously thinner and lighter than earlier.
Anyway, my first C8s were great, later ones crap. I complained to Amazon and/or the seller (forgot which), and got a partial refund for the crap ones.
So nowadays, I wouldnāt risk getting any generic light from Amazon, period.
Youād probably have a much better chance getting something decent from FT, especially if listed as āgenuine Ultrafireā(!).
