Ultrafire F13 mod

The F13 is a nice light, takes a 26650, is nice and beefy, could run some decent power and still stay relatively cool. The UI, though, was rather annoying. H/M/L plus blinkies… yecch. Dis-co-nnect!

So, rather than suffering in silence, I figure I’d share my modding misery. Big Smile

Anyway, I was doing this already, didn’t want to stop (inertia, and all that), so just grabbed some Truly Crappy cellphone pix while I was already in-progress.

 

Start with a standard F13 ( http://www.gearbest.com/led-flashlights/pp_5499.html ). The driver was a µC with parallelled surface-mount chip-resistors to provide the ballast. So expect the current to be hideously unregulated from a fully-charged cell to almost depleted.

I chose this driver

https://www.aliexpress.com/item/5-Mode-1Mode-Input-3V-15V-dc-22mm-LED-Driver-For-Cree-10W-T6-XML-T6/32746300708.html

instead. I don’t intend to run it from multiple cells, but it’s a somewhat hard-to-find 22mm driver. I’ve got plenty of 17mm and 20mm drivers, but never needed a 22mm driver. Now, I did. I got the 1-mode (on/off) to not have blinkies, and because the F13 should handle that power pretty well for an extended time.

These are they, nicely delivered as a single “stick”, 2-wide, for the total of 5 drivers I got. I snapped off the oddball one and filed down the periphery to let it fit easily into the head.

 

Well, first off, I had very limited headroom inside the head, what with a big honkin’ toroid taking up lots of space, plus the wires being looped through and coming out the hole. So I had to snake the wires out of the hole to come off the board directly. That got me this

plus, you can see the old driver on the table, with those 8 parallelled resistors on-board. Oh yeah, I had to desolder the spring from the original driver and solder it to this bugger.

Also, I didn’t want the wires wrapped around the toroid to be pressed up against the shelf that the LED sits on, so I took a PTFE disc insulator ( https://www.fasttech.com/p/1138102 ) and placed it inside the head on the opposite side of the shelf, thus:

 

Next came the emitter. Had my choice of a U2-4C ( https://www.fasttech.com/p/1574600 ), or a T6-3B ( https://www.fasttech.com/p/1425002 ). Chose the latter, a little whiter but a lower brightness bin, vs slightly warmer but brighter. Maybe my next one will be the 4C…

Didn’t mangle anything, thankfully. Damned wires had a life and will of their own, and didn’t want to be soldered to the star, the way they wriggled out almost every time I attempted it.

(Hey, I did say these were crappy pix…)

Anyway, I can’t find my microscopic tube of Arctic Silver 5, so for now it’s the reflector pressing the nekkid star to bare metal in the head. When I find it, I’ll grease it up. Don’t want to use thermal epoxy, or just glop on some Fujik, so I’ll wait ‘til the AS5 turns up.

 

Anyway, here’s the finished product, which looks from the outside exactly the same as it did before I started. Big Smile

And yes, it says XM-L2! No more of the omnipresent “XML-T6” [sic] like on cheap craptastic lights.

So, that’s pretty much it. Had some problems with the switch, the insulating spacer coming out from the retaining ring and keeping the switch-board from making contact, but I ironed that out. Lights up nice and bright, does seem like it could be almost in the 4-figures lumen-range, but haven’t taken any tailcap-current measurements or anything yet.

I’m not too thrilled with the beam, as the hotspot is a little fuzzy, and it’s a little ringy. Wondering if I should shave down the included spacer / centering-ring in the reflector to let the LED sit a hair deeper in the reflector. Any beam-gurus, feel free to chime in with advice!

Hey mate cool mod!

You can find heaps of XHP50/70 drivers in that size.

Ringy beam could possibly be fixed by shaving the gasket down

Hjeh, tnx. It was more to get rid of the lousy UI and resistors, and get what should be more or less constant current. I figured if no one ever used one of those drivers, it’d be helpful to post the “mod”.

I’m kind of afraid to try it with 2 18350s, because I don’t want anything to pop and have to go through this alllllll over again. Big Smile

Damn, didn’t measure the tailcap current last night. Was meaning to, but got sidetracked.

But alas, it’s more like 700lm from a single cell. Lit up the room nicely via ceiling-bounce, but when comparing it to my VG10 on high, it wasn’t as bright. Was more like my ~700lm ’502, in about the same 5000K-5500K CT.

Still, I’ll take it. More runtime, less worrying about overheating, etc. Wasn’t even getting the F13’s head warm, let alone hot, so a) I need to grease it up with AS5 to make me feel better, b) my 26650 might need charging (been using that in my DV-S9 for quite a while), and/or c) the F13 soaks up and dissipates heat very nicely.

I bought a single cell boost driver from kaidomain in that size it would go awesome with a xhp50 and 26650.

If you ever want to upgrade in the future.

I will do you one better Silly They have more options for 22mm drivers.
http://www.kaidomain.com/p/S025264.FX35-22mm-3V-4_5V-2_5A-5-Mode-Boost-D...

Oldlumens done heaps of mods with these lights he liked them.

I will have to buy some my self and play with them they are a fairly cheap host.

The driver i bought was a different colour. Fasttech just got some in the other day also i was looking at there email i am not sure about the sizes.

If your happy with the lights leave them but maybe in the future you will want a pocket rocket.

Ugh, same insufferable blinky modes…

I just looked again at FT, either I completely missed them (doubtful) or they just got in an assload of new 22mm drivers. All for XHP50s/-70s, and all seem to need 2 cells.

Maybe I could use the pair of 18350s I got (wasteful to use an 18mm cell when you can pack in a nice fat 26mm cell), but I hate putting cells in series, and I don’t want to get 26350s or whatever, just for this. <grumble>

Well, it had better be a big pocket for a ’13, at least. Big Smile

I saw in the spacer thread that someone was really happy with the spacer to make a F13 into a triple.

Eh, I’m not into floody lights (yet). I like the pretty tight beam of the ’13. Almost as tight as a C8…

Yea the drivers from fasttech are for dual cells i was thinking about buying some F13s and put the 4amp driver in and use a shaved down XHP50. Just for a laugh i am all against using none versatile flashlight but then again i always run my C8 with a XPG3 that does 8amps. Using the 26350 the run time should be decent even 30mins at 2500+ lumens is good. I think the throw would be decent?

Richard has a 22mm driver, and you can choose firmware, driver current and spring/no spring:

At that point, there’d be lots of overlap with my L2. And that I can run with 1 or 2 26650s. With lots more runtime. Big Smile

I’m confused already as to which of my “active” lights I should take to go see what’s making noise in the backyard, or looking for the armadillo, seeing if the cat ate his food, etc., that it’s already a long drawn out decision. Adding another light to the mix would only confuse me more.

Yep, saw that a while back, before ordering these donks from AX.

Problem is, the way those 7135s are situated, they might probably would clear the thin ledge on the LED side, but no way would the retaining ring go over those on the spring/battery side.

Same situation with the NANJG 105C vs 105D and the retaining rings on S2+es. The C (with stars) will fit, but the D (no stars) won’t.

Just recalled, I was debating getting it anyway and just desoldering the 7135s on the spring side. Only 3A instead of 6A, but it would fit the ring.

You were looking for a driver, and now, apparently, you are well guided in the proposals.
What driver (XHP50.2) can you advise for my “project”?

Haven’t used any boost drivers except for Mag mods, so don’t have any advice on that.

The one above looks interesting, though. Would rather no blinkies, but…

I also want to try – the host is already going.

What is the diameter of a star?
And can I try XHP50.2 with this driver?

This is a 22mm driver and will only work for 12V LED. The good thing is the strobe is hidden and I have not activated by accident yet.

Okay, I happened across some copper washers, decided to get a bunch of M16×22×1.5 washers. 16mm inner diameter, 22mm outer diameter, 1.5mm thick.

Should drop-in nicely into the F13’s hole, and 16mm vs a 17mm driver leaves a ½mm ledge for the driver to sit on, and I can either let it sit on top of the washer, or with a step-bit half-drill a 17mm “pocket” for the driver to rest in. Either way, solder the critter into the washer, and it’ll be an instant 22mm driver.

Just ordered them, haven’t arrived, but will let youse know how it goes.

Also, those washers are big enough to drill a 19mm hole and have a 20mm ledge, to be able to use 20mm drivers in the 22mm F13.

I had been thinking about a driver for a 22mm cavity, and wasn’t finding many super-exciting options in that size. I hadn’t considered a copper washer, thanks for the idea. Where did you source them? I’m seeing a 10-pack on McMaster for $12.57 + shipping.

One of mine was iffy, too. Someone suggested just loosening the retaining ring, play with the switch to make sure it seats well, and then gently snug up the ring again. Sometimes it just binds, and that jiggling “fixes” it, and for me, it did.

In the meanwhile, I got a bunch of these (1-mode) and posted the “mod” in a different thread.

Also looked at the 22mm driver from MTN, with 16 7135s. Looks nice, but I doubt the retaining ring would fit over the 8 on the spring side, so I’d have to custom-order one with only 8 on the component side.

Would be nice to be able to use plain ol’ common-as-dirt 17mm and 20mm drivers in this donk. 22mm seems like an odd size.
