Ultrafire F13 mod

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.

D10ten, thank you.
I’ll try with xhp35

What is the diameter of a star in U13?

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.

Today finally got my F13.
The switch is damaged. :frowning:

I’ll try to repeat the mod using XHP35.

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.

7.50 for 10, free shipping. :smiley:

The washers are also available on ebay for cheaper if you don’t mind waiting for shipping.

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.

22mm is an even size, 21-23mm is odd! :wink:

Aaauugh, yer killin’ me here…

It worked!

Ouch, that’s >6bux for the 2 washers I’d need. :smiley:

I used copper washers for my F13 and F15 mods and it worked like a charm (both fitted with 17mm LD-25 drivers)

ETA: Actually I used copper washers soldered to these adapters

http://intl-outdoor.com/17mm-to-20mm-brass-ring-driver-adapter-2pcs-p-804.html

The washers were 22mm outer diameter, 16mm inner diameter, 1mm thick

Hmm, the first one I can’t tell from the pix if the driver would drop straight through, or if there’s a ledge for it to sit on.

I want something mechanically sturdy, not just solder sticking to glued-on Cu foil. Pressure from a 26650 and big honkin’ spring would push that right through.

A 16mm hole for a 17mm driver leaves at least a ½mm ledge for it to sit on.

The second washers are a little thinner, so the driver would probably just sit right on it. Not much thickness to drill a ledge into it. Not a bad price, though.

A 17mm driver sits perfectly in there. No way it will be pushed through

All I can say is that I’ve run that setup in a bike light with all the rattles and bumps and it’s still going strong after over a year. YMMV

Ah, so it probably does have some sort of ledge for the driver to sit on.

There ya go…

F13 Questions BLF,

The F13 switch stinks. Will a McClicky switch fit. Will the McClicky 11/16 screw directly into the F13 switch threads?
