Ultrafire F13 at $11.39 - with Coupon Code - Gearbest

I have to say I am impressed with the customer service at Gearbest. They sent the wrong model (XML-T6) I contacted customer services to tell them, they said keep it and we will send the correct one out and today it arrived with the correct XML2, not sure what bin definitely cool white but much nicer than the blue white of the XML and as a bonus a bit brighter.

Very good service that I would say and I will use them again after this :slight_smile:

Just ordered 2 more… surprisingly the code is still working… now just hope they send me the XM-L2 version :stuck_out_tongue:

Code still works, just ordered two more. Going to mod the first two so now I’ll be able to compare to a stock version.

Credit where credit is due… I ordered 2 of these; got one xm-l, the other xm-l2. Started a ticket with GB, upped photos, they volunteered to send a replacement, and I got it reasonably quickly. Relatively painless. (My experience with most other tickets with Chinese vendors is that they seem to take repeated explanations to get to a good conclusion.)

So, respect to GB.

I received mine quickly, the proper XLM2. Good experience with GB. BTW, the lightly modded XLM (moved battery wire, bypass springs, 22 ga wire) outshines the stock XLM2.

Waiting over a month for mine and still, nothing.My tracking # never worked either and it was sent by Netherlands Post.Oh well, as soon as CNY is over I will contact them.

My first order was 22 days (shipped on 1/9/15 arrived 1/30/15). Placed a second order on 2/10/15 and still waiting for it (but only been 10 days). Hopefully it will arrive soon for you, waiting can be a test of patience sometimes. Still waiting on orders from Fasttech, DX and Ali.

O’well, like Christmas when they do show up. Only difference between men and boys is the price of their toys :bigsmile:

Ordered mine on 01/20/15 and received them on 02/17/15. Works great on my DST. Both of them are XM-L2. Now if I could only find tube that will fit on my 3D Defiant light that fits a 32650

What is people’s opinions of the drivers these F13’s come with? What is the size of the driver? Since I’m gaining experience with (or at least getting my feet wet) modding I’m thinking of changing a driver. I’ve replaced one star already with a 20mm Notigon XML U2 and have a second Notigon going into my second F13. I ordered two more that haven’t arrived yet but thought it would be interesting to have a one or two stock F13’s and then play with the other two in various ways to see what happens, what I like and foremost to get experience in doing various mods.

I was thinking of something like this: QLITE REV.A 7135*8 3.04A LED DRIVER - 17mm as I’m looking at using it in one or two SK98’s I have coming. Just unsure of the driver size at the moment. If this looks good, how many 7135 chips would ‘you’ go with? As with the SK98’s I’d like to have one bright and one max run time.

Thoughts welcome :slight_smile:

I have not been here long enough to have an opinion. The board is an oddball size of 22mm, which I why I bought this light so I can build and program this driver for it. I wish light makers would get away from the relatively tiny 17mm driver and go bigger.

I sure hope the LED is still loose (or at least poorly glued) to the shelf, as it is a cool white (which I hate), and must be replaced. Since the shelf is located deep in the body, it could be a bear to get out.

Most F13’s the star is loose, held down by the reflector

they are VERY good lights…go with a XM-L2, T6-4C for a good neutral tint…very very light creme tint to it but very smooth, my favorite tint

For a price like that I had to order one of these. Can’t wait for it to turn up!

That 4C is a nice tint and I’ve used hundreds of em in the big lights I used to make (with one red thrown in for CRI), but I’m a warm white guy when it comes to flashlights. I’ve always liked the 7 series tints for flashlights, giving up some lumens for tint and CRI. Cree has announced 90+CRI WW bins, but they appear to be vaporware so far. I got a nice 6A2 XM-L2 from Mountain, but I really like the 7s.

This light is going to take a while to finish, as this will be my first attempt at flashing a MCU. The flashing stuff is on order, but from what I’ve read, that’s the easy part.

You got bit by the bug….didncha :wink:

Where do you select XM-L2, T6-4C?

I’ve been bit for quite some time now. Been building stuff since the early 2000s. Shoot, I replaced my kitchen’s T-12 fluorescents with spare WW and high CRI LEDs, powered by Xitanium mains drivers back (I think) in 2009 and after a few thousand hours they are still going strong. Probably helped that I mounted the LEDs on aluminum channels and have 40mm fans blowing down said channels.

Anyways, I ordered a half dozen 22mm 12*7135 drivers from OSH. We’ll see how it powers this flashlight. This light, at a regulated 4 amps and less with a warm white XM-L2 could be a nice combo.

It feels good to be back in the saddle. I haven’t touched my flashlights (other than to use them) or other electronics since I sold the business 5 or so years ago. Now I’m starting over—with zero inventory and a lot fewer production tools.

You need a soldering iron, then buy the emitter on the board, and swap boards.
The links will show you how, and where to buy them

Missed quite a bit. I avoid reading threads even smelling of “mod”. Thanks.

That cool white XML-2…is this a good candidate for dedome?

I have modded my light purchased because of this thread. Kept the stock driver but changed the wires to 22 gauge silicone wires with the positive moved to the alternate location on the driver. Also added 22 gauge wire to both springs. With a de-domed XM-L2 0D on a Noctigon it has a good beam. I also polished the anodizing off the shelf, added Arctic Silver under the MCPCB, and shaved down the centering ring till it just barley engages the reflector. I am happy with it, especially for the money I have in it.

Edit to add:

Tail-cap current readings of 3.6A with protected 4000mAh Evva and 3.75A with purple Efest
