Ultrafire F13 at $11.39 - with Coupon Code - Gearbest

I received a prompt response and promise of a replacement XML2 F13 for the XML-T6 I received.

Thanks OL!
I modded the XML-T6 per your posts (braided springs, moved + wire, sanded down reflector spacer, etc)
Now it rocks!!
:slight_smile:

I have bought like 14x from this light

Quick question on this (to OL or anyone); I’ve haven’t yet gotten into any modding, though it sounds interesting and a lot of fun. Do all lights need this thermal paste or just certain ones? For example, I have lights like the Sipik SK68 and SK98 as well as the TF A8 and now the F13’s are on the way (as well as various no-name lights from different sources). Would it be advisable to put thermal paste on all of these types of CREE LED lights? And if so, is there a good instructional vid to look at to know where and how much and any other tips and tricks? This sounds like something that I need to learn to do but want to learn to do it right.

Thank you :slight_smile:

Thx OL! Just ordered 1. $9 bucks and you can’t go wrong!!

Paste is an absolute must. The thinner the layer, the better. Most lights come with it already… you’d be able to see a white-ish paste oozing out from under the star if there’s enough there. Dunno about videos, but just be sure you don’t let the reflector short out the leads going to the star when you reassemble.

For more information look into CPU heatsinks in the PC community, but ruffles has really covered all your bases already.

One way to apply a grease type TIM (thermal interface material) is this:

Okay, thank you both. Looks like I’ll have a little project to do with my lights.

Received both of the F13’s I ordered in the OP. That was 18 days in transit which isn’t that bad. It comes with an 18650 sleeve and a 3xAAA holder which is nice to have those two items included. I tested both out with a Trustfire Flame 26650. The hot spot is tighter than the A8 that I have so it puts a bit more light into a smaller more focused area. The spill isn’t quite as bright as the A8 but still quite bright. What this means is the throw seems to be even farther than the A8 while the overall lumens looks to be similar. I have no way to measure lumens but it is easily as bright as the A8 overall. The O-ring is glow-in-the-dark which is also a nice feature.

Overall it is a really nice light and for $9 an incredible deal. It is slightly larger in length than the A8 and the front have is larger in diameter. I’ll probably still carry the A8 as my primary deep woods light, but it will be a hard choice. The determining factor may be if it fits in the zippered pouch on top of my hiking bag or not. But it will make an outstanding back up.

I really appreciate the heads up on this deal, thanks OL :slight_smile:

For a $9 light you might as well do the ‘standard’ mods at least. (Move LED+ wire, pencil the capacitor, and bypass the springs if you’re feeling daring.) That might tip the balance. :wink:

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.
