I loaded up on them for $10, but for $9, may have to buy a couple more Smile. These fit the 40mm NiteCore filters well (at fasttech) or this cheap one: fasttech-diffuser, as other common 40mm lights, such as the SupFire L5, SolarStorm/FandyFire K2.

Also fit the Olight M22 filters http://www.fasttech.com/p/1311103

I am thinking of building a triple led flashlight. Is this a good host for it? Any build example?

Seems like a decent plan! You’re thinking of installing a 35mm triple? You’ll need a spacer of course. The stock flashlight uses a glass 37mm lens, so you may be forced to butt the triple optic up against the glass lens so it doesn’t fall out. I’ve been thinking about trying a triple with one of these myself. I can’t think of any build threads for F13 triples, but it should be similar to DBCstm’s Eagle Eye X6 triple builds.

Note that these should be the latest version of the F13 (same as the previous group buy on the same units from GearBest), they do not have a separate pill. I don’t necessarily agree with freeme’s conclusions, but the pics and information are all accurate and worth your time: freeme – UltraFire F13 mod issue ~ mini review included

EDIT: I have just measured the lens opening on an Ultrafire F13 from the previous Gear Best group buy. I got 33.8mm; IMO that should be plenty to keep the 35mm optic from falling out without leaving the glass in place.

Still fine, still on a break. One day I’ll catch up with you folks! previous wight catchup Wink

I ordered 2 more. With a little work it should be able to mount the Cute triple XML optic that everyone is using for the EE X6.

I am considering it, since a 26650 would be nice for a triple……anybody considering this?

I would consider it if someone offered the correct spacer for sale. I have no way to fabricate my own

I like big pictures and clear instructions. I modded my light from these 2 posts from smart blf members.
I wired springs, larger emitter wire, connected at new + terminal and made a stinkpad.
Total cost for wire and solder? Maybe a few cents.
Light is very good now. Fun project.

Awesome, great job! Gotta love the ingenuity of making a stinkpad, if for just making it a DTP (direct thermal path) star vs one with the pcb substrate under the emitter thermal slug

If this doesn’t fit that AA battery holder, does anybody know of a light that will fit it?

 

It think most 26650 lights take 4AAA holders.  I usually solder a piece of copper tubing with a little disk to the holder or to the driver to make up the vertical difference.  Much less capacity, but at least you get the voltage up a bit for better performance.

Yes, this light will run 4xAAA with much better output than 3xAAA.  See my review of the original F13.

Thanks for your input. Yes, I will follow DBCstm’s Eagle Eye X6 triple build (35mm optic, 3 XP-Ls, and 32mm noctigon). I will order one of your FET driver boards from OSH Park (maybe 17mm FET+7135 driver, so I can use it for other lights) and figure out how to make a spacer.

Thank you OL Smile

BLF member ‘can’ directed me to this thread and I appreciate it. Just ordered a couple of them. Back when I first got into 26650 flashlights (which is about the time I learned what a 26650 battery was Wink ) I was torn between the TF A8 and an F13. Both were recommended here on BLF. I ended up getting the A8 (actually two of them because my wife took my first one) and it has become my favorite flashlight. Purchased both for $17 each (one on Amazon and the other Ebay) as I wasn’t yet familiar with websites like GB/DX/FT etc. So for the price of one A8 I can now get two F13’s and I’ll be able to compare them. And nice to have a second 26650 light as back up.

Thank you again.

Gotta love OL, “or clone”. Has anybody ran this with 3xAAA or such?

This is one of the reasons I like my TF A8 in that it can use three different battery options (26650/18650/3xAAA). I’m glad to know this one can do so as well. I think options are important.

The F13 is a good budget light at this price.

http://www.fasttech.com/product/1424810-trustfire-tr-a9-2-cree-xm-l2-t6-...

This TR-A9-2 would easily fit that 3xAA Carrier from Gearbest. The Lumintop SD10 4xAA Carrier would probably fit in the TR-A9-2 also. I think the TR-A9-2 had a bad pill thermal design though. Too bad.

Got my F13 today. Wow, very nice light for the money. Thanks for the code OL! Smile
Had a bit of a panic when I opened it up. The star clearly had XML-U2 written on it. Shocked
Closer inspection revealed that the emitter was XM-L2 after all. They must have been using up old stars. Phew!

Hmmm me thinks I’ll put a bit more solder on that positive joint.

The writing on stars should never be trusted. Most of us ignore it as a point.

As long as you’re in there soldering stuff, you may as well remove the star and add some thermal grease under it if there isn’t any there already.

Thanks for the pic, looks like a nice solid shelf. Although the anodizing on the shelf isn’t great.
Look forward to getting mine.

They are good lights right off the shelf and better when they have a good copper star and a nicer driver put in. 5 amps is not unreasonable, since they transfer heat well. Glad y'all are having fun with them.

That’s strange.. Got mine today too. But on the outside it says “XML-T6” – and that’s what’s inside – so it seems. It is only an older XML with green top, 3 bond wires and 6 stripes. On a grey star with no other text than +/- signs on it. Let’s see what the customer service has to say about that…

+ 1 From the Deal Alert thread.
Nice build for the price. It won’t quite lock out by unscrewing the tail cap after some wear, because some aluminum shows through the anodizing on the threads. I have not opened it up.

Flashlight designers should look at lighthouses and pottery.

Anyone stuck an MTG2 in one of these? I’m thinking of picking a few up.

The new XHP70 and XHP50 might not work too well with this reflector.

"Whoa that's a bright light!" ... Yea I guess.

I’m tempted to buy another one of these,the only thing holding me back is the first one I got from a earlier GB. The tail cap is very loose on the threads, it wobbles side to side when screwing on and the threads don’t look like they will last long. Is this normal for the F13 or did I just get a bad example?

Now that you mention it I did note mine being a bit loose as well. The tolerances could have been a little better, certainly. Once tightened up it’s rock solid though. Given the high number of threads on there I can’t see it being much of an issue anyway, as they’re not under any great strain.

Yup, it’s on the ‘to do’ list, thanks. Dry as a bone under there, as expected.

I’m thinking customer service will tell you that they sourced these leds by sweeping up an old flashlight factory floor. Anything that end up in the bin at the end of the day wandered it’s way into these lights Wink
These leds are almost always terrible bins and need to be replaced so I wouldn’t worry too much about whether it’s a gen1 or gen2.

Just get a nice XML2 on copper and swap it over, it will cost almost half the price of whole light but it’s worth it. Smile
