I plan on reflowing a XM-L2 U2 on a 20mm sinkpad, getting a 3.04A Nanjg and letting her rip…I figure that is a middle of the road muscle car kinda build…
Hopefully we will get to 50, but I am starting to see the point about too many GBs in such a short time... Live and learn...

There cant be to many group buys. Not everyone buys a light from every group buy so when the right one comes along we can participate. I'm in for two here the price is that good. Happy wives, do we really worry?

Im at 4,1A with a quite sophisticated Bocian driver in my "moderatly driven light". Also with a nice and rare tint. XM-L2 T5 5A3 80+ CRI. Turned it into a really nice light with great tint and UI.
XM-L2 U2 1A with 5,9A Qlite in my other light. Im not using that light as much as the other one... Just wanted to make a really bright F13. :D
I’m in for 1, looks like a good mod host.
Now just need some 26650 batteries…
The JingKong 4Ah still $6.75 at Lightmalls. I’ve been delaying buying 26650 but now I have BLF A8, HD2010 and now possibly this F13… maybe nearing time to step up. Panasonic might release 4Ah 18650 this year but the price will probably be 3x this 26650 in the beginning anyway.

Ive just received 2 of them jingkongs from lightmalls and at 1amp I can only get 2650mah

We are around 40 pieces now. I think we will hit 50, especially if I have GearBest do a "code" like we did with T-mart. That will spread around to other forums and that will give them over the 50 piece mark. Since there is no high limit, then it should be no problem spreading it around.
I have no need for this light. I’m in! 
Hi,
I’m probably in for at least 1, but is the driver for this light a 2-board driver? If so, does anyone know what the sizes are for the driver and the contact board?
Also, their website shows they use Paypal. Does the $9. price include PP fee?
Good for one.
It is a single board driver. It “Should be” like this one https://budgetlightforum.com/t/-/19164
The total is $9.99. There should be no extra PayPal fees.
Pencil mod is equivalent to resistor stack. If one works, the other will too.
In that case, then just a blob of solder should work as well. Just solder across to jump the component, or even solder a wire on. But, the reason for a resistor there is to control the time to reset, is it not?
Correct, if you solder blob it you will likely get stuck in the first mode (hopefully high). Solder blob may also cause other problems such as a high parasitic drain. I’d use a low value resistor (in the thousands of Ohms still) in place of it.
Playing with different high value resistors like discussed in your link (or just playing with the amount of graphite you lay down from the pencil) allows you to control the reset time.
Hi,
Ok, thanks. So that explains why the pics in the other thread show replacement with a 2-board driver, with presumably an ~20mm contact board.
I’m assuming that that also means that there’s enough space, height-wise, in the pill, to stack two PCBs (a contact board and a driver board)?
Can you now put me down for 2 of these?
Thanks,
Jim
