Group Buy Feeler for the Ultrafire F13 from GearBest - Closed, See OP for link to GB thread now

[Gj1 (Gj)]

@wight

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.

I used a pencil on a clone (Paisen U2-Z6). The first time I overdid it and only had high, just erased it and penciled again a bit lighter. Mode change is perfect now, with about a 1 second reset.

I like the older version of the F13 more (my review ), because it has a removeable pill and it was easier to replace the LED and the pill has many threads. I use a pencil to get the mode result.
But the concept is nice, it's a good price and I think I will buy 2-3.

Noob question. Without any mods, what would be your rating for this light?

With an XM-L U2 at 2.4 amps? I think there’s a chart here somewhere. I would say about 500 lumens OTF, but that is just a guess.

Thanks Old-Lumens.
This is not good. Still have 4 new lights incoming. And now this. How will I explain this to the wifey? But I like the form and size of this light. So I’m in for one.

it’s easier to explain to your wife than I have to explain to my wife with 20 lights in a month of April alone :weary:

So true… :bigsmile:

For $10 you can put me down for one.

Sorry, I already have the Paisen, more 26650 lights than I have cells for, and more lights than I could ever use, so I couldn't possibly take more than three. More likely two. Don't even suggest four. Two is already too many.

Waiting for an intervention. :|

Buy two. Tell her one for you and one for her.

Either she buys that and you get one, or she doesn't, and given community property laws, you still get one. Along with lots of time outdoors at night to enjoy it.

5/9/14 00:24 Central time I will put the thread up soon, as soon as an error is corrected. Multiples do not take the code, so I am contacting GearBest now.

Sorry, it's always something, isn't it?

[MRsDNF]

Thank you sir for the effort so far.

Unless our flashlights come with free shoes, I don’t think she will buy it. I like lots of time outdoors at night :zipper_mouth_face:

5/9/14 00:24 Central time  I am putting up the actual group buy thread now, with the discount code. No limit on how many.

Enjoy

how long will it go for? Payday is next thursday! ARRGH

[Old-Lumens]

I went to the site and tested the code. It worked fine for only one light, but if you add lights, it goes away and goes back to the $13.94 price, so I just emailed them to correct it, but I have to wait for a response and for me to check it out. I jumped the gun, since they gave me the info, but, of course.... well you know.

So, I have to wait a little longer before putting up the GB thread.

So… you’re getting 6 then?

Thank you for a the time you spend setting up these group buys. I would be interested in buying one as long as it doesn’t come with next mode memory. I can’t stand Next Mode Memory. I am even fine with it starting on high with no memory. At this price I am sure we can easily hit 150 pieces or more. Manufacturer should be able to accommodate a driver change.

Already asked, they will not do a driver change on this particular light, at this price. On a more expensive light, they would “consider it”. There is a mod to get rid of the next mode memory here.

Old-Lumens;

Thank you for the link. Appreciate all the effort you put in.

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.

http://www.lightmalls.com/3-7v-4000mah-inr26650e-rechargeable-battery-yellow-1x26650-battery

Ive just received 2 of them jingkongs from lightmalls and at 1amp I can only get 3350mah

which jingkongs did you buy, the ICR or the INR? and did you have to pay for extra shipping to get the batteries? i’d like some 26650 for hd2010, xintd x3, and this UF F13 GB.
do they keep up the voltage better than 18650?

That’s no good!
I was going to order a couple of them, but I think the shipping cost some dollars, so I didn’t in the end. Instead I bought soshine and trustfire flames 26650 from gearbest instead. Haven’t received them yet though.
