Ultrafire F13 at $11.39 - with Coupon Code - Gearbest

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

Is there any expiry date for the coupon code?

Finally received mine yesterday looks like a good mod light but first thoughts of the standard light was of low quality.

I just got 2 of them delivered yesterday… I paid $10 each… forgot what’s the code was, but it’s still working

Just open mine up to swap out the LED turns out they don’t use any thermal paste :open_mouth:

I liked them for $9 but $11.39 changes it a little. I knew I should have bought one more………. story of my life…

:exmark: :beer:

The later lights I received, which was along time ago, where of very poor quality which was also reported by others as well. I cant verify the quality now but would say buyer beware.

I’ve had good results from Gearbest. Takes a while, but it got there.

Just file a Paypal dispute, man. Insurance or no, Paypal will give you your money back. You have 6 months to file now.

i paid by credit card

Hello Challun, welcome of BLF.

I very much doubt if the code you were referring to still works.
Most codes have a limited time frame, and you are responding to a thread that was created in 2014.

It is even more unlikely if that code has anything to do with Gearbest.
a/ Today the attention of Gearbest is less focussed on budget lights with great modding potential.
b/ Today they offer less lights, brands unknown to me, with uncertain quality.
c/ They (because of COVID-19?) no longer have a rather special connection with the BLF community.

If I were in your position I would check out if:
1/ Gearbest is this selling this light.
2/ Any of the (very few) BLF-members that are still affiliated with Gearbest can offer you a code for it.

Seems he might have been a scammer. His link has nothing to do with flashlights, etc…
