DQG 18650 EDC--World's Smallest 18650 Flashlight

Inside diameter of my Ti coloured is also 18.7mm.
The battery tube is exactly 70mm deep and the bottom spring adds at least 1mm.

That titanium (looks green to me) is very nice looking. Are these still available to be ordered?

Yes, they can still be purchased : HERE

Would someone post a couple of beam shots showing off those TIR optics please?

Looks like mine are in town :)!

Edit: What’s weird is that I have two coming in, but they’ve arriving via different routes :)!

Mine flickers a lot and skips modes when twisting it, only solution is to twist it really hard to closed every time I turn it on or change modes.
The threads were gritty and dry, but a little cleaning and grease solved that.

Otherwise it’s got the perfect size, fits the palm of my hand nicely, and it’s brighter and throwier than my SC52 on 14500:s.

My Maratacs or Itp:s are a lot better when it comes to that, smoother and more consistent in their mode-changing.

edit oops… confused with a different light altogether… sorry!

Thanks. Not I know I should stay away from all of them :wink:

Has anyone been able to confirm the buck only or buck/boost nature of the circuit?

Does it drop out of regulation at a particular input voltage or keep upping it until the 2.5v ‘low voltage protection’ kicks in?

There is no boost and there seems to be no under voltage protection, at around 2.4V input it barely glows.
Tested with lab power supply and long cables and from 3.8V it gives the full ~1.9A on high, I tested up to 4.5V and it was the same current.
I got the XM-L2 version.

Thanks for that. What voltage does it drop below 1.5 amps draw?

Hmm can’t get a stable current reading and tell for sure.
If I try with 3.3V it seems to be to low for 1.5A but it’s fluctuating up and down.
It also seems to warm up very quick which makes forward voltage go down and make it pull more current.

I can’t believe this: Been waiting for these for so long, and they arrive at my house today, but REQUIRED SIGNATURE, and no one was home. AARGH! Now I have to wait for another night/day to get them :)!

I so love that when it works… and absolutely hate it when it doesn’t… at least you have a delivery tag… my mailbox had bills in it….

Got mine this morning, from the post office. :bigsmile:

This thing is almost my holy grail of lights.

Almost? How does it compare to your TN31?

N4UD

It’s a lot smaller ! :wink:

Assembled length = 9cm
Body is a simple 7cm ano tube closed at the tail.
6 front threads, an O-ring groove, no tailcap.
Some knurls, steps, and a clip groove and clip.
Very light.

4 coil 1cm high spring is jammed into the base.

The head is 2.5cm long, 2 threads screw on SS bezel, O-ring, TIR.
The pill and driver are behind a partition with the LED poking through a hole.

Colour: kind of olive green/khaki.

Tiny 18650, 3 mode.

Could be my next standard for EDC lights.

More of an EDC then a SC52 or the XIAOZHI?
