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 :)!

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.

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….

Almost? How does it compare to your TN31?

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?

Hi Guys ,

Here is to inform you that the factory made a mistake when assemblying DQG 18650 O ring,Which makes the beam a bit ringy (as “the” said in his post).

Here is the right way to install Head-O-Ring.

Below is the Optic lens picture, The O ring should be installed to The “Green” position.

Could you please take out the head o ring and install it again? It will make the beam perfect.

It’s very easy. Only 2 steps

1. Take the Head O-Ring off

2. Install the O-ring to Right position.

Thanks
Ric

Are you saying that the O-ring is in one position (green?) and to move it to a different position (blue?)? It’s hard to see the lines on the interior of your drawing.

Edit: Or did you mean to move it from the blue position to the green position? FYI, I don’t have the lights yet, so can’t visualize it :).

Wouldn't the ring in the blue position be a lot smaller though?

No. The O-ring was installed between TIR and bezel, but it should be between TIR and body.

I'm currently testing the effects of this change.. Please stay tuned.

My guess is that it means that now the o-ring is just in front of the tir but should be just behind the tir. (without having received the light Laughing)

(edit: you beat me to that _the_ )

Yes. That really helps! No visible rings and wider, smoother, more even flood. Smile

 

Before:

 

CW updated, NW original:

 

Both updated:

 

CW change as mouseover (mouse over for updated):

Unscrew bezel

Remove TIR lens

Take O ring off the groove on the front of the lens

Insert lens into bezel then drop O ring into place on the back of the lens

Put the bezel back on……done

Yes, it’s much smaller than the Xiaozhi, but not as tactile (not tactical) as the C303.
I don’t have an SC52, but do have these:

DQG AA, 270-T80, Xiaozhi, Convoy S2, DQG Tiny 18650, UF-2100, C303, Ultrafire S5, Small Sun ZY-C1 (16340)

Hi RIC,

Actually, so this brings up a question: The original place where the O-ring was had a groove, like it was meant to have an O-ring there. Since we’re removing the O-ring from the TIR lens, is the water-proofing still intact? Seems like water could enter from the front of the lens?

Thanks, and thanks also for these lights!

Jim
