Fit and Finish
Overall finish is excellent. Bezel, button, and clip all appear to be stainless steel, and the anodizing feels great. In the 2 weeks that I've had the light it hasn't collected any major scratches, the only wear that I see on it is some light scratches in the groove where the pocket clip attaches. The pocket clip itself is very stong, bordering on too stiff. It is reversible, but you wouldn't want to switch it too often because it is a pain to do and can scratch the light. Knurling is very aggressive and provides great grip. As is common with DQG lights, there are slight variations in anodization color/shade. Mine matches the gearbest listing with the body being slightly lighter than the head, and the head slightly lighter than the tail. The DQG model etching on the side is fairly light, it looks uneven and worn even though the light is brand new. There is a GITD O-ring inside the bezel, but the 'glow' isn't very strong or long-lasting. The thin threads of the tailcap are somewhat easy to cross-thread, but once they are alligned they are smooth and came pre-lubed. Despite these few quibbles, the light feels decently high quality in the hand, even though it is very light.

Operation
When you first pick up this flashlight, you will probably hate the UI, I know i did. For someone new to this light, it will be counterintuitive and you might even have to read the instruction booklet (which was inlcluded). However, after growing accustomed to it I have found it to be fairly easy to use and memorize.

From off:
1 click: Low
2 quick clicks: Med
3 quick clicks: High

From on:
1 click: off
2 quick clicks: Next mode (Cycle L,M,H,L,M,H )
Hold 1sec: Turbo

From turbo:
1 click: last used mode (then additional click for 'off')

Turbo is only available from an 'on' state and only by holding for 1 sec. Turbo has 60sec timer then drops to the last used mode. Holding from off does nothing. This is a good thing for anyone that plans to carry this light because the button sticks out from the body. The UI makes it very difficult to accidentally activate anything more than low mode. Tail lock-out is also possible.
The beam pattern is very useful in my opinion. It has decent throw for such a small optic, with a smooth, well-defined center spot and nice spill around it. I have the NW model and the tint is pleasant although leaning just a bit towards the green side. There are some faint blue "cree rings" around the outside, but you won't see them unless you're white-wall hunting. Modes are visually well-spaced.

Measurements
As you might (and should) assume, this is a very compact light. It is by far the smallest 18650 light I have ever seen. It is close to the same size as a typical AA/14500 light. The tailcap/thread design allows for a bit longer batteries than the tube length may sugggest.

Amp draw measured at the tail with Samsung 20R.
(High and Turbo varied a lot, not sure from heat sag or what, so I list a "mental average")
Off (vampire draw) 1.5 microamps
Low: 0.01a
med: 0.18a
High: 0.78a
Turbo: 2.1a

Body measurements:
Length: 88.15mm (with Samsung 20R installed)
Length: 92.52mm (with protected Samsung 26F installed)
Head diameter: 24.04mm
Tail diameter: 23.63mm
Battery tube depth: 65.16mm (Batt+ contact -> end of tube)
Max battery length: 70mm
Battery tube internal diameter: 18.84mm

Modding Forecast: Cloudy
DQG did not make this light to be tinkered with. The head is glued to the body; you would need a torch or strap wrench to get it off. The same can be said for the bezel. Even if you were able to get inside of it the construction is not typical to our other budget lights. To save space, there isn't a pill with separate shelves for driver and emitter. There is one shelf below the optic, and the driver and emitter are contained on the same board. This is probably why DQG resricted it to 2.1a with 60sec timer; it can't handle very much heat.

Conclusion

Pros:
Tiny size for an 18650, good overall feel, great grip, usable beam pattern, plenty bright for most uses.

Cons:
Small issues with fit/finish, driven somewhat lightly by our standards, aggressive knurling could wear on insides of pockets, UI takes some practice.

Final word: If you want to EDC an 18650 light, this should be on your list to consider.



Some of my pictures do not correctly show the color of this light. This color is correct:

The light becomes 4+ mm longer with the protected cell- so the light is really not long enough for the head and tail to tighten down?

Looks interesting. Quality looks better than previous DQG lights I've had. The UI sounds identical to mode 3 on the Noctigon Meteor M43. Vinh made a set of videos explaining the different UI modes. See:

http://www.candlepowerforums.com/vb...Best-of-2015&p=4656934&viewfull=1#post4656934

I wonder if you can switch UI modes on this the same way as on the M43? If it uses the same driver then it probably supports it, but maybe doesn't mention it in the instructions anywhere.

Edit: Just looked at the M43 modes again and it's not identical, but sort of a hybrid between modes 2 and 3. Still remarkably similar though considering that AFAIK there are no other lights with a UI remotely similar to these.

It's hard to explain how the tailcap works. It has an aluminum "nub" surrounded by a compressible foam, and there are more tail threads than usual. It "adjusts" to the extra length, but doesn't feel any less solid.



From what I know of the development of the meteor, I doubt they are related in any way other than perhaps inspiration. Its definitely not the same driver.

Yeah, probably using the wrong terminology here, but possibly using the same controller (not sure what type of chip these circuits generally use), but clearly not the same circuit! There's quite a difference in wattage :)

The similarity is an awfully big coincidence though.

This. The DQG's battery compartment is really quite ingenious. There's a post at both ends... no spring at all. Surrounding the post at the tailcap is a foam donut that's slightly taller than the post. The tailcap has far more threads than normal, and the portion of the tailcap that sits over the o-ring is also much longer than normal.

The result works extremely well:
1. The battery compartment fits ANY length of 18650 cell.
2. Batteries are tightly held in place and don't rattle around.
3. Due to the foam donut, the light maintains the ability to have tailcap lockout without the batteries rattling around.
4. Due to the extra long shroud over the tail o-ring, the tailcap remains water-tight regardless of what 18650 is used.
5. There is no wasted space and almost no air in the battery compartment. The light self-adjusts to any length 18650. Use a shorter cell and the entire light gets shorter.

I just realized I've been saying "DGQ" instead of "DQG". I've edited the OP, is there any way to change the title?

No visible flicker or PWM that I could see.

Also according to CNQG's sales page, this light is current regulated.

I have been very happy with my DQG Tiny III 18650. Relatively new to this whole light forum thing, but I think the levels are spot on for what I use a light for. I did not have the twisty version, but I have cycled the button on this one in excess of 1000 times so far (ok, when I get bored you can tell from the light levels changing in the room I am in...) with no issues. I occasionally short stroke the button myself when I am just playing around, but that is not the buttons fault. The tail cap is quite a good design for fitting all types of 18650 batteries I have in my possession, one of those "why didn't I think of this" solutions. Overall a nice light for someone that has not used a lot of lights. Easy to carry as well...

I finally managed to mod this thing. I replaced the driver with a FET driver from Mountain Electronics and the emitter with triple XPG2.

This thing was a royal pain to mod initially. It's impossible to separate the head from the body using any normal method. They must've used a ton of threadlocker. I think it would require cooking the light at 350 degrees+ to melt the threadlocker to separate it, and doing so could destroy the switch and damage the anodizing.

Without removing the head, it was impossible to remove the original driver board. I used a drill and drilled out the center of that board leaving just a few mm left around the edges. Then I scraped off any remaining SMDs and used the remnant of the original board as the frame to attach the new driver and the copper heatsink for the star. This method worked great and now my DQG 18650 mini clicky is now sporting a new interface, triple XPG2 and around 1700+ lumens at turn-on with a fresh cell.:twothumbs It gets hot fast though.

I'd prefer heat protection shut down to timed shut down on turbo. If 2.2 amps gets hot that fast 1.5 amp max would be better imo. There is no real high power. High should be 1 amp imo.

Actually the light with the stock driver (2.1 amps turbo I think was reported) gets slightly warm at the head, but not really hot. That's not heavily driven for a light these days, but then again the stock heatsinking in this light is awful. The LED is mounted in the middle of the driver board. The board itself appears to be the standard plastic PCB... it's not metal. And unlike the earlier DQG twisty 18650 mark 1, there isn't even a shelf from the head extending over the board. Basically, its like having a hollow pill with the LED mounted on plastic in the center.

My modded DQG18650 Tiny III gets hot fast on Turbo, but it's running with a FET driver and powering triple XPG2. With an IMR cell inside it should pull around 7 amps. Also, I added a copper heatsink and a path for the heat to get from the LED star to the exterior of the head.

It doesn't get hot because the heat stays on the board. Of course that is a bad thing. I just don't like such a rapid huge step down.
