New DQG Tiny 26650 7x XP-G2 2,500lm!!

A new DQG tiny 26650 just showed up on BG: http://www.banggood.com/DQG-Tiny-26650-3th-7x-XP-G2-CW-2500LM-4modes-EDC-LED-Flashlight-p-1110730.html

7x XP-G2, 2,500lm, 93mm lenght! That is about 25mm longer than the cell it uses. I never bought a DQG before but this one seems to be a good start Wink

Specs translated from Chinese taobao store:

——————————————————————- Information update bar – —————————————————————-

(Coming soon)
This version compared to the previous version of the improvements:
1. Increase the output capacity of the stall, where super-bright stall almost doubled, from three to seven amplification, still maintain the original volume.
2. Re-create the structure, the more lean.
3. Increase roll tail cover design.

D.Q.G Tiny 26650 3th Flashlight

It is the world’s most compact single section 26650 lithium-ion battery-powered 7-power LED flashlight, only 91-96 mm long, 31-38Mm in diameter. T6061 aluminum alloy surface of the body hard to do fine for car oxidation process, the first ring of stainless steel and refined side to press the switch pressure ring embellishment, modeling simple, compact. Weighing only 93 grams, and finally the 26650 Battery giant flashlight into the EDC areas, it is to carry an excellent companion.

Specially designed PMMA lens to form the desired light range
GITD lamp luminous effect
Tail stand mode
Anti-anti relieve over-discharge protection
High reliability, waterproof design
26650 Compatible Battery size: maximum diameter 26.8 mm, maximum length: 70mm (not recommended to use a protected 26650 batteries, battery size may be due to excessive and circuit current limit protection that does not work)
CREE XPG2 using high-power high-efficiency LED, life over 50,000 hours.

Advanced high efficiency constant current control circuit, has a 4-speed output brightness:
Extremely bright: 2,500 lumens (90 seconds after the turn highlighted);
Highlight: 800 lumens / 2.5 hours;
The bright: 250 lumens / 8 hours;
Low light: 8 lumens, 200 hours. (Data 5000mAh capacity battery as a reference)

Instructions:
Unscrew the end cap, a 26650 lithium battery cathode lamp mounted above specifications toward the barrel body, tighten the end cap, this time the torch is in the standby state.
In standby mode: Click the button to turn on the bright side; double-click on the highlighted; three strikes and low light; press 1s turned super bright.
After the boot: hold down the switch to perform high-low cycle, let go to keep the currently selected gear; double-click to open ultra-bright, 90 seconds after the downshift to highlight (or double-click to exit during Super bright return to the previous position); click shutdown.

Precautions:
Super bright stalls tremendous heat, being careful not to super bright continuous dimming gear.
Prohibited for children, non-irradiated others and the light source directly or animal eyes, glare can cause discomfort or even injury; rigorous brachytherapy skin, to avoid being burned or allergic reaction to light.
Use cover is placed on the desktop, super light and heat output may cause overheating of the torch and related materials and even cause a fire hazard in non-shaded lamp light parts, or torch is open.

That is pretty cool, it solves the feeling that I always had that the head of the 26650-tiny could have been narrower.

Now it would have been nice if DQG with this model took the opportunity to fit their neutral version with high CRI 219C Nichia’s. Assumed that their main customers are flashaholics, it would help the sales.

I never bought a dqg either, but this is my favorite generation so far. Oh so tempting. All the dqg lights are nice, just never liked the UI. It either requires you to hold switch to turn on or off….or both.

Shocked

I have 2 DQG’s.. The AAA titanium and the AA SS twisties.

Still going strong after a couple of years, although the AA gets infrequent use due to its weird interface.

The AAA gets used regularly though, and is a great and super tiny flashlight.

Interested in this, although the price is hefty.

One-piece TIR lens. This is not good IMHO

7 up at that diameter is going to be floody no matter what the TIR specs…

Any chance of getting A6/Bistro firmware in there, even with a replacement driver? I’d like a couple modes between turbo and high, and an even lower low.

Otherwise I’m all over this one. Smile

Im 99% sure that stock driver is boost.
And there is no need in lots of modes if they are not fixed.

Why would it be boost? It’s possible to run 1S7P with these LEDs with a single cell.

And I’m not familiar with DQG’s UI, are the modes infinitely variable? Still, I’d rather have 7 modes than 4. Also I’m STRONGLY against mode memory, I’d prefer it to be user selectable.

I think It’s likely boost because it is easier to work with high voltage than high current, driver swap is possible but you would need a custom pcb with room for the electronic switch. DQG lights aren’t known for handling heat and even at the stock turbo level I don’t think it could last more than a minute… I hate mode memory too, I like direct access to lowest and highest modes.

Yeah, I wasn’t thinking of running higher than stock turbo, more of a “turbo lite” at something like 1200-1500 lumens for a smidge longer.

I was playing with my BLF A6 for the first time in a while (it was my favorite light in Afghanistan), and I remembered why I liked the interface so much. Smile

Also, learn me something. I thought to do boost, you need LEDs evenly divisible by the number of channels – for 2S you need 2, 4, 6, etc. LEDs, for 3S you need 3, 6, 9, etc. LEDs. I cannot see how to wire up 7 LEDs in anything other than 1S. 1 channel running 3S1P and another running 4S1P would have some of the LEDs getting either too much or too little power. 7S1P just seems silly to me, the losses from boosting that much would be worse than just running DD high current I figure.

Oh it makes sense… 7S is 20V+ Vf!

You can drive leds as 4s2p with extra diode in one half of circuit. With about 3v voltage drop on this diode youll never see difference in led current.

Thanks kiriba-ru, I had never thought of that. Would the extra diode create much heat?

I still want this light, even if I can’t change it much.

Thank you
I was using the link in the op’s first post and it goes to a CW. It gives no options for a NW.

Ah yes. Banggood has a separate link for NW. Hopefully if OP gets a coupon code it will work for both models.

In the pics it appears that the black one is slightly longer than the grey one. Especially noticeable in the 3rd pic. Is this some optical illusion?

Another light with bad mode spacing. Facepalm There’s at least one missing level between the 8lm and 250lm mode. More likely two based on their other modes. Like ~25lm and ~80lm.

And the output between 8 and 250 lumen is so important for such a compact light; at least to me. Anyhow, I was never charmed by DQG anyway so lucky me. Very interesting light nevertheless…

Same as extra led in the most simple solution.
This not too much as you can think for the first moment. For example 6×7135 linear driver with xp-g3 will give 3.2×2.1=6.72w and will consump itself (4.2-3.2)×2.1=2.1w on full charged cell.

I was interested, but the bad level spacing turned me off.

This is so easy to do right, yet almost no flashlight maker does. It’s not very hard to evenly space the brightness levels on a suitable power law curve or log curve.
