Well my black one just arrived today, it wasn’t a pre-order light, so I had to pay the full $35 + shipping. It’s all black like it should be, had the clear o-ring wrong on the lens, had to change that, only had 1 o-ring on the light’s body but there was 3 spares in the box so I put one of those on the body so now I have 2 black o-rings on it. I cleaned the little brass contact as it looked really black & dirty. Lubed-up the threads and put a battery in it, nothing, so I tried a few and I found that while they all seemed to fit just fine, keeppower 3400 (68.68mm), Panasonic 3100 unprotected, orbtronic 3400, nitecore 3100.

What worked just fine for me was a EagleTac 3400 (68.04mm x 18.48mm) no fitment issues what-so-ever with the EagleTac 3400, I don’t know why the Panasonic 3100 didn’t work since it’s “advertised” to work with the light, probably has something to do with the spring that is just dropped into the bottom of the light, the center of the spring is completely off; but for me I couldn’t get the light to turn on at all with the the panny.

I’m not complaining though because I really like the EagleTac 3400’s anyway and I have several of them on hand anyway. It’s a shame I had to take the lens apart and fix the o-ring and then clean the light up, but I’ve been following this thread and so it wasn’t a surprise, but for the money I spent I don’t think I really should have had to do that especially since my light wasn’t a pre-oder light, AND to add insult to injury I now see on cnqg’s website, the price price has dropped to $30 now.

Are you saying the 3400 mah protected Orbtronic did NOT work? I have an extra one of those and also a NCR 3400 mah protected panasonic cell which is 68.9mm, the same size as the orbtronic!

Thanks…….

If none of those work, I probably won’t get it.

2 Days ago I received my DQG tiny 18650 from CNQG’s black friday sale.
Unfortunately it does not turn on.
I tried different batteries but not the slightest sparkle comes out of it.
I already emailed them but have not got a reply yet.

But I was wondering if there is some known problem or something that I could try to get it working?

I have around 0% experience in repairing flashlights.
I already tried unscrewing the lens, head, body and tailcap and putting it back togheter again.
I once read somewhere that problems could be due to the clicky switch, but this has twisty so that’s not it. But to test that you should make a connection to the negative end of the battery and the bare threading. I did that with my multimeter. It gives me the battery voltage so the circuit is okay but the light won’t power on.

Is there anything else I could try or is it just a matter of waiting untill their customer service responds?
Thank you!

I also got it in wensday. I first noticed a bit ringy beam, second, it does sometimes flicker when changing modes, so, for example, when u switch it from low to medium or medium to high, if it flickers inbetween, you end up with low mode again. Always starts on low tho, which is not bad for me. And yes, it doesn’t like protected cells, cause of the flat – pole(reverse polarity protection). Also, the clip is very very tight. What else can i say? I got it 30% cheaper as Rick offered 50 coupons and was lucky to grab one on time so i’m not as bothered with the issues it has.

As a follow-up on my previous post.
Ric contacted me to help me find the problem.
It was the reversed polarity protection in the tail cap. After removing the foam in the tail cap everything works!
Thanks Ric!

I bought one in August, 1013. The light is bright and small. Great potential. But the firmware designer apparently failed to include switch debounce code, so that every time you rotate the switch off-then-on again it detects some random number of switches, and the mode it switches to is completely random. To get what you want you have to try over and over.

Remember though, firmware was in it's infancy in 1013. Laughing
